1.5 IMPORTANCE OF THE PROJECT
The distillery industry today consists broadly of two parts; one, potable liquor and the industrial
alcohol including anhydrous ethanol for blending with petrol. The potable industry producing
Indian Made Foreign Liquor and Country Liquor has a steady but limited demand with a growth
rate of about 7-10 per cent per annum. Over the years the potable liquor industry has shown
remarkable results in the production of high quality spirits. Indian liquor industry is today
exporting a sizable quantity of Indian liquor products to other countries. The world alcohol
consumption pattern for different applications for the year 2013-14 is given in table 1.2.
Table 1.1: Consumption Pattern Of Alcohol For The Year 2013-14
Sr. No. Alcohol Consumption for (%)
1. Potable and Industrial 17.48
2. Fuel 82.52
The ethanol of commerce contains about five per cent water; hence, termed as "Hydrous
(water-containing) alcohol". If the last traces of water are removed, "Anhydrous alcohol" (water-
free or "absolute") is obtained, which is used to mix with petrol.
The world total ethanol production in the year 2011-12 was 102.58 Billion liters and major
consumption of alcohol was for fuel purpose. Many countries, including Brazil, USA, Canada,
Sweden and China have already started using anhydrous ethanol for blending with petrol. In
India, the Central Government has taken a policy decision to start using anhydrous alcohol (fuel
ethanol) for blending with petrol. Thus, it is expected that the demand of alcohol for fuel
purpose is going to increase in coming years.

1.5.1 Scenario for India
The Cabinet Committee on Economic Affairs (CCEA) of the Central Government has approved a
proposal for implementation of the ethanol blended petrol (EBP) programme in the country. As
a result, in January 2013 Petroleum Ministry floated a tender for supply of ethanol. As per the
tender ethanol requirement was 1404.10 million liters for 5 % blending for 20 States and 4 Union
territories and 315.20 million liters for Maharashtra for 10 % blending.
1.5.1.1 Industrial Alcohol
Ethyl alcohol is an important feedstock for the manufacture of chemicals. These
chemicals are primarily the basic carbon based products like Acetic Acid, Butanol,
Butadiene, Acetic Anhydride, Vinyl acetate, PVC etc. Figure 1.1 shows the different
important chemicals that could be made out of alcohol. The existing plants such as
synthetic rubber requiring large quantities of alcohol will grow to a larger capacity.
Acetic acid and Butanol needed in pharmaceuticals, paints and in other areas are
important industries as they are value added products.
The shortage of alcohol is widespread and it has hit most of the chemical, drugs and
other industries. The drug industry is also influenced by the scarcity of industrial
alcohol. Producers of insulin, antibiotics, tonics and several other essential bulk drugs
and finished formulations are unable to obtain their quota of industrial alcohol at
cheaper rate which is a vital raw material for them. Thus it follows that the supply of
industrial alcohol to chemical and drug units in the country will remain below normal for
some more time. In order to maintain proper rate of growth of industries, production of
alcohol must be increased.
1.5.1.2 Potable Alcohol
Chapter I
EIA Report: New Molasses based Distillery project
Udagiri Sugar & Power Ltd; Dist. Sangli, Maharashtra
1-6
The use of alcohol for the purpose of potable liquor is as higher as its use for industrial
purposes. Alcohol is used for manufacture of country liquor consumed by common
masses. This is manufactured by diluting rectified spirit with water to different grades of
250 UP strength. Different varieties are produced by addition of flavors and are called
spiced liquors.
Good quality liquors are manufactured in a synthetic way to imitate Foreign Liquors like
Whisky, Brandy, Rum and Gin, which are called as Indian-Made-Foreign liquors (IMFL). It
requires alcohol of high purity. For this purpose, separate distillation plant to redistill
and purify Rectified Spirit is necessary. This alcohol is called as Extra-Neutral-Alcohol
(ENA). It is also useful for manufacture of cosmetics and perfumes. As a source of
income to the Government, the potable liquor units get an assured quota of alcohol.
1.5.1.3 Demand and Supply Gap
Based on information from various sources, it is anticipated that demand for alcohol in
the Maharashtra state, could be about 700-740million litres, as detailed in table 1.3.
Table 1.3: Demand for alcohol in the Maharashtra state
Industrial 200 - 240 million liters
Potable 150 –170 million liters
Fuel 330 million liters (For 10 % blending)
Total 700 – 740 million liters
During last few years, substantial quantity of alcohol (R.S., ENA and fuel ethanol) from
the country has been exported to mostly Africa and countries of South-East Asia. During
2013, about 230 million liters of alcohol was exported from India.
The demand of alcohol for industrial, potable & fuel alcohol in Maharashtra as well as in
whole country will increase significantly in coming years. The proposed 30 KLPD distillery
plant will contribute in fulfilling the alcohol and fuel ethanol requirement of
Maharashtra and neighboring deficit states.

In the present scenario, sugar industry is forced to explore the alternatives so as to
attain financial viability while producing sugar. Distillery is one such alternative, because
of the availability of molasses as a raw material, bagasse as a fuel, own power
generation ability and availability of the steam energy from own sugar factory.
Therefore, the management of the factory has planned to establish a 30KLPD molasses
based distillery within existing sugar factory premises.

Figure 2.1: Layout of Sugar and Distillery units 2.3 TECHNOLOGY AND PROCESS DESCRIPTION
Proposed distillery unit is designed for continuous fermentation process.
2.3.1 Continuous Process
In this process fermentation and distillation is coupled to get a continuous supply of fermented beer
for the distillation column. Yeast is recycled. The advantage of the process is highly active yeast cells
initiate the fermentation rapidly and the alcohol yield is also much higher compared to the batch
process.
Molasses is the chief raw material used for production of alcohol. Molasses contains about 50% total
sugars, of which 30 to 33% are cane sugar and the rest are reducing sugar. During the fermentation,

yeast strains of the species Saccharomyces cerevisiae, a microorganism belonging to class fungi
converts sugar present in the molasses such as sucrose or glucose into alcohol. Chemically this
transformation for sucrose to alcohol can be approximated by the equation.
Thus, 180g of sugars on reaction gives 92g of alcohol. Therefore, 1MT of sugar gives 511.1 kg of
alcohol. The specific gravity of alcohol is 0.7934 hence; 511.1 kg of alcohol is equivalent to
511.1/0.7934 = 644.19 liters. During fermentation other by-products like glycerin, succinic acids etc.
are also formed from sugars. Therefore, actually 94.5% total fermentable sugars are available for
alcohol conversion. Thus, one MT of fermentable sugar will give only 644 x 0.945 = 608.6 liters of
alcohol, under ideal condition theoretically. Normally, only 88 to 90% efficiencies are realized in
Continuous type plant. Molasses containing 47% fermentable sugars gave an alcoholic yield of 283
liters per MT. Molasses, diluted with water to a desired concentration is supplied continuously to the
fermenter. Additives like urea and de-foaming oil are also introduced in the fermenter as required.
There is an automatic foam level sensing and dosing system for de-foaming oil. Every kilogram of
alcohol generates, about 290 kilocalories of heat. This excess heat is removed by continuous
circulation of fermented wash through an external plate heat exchanger called the fermenter cooler.
The fermenter temperature is always maintained between 32-34oC, the range optimum for efficient
fermentation. The yeast for the fermentation is initially developed in the propagation section. Once
propagated, yeast recycling and continuous aeration of the fermenter maintain a viable cell
population of about 350 to 500 million cells/ml. Fluctuations in the yeast count of +/- 20% have little
effect on the overall fermenter productivity. Yeast cell vitality, which is usually above 70% in times of
stress drop to 50% without affecting the fermentation.

Figure 2.2: Schematic of distillery process
2.3.1.1 Propagation
The propagation section is a feeder unit to the fermenter. Yeast, either Saccharomyees cereviseae or
Schizosaccharomyees pombe (the choice being determined by other process parameters, mainly the
downstream effluent treatment system) is grown in three stages. The first two stages are designed
for aseptic growth. Propagation vessel III develops the inoculum using pasteurized molasses solution
as the medium. This vessel has a dual function. During propagation, it serves for inoculum build-up.
When the fermenter enters the continuous production mode, propagation vessel III is used as an
intermediate wash tank. Propagation is carried out only to start up the process initially or after very
long shutdowns during which the fermenter is emptied.
2.3.1.2 CO2 Scrubber and Recovery
The carbon dioxide produced during fermentation is scrubbed with water in packed-bed scrubber, to
recover alcohol. The water from the scrubber is returned to the fermenter. In some industries, carbon
dioxide is captured by, scrubbing the fermenter off gas. A part of the wash is drawn into a separate
vessel and is aerated there. This external aeration allows the recovery of carbon dioxide un-
contaminated with air.
2.3.1.3 Yeast Recycling
Chapter II
EIA Report: New Molasses based Distillery project Udagiri Sugar & Power Ltd; Dist. Sangli, Maharashtra
2- 6
The yeast in the fermenter wash is removed as 45 to 55% v/v slurry, and is returned to the fermenter.
This feature ensures that a high yeast cell concentration is achieved and maintained in the fermenter.
Mature active yeast will be recycled so as to reduce the excess consumption of sugar by growing
yeast. Thus, it make available for ethanol production and ensuring high process efficiency.
2.3.1.4 Fermentation Parameters (Typical)
The pH of the fermenter is maintained within 4.0 to 4.8 usually by addition of any acid. The alcohol
concentration is maintained between 7.0 to 8.5 % v/v, unless a highly concentrate effluent is to be
produced. Conversion of sugar to ethanol is instantaneous and the residual sugar concentration is
maintained below 0.2% w/w as glucose. This usually corresponds to a residual reducing substances
concentration of 2.0 to 2.5 % w/w in wash. Weak Wash /Spent wash Recycling (Optional - depends
upon yeast strain)
Recycling of weak wash helps to maintain the desired level of dissolved solids in the fermenter, so
that an adequately high osmotic pressure is achieved. Osmotic pressure and the concentration of
alcohol in the fermenter, together keep off infections and minimize sugar losses. Weak wash recycling
reduces the quantity of effluent spent wash and reduces the process water requirement of the plant.
2.3.2 Pressure Vacuum Distillation
Vacuum distillation system consists of three to four distillation columns namely –
Analyzer column – Operated under vacuum.
Pre rectifier column – Operated under vacuum
Rectifier cum Exhaust Column – Operated under pressure
Fusel oil concentration column may be added to improve quality of alcohol further.
Fermented wash is preheated in fermented wash pre-heater and fed at the top of the analyzer
column, analyzer column is fitted with thermosyphon reboiler. Top vapors of analyzer column are
sent to pre-rectifier column. Rest of the fermented wash flows down and is taken as spent wash from
analyzer column bottom. Pre-rectifier bottom liquid is preheated with spent-lees and fed to rectifier
cum exhaust column.
Low boiling impurities are concentrated in the pre-rectifier column. A top draw is taken out as
impure alcohol from the pre-rectifier column. The bottom of pre-rectifier column is sent to rectifier
feed tank. Rectifier exhaust is operated under pressure and heats analyzer column through reboiler.
Alcohol is enriched towards the top and is drawn out as Rectified spirit (RS). Fuel oil build-up is
avoided in the Rectifier column by withdrawing outside streams of fuel oil. These are sent to fuel oil
concentration column from where the fuel oil is sent to decanter for further separation. The fuel oil
wash water is recycled back to the column. A top draw is taken out as impure alcohol from the top of
fuel oil column & pre-rectifier column.

2.3.2.1 Benefits of Pressure Vacuum Distillation
The technology advantages are as follows.
Since the analyzer column operates under vacuum, the formation of by-products such as
‘acetyl’ may minimize there by improvement in quality of alcohol.
Pre-rectification column ensure removal of unwanted substances and also reduces load of
lower boiling volatile compounds passing on to Rectifier cum exhaust column.
The chances of scaling due to invert solubility of certain precipitating inorganic salts are
minimized in vacuum distillation.
Vacuum distillation requires low steam consumption i.e. 2 Kg/lit. for Recited Spirit and around
3.2 Kg/lit. for export quality ENA.
2.3.2.2 Process of Manufacture of Extra Neutral Alcohol (ENA) and AA
Extra neutral alcohol is manufactured from rectified spirit. The impurities in rectified spirit are
reduced to considerable extent by properly diluting and redistilling the spirit. The impurities like
aldehydes, acids, esters, higher alcohol's are minimized by controlled condition and tapping
impurities at appropriate points during distillation.
The main stages in the manufacture of extra neutral alcohol are -dilution of rectified spirit with
filtered soft water in the ratio 1:3 to 1:4.The diluted spirit may be treated with potassium
permanganate. Separation of low boiling impurities takes place in purifying column, separation of
esters and other volatile impurities in Rectifying column and concentration of alcohol. Removal of
excess water takes place at exhaust column. Concentration of fuel oil & their removal takes place in
the fuel oil concentration column. Concentration of low boiling impurities & their removal takes place
in the head concentration column.
Fuel ethanol is an important product required by industry. As per IS specification it is nearly 100%
pure or water free alcohol. In order to extract water from alcohol it is necessary to use some
dehydrant or entrainer, which is capable of separating, water from alcohol. The various processes
used for dehydration of alcohol are as follows
I) Azeotropic Distillation
II) Molecular Sieve Dehydration (MSDH)
III) Pervaporation / Vapour permeation system.
From these, the USPL has planned to select molecular sieve dehydration (MSDH) technology.

2.4.1 Land
The proposed distillery unit will be within the existing sugar mill premises, which is located at village
Bamani (Pare), Khanapur tahsil of Sangli district. The sugar mill is having total 72 acres of land, out
of which approx 35 acres of land is utilized by sugar mill and its ancillary units. From the remaining
land 10.5 acres will be utilized for distillery, its ancillary units including greenbelt. Surplus land is kept
reserved for future developments.

2.4.2 Raw material: Molasses
The total quantity of molasses required per annum is around 32,400 MT. While estimating the
requirement fermentable sugar of 45-47% was considered; this usually yields about 280L of spirit per
MT of molasses. The mill has estimated a molasses production of 27,000 MT for the season of 2014-
15 (refer table 2.5- These estimates are based on the cane development programme of the mill, sugar
mill modernization planned by the management to achieve higher efficiency and existing cane
availability. Remaining quantity of molasses of about 5,400 MT will be procured from nearby sugar
mills. There are 18 sugar mills in Sangli district, of which only 7-8 factories are having distilleries. In
the adjacent district Kolhapur, there are 22 factories of which 10-11 are having distilleries. This
indicates, the distillery could get the deficit molasses from the nearby sugar mills.
Storage: At present, the mill has one mild steel tank of 7,000 MT capacity. The mill has decided to
install one more MS tank of 10,000MT capacity. Thus, capacity of molasses storage will be 17,000MT.

2.4.3 Steam
The steam requirement of the proposed distillery will vary from 5.5 to 6.5 MT/h depending on the
final product (for Multi-pressure option). This requirement will be fulfilled from sugar mill boiler. At
present the mill is having one Bagasse fired boiler of 75 TPH operated at 72.5kg/cm2 pressure and
515oC temp. Presently it consumes approx 30TPH of bagasse and supplies steam to cogeneration
unit. Exhaust low pressure steam from the turbine is used in sugar unit. Now, additionally it will be
used for distillery operations. The estimated fuel requirement for distillery is 2.29TPH, however, no
additional fuel will be required for the distillery during season. The same boiler will be operated at
lower capacity to fulfill the requirement of cogeneration and distillery unit during off-season of sugar
mill.

2.5 EFFLUENT TREATMENT
2.5.1 Spentwash
2.5.1.1 Primary Treatment: Bio-methanation
In recent years, due to escalation of energy costs and environmental concerns there is an increase in
the installation of anaerobic treatment units for distillery-spent wash. The anaerobic method of
spentwash treatment offers number of significant advantages with some drawbacks over other
treatment methods.
Benefits Limitations
Production of methane as a fuel, it is renewable
source of energy and helps in reducing direct
emission of methane into atmosphere
It contains sulfur in minor quantity (less
than 2%), which causes damage to boiler;
act as a source for SOx emissions
Low production of waste biological solids Relatively long periods of time are required
to start up the process
Low nutrient and power requirement It is a pre-treatment method. Hence,
some of the parameters such as BOD,
COD, colour, TDS, etc. requires adequate
treatment for its safe disposal.
Very high loading rates can be achieved -----------
Active-anaerobic sludge can be preserved unified for
many months

The biochemistry and microbiology of anaerobic processes is much more complicated than that of
aerobic ones. As a result many pathways are available for an anaerobic process. These pathways and
microorganisms responsible for the reactions are not known in great detail but during the last 10-15
years a broad outline of the processes have been established.
2.5.1.2 Microbiology & Biochemistry Of Biomethanation Process
Basically the anaerobic degradation is performed by two groups of bacteria.
Acid producing bacteria : Acid forming bacteria (butyric & propionic acid) Acetogenic bacteria
(acetic acid & hydrogen)
1) Methane producing bacteria : Acetoacetic methane bacteria (acetophilic) Methane bacteria
(hydrogenophilic)
2.5.1.3 Steps of Reaction
The anaerobic metabolism of a complex substrate, including suspended organic matter, can be
regarded in a three-step process
Step I: Hydrolysis of suspended and soluble organic of high molecular weight
Step II: Degradation of small organic molecules to various volatile fatty acids, ultimately acetic
acid.
Step III: Production of methane, primarily from acetic acid, also from hydrogen and carbon
dioxide
Out of three steps, the second one is rather quick, while the two others are slow. This accounts for
many instability problems encountered in anaerobic processes. However, the anaerobic processes
are not more unstable than aerobic. One of the reasons why this is a rather rare view is that
engineering design practice for anaerobic processes through the years have been operating with
rather small safety factors and a very poor process control.
Hydrolysis of organic matter is a rather slow process brought about by extra cellular enzymes. Factors
like pH and cell residence time play an important role with respect to reaction rate.
During start-up of the anaerobic process the volatile acid concentration should be kept reasonably
low (1-1.5 Kg HAC/m3) and can be used to control the slow loading. The hydrogen partial pressure (or
redox potential) regulates the production of the various acids. For digesters, operating at very short
solids retention time the concentration of propionic acid and hydrogen is increased. This fits well into
the general picture, and can also explain the increased propionic acid concentrations under unsteady
state or varying load conditions. Propionic acid is an indicator of instability and has been generally
accepted as a process control parameter all though not used much in practice.
If, the acid production rate is high as compared to the methane production rate, which means that a
sudden increase in easily degradable (soluble) organic will result in increased acid production with
Chapter II
EIA Report: New Molasses based Distillery project Udagiri Sugar & Power Ltd; Dist. Sangli, Maharashtra
2- 18
subsequent accumulation of the acids. This might inhibit the next step of the process the methane
generation step. Parallel to the acid production ammonia is released by the degradation of proteins
and amino acids. The ammonia concentrations thus established would generally not be of a
magnitude that will inhibit the anaerobic process but nitrogen rich wastes, treated in highly loaded
processes, ammonia inhibition could occur.
Methane production is a slow process, in general the rate-limiting step of anaerobic degradation.
Methane is produced from acetic acid or from hydrogen and carbon dioxide. About one third of the
methane has its origin in molecular hydrogen. Small amounts of methane can be produced from
methane and formic acid, but these reactions have little practical importance. The bacteria producing
methane from hydrogen and carbon dioxide are fast growing ones as compared with the acetic acid
utilizing bacteria.
2.5.1.4 Utilization of Biogas
Biogas generated in the bio-methanation process will be utilized as a fuel for Mill boiler. Flare unit will
be installed as an alternative, in case of non-consumption of biogas in boiler. There are some
alternative available for the use of biogas. It can be upgraded /purified into methane and
compressed. This is used for higher commercial applications such as fuel for vehicles or for generation
of electricity. However, considering the investment and other economics, these options could be
useful in near future.
2.5.1.5 Bio-Composting
Bio-compost is prepared by mixing spentwash and pressmud (filter cake produced during sugar
manufacturing, having 50-70% moisture) in an optimum proportion of 3:1. The activity is carried out
with the help of excavator- cum –loader for mixing, turning, loading and unloading of compost
material. It is observed that in the first five days, fungal activity is predominant and in subsequent
days bacterial activity continues until stabilization of organic matter into humus is accomplished.
The composting site will accommodate the required number of windrows of filler material. The
windrow size (width & height) will depend upon the type of aeration mixing and turning machine as
well as area of yard to be used. The filler material will comprise of filter cake, screened/half
decomposed bagasse, bagacillo, boiler ash, sludge from biomethanation unit as well as ETP etc. The
windrows will be inoculated with certified microbial culture to enhance the composting process. The
filler material will be homogenised with mixing/turning and aeration machine. The machine traverse
windrows, thoroughly aerating and agitating the composting mixture and grinding shredding of lumps
to uniform size. Spent wash will be sprinkled on windrows in a controlled manner at specific intervals
so as to maintain the moisture content of windrows around 50 to 60 percent. The spraying of the
spent wash will be strictly controlled so as to avoid seepage problem and avoiding anaerobic
Chapter II
EIA Report: New Molasses based Distillery project Udagiri Sugar & Power Ltd; Dist. Sangli, Maharashtra
2- 19
condition. The windrows will reach a temperature of 65-70oC automatically and within a period of a
week followed by a turning. This will now require more spent wash for maintaining the moisture.
The composting cycle will be of minimum six weeks.
2.5.1.5.1 Operational Details
A composting cycle can be divided into two stages i.e. 40 days of windrow composting (Aerobic
process) and 4-5 days for curing in heaps. Thus, one cycle takes about 45 day’s period.
Compost process can be divided into the following stages –
Active Stage
It is a stage when the maturation is just initiated. During this period there is a rise in
temperature, which continues for first 10-15 days of process after formation of windrows and
spraying of inoculum.
Maturation Stage
This stage includes the greater part of maturation and extends to and beyond the period of
temperature decline. It consists of the 14 days when the temperature is maintained and the
next 10 days when the temperature starts to decline.
Ripening or Curing Stage
This stage allows compost to age for four weeks, until the moisture stabilizes at 30% to 35%.
2.5.1.5.2 Windrow
Recommended windrow Size = 3.0 x 1.5 m (Width x Height- subject to available area)
Distance between two windrows = 1m
Press-mud should be formed in windrow size of 3.0 x 1.5m. The windrows should be formed straight
and have correct size.
2.5.1.5.3 Culture Inoculation
After running the machine for a day, spray inoculum. Inoculum acts both as an odor reducing agent
and an activator to hasten the process of raising the temperature. Normally for every MT of press-
mud 0.5kg of inoculum is applied. It is diluted 100 times with effluent and sprayed on the windrows
spreading over 3 days for effective results (in the 3rd, 5th and 10th day) Immediately after the
application of inoculum, windrow should be aerated with mixing machine to spread the Inoculum
uniformly to all parts of windrow.
2.5.1.5.4 Aeration
Normally mixing machine is used for mixing up the windrow, loosen the same and create a situation
congenial for natural aeration. When the moisture content reduces below 50% an addition of effluent
should restore it to 65%. If the press-mud is wet (more than 70% moisture) there is lower supply of
Chapter II
EIA Report: New Molasses based Distillery project Udagiri Sugar & Power Ltd; Dist. Sangli, Maharashtra
2- 20
oxygen. Moisture content should be brought down to about 50% by giving proper aeration.
Microorganisms make use of nitrogen and carbon for their metabolic activities. The energy required
for this process is derived by aerobic decomposition.
Aeration is given to raise the compost temperature and establish aerobic condition. The temperature
should be 60-650C in the windrow. Continue spraying and aeration till the completion of composting
cycle.
2.5.1.5.5 Effluent Spraying
Spraying is done before aeration. The quantity of effluent applied is strictly controlled so that the
windrows always have moisture content, which is optimum for aerobic composting.
2.5.1.5.6 Merging of Windrows
Once the hard material or lumps is broken by the mixing machine and is loosened, it gets compacted
and the windrow height gets reduced due to proper degradation of organic matter with proper
aeration.
After about 15 days of initial composting the windrow height is likely to be reduced to about 0.5
meter. At this point it is required to merge 2 windrows into one and continue further processing.
2.5.1.5.7 Curing in Heaps
After completing the spraying, windrow is aerated for 2 or 3 days without spraying effluent. After
reducing the moisture to about 30% to 35% heap the compost in the corner to a height of about 2
meter to have anaerobic process for about 15 days and also to make the space free for fresh windrow
formation.
A distinctive black loamy, free flowing and ready to use compost, which has a pleasant earthy smell
and moisture content of 30-35 % is produced.
The salient features of Bio-compost process are:
1. Zero Pollution
2. No odour or fly nuisance. The finished product is entirely free from any repulsive odour
3. High product value – quick payback
4. Product is usually dry, easy to handle, bagged and transport

will be involved for fast degradation of BOD and COD values in spent wash surface. The compost site
will be prepared as per the norms specified by Central Pollution Control Board (CPCB), New Delhi. The
details of which are furnished in the chapter Environment Management Plan.
A separate Environmental cell will be constituted and it will monitor this entire operation. Bore wells
will be set up towards the downstream side of the compost site to check the seepage; if any. The
results shall be recorded for the perusal of the regulatory authorities.
The schematic indicating the tentative layout for complete composting process including storage
tanks, windrows, and chamber is shown in Fig. 2.5.

2.5.2.2.1 Anaerobic Filter
The anaerobic filter, also known as fixed bed or fixed film reactor is used for the treatment of non-
settelable and dissolved solids by bringing them in close contact with a surplus of active bacterial
mass. This surplus together with “hungry” bacteria digests the dispersed or dissolved organic matter
within short retention times. Anaerobic filters are reactors consisting of supporting material layers.
On the surface of these material layers or bed, fixation of microorganism and the development of
biofilm take place. Anaerobic filters can be applied not only for treating concentrated wastewater but
also for those wastewaters that have low organic load (grey water). If they are preceded by a reactor
that retains settled solids, they will work better. It is suitable for all industrial wastewater which have
a lower content of suspended solids. The bacteria in the filter are immobile and generally attach
themselves to solid particles or to the reactor walls. Filter materials like rocks, cinder, plastic, or
gravel provide additional surface area for bacteria to settle. Thus, the fresh wastewater is forced to
come into contact with active bacteria intensively. The larger surface area for the bacterial growth
helps in the quick digestion of the wastes. A good filter material provides a surface area of 90 to 300
m2 per meter cube reactor volume. Biological oxygen demand up to 70% to 90 % is removed in a well
operated anaerobic filter.
Pre-treatment in settlers or septic tanks may be necessary to eliminate solids of larger size before
they are allowed to enter the filter. When the bacterial film becomes too thick it has to be removed.
This may be done by back-flush of wastewater or by removing the filter mass for cleaning outside the
reactor. Nonetheless, the anaerobic filter is very reliable and robust. Anaerobic filters may be
operated as down flow or up flow systems. A combination of up-flow and down-flow chambers is also
possible.
2.5.2.2.2 Biological (Aerobic) Treatment
This is the main section of the plant where degradation of organic pollutants with the help of aerobic
micro-organism takes place.
In aeration tank activated biomass is developed in such a way that certain MLSS is maintained for
continuous condensate flow which comes to aeration basin. Condensate is degraded in given
retention time and activated sludge is further passed to clarifier and recycled as per requirement.
The sludge, which is not required after recirculation, is passed to sludge drying bed
To maintain the aerobic condition in the bioreactor, air supply arrangement is provided by means of
aeration equipment which has high oxygen transfer efficiency.
2.5.2.2.3 Secondary Clarifier
Chapter II
EIA Report: New Molasses based Distillery project Udagiri Sugar & Power Ltd; Dist. Sangli, Maharashtra
2- 27
In secondary clarifier, condensate passed from aeration tank along with biomass (MLSS) gets settled
here. The settled biomass recycled back to aeration tank as per requirement and excess biomass
transfer to sludge drying bed.
2.5.2.2.4 Disinfection
Supernatant from Tube settler, flow by gravity to the chlorine contact tank. To disinfect the harmful
bacteria in the treated water as well as to remove the refractory organics from treated water, in this
tank hypo chlorite solution is dosed with the help of dosing system.
2.5.2.2.5 Sludge disposal system
Settled sludge from tube settler will be removed by pumping to the sludge drying bed.
2.5.2.3 Tertiary treatment:
Secondary treated water will be further passed through sand media filter followed by activated
carbon filter.
Filtered water will be collected in the Treated water Storage tank from where it will be for desired
non potable application. Backwashed water from filters will return back to equalization tank.
2.5.3 Advantages of treatment scheme
a. It will produce the treated water which can be recycled back, thus, very important to save
freshwater intake
b. It is based on biological principle hence no need use of any excessive
hazardous chemicals for the main degradation process
c. Due to efficient aeration system, electrical power requirement will be very low
d. Due to user friendly equipment, plant maintenance will be very less.
e. Due to inbuilt automation, plant machinery life is high & ensures trouble free operation
f. All process rotating electromechanical equipment is provided with standby equipment to
ensure the uninterrupted operation.

2.6 GREEN-BELT DEVELOPMENT
Usually, a greenbelt is developed with an objective of attenuation or mitigation of pollution.
However, the importance of the greenbelt should not confined for pollution control because it offers
many other advantages such as -
Create an aesthetic
Helps to enhance bio-diversity to some extent and thus supports ecosystem
Controls temperature
Maintains micro-climatic conditions
Helps to hold water and restore ground water
Prevent soil erosion & surface run off
The sugar Mill has developed a greenbelt present around the fencing of the premises. It has also
developed greenbelt around guest house and small housing colony near the Mill. Details of existing
greenbelt are mentioned in table 2.18. In case of the proposed activity, greenbelt developed around
manufacturing unit will consist of tall and medium size trees. These trees will be developed in 2-3 raw
curtain, depending upon space availability. Ornamental shrubs, herbs including lawn will be
developed at selective locations.
Greenbelt will also be developed around the waste disposal areas, such as ETP, compost yard,
spentwash storage lagoon, etc. This will be mainly for beautification. Since, the soil around industry is
combination of clay and loam, water holding capacity of the same is around 50%, which is significant.
This factor is considered while estimating the water requirement, which is around 52m3per day.
Treated effluent from sugar Mill will be used for watering plants. While suggesting species for
greenbelt developments following factors are predominantly considered.
Climatic conditions such as rainfall, temperature, humidity, etc.

BASELINE ENVIRONMENTAL STATUS
3.1 INTRODUCTION
The baseline environmental conditions are established through field studies/monitoring (primary
data) and secondary data such as reports and survey records published by authentic agencies.
Considering the site at the centre, a 10km radius area was defined as a study zone. In the study
zone, primary and secondary data was collected. In addition, information on the location of
towns and cities, national parks, wildlife sanctuaries and ecologically sensitive areas, etc. was
collected. Guiding factors for the baseline study of the project are terms of references (ToR)
issued by Ministry of Environment and Forestry (MoEF) and the Environmental Impact
Assessment notification Sep. 2006. For the present study, the field monitoring was carried out in
summer season of 2014 i.e. March to May 2014. Data was sufficient to develop a clear
understanding of the nature and magnitude of potential impacts of the project. Generally, the
baseline environmental study is carried out by collecting data on attributes such as air, noise,
water, soil, flora, fauna and overall ecosystems. In addition, data for meteorology, topography
and drainage, hydrology, geology, socio-economy together form an appropriate baseline data. All
these elements together describe the prevailing conditions and facts about local environment.
This helps in understanding the environmental characteristics of the area and thus, assessing the
impact on existing environmental quality, on the basis of proposed developments being planned.

3.3.1 Climate and Rainfall
Agro Climatic Zone (NARP): Western Maharashtra Scarcity Zone (MH-6); and Western
Maharashtra Plain Zone (MH-4).
Sangli has a semi-arid climate with three seasons, a hot, dry summer from the middle of February
to the middle of June, a monsoon from the middle of June to late October and a mild cool season
from early November to early February. The climate in the district is fairly tolerable throughout
the year. The climate gets hotter and drier towards the east and humidity goes on increasing
towards the west. The maximum temperature ranges between 31.5o C and 38.2oC, while the
minimum temperature ranges from 12.9oC to 22.7oC.
This district falls partly in Krishna basin and partly in Bhima basin. Consequently, it is divided into
different drainage systems. The whole district can be divided into three different parts on the
basis of topography, climatology and rainfall viz.
1. Western hilly area of Shirala tahsil with heavy rainfall.
2. The basin area of Krishna, Warna & Yerala rivers, comprising of tahsil Walwa, & western
part of Tasgaon and Miraj tahsils with medium rainfall.
3. Eastern drought prone area which comprises of eastern part of Miraj, and Tasgaon
tahsils, north-eastern part of Khanapur tahsil and whole of Atpadi, Kavathe Mahankal &
Jath tahsils.
Chapter III
EIA Report: New Molasses based Distillery project
Udagiri Sugar & Power Ltd; Dist. Sangli Maharashtra

The western part of Shirala tahsil gets heavy rainfall on an average over 1300 mm in a year.
The central and eastern parts receive annual rainfall about 900 mm in a year. The
northeastern portion receives the lowest rainfall in the district - only 300 mm in a year. Due
to this lowest rainfall, the tahsils of Atpadi, Jath, Kavathe Mahankal, Miraj (East), Tasgaon
(East) and Khanapur (East) are drought prone areas.

some relief from the heat on few days. The onset of the south-west monsoon by the first or
second week of June brings down the day temperatures appreciably, but night temperatures
continue to be nearly the same as in summer. During the south-west monsoon, the weather is
cool and pleasant. Sometimes the day temperatures are even less than in the cold season.
After the withdrawal of the south-west monsoon by the end of September, day temperatures
increase slightly. After about mid-November both day and night temperatures begin to drop.

PC based GIS and image-processing software was used for the purpose of image classification and
for delineating drainage and other features in the study area. Number of peripheral devices such
as scanner, plotter, printer etc. has also been interfaced with the system. Satellite data of Rabi
season was classified using supervised classification technique. Maximum likelihood algorithm
classifier was used for the analysis. The scenes were individually classified and then were
integrated to get a composite classified output where information from Rabi season is available.
A truth table was generated taking 0.95 as the conversion threshold. After aggregation, the final
classified output was converted in raster format. The image was then converted in raster format,
which is understood by GIS software. Eight landuse/ landcover classes were identified in ten sq.
km area around the Project Site. Area under each class has been calculated (Table 3.8).

3.3.7.1 Contour
Contouring is the standard method of representing relief on topographic maps. Contour lines are
lines joining points of equal elevation on the surface of the ground. They can also be thought of
as the lines of intersection between a series of horizontal planes and the ground surface. For a
given map the vertical distance between adjacent contour lines or the contour interval is fixed
i.e.20m. By examining the horizontal distance between successive contours it is possible to
visually estimate the variation in slope of parts of the terrain. As the vertical distance between

maximum height of the terrain in given study area of10 sq.km is 890m at a distance of 10km
towards northeast of the site. It can be easily found that a range is passing from northern part to
southeastern part of the study area,
3.3.8 Soil
Soil formation in Sangli district has been predominantly influenced by the climate. Soil is different
in different parts of the district. The western zone, which receives very heavy rainfall, has lateritic
soils on up-ghats and reddish brown soil on hill slopes, the latter being developed on parent
material of trap rock. It is 7.37% of the total area of the district. The transition zone of Krishna
valley has deep black soils of alluvial origin. It is observed in central part i.e. Entire Walwa tahsil
and western part of Miraj and Tasgaon tahsils. It is 26.18% of the total area of the district. The
third is the eastern drier zone, which consists largely of regular black soils and poor shallow soils.
Saline-alkaline soils are met with in the low-lying patches in the areas of low rainfall. The soil is
faint gray accounting for 66.45% of the total area of the district. Land in the region is best
suitable for agriculture.

3.3.9 Geology
The basaltic lava flows belonging to the Deccan traps of upper cretaceous to Eocene age is the
only geological formation occurring in Sangli district. Isolated patches of laterite are occurring
along the eastern boundary. The Deccan traps are overlain by alluvial deposit at few places along
the Krishna and Warna river. The stratigraphical sequence of various geological formations
occurring in the district is given below.
Formation Age Lithology
Alluvium Recent Sand silt and clay
Laterite Pleistocene Laterites
Deccan Traps Eocene to Upper Cretaceous
Basaltic lava flows of amygdular and massive nature flows often separated by red bole.
The Deccan Traps are formed of effusive lava flows. These basaltic rocks are fine grained with
gray to black in colour. They overlie the rocks of granitic composition with extremely irregular
contact zones. They are formed of a number of lava flows towards the close of cretaceous.
Subsequent to the bagh and lamet beds a large part of the Indian peninsula and entire study
region was affected by an outburst of volcanic activity. It resulted in the eruption of lava flows
and associated pyroclastic materials. These, some hundreds of meters of horizontally bedded
sheets of basalt have resulted. The thickness of these beds decreases towards east. The beds

obliterated all the previously existing topographical details and it gave rise to an immense
volcanic plateau. Basalt and laterite are two main types of rocks in the study area. The individual
geological formations are described below in detail.
3.3.9.1 Deccan Traps
The Deccan Traps are formed by piling of basaltic lava flows over one another. The individual flow
has two distinct units. The upper layer generally consists of vesicular basalt. Vesicles are often
filled by secondary minerals like zeolites, quartz, and calcite and hence called as zeolitic traps.
The bottom layer consists of hard and compact massive basalt. The flows are usually separated
by thick red clay compact massive basalt or called as "Red Bole". The thickness of flow varies
from few meters to as much as 30 meters
3.3.9.2 Laterite
Laterite caps over plateau tops have been observe along the eastern border of the district. The
occurrence of laterite caps is of sporadic nature and does not have wide extension.
3.3.9.3 Alluvium
The river Krishna and Warna have deposited alluvium along the banks at few places. The alluvium
consists of clay, slit and sand. The alluvium occurs in small patches and does not have a
continuous stretch. It is underlain by the Deccan Traps. The thickness of alluvium is very
insignificant and ranges between 6 to 10 meters.
3.3.9.4 Lineaments
The presence of weaker zone i.e. fractures in the basaltic rock have been observed on the
satellite imagery in the form of lineaments. Most of the lineaments are trending in northwest-
southeast and northeast-southwest direction. The lineaments at places have controlled the
drainage's.

3.3.10 Geomorphology
The Sangli district is dominated by the trappean land forms. The trappean land forms of the
district have been divided in two groups depending upon origin of the land forms viz., the
structural land forms and denudational land forms. The structural land forms again have been
divided in two units depending upon the degree of dissections namely, 1) Highly dissected
plateau (HDP) and 2) Moderately dissected plateau (MDP). A very small area along the major
rivers shows the fluvial land forms. Various land forms have been identified and delineated by
studying the image characters, which are described below in detail.
3.3.10.1 Fluvial Origin
Valley Fill: A very small area along river Krishna and Warna is covered by alluvium which forms
the valley fill. The area has a gentle slope, thick soil cover as well as covered by sand, silt and clay.
The area forms the storage zone. Agriculture is the principal land use of the area.
3.3.10.2 Structural Origin
Highly Dissected Plateau (HDP): The district is located at the foothills of steep sloping western
ghat hill range. Therefore, major part of the district is exposed with hard and compact basaltic
flows which also has a moderate to steep slope. These areas have been classified as the highly
dissected plateau. The area has a very high drainage density and thin soil cover and therefore

forms the run-off zone. Major parts of Shirala, Khanapur, Tasgaon, Atpadi, Miraj, Kavthe-
Mahankal and Jath tahsils are occupied by the highly dissected plateau. The highly dissected
plateau units are dominated by the scrub lands.
Moderately Dissected Plateau (MDP): The low lying valley areas which has a moderate slope form
the moderately dissected plateau ( MDP). These plateau units are also covered by the basaltic
lava flows. The area has a moderate drainage density

3.3.11 Hydrology
3.3.11.1 Rivers and dams
• Krishna with tributaries Warna and Yerla flows through the western part of the district.
• Warna flows from west to east along the southern boundary of the district and joins the
Krishna at Haripur near Sangli town.
• Yerla flows from north-west to south-east and after traversing the western parts of
Khanapur and Tasgaon tahsils joins Krishna near Brahmanal
• These rivers are the lifelines of the western half of the district and serve as source for
large irrigation schemes.
• Agrani, Man and Bor constitute the drainage system for the eastern part of the district.
The water resources from these rivers are limited and they remain dry for most part of
the year.

• There is only one major dam at Chandoli on the river Warna. Besides, there are two major lift
irrigation schemes on the Krishna River. There are five Medium Irrigation Projects, namely
Morna, Shindewadi, Bassappawadi, Doddanala and Sankh. There are 66 minor irrigation projects,
462 percolation tanks 353 masonry dams and 11 Kolhapur type weirs (Bandharas).

the water quality in 10km radius area was partly deteriorated but acceptable for domestic
activities.
3.3.12 Air environment
The ambient air quality status was monitored in the study area of the site. Baseline values of the
same were used to calculate incremental air pollution load with respect to monitored locations.
Thus, it helped in predicting the impacts due to the proposed activity on the air environment of
the study area.
3.3.12.1 Methodology of monitoring
The ambient air quality monitoring has been conducted during the months of March to May 2014
(summer season). Monitoring has been conducted twice a week, for 24 hours at one location.
The fine dust sampler of Polltech Make were used to collect air samples for PM10, Pm 2.5, SOx
and NOx. There were four stations installed in the factory premises and six stations were in the
surrounding villages, including prevailing upwind and downwind directions. The monitoring
locations are shown in figure 3.11.

3.3.12.2 Observations
The observations for PM 10, PM 2.5, SO2 and NO2 were well within new National Ambient Air Quality
(NAAQ) Standards (November 2009). Predominant wind direction during monitoring period was west,
southwest. Padali village at a distance of 2.km is in downwind direction and influenced by the sugar mill
air pollutants. Village Narsewadi is another residential area located towards east of the factory at a
distance of 4.5km. This is located on a small hillock of 17-20m in height. The concentrations of measured
parameters (i.e. PM, SOx, NOx) were significantly less compared to village Padali. There are two sugar
mills in 20km radious area of the factory; namely Yashwant Sahakari Sakhar Karkhana Limited towards
north west at approx 16km from the site and Tasgaon Sahakari Sakhar Karkhana Limited towards
southwest at 17km from the site. Cane transportation and crushing operations of these factories might
have some influence on ambient air quality of the study zone. The other influencing factors for ambient
air quality of study zone were agricultural activities in the surrounding area, domestic activities,
vehicular movements, etc.
3.3.13 Noise environment
Noise in general, is sound which is composed of many frequency components of various loudness,
distributed over the audible frequency range or Noise can be defined as an unwanted sound. It
interferes with speech and hearing. If intense enough, it can damage hearing, or is otherwise annoying.
The definition of noise as unwanted sound implies that it has an adverse effect on human beings and
their environment. Noise can also disturb natural wildlife and ecological system.
The most common and universally accepted scale for noise measurement is the weighted scale which is
termed as dB. This is more suitable for audible range of 20- 20,000 Hz and has been designed to weigh
various components of noise according to the response of a human ear. The environmental impact
assessment of a noise from the industrial activity, vehicular traffic can be undertaken by taking into
consideration various factors like potential damage to hearing, physiological responses, annoyance and
general community responses which have several effects varying from rise Noise Induced Hearing Loss
(NIHL) etc.
Noise levels were measured using a sound level meter. Noise survey has been conducted in the study area
to assess the background noise levels in different zones viz. residential, and Industrial zones. Noise
samples were collected from four locations within factory premises and eight locations in the surrounding
study zone.

Figure 3.12: Noise monitoring locations
3.3.13.1 Method of Monitoring
Sound pressure level (SPL) measurements were undertaken at above locations, for a period of 10
seconds, at an interval of 30 minutes per hour for 24 hours. The day noise level has been monitored for
6 am to 10 pm and night levels during 10pm to 6am at all monitored locations. The results of the noise
monitoring at the places monitored are given in Table 3.11
A reconnaissance survey was undertaken to identify the major noise generating sources in the area. The
different sources of noise were identified - mainly from industrial activities, commercial activities at very
minor scale, traffic, etc. The noise monitoring has been conducted at all the identified location in the
study area during the study period. Measured noise levels, displayed, as a function of time, is useful for
describing the acoustical climate of the community. Noise levels recorded at each station with a time
interval of about 30 minutes are computed for equivalent noise levels. Equivalent noise level is a single
number descriptor for describing time varying noise levels. The equivalent noise level is defined
mathematically as

3.3.13.2 Observations
Noise levels within factory premises were observed within national standards for industrial zone. Day
time noise levels were observed exceeding the standard (55dB(A) level at village Padali, Pare, and
Narsewadi mainly due to agricultural and domestic activities. At village Aalte the noise levels were
measured for the traffic, where average levels observed to be exceeded for day time.
3.3.14 Ecology And Biodiversity
The study area is having semi-arid climatic conditions, where grassland vegetation (ecosystems) with
sparse trees is very common. But, due to human development, it is largely converted into agricultural/
cultivated land. Aquatic ecosystems were observed in the form of small artificial tanks, ponds, etc.
Rivers flows only in rainy season. Sagareshwar wild life sanctuary, having area of 10.87 sq.km is the
nearest sanctuary to the site. It is located at approx 26km from the site towards southwest.
3.3.14.1 Vegetation
Vegetation in the surrounding 10km radius zone was predominantly cultivated one. The crops observed
in the study zone are enlisted in table 3.12 (B). In case of natural vegetation, the site is located in
Khanapur Taluka of the district, which is towards east. Theses Eastern Taluka of the district such as
Atpadi, Jath, Kavathe Mahankal, Miraj (East), Tasgaon (East) and Khanapur are low rainfall areas hence
drought prone. The study area of the project is also part of this low rainfall zone. Hence, the natural
vegetation observed in the study zone is matching with semi arid climate, grasses are dominant with
scrubby vegetation. Species such as Acacia, Tamarind, Neem, Kashid, Subabool, Gulmolhar, Anjan,
Nilgiri, Australian Acacia, Pangara, Chilar, Sisoo, Agave, Khair, Karnaj, Shiras, Char, Bahava, Dhavada,
were very commonly observed. Plantation of Gliricidia under social forestry was observed very
frequently. Some of these were grown naturally where as fewer introduced one. Generally, small hill
slopes are covered with grasses.
3.3.14.2 Fauna
There are no major wild fauna observed in the study zone. Amongst these wild hare, snakes, squirrels
and different types of birds, which commonly observed on Deccan plateau, were recorded from the
area.
No any red listed floral or faunal element was recorded from the study area.

pesticides and also as a market centers for the agricultural productions. Majority of farmers takes animal
husbandry as an occupation, supplementary to farming. Rearing goats and sheep, Poultry are other
important occupations observed in the district. The mining activity is also observed where resources are
available in the district for extraction of stones, grits and bauxite. The sand from river bed is also used
for construction. Some people are working in mining occupation. As Sangli district is endowed with
various river beds and many water storage tanks, dams, due to these resources some people are
working in fishing occupation.
The role of sugar factories through co-operative and private sector is much important in the
development of industrial sector. Additionally, separate industrial estates are developed at Miraj,
Kupwad, Palus, Vita, Jat and Kadegaon, through Maharashtra Industrial Development Corporation.
Besides those the dairy farms, chilling plants and hatcheries, spinning mills are also among growing
industries. These Industrial developments are providing secondary occupation to the locals.
3.3.15.3 Agriculture and Cropping Pattern in the District
Net cultivated area is 594,623 hectares, while double crops area is 59,743 hectares. Thus gross cropped
area is 654,366 Hectares . Net cropped area is 82% as compared to the total cultivable area. Major crops
include Paddy, Jowar, Bajra, Groundnut, Wheat, Gram, sugarcane, Soybean, Grapes, turmeric,
Pomegranate, and Ber.
Out of the net cultivable area, 46% is under Jowar and 16% under Bajra. Jowar (Kharif) is sown in Walwa,
Miraj, Tasgaon, tahsils while Jowar (Rabi) is taken in Miraj (east), Khanapur, Atpadi, Jath and Kavathe
Mahankal tahsils. Bajra is grown in Jath, Atpadi and Kavathe Mahankal tahsils. Paddy is taken in Shirala
and Walwa tahsils. Sugarcane is taken in all the tahsils where there is assured source of water. Grapes
are cultivated in Tasgaon, Khanapur and Kavathe Mahankal tahsils. Tasgaon grapes are famous in India
and the Middle East. Pomegranates and Ber are taken in Jath and Atpadi tahsils while Soyabean is
cultivated in Walwa, Miraj, Tasgaon and Khanapur Tahsils. These tahsils also have groundnut crop.

CHAPTER IV
ENVIRONMENTAL IMPACT ASSESSMENT
4.1 INTRODUCTION
This chapter discusses anticipated environmental impacts based on the quantities and/or
characteristics of various pollutants/ causing factors likely to be generated from different
activities of the proposed project.
4.1.1 Facts and Considerations
The impact assessment is based on following facts and considerations
The sugar unit is already operational
Effective utilization of land, boiler, steam, fuel, molasses, pressmud will be
achieved by the proposed distillery unit
Saving of resources such as bagasse and water
Sufficient land is available with project proponent to accommodate the process
units pollution control units as well as for development of greenbelt; therefore no
alternative site search was undertaken
No rehabilitation/restoration issues involved with proposed site
Land is already used for industrial purpose and no new land use will be set due to
the project
The process is simple and straight
Technology for the process as well as for the pollution control/disposal are
available indigenously
Spent wash treatment and disposal through bio-methanation followed by multi-
effect evaporation followed by biocomposting methods. ZLD will be achieved
The factory is having adequate provision of funds for the project as well as
implementation of EMP
Management is keenly concerned about health, safety and environmental issues
and implement all schemes /measures necessary for it
Project proponents are local, understands the socio-economy of the region and
well aware of environmental concerns of the people
4.2 AIR ENVIRONMENT
4.2.1 Pollution sources
4.2.1.1 Construction activity: Various construction activities of the project such as
erecting various units, buildings, pollution control devices, internal road involve use of
Chapter IV
EIA Report: New Molasses based Distillery project Udagiri Sugar & Power Ltd; Dist. Sangli Maharashtra
4-48
construction equipments, road rollers, water tankers etc. These activities are machinery
intensive and usually driven by diesel engines. Thus, it resulting in emission of gases,
generation of dust and noise
4.2.1.2 Transportation: These activities causes’ air pollution through vehicular exhaust
emissions, dust from roads and loading unloading of material, etc.
In present case, transportation of raw material will be minimal since major raw material such
as bagasse and molasses will be made available from the sugar factory.
Transportation of finished product i.e. RS/ENA or AA usually takes place in bulk. Considering
gross capacity of storage tanks (600m3x7) 4200m3, it will require about 280 tankers
(considering each tanker of 15m3 capacity). Considering the loading time, availability of
tankers at a time and other practical aspects, it is anticipated that 30-40 tankers will
commute daily from the site. This activity may takes place for two to three weeks. Hence,
this could cause increase in NOx, and particulate matter during the period (particular days)
of transportation. Vehicles of employees and visitors could be a regular source of emissions.
The project is going to provide employment to approx 70 persons, in addition there could be
some contractual or seasonal employees. The project is located in rural area, where people
prefer two wheelers (bicycles, motor cycles, scooters, etc) to commute. Hence, about 90-
95% of such vehicular emissions are anticipated from two wheelers (~50-60 in numbers) and
remaining 5-10% due to passenger cars and other types of vehicles (~5-7 in numbers).
Therefore, transportation activity of the proposed project is anticipated to cause minor
increase in vehicular emissions.
4.2.1.3 Preventive, control and mitigation measures
The dust generated during the construction activity could be suppressed by
Sprinkling of water on dust generating sources
Sprinkling of water while loading/unloading the dust generating material,
wherever feasible
To reduce air and noise emissions, instead of diesel operated, electrically
operated machinery (wherever feasible) to be used
Barricading the dust generating or high noise generating areas
Provision of asphalted roads inside the premises and for approach road upto
state highway
Provision of adequate parking for goods as well as staff vehicles
Engage authorized transport agency for goods transport on the term to use well
maintained vehicles for the activity
Chapter IV
EIA Report: New Molasses based Distillery project Udagiri Sugar & Power Ltd; Dist. Sangli Maharashtra
4-49
While bulk transportation, check the time to fill a tanker and call those many
which could get filled in 2-4 hours, example if one tanker requires about 8-10
minutes than call 12 tankers at a time and call next 12 after one and half to two
hours; this will help to reduce the risks of traffic congestion and minor accidents,
waiting period for vehicles and over all air pollution.
Provide separate entrance and exit lanes/gates for goods as well as employees
vehicles
Strict prohibition on washing/ maintenance of vehicles on site or in parking area
All roads with street light and proper signage at strategic locations
Main gate/s with 24x7 security arrangements
4.2.1.4 Manufacturing process: The manufacturing process is likely to generate two forms
of air pollutants i) is due to burning of fuel to generate steam and ii) from fermentation
process
a. Emissions due to burning of fuel (Bagasse)
In the proposed project, bagasse will be used as a fuel, which is a byproduct of sugar unit.
Bagasse is an excellent source of renewable energy. Conventionally, coal or natural gas is
used as a fuel in many other industries. Both, coal as well as natural gas is a fossil fuels and
non-renewable energy source. Burning of fossil fuels is considered as a one of the prime
Green House Gas (GHG) emission source. Hence, use of renewable energy sources is
encouraged all over the world. Use of biomass energy is encouraged especially in power
generation sector, due to its carbon neutral characteristics. The flue gasses generated due to
it will emit ash, which is the main source of air pollution. The analysis of bagasse is given as
bellow.
Table 4.1: Analysis of bagasse
Parameter Value (in %)
Carbon 40-45
Hydrogen 2-6
Oxygen 40-45
Nitrogen 0.15-0.20
Moisture 50%
Ash content 1.5 - 2.00%
Sulphur <0. 01
Calorific value 2,250 kcal/kg
Chapter IV
EIA Report: New Molasses based Distillery project Udagiri Sugar & Power Ltd; Dist. Sangli Maharashtra
4-50
Bagasse analysis report shows that the elements such as nitrogen and sulfur are present in
trace quantities, i.e. less than 0%. Thus, the generation of sulfur-dioxide (SO2) and oxides of
nitrogen due to combustion of bagasse are anticipated to be very low.
The quantity of ash generated can be calculated as follows
Bagasse required to generate 121MT steam per day
(generally observed bagasse to steam ratio 1:2.2)
= 55 MT/day = 2.29TPH
Ash content = 2.00 %
Total Ash generated = 1.10MT/day
= 0.0458 MT/h = 45.80 Kg/h
For bagasse, fly ash generation is usually 40% of total ash generated. ESP is in place on
existing 75TPH boiler to control particulate matter from flue gases
Bottom ash = 27.48 Kg/h
Fly ash generation = 18.32 Kg/h
Fly ash controlled by ESP (considering 98% efficiency) = 17.953 Kg/h
Fly Ash emission = 0.3664Kg/h
= 0.102 g/sec
Apart from this, trifling fugitive dust emission due to opening and leaks in duct and
manholes and also from ash handling operation at unloading and transfer point are the
minor pollution sources
Sulphur Dioxide (SO2): Another source of air pollution could be the SO2 formed due to
burning of biogas in the sugar factory boiler. The H2S present in the biogas after burning will
release the sulphur that will react with the oxygen present in the air and form SO2 the
reaction will be as follows.
2H2S + 2O2 SO2 + 2H2O + S ------------------ (Equation 1)
2(2+32) + 2(16) (32+32) + 32 + 2(2+16)
68 + 64 64 + 32 + 36
Estimated Biogas production (Considering COD 125,000 mg/liters) = 12,180 m3/day
1.) General composition of biogas produced by using distillery molasses are
Methane (CH4) 64%
Carbon dioxide CO2 34%
Hydrogen sulfide (H2S)Max 02%
Chapter IV
EIA Report: New Molasses based Distillery project Udagiri Sugar & Power Ltd; Dist. Sangli Maharashtra
4-51
Amount of H2S from 12,180m3 Biogas = 243.6 m3/day
(Considering the density of H2S =1.539kg/m3) = 374.90 kg
As per equation I – 68 gm of H2S combustion required 64gm of oxygen i.e. 94% of
total volume.
374.9 x 0.94 = 337.41 kg oxygen required
Since the amount of Oxygen required = amount of SO2 generated
Total SO2 produced = 337.41 kg/day
Thus, SO2 Emission will be 3.90g/second
There are mainly two opportunities for NOx formation.
1. Thermal NOx - The concentration of “thermal NOx” is controlled by the nitrogen and
oxygen molar concentrations and the temperature of combustion. Combustion at
temperatures well below 1,300(C (2,370(F) forms much smaller concentrations of
thermal NOx
2. Fuel NOx - Fuels that contain nitrogen (e.g., coal) create “fuel NOx” that results from
oxidation of the already-ionized nitrogen contained in the fuel.
Emissions of NOx from combustion of fuel are primarily in the form of NO. Theoretically,
Nitric oxide (NO) is generated to the limit of available oxygen (about 200,000 ppm) in air at
temperatures above 1,3000C (2,370(F). At temperatures below 760(C (1,400(F), NO is either
generated in much lower concentrations or not at all. In case of bagasse fired boilers, the
temperature encountered are around 850-10000C, mainly due to high moisture content of
bagasse (~50% moisture). This temperature is much lower for formation of NO, which is
usually formed above 1,3000C. However, as a worst case scenario it is assumed that the NO
formation may take place at 50% rate. Secondly, the bagasse analysis data shows that, the N
percentage is less than 0% which is in the range of 0.10 to 0.20%. Therefore, an average of
0.15% of N content is considered while calculating NO emissions in the present case. Thus,
the second probability of fuel NOx becomes insignificant.
4.2.2 Air Dispersion Modeling
Impact on ambient air quality of the study zone is envisaged due to emissions from the
existing boilers of 75 TPH capacity of sugar mill. This boiler is Bagasse fed, supplied @ ~30TPH.
Steam generated at 72.5kg/cm2 at 5150C is fed to steam turbine generator of 14mw capacity
and the exhaust steam at low pressure is used in sugar mill. The distillery unit is going to use
low pressure exhaust steam from the cogeneration unit of the sugar mill. No additional fuel
will be burnt for steam generation during sugar cane crushing season. Flue gases are
released through 72m tall stack after passing through ESP, which is >98% efficient to trap
Chapter IV

4-52
particulate matter. During the off-season, the fuel requirement for distillery unit will be only
2.3TPH, which is <10% of existing (30TPH). It indicates that, the present ambient air quality
of 10km radious area may not get affected. On this background, the baseline air quality data
presented in chapter III table 3.10, observed at all locations were within NAAQS. However,
to calculate incremental load for PM and SOx it is assumed that, there would be additional
bagasse to be burnt.
Prediction of impact on air environment has been carried out employing mathematical model
based on a steady state Gaussian plume dispersion model designed for multiple point sources
for short term. In the present case, Industrial Source Complex-Short Term [ISCST3] developed
by United States Environmental Protection Agency [USEPA] has been used for simulations from
point sources.

The quantity of ash generated can be calculated as follows
The simulation is made to evaluate PM and SO2 incremental short-term concentrations due
to operation of boiler for proposed activity. In the short-term simulations, the incremental
concentrations were estimated for 10 km radius. Modeling has been done considering
boilers as source and is centre of grid for prediction. Hourly meteorological data recorded at
site for summer season on wind speed, direction and temperature is used as input. For the
site-specific mixing heights CPCB document PROBES/88/2002-2003 is followed.

* The baseline concentration (98th percentile) recorded at village Padali at 2km East of the site
The resultant concentrations of SPM and SO2 after operation of Boilers are within the
prescribed National Ambient Air Quality Standards (NAAQS) for Residential & Rural Areas
4.2.3 Other sources of air pollution
Fugitive dust/particulate matter: Fugitive sources will be mainly, from vehicular movement
and bagasse storage. Bagasse will be transported to distillery through closed conveyers,
hence fugitive dust will be negligible.
Carbon dioxide generated from fermentation process, will be of biological origin, i.e.
liberated from an agro-based waste material. Hence, it is assumed to be neutral for GHG and
therefore a minor source. Along with carbon dioxide, methane will be produced from
biomethanation process of spentwash treatment. This methane (biogas) will be used as a
fuel for boiler in sugar unit.
Odour is anticipated mainly due to storage of spentwash and partly from composting activity
Preventive, control and mitigation measures
Use of Bagasse as a fuel
Round RCC stack with 72m height
ESP to control particulate matter
Green belt of 2.6 acres around the project area
Methane produced from biodigesters will be used as a fuel; flare unit is an alternate
arrangement when it will not be used as fuel
Fermentors will be closed and CO2 scrubbers for fermentation unit
Composting will be done aerobically using machines
Ash slurry as well as bottom ash will be used to mix in compost since bagasse ash is
rich in potash

The construction activity will be for short period; the negative impact will be mainly due to
particulate matter. It will be restricted to the site by adopting above mentioned mitigation
measures. Hence, the resultant impact due to construction is anticipated to be temporary
and minor negative.
Human health: particulate matter from various sources and activities of project may cause
related ailments to persons likely to get exposed, beyond the stipulated NAAQS
Air quality: Air dispersion modeling study shows that, there will be minor/negligible increase
in PM concentration by 0.04micro gram at village Padali located at ~2km towards east of the
site. The resultant ground level concentration (after adding incremental load) anticipated to
be within NAAQS. Minor negative impact is anticipated mainly due to stack gas emissions
and transportation activities of the proposed project;
Ecology and biodiversity: Minor negative impact is anticipated on avi-fauna due to stack gas
temperature (approx 80-90oC), and on flora/plants in close vicinity of the project due to dust
(particulate matter)
4.3 NOISE
The identified chief sources of noise in the proposed project are -
Boiler
Motors and pumps

anticipated on particularly human beings and fauna, along the approach road (3km length)
that connects site with state high way.
4.4 WATER ENVIRONMENT
4.4.1 Waste water sources and characteristics: Following wastewater sources have been identified for the proposed project
Spent wash
Spent lees
Blow down from boiler/cooling tower
Wastewater from washing/cleaning
Condensate water
Sewage
4.4.1.1 Boiler blow down
The water used in boiler contains suspended solids, dissolved solids like Ca-salts, Mg-salts,
Na-salts, Fe-salts etc. These salts get concentrated after generation steam from the original
water volume. These solids have to be expelled from time to time to save the boiler being
covered up by scales.
This water has following characteristics.
BOD - 60 to 70 mg/L
SS - 800 to 1,500 mg/L
TDS - 1,500 to 3,500 mg/L
Temperature - 90 to 100oC
The estimated volume form boiler blow down is 2.5 - 3m3/day. It could be recycled after
cooling.

4.4.1.2 Condensate of MEE
Condensate characteristics would be as follows.
pH 3-4
COD 6,000 mg/lit
BOD 3,000 mg/lit
TDS <1000 mg/lit
Temperature 35-45 °C
This water will be treated in condensate polishing unit. The estimated excess condensate is
255m3/day totally recycle or reuse after treatment.
4.4.1.3 Spentwash
Using a continuous fermentation technology spentwash generation is about 10-12 liters per
lit of alcohol. Due to technology advancement, this volume is also getting reduced to 8L/L of
alcohol. Spentwash is a major pollutant and cause of concern for molasses based distillery. It
is because, spentwash is having high temp, highly acidic nature, and dark brown in colour. It
also contains high percentage of dissolved organic & inorganic matter; hence its BOD and
COD are also considerably high. The general qualitative characteristics of spentwash are
highlighted below.

Spent wash could cause severe pollution of surface and ground water. It could act as a
fertilizer if applied in controlled manner under skilled supervision. But, often applied in
excess that contaminates soil and run off from such field contaminates nearby water bodies.
Therefore, storage and disposal of spentwash considered to be important processes from
environment management perception.
4.4.1.4 Floor Washing
Other wastewater originates from washing of the floor, fermentation, vats and other
equipment. The quantity of floor washing will be about 4m3/day and will be reused for
gardening activity, within factory premises.
4.4.1.5 Spentlees
It is also an important source of pollution. The acidic nature of the spent lees is main cause
of the pollution. It will have a pH in the range of 3 – 4. Quantity of spentlees expected from
the proposed distillery will be approx. 75m3/day. The spentlees will be sent to treatment
unit and reused in the distillery.
4.4.1.6 Sanitary wastewater
In the proposed project, sewage generation will be about 5-6m3/day. It will be disposed by
septic tank and soak pit system.
4.4.1.7 Thermal Pollution
The hot effluents are boiler blow down and cooling tower blow down. The hot water will of
about 45-500C temperature and the quantity will be of 40-45m3/day. This hot water will be
cooled down to normal temperature in cooling pond and then recycled. Hence, there will be
no thermal pollution of any surface water body around the project site.
4.4.2 Preventive, control and mitigation measures
Spentwash of 300 m3/day will first treated in biodigesters to produce biogas from this
organic rich wastewater followed by biodigestion spentwash will be sent to multi effect
evaporation unit to reduce its volume from 300m3 to 120m3
Chapter IV
EIA Report: New Molasses based Distillery project Udagiri Sugar & Power Ltd; Dist. Sangli Maharashtra
4-59
Then it will be sent to biocomposting process where it will be mixed with pressmud (a solid
waste from sugar mill) to produce compost; thus achieving ‘zero liquid discharge’ for this
highly polluted entity.
Spentwash storage lagoons and the compost yard will be constructed as per CREP guidelines
(Refer figure 2.4,2.5 and 2.6 of chapter II and also discussed in chapter VI)
4.4.3 Reuse of water (after proper treatment)
Wastewater due to cleaning and washing, Spentlees and condensate water will be treated in
CPU. This unit will comprised of anaerobic followed by aerobic treatment (discussed in
chapter II – point 2.5.2); treated water of 350m3 per day will be used for dilution of
molasses, cooling tower make up, irrigation, or cleaning activities, etc.
Recycle of water: Blow down water from boiler and cooling tower will be cooled in ponds
and recycled then after
Conservation of water: Rain water harvesting to improve the ground water aquifer and
partly fulfill the requirement during startup
4.4.4 Impact assessment
Water availability: No negative impact since, Irrigation Dept will provide the water allocated
for industrial activities only; reuse, recycle of water will save significant of freshwater intake
Water/aquatic environment: No negative impact on water environment as well as aquatic
ecosystems of the surrounding area due to achieving zero liquid discharge
Air environment: minor negative impact due to odour of spentwash and due to generation
of methane and CO2 from composting process
Soil Environment: Due to impervious lagoons and compost yard probability of soil pollution
due to percolation of spentwash is zero. Hence, no negative impact is anticipated; The
compost prepared from spentwash, pressmud and solid waste filler material will help to
recycle the soil nutrients, thus positive impact is anticipated
Ecology and biodiversity: No negative impact, composting process usually attracts avi fauna
due to availability of micro-organisms as a food
4.5 SOIL ENVIRONMENT
Soil is likely to get affected due to following.
a. During construction of various units, removal of top soil layer which is usually more
fertile
Chapter IV
EIA Report: New Molasses based Distillery project Udagiri Sugar & Power Ltd; Dist. Sangli Maharashtra
4-60
b. Excavation activity – particularly for spentwash storage lagoons and compost yard
c. Construction of various permanent structures/roads at project site
d. Degradation of soil due to construction material (cement, concrete)
e. Disposal of untreated solid (ash, sludge, etc) and/or hazardous waste (spent oil, etc) in
soil
4.5.1 Preventive, control and mitigation measures
Top soil layer of 15-20cm to be kept separate and use for greenbelt
development
Disposal of excavated material safely for construction of spentwash storage
lagoons, compost yard, leveling of roads, etc.
4.5.2 Solid Waste Management
Wastes from a sugar industry include bagasse, molasses, press mud, boiler ash and sludge
from effluent treatment plant.
Waste Material Type Upshot
Ash 1.10MT/day Used as a filler material for bio-compost, final
disposal system for the spentwash i.e. distillery

(wet basis)
mixed with biocompost
4.5.3 Preventive, control and mitigation measures
4.5.3.1 Boiler Ash
Bagasse ash is usually non-hazardous, non-toxic in nature, it is rich in potash. Hence, there
are three alternatives for the disposal of it.
I. Mix it with bio-compost prepared at distillery unit (practiced for spentwash disposal
treatment) as a filler material.
II. Directly sold to farmer as it is as a potash enriching material
III. Sell it to bricks manufacturing unit in the nearby areas.
The factory is planning to use it in the composting process.
4.5.3.2 Sludge from CPU
This sludge is usually bio-degradable, organic and nearly neutral in nature. It doesn’t
contains any toxic or hazardous elements. Therefore, this could be safely disposed by
adding it to bio-compost.
Chapter IV
EIA Report: New Molasses based Distillery project Udagiri Sugar & Power Ltd; Dist. Sangli Maharashtra
4-61
4.5.3.3 Hazardous Waste
The only hazardous waste likely to be generated in the project will be the scrap oil from DG
set. However, the DG set will be used only in case of total power failure i.e. captive as well as
Electricity board power supply failure. Thus, the quantity of used or scrap oil is assumed to
be very minor. This waste oil can be disposed off safely by giving it to authorized hazardous
waste oil dealer. Alternatively, it can be used as a fuel for the boiler along with Bagasse
during startup phase.
4.5.4 Impact Assessment
Soil environment: no negative impact of solid waste; The biocompost produced from
spentwash-pressmud and mixing of degradable solid waste will have positive impact on soil
since organic carbon and soil nutrients are likely get recycled by the process
Ecology and Biodiversity: No negative impact due to solid waste; enhancement in micro-flora
due to compost
Water environment: No negative impact due to solid waste
4.6 ECOLOGY AND BIODIVERSITY
Generally, an impact of industrial activity on ecology and biodiversity is observed due to
following major reasons.
Tree cutting/ removal of vegetation
Habitat destruction
Threat to rare, endangered flora and fauna
Disturbance to wild life
Pollution
In case of proposed project, no tree cutting or habitat destruction is involved. National parks
or sanctuaries or biosphere reserves are not observed in 10km as well as 25km radious of
the site. Rare, endangered species of plants or animals are not recorded from the region.

4.7.1 Impact Assessment
While analyzing the impact on of proposed project on socio-economy, following factors were
considered.
Baseline data showed that the agriculture is primary occupation of the people,
hence employment opportunities revolves around agriculture sector
Chapter IV
EIA Report: New Molasses based Distillery project Udagiri Sugar & Power Ltd; Dist. Sangli Maharashtra
4-63
The project is an agro based industry and extension /vertical integration for sugar
unit
Project will promote efficient utilization of available resources such as molasses,
steam, bagasse, electricity, land and man power up to some extent
Production of alcohol will generate large amount of revenue by way of excise duties
Local administrative institutions will also benefitted by collecting taxes/cess, etc.
Fuel alcohol is very important for the country to save on import of crude oil as well
as foreign exchange, this would have many fold impact on national economy
The sugar factory already had initiated several programmes for the benefit of its
employees as well as local farmers
Therefore, a positive impact is anticipated on the regional economy due to the proposed
project. The project could also help in maintaining and developing the infrastructure
required by the society.
4.8 LAND USE, GEOLOGY AND HYDRO-GEOLOGY /DRAINAGE
4.8.1 Impact assessment
LULC map suggest there is not much impact on LU because the land is coming under barren
class. Therefore, the impact on LU is positive i.e. barren is getting converted into future built
up class which is beneficial for local population.
If we consider drainage map of the study area then we can able to say there could be a
minor impact on drainage, as some first order streams are passing very narrowly along the
project boundary.
No impact is envisaged on geology and hydrogeology of the site due to the project.
4.8.2 Environment management plan
Not to damage the first order drainage steams passing through the project boundary.
Precautions need to be taken to preserve or maintain these streams in their natural form or
need to be considered while landscape development.
4.9 OTHER IMPACT: TRAFFIC
In the project, the transportation activity will take place mainly during the construction
phase. Considering the availability of roads railway station are given in following table which

is getting converted into a four lane, the nominal increase in vehicles during construction
phase may not cause any traffic congestion. During operation phase, the transportation
activity will be in phases hence; the probability of traffic congestion would be very low.

CHAPTER V
ANALYSIS OF ALTERNATIVE TECHNOLOGY
5.1 INTRODUCTION
The technologies for the treatment and safe disposal of spentwash- most polluting element
from distilleries – are discussed in this chapter. Traditionally, the spent wash was used for
irrigation of crops and for composting with press mud from sugar mills as filler material. At
several places in the country, it used to be spread on land in an uncontrolled fashion
resulting in destruction of agricultural land and pollution of ground water. When it was not
possible to use it on land, it was often discharged in surface waters affecting the riparian
rights of other users of the water body.
The new recommendations of CPCB/MoEF imposed a restriction on such utilization, of
spentwash on agricultural land. Therefore, it has become necessary to look for technologies
to reduce the volume and concentrate the spentwash, so that it can be handled effectively
without damaging the environment.

5.2.1 Reboiler
Reboilers are used in distilleries for concentrating raw spentwash and simultaneously
recovering heat and water. Depending upon the input spentwash quality and the reboiler
design, the spentwash volume can be reduced to 75 to 85% of its original volume. When the
spentwash is to be used for composting and the rate of production of spentwash is more
than 10 m3 per KL of alcohol production, in volume through heating and evaporation of
water in a reboiler results in a corresponding increase in the concentration of BOD, COD,
nitrogen and TDS. Further, the efficiency of conversion of organic matter (BOD) to biogas in
the biomethanation step may also decrease when a more concentrated spentwash is
treated.
At present there is no prescribed recommendation regarding the quality of spentwash to be
used for preparation of compost. In order to achieve 'Zero Liquid Discharge', many
distilleries are concentrating their spentwash using reverse osmosis (RO) process also. The
effect of such salt laden spentwash, which also would be containing a higher concentration
of organic matter, on the process of composting and the quality of compost, is not known.
5.2.2 Biomethanation
Biomethanation is now a well-established process. Many types of reactor systems are
commonly used, namely, up or down-flow fixed film reactor, up-flow partly fluidized bed
reactor, commonly known as up-flow anaerobic sludge blanket (UASB) reactor and
continuously stirred tank reactor. Each system may have different variations of reactor
configuration, effluent and sludge recirculation and mixing. One variation employs two-
stage decomposition in two slurry reactors in series.
The bio-methanation reactors when properly designed and operated are capable of treating
spentwash having BOD in the range of 40,000 - 50,000 mg/L with an efficiency of 90% thus
producing an effluent having a BOD in the range of 4,000 - 5,000 mg/L. There is also some
reduction in the TDS content of the spent wash. Sulphate is reduced to hydrogen sulphide,
which escapes with the biogas, and there is a corresponding increase in the carbonate
alkalinity. This in turn results in precipitation of some calcium. The TDS of the spent wash
may decrease to 15,000 - 25,000 mg/L. pH of spentwash, after bio-methanation increase up
to 7 or 8. Some reactor designs may require the raw spent wash to be diluted before it can
be treated. This is particularly when the distillery uses continuous fermentation process for
production of alcohol in which case the COD of raw spent wash may be in the range of
Chapter V
EIA Report: New Molasses based Distillery project Udagiri Sugar & Power Ltd; Dist. Sangli, Maharashtra
5- 3
100,000 to 120,000 mg/L. Central Pollution Control Board has recommended that the
dilution water should not be more than 30% of the original volume of the spent wash.
Depending upon the fuel, which the biogas replaces, (i.e. bagasse, coal or furnace oil) the
cost of the biomethanation reactor is recovered in 2 to 4 years
5.2.3 Reverse Osmosis (RO)
In the past reverse osmosis (RO) has been used commonly as the final step in tertiary
treatment of wastewaters to remove dissolved inorganic solids and some recalcitrant
compounds. It is used to recover good quality of water from grossly polluted wastes. This
has been made possible due to development of new membranes and the membrane module
configuration, which allows easy accessibility for cleaning and replacement of membranes.
In any RO system, the preliminary treatment of wastewater is extremely important.
Adjustment of pH and temperature of the waste, which is compatible with the material of
the membrane, increases the membrane life and prior removal of total suspended solids
(TSS) decreases the rate of membrane fouling. Further, the flux of the dissolved substances
in permeate is lower if it is removed before hand to the possible extent by conventional
methods. It also allows operation of the system at comparatively lower pressure, hence
results in savings in operational and maintenance costs. With a poor quality of the feed
water, the quality of the permeate may be maintained only at the expense of recovery.
Pre-treatment usually comprises pH correction, pressure sand filtration followed by
cartridge filtration. The effluent is then pressurized and passed through RO modules. The
vendor of the RO system usually supplies the pre-treatment units also.
Effluent permeate from the RO plants contains carbon dioxide and sulphides. Its quality
can be improved and stabilized by stripping with compressed air in a packed column to
increase the scope of its utilization. In case there is a premium on the recovery water, the
reject from the RO plant is further treated through a secondary RO system or nano-filtration,
which uses a more 'open textured' membrane. This step produces permeate having 22,000-
25,000 mg/L TDS, 3,500-4,500 mg/L COD and 1,000-1,200 mg/L BOD. The permeate
recovery is 11-14% of the first stage feed.
The operation of the RO plant requires skilled personnel. The spares for regular
maintenance may also not be available in the open market. The Membrane required to be
imported. The fouling could be a problem. Running of the plant therefore should be
entrusted to the supplier to ensure efficient and continuous operation.

5.2.4 Multiple Effect Evaporators
Though evaporation is an established unit operation in chemical engineering practice, its use
for concentration of spentwash is recent. With improvements in design and materials and
the willingness of the alcohol industry to spend more on pollution control equipment, some
distilleries are in the process of installing evaporation and drying plants.
Biomethanated effluent can be input to the multiple effect evaporators. However, both
biomethanated and raw SW can be fed to the evaporators. Steam used in the evaporation
process and the evaporated water from the SW feed form the condensate or the recovered
water. The condensate has a slightly acidic pH and BOD and COD of about 10 and 100 mg/L,
respectively.
The biomethanated feed containing about 4-5% of solids is concentrated to 30-33% solids
content. The concentrated SW can be either used for the preparation of compost or further
dried in a spray dryer to yield a solid powder containing about 4-5% moisture. The calorific
value of the powder is 2500 kcal/kg and it can be burnt for production of steam. The ash
obtained from the combustion of the powder is saleable for its potash content. The dry
powder also has a market value of about Rs.750 / T, as a soil additive rich in organic matter
and potash. The concentrated spentwash after evaporation can also be used directly as an
auxiliary fuel along with other fuel for generation of steam.
From a 300m3/d plant treating biomethanated spentwash about 620 kg/hr effluent powder
is generated, which when burnt yields 127 kg/hr ash.
The ash contains about 21% potash. In case raw spentwash containing 10% solids is
concentrated the yield of effluent powder and ash is 1875 kg/hr and 394 kg/hr, respectively.
5.2.5 Mist Evaporator
As the name implies the mist evaporator creates a mist of small droplets by pumping
spentwash through small diameter nozzles placed around the periphery of a duct through
which air is blown. The unit is placed at the edge of a lagoon and the spentwash is pumped.
The resulting mist forms a trajectory reaching as high as 18 m and going up to 55 m in the
horizontal direction. The large surface area of the mist results in evaporation of water and a
concentrated SW falls back in the lagoon. The rate of evaporation depends on temperature,
humidity and wind speed.
Experience with the mist evaporator in the country is limited. It is in use only at one location
for a distillery of 30 KL/d capacities. The manufacturers of the evaporator claim that for the
Chapter V
EIA Report: New Molasses based Distillery project Udagiri Sugar & Power Ltd; Dist. Sangli, Maharashtra
5- 5
yearly average ambient conditions 2 units, each of 30 KW would be required to evaporate
300 m3/d of spentwash.
The setting up of the unit is easy and requires minimal supervision and maintenance
compared to other concentration methods. However, it will operate with varying efficiency
during the year. In the rainy season or in humid weather, there will be little or no
evaporation and the spentwash will have to be stored. Since, the wind direction is likely to
change a number of times for short periods over a day, there is likelihood of the mist spray
falling outside the lagoon. A more definite comment can be made after the unit is operated
for more time and systematic data regarding the solids balance are available.
The concentrated or thickened spentwash will have to be properly disposed. At present,
composting seems to be a possible alternative.
Table 5.2: Merits and Demerits of Each Alternative
# Technology Merits Demerits
1. Concentration Reduction in volume. Energy generation
after combustion.
Start-up and restart-up is a problem. Scaling problem.

5.3 Treatment alternatives for Condensate Polishing Unit(CPU)
Condensate polishing unit, treats condensate from process/MEE as well as spentlees and
other minor effluents. Following alternatives are available for CPU
i. Conventional aerobic treatment (Extended aeration)
ii. Conventional aerobic treatment followed by membrane technology
iii. Conventional anaerobic treatment followed by membrane technology
iv. RO – MBR Technology
v. Soil biotechnology
5.3.1 Process Description for membrane technology: The proposed system is based on cross-flow membrane filtration technique and is
designed for removal of organic acids from the spent wash distilled stream like evaporation
condensate of a distillery unit. The condensate treated by such system can be reused back in
to the alcohol manufacturing process as cooling water make-up thereby reducing the
requirement of fresh water as well as solving the waste disposal to a great extent. The
system is based on following principle operations.
i) Cooling & Neutralization
ii) Membrane filtration of the neutralized stream to remove volatile acids.
iii) Recycle of treated streams back to process.
System typically recovers 85 % of the condensate as clean reusable water and has about 15
% reject.
Note:-
a) The quantity of caustic solution required is depends on the characteristics of feed to the
membrane ETP.
b) Phosphoric acid is required for cleaning of the membranes; the frequency of cleaning
depends on the quality of input to the membranes and will establish during operation of
the plant.
5.3.2 Soil Biotechnology Process
Considering the initial capital investment and recurring cost for operation of the
scheme, Soil Bio-Technology appears to be most economical for treatment of process
condensate of distillation, evaporation, RO permeate etc.
The system is designed for treatment of evaporation process condensate or RO permeate
and spent lees of a distillery unit. The process condensate and spent lees treated by such
system can be reused back in to the distillery cooling tower as cooling water make-up
Chapter V
EIA Report: New Molasses based Distillery project Udagiri Sugar & Power Ltd; Dist. Sangli, Maharashtra
5- 7
thereby reducing the requirement of fresh water as well as solving the waste water disposal
to a great extent.
The technology is based on a bio-conversion process where fundamental reactions
of nature, namely respiration, photosynthesis & mineral weathering take place in a media
housing micro & macro organisms which bring about the desired purification. SBT is an
oxygen supplying biological engine and so the process can treat all types of water –
domestic, municipal & industrial. SBT is suitable for treating water with salinity <2500 mg/L.
When salinity levels exceed, reaction rates in the SBT system are lower and hence the
system design is adjusted suitably to achieve the purification desired. If salinity is very high,
an additional facility using RO technology can also be included. The facilities of a treatment
process for water & waste water consists of a raw water tank, bioreactor containment,
treated water tank and associated piping, pumps & electrical. The layout of media on the
bioreactor is shown in Fig 5.2.
Figure 5.2: Layout of SBT Media
5.4 SELECTION OF ALTERNATIVE
Considering all available technological options, the industry has planned to implement
biomethanation followed by multi effect evaporation followed by bio composting for the safe
treatment and disposal of spent wash. It is based on the volume of spentwash to be disposed,
availability of land, press mud for biocomposting and the cost involved for the technology.
In case of CPU the proponent has planned for conventional anaerobic followed by aerobic treatment
supported by tertiary treatment. Treated water will be recycled/ reused in the industry. The
proposed option will be able to achieve the aim of “zero liquid discharge”.

ENVIRONMENT MANAGEMENT PLAN
6.1 OVERVIEW
The Environmental Management Plan (EMP) is a site specific document for the project. It aims to
identify and address the requirements for successfully mitigating the probable adverse
environmental impacts of the project at various stages of project formulation and execution. It also
identifies the post project monitoring requirements needed for the successful implementation of the
suggested measures.
EMP is a framework to ensure that the project can be implemented in an environmentally
sustainable manner and where all concerned persons of the industry as well as contractors,
understand the potential environmental impact arising from the proposed project and take
appropriate actions to properly manage such impact.
The objectives of EMP
Overall conservation of environment and thereby promote sustainable development
Minimization of waste generation and thus pollution
Judicious use of natural resources and water
Safety, welfare and good health of work force and populace
Ensure effective and efficient operation of all control measures
Vigilance against probable disasters and accidents
Monitoring of cumulative and long time impacts
Ensure effective and efficient operation of all control measures
6.2 EMP FOR CONSTRUCTION PHASE
In case of the proposed project, construction activity involves installation of various units of
distillery such fermenters, distillation columns, storage tanks for raw material as well as finished
products, cooling towers, treatment units such as bio-digesters and development of compost yard,
etc.
Thus, the major activities involved for construction phase would be:
Preparation / processing of construction material
Loading / unloading of construction material
Excavation work as per requirement for installation of various structures
Transportation of the material and workers to & from the proposed project location
Installations of various units

Site situation
Well developed asphalted road upto sugar mill and internal road in sugar mill are also
asphalted
On site housing/guest house facility for construction staff and workers
Nearest residential areas are at 2km towards east and 2.4km towards north of the site
Construction activity will be executed through authorized and qualified firms
Greenbelt developed by sugar mill is in place
Considering the various types of pollution associate with the construction activities, recommended
mitigation measures are as follows.
Fugitive dust emission can be controlled by water sprinkling on dust generative surfaces as well
as material such as soil, sand, etc. while loading/unloading
The upper soil layer up to 20-30cm is productive part of the landscape; hence, it should be
carefully removed and preserved for future use. If these soil piles are dry it needs to be covered
with tarpaulin or similar material. This soil could be reused for the development of greenbelt.
The excess of excavated soil could be used for greenbelt by adding adequate amount of manure,
organic fertilizers to it. The material like stones shall be used within the project site, mainly for
minor leveling activities/internal roads, etc
The runoff from the construction site will be controlled by ditches and shall not allowed to
percolate in the surrounding land
The contractor should employ maximum local labour. Thus, the local people will get an
employment opportunity. It will also help in reducing the problems associated with
accommodation/housing of the labour, thus it will help in reducing linked issues such as demand
for water, sanitation and hygiene at the labour colony, etc. However, he should provide the basic
sanitation facility at the work site by using septic tanks and soak pits.
The activities generating noise should be restricted to daytime only
Run-off of loose soil should be prevented by means of compacting the soil
Transport contractors should be instructed to maintain their vehicles properly so as to
minimize the exhaust emissions, reduce the noise and prevent the oil leakages from vehicles.

6.3 EMP: OPERATION PHASE
6.3.1 Air Environment Management
Air Emissions: As summarized in table 6.1, the sources of air pollution are emissions due to
combustion of fuel i.e. bagasse and biogas in the boiler furnace, fugitive dust due to handling of
bagasse, processes such as fermentation, bio-compost, etc. Emissions from diesel generator and
vehicles are anticipated as minor sources. Considering this following management plan is
proposed.
Existing electrostatic precipitator (ESP) as air pollution control equipment (PCE), to arrest
fly ash emissions
Criteria for the design of ESP - mainly based on the characteristics of fuel, its quantity,
generation of pollutant, estimated volume of flue gas, etc.
Flue gases will be released through existing stack of 72 meter height
Preventive maintenance and regular checking of ESP
Fermentor – covered; CO2 scrubber will be installed
Existing of ash and bagasse handling system will be utilize
Proper maintenance of internal roads; greenbelt development along the roads
Biogas produced from the biomethanation process will be utilized as a fuel. In a rare
case if it is unutilized, it will be burnt through flare unit; but in any circumstances it will
not be freely released in the atmosphere
Disposal of potash rich ash by mixing it with compost
Composting process will be carried out in aerobic conditions, by using modern
machines (Aero-tiller) for rotation operations/supply of oxygen
Development of lawn on open areas with plantation of ornamental shrubs/trees in
between so as to reduce the dust generation from open areas and improve aesthetics
Greenbelt of minimum three tiers in the periphery of the project and more in
thickness towards east and west of the site
Monitoring of stack emissions and ambient air quality at regular interval
Compliance of other regulatory norms such as health, safety, etc.
6.3.2 Noise Environment
In case of distilleries, the main processes are fermentation and distillation. In these processes,
there are no major noise sources involved. Hence, simple measures such, as maintenance of
machines, equipments & vehicles, needs to be implemented. Addition measures includes
The noise management practices could be in following sequences
Prevent generation of noise at source by good design and maintenance
Chapter VI
EIA Report: New Molasses based Distillery project
Udagiri Sugar & Power Ltd; Dist. Sangli Maharashtra
6-11
Minimise or contain noise at source by observing good operational techniques and
management practice
Use physical barriers or enclosures to prevent transmission to other media e.g. for
boiler, STG, DG room
Increase the distance between the source and receiver
Sympathetic timing and control for unavoidably noisy operations;
Job rotation for workers placed at high noise areas.
Personnel Protective Equipments will be procure to the workers
Greenbelt development with suitable species for noise attenuation
6.3.3 Water Environment
The Ministry of Environment and Forests (MoEF), has recommended a guideline through
Corporate Responsibility for Environment Protection (CREP), charter. According to these
guidelines, it is mandatory for the distillery to achieve ‘Zero Liquid Discharge’ (ZLD). The project
proponent has developed a plan to achieve ZLD and has made necessary financial provisions
towards the planned activities. Biomethanation followed by the evaporation (MEE) is the
treatment and quantitative reduction of distillery spentwash. Aerobic composting is the disposal
technology to dispose the 120 m3/day for concentrated spentwash
6.3.3.1 CREP guidelines for molasses based distilleries
The industry has opted for Bio-methanation as primary treatment followed by bio composting
for the safe disposal of spent wash. The guidelines recommended through CREP, which will be
implemented by the project proponent, are as follows.
Raw Spentwash Storage lagoon five day storage capacity 1500 m3
Spentwash storage lagoon of ≤30 days capacity 9000 m3
Both lagoons must be impervious, constructed leak-proof, lined with HDPE sheets and
protected by brick lining
The compost yard lined with HDPE sheets and protected with brick/ concrete/
Bituminous Macadam
Provisions for leachate collection gutter and sump well with mechanical provision for
leachat management
A) Land Preparation for Compost Yard
Basic
1. While designing and preparing compost yard, its foundation need to be constructed
with utmost care. Therefore, preparation of the ground & proper compaction plays very
important role in the development of compost yard.
Chapter VI
EIA Report: New Molasses based Distillery project
Udagiri Sugar & Power Ltd; Dist. Sangli Maharashtra
6-12
2. Therefore, it is to ensure that-
The land is leveled and compacted properly
Soft soil cushion is essential to lay a 250 micron thick HDPE sheet
Further, another layer of soft soil/soft sand needs to be provided over the 250
micron thick HDPE sheet before proceeding with the top finish
Provision of underground spentwash spraying network for auto spraying
Provision of leachate management system as per guidelines
There are few options for top finish of compost yard, they are -
Brick on-edge gaps filled with dry sand/soft local soil
Providing Plain Cement Concrete (PCC) 1:3:6 in bays & scaling the joints with
bitumen.
Bituminous asphalting
Providing and laying interlocking concrete paving blocks
The project proponent has opted an impervious compost yard lined with HDPE sheet
and top finish of PCC (1:3:6)
B) Operations & Maintenance Guidelines for Composting
i) Rainy Season
It is not possible to run the aerobic composting process at least for two-three months
during rainy season. The reasons are:
Freshly sprayed spentwash that is yet to be decomposed may give some colored
leachate after rain and will contaminate the soil
Due to rain, the composting material in windrows may have moisture content of 70%,
which can result in anaerobic
It is not possible to run the composting machine during rainy season
Heavy rains can wash off the press mud
Precautions to be taken before onset of rainy season
The composting area must be vacated before start of rains
As far as possible, all the compost on the site should be sold out before start of rain.
The compost, which remains unsold, should be properly bagged and kept in
godown/covered area
After harvesting the last batch of compost a 2 cm layer of pressmud should be
scrapped over the surface layer of compost yard and this scrapped material shall be
kept covered for blending with compost. After cleaning the scrapped area, fresh
windrow of pressmud shall be formed only after rainy season.
Chapter VI
EIA Report: New Molasses based Distillery project
Udagiri Sugar & Power Ltd; Dist. Sangli Maharashtra
6-13
ii) Unseasonal Rains
Precaution to be taken, if there is unseasonal rain during composting cycle
In order to avoid the leaching of spentwash, which is yet to decompose all the
windrows on the yard should be covered with polyethylene sheets/pullover covers
Stop spraying spentwash, temporarily when it is raining. Spraying can be resumed
when the sky becomes clear.
The provision of the trenches towards slopping side should be made to collect the
runoff from windrow area. This runoff should be collected in leachate collection pit.
It should be pumped back to 5 days as well as 30 days storage lagoon.
The run off of outside compost yard should be suitably diverted so that it does not
enter the compost yard.
In order to achieve ‘Zero Liquid Discharge’ the industry will be adopting biomethnation followed
by multi effect evaporation follow by biocomposting process. Impervious lagoons will be
constructed for storage of spent wash and impervious compost yard (1:3:6 PCC) with HDPE
lining as per CREP norms.

Precautionary Measures
Cooling ponds shall be constructed of masonary/brick work with impervious one using
PVC lining duly finished and sulphate resistant cement shall be used. Since the spent
wash is highly acidic in nature, the corrosive resistant epoxy coatings shall be made.
Storage tanks of 30 days and 5 days capacity shall be constructed by providing and
laying leak-proof tar-felt coating and waterproofing primer for joints
Surface windrows should be constructed as described earlier
Bore well towards the downstream of the compost site to check the ground water
quality regularly
Provision to cover the windrows with HDPE sheets, in case of rains
Provision of lined garland drains around the surface compost pits to collect run-off.
6.3.3.4 Operation and Maintenance of Other Pollution Control System
All the pollution control system such as, Bio-methanation, air pollution control (APC)
equipment and any other system provided by the industry should be operated and
maintained strictly as per the operational manual. The record related to this should be
maintained and kept ready for inspection.
The preventive maintenance of all the plant and machinery including civil/mechanical
structure shall be carried out as per the prescribed scheduled.
Housekeeping in and around plant/pollution control system should be maintained
properly.
6.3.4 Land Environment
As discussed in previous chapters, the major threat to land environment is due to percolation of
spentwash / untreated effluent into the soil or disposal of the same by land application etc.
Change in land topography due to installation of various distillery units is another permanent
impact.
Zero Liquid Discharge (ZLD) is aimed for the proposed project and the scheme
recommended for storage, disposal of spentwash and other effluent will comply
CREP guidelines; hence these measures will help to reduce the land pollution due to
spent wash and effluent
Generally, solid & hazardous waste becomes a cause of concern for land
environment; however, in proposed project, the solid waste such as sludge

6.4 GREENBELT DEVELOPMENT
Development of greenbelt in and around an industrial complex is an effective way to attenuate
air pollution. The degree of pollution attenuation is depends upon height, width, foliage, surface
area of leaf and density of species, etc. The Major objectives of the proposed green belt
development will be –
Mitigate impact due to fugitive emissions
Create an aesthetic environment
Enhance the bio-diversity of the vicinity
Help to restore the ground water table
Prevent soil erosion and surface run-off
While planning and designing greenbelt, its various functions will be considered: They are-
Spatio-visual separation of larger parts of the premises

6.5 CONCEPT OF WASTE-MINIMIZATION, RECYCLE/REUSE/ RECOVER TECHNIQUES, ENERGY
CONSERVATION, AND NATURAL RESOURCE CONSERVATION
Industries are going to burn the 11700 m3/day biogas in to the boiler which could save
bagasse to the tone of 22 MT per day
Recycle of 255 m3/day of treated water (spent lees and process condensate water) after
polishing treatment, for cooling tower make up. This practice reduces the fresh water
requirement
6.6 RAIN WATER HARVESTING
Rain water is one of the purest sources of water for improving the water table and water quality
in the sub-soil. Rain water which is otherwise wasted has to be recharged in to the soil. This can
be adopted eitherusing traditional way or by modern technologies. The various types of rain
harvesting schemes are, diverting rain water collection through proper channels to the nearest
pond or open wells and run off from built in areas mainly roofs are diverted to storm water
drains, which is again taken to the nearest lake / pond.
The other method of rain water harvesting is ground water recharging. In this option, the
recharging structures should be prepared in scientific way. Recharging pits of size approx. 2x2 m
and 3m depth need to be constructed and filled with pebbles/rubbles of sizes more than 2”. At
the center of this structure 6” or 8” pipe is driven to the depth of approx.10m, with perforation
of 1or2”. Such structures can be built at pre-defined places (minimum 4 or 5 places, depending
up on the site situation) so that maximum quantity of rain water within the premises of sugar
factory can be collected. The water diverted through channels, from roof tops and other means
can be collected in this recharge structure, which will definitely improve the water table as well
as quality of the water and feed water to the plant during drought season.
The industry has planned rainwater-harvesting project by harvesting rain water from roof top
areas of building and structures of sugar unit only. This selection was mainly considering
contamination as well as other feasibility factors. All the rain water is collected, filtered and
channelized to spray pond, where it is stored. The dimensions of spray pond are 30x30x3m, that
offers a volume of 2700 cu.m. for rain water storage.

CHAPTER VII
RISK ASSESSMENT AND MANAGEMENT
7.1 INTRODUCTION
Risk associated with the use of hazardous chemicals can be assessed and managed in terms of their
effect on human health, environmental health, and business operations, in general. When discussing
a particular chemical substance, each of these categories should be examined to ensure a
comprehensive understanding of a total risk and to provide the basis for an acceptable risk
management programme.
Presence of a chemical commodity in the work place or the environment in general, generates some
level of risk. Assessing the nature or severity of this risk is dependent upon a number of factors, all of
which focus on one common element: exposure. In assessing a risk a questions of exposures must
consistently be asked. Are personnel being exposed? Is there an exposure to the environment? What
is the risk to continue success in business operations if there is an exposure to personnel and/or the
environment? Therefore, risk assessment, which is the basis for risk management, is partially
contingent upon an understanding of term ‘Exposure’.
However, an exposure to chemical doesn’t always mean that the results will be detrimental. If such
exposure occurs (i.e. those with no detrimental or adverse effect to human health, the environment
or business operation) then additional question must be asked – what is the nature of the risk
associated with such exposure? Are these exposures hazardous or toxic? Hence, it is not always
enough to have experienced an exposure to a chemical to accurately assess the risk posed by such.
One must determine (assess) if the exposure was also hazardous before the level or nature of risk
can be properly identified. In other words, the specific hazardous of an exposure that present risk to
a person and/ or the environment must be examined. It becomes clear that the risk assessor or risk
manager must understand the principals of hazard, exposure, and risk.
7.2 THE RISK EQUATION
Risk is the probability that the hazard will occur (i.e. that an adverse effect or/event will
result from a given set of exposure condition). Since the risk is typically expressed as a mathematical
probability, the range of risk can be stated as zero (having no possibility of adverse effect or event).
One (having a certainty that an adverse effect or event will result) having established this, it is
important to note that risk is the mathematical product of hazard and exposure. This relationship
can, be expressed in the following simple formula.
Chapter VII
EIA Report: New Molasses based Distillery project Udagiri Sugar & Power Ltd; Dist. Sangli, Maharashtra
7-2
Risk = Hazard x Exposure
Simple Mathematics tells us that, multiplying any number by zero forces a product of zero.
Therefore, the above equation means that an extremely hazardous substance can be present with
little risk of adverse effect if it is handled with safe and proper conditions (i.e. when the exposure
component of the risk equation is driven towards zero). Similarly, risk can be reduced towards zero
by driving the hazard component of the equation towards zero (e.g. changing the process design,
substituting less hazardous commodity, using a lesser amount of a chemical, etc.), even if there is
still a high probability of exposure. Of course, the ultimate risk management solution would be
driving both the exposure and the hazard components of the equation to as low probability as
possible. Such measures would virtually guarantee a low or no risk scenario; however, in the real
world of everybody, operations, it is not always practical, feasible, or possible to reduce the
elements of risk to zero level or probability. For this reason, risk assessment and risk management
have become extremely vital element to successful business operations in recent years. More
importantly, the proper assessment and management of risks, which may be pose by the use,
transport, storage, or disposal of hazardous chemical can be laterally save lives, prevent illness and
injury and preserve the precious environmental resources.
7.3 HAZARD IDENTIFICATION
7.3.1 Mechanical Hazard
It mainly involves properties of machine parts or work pieces, such as:
a. Shape: It may cause injury to workman
b. Relative location: Confined location during repairs & maintenance
c. Mass and stability: May cause physical Injury
d. Inadequacy of mechanical strength
e. Accumulation of energy inside the equipment: steam/ air /water pressure cause injury to
workman
f. During commissioning, Operation and Maintenance of plant Crushing hazard, shearing
hazard, Cutting or severing hazard, Friction or abrasion hazard and High pressure fluid
injection or ejection hazard can not ruled out
7.3.1.1 Mechanical injury to body parts
g. In industry, there are several places where workers are likely to be involved with accidents
resulting in injury to body parts. The places are workshop, during mechanical repair work in
different units, during construction work, road accidents due to vehicular movement, etc
Chapter VII
EIA Report: New Molasses based Distillery project Udagiri Sugar & Power Ltd; Dist. Sangli, Maharashtra

h. Workers exposed to mechanical accident-prone areas will be given personal protective
equipment. The non-respiratory PPE includes tight rubber goggles, safety helmets, welders
hand shields and welding helmets, plastic face shields, ear plugs, ear muffs, rubber aprons,
rubber gloves, shoes with non-skid soles, gum boots, safety shoe with toe protection.
i. All safety and health codes prescribed by the BIS will be implemented. Fire hydrants will be
located at all convenient and strategic points along the major drains and checked for water
availability on regular basis. Fire extinguishing equipment, sand buckets, water sprinklers,
and water hoses will be provided at all convenient point. Fire, heat, smoke, and hydrocarbon
detection alarms will be installed.
7.3.2 Electrical Hazard
Probable incidences for electrical hazards, could be
a. Contact of persons with live parts (direct contact),
b. Contact of persons with parts which have become live under faulty conditions (indirect
contact),
c. Approach to live parts under high voltage,
d. Electrostatic phenomena,
e. Thermal radiation or other phenomena such as the projection of any particles and
chemical;
f. Effect of short circuits, overloads, etc identified during construction, production and
maintenance
7.3.3 Thermal Hazard
Probable causes of thermal hazards could be -
a. Burns, scalds and other injuries by a possible contact of persons with objects or materials
with an extreme high or low temperature, by flames or explosions and also by radiation of
heat sources
b. Damage to health by hot or cold working environment
c. Thermodynamic Hazard such as over/under pressure, over/under-temperature need to be
avoided by providing system management
7.3.4 Hazard generated by noise
In the proposed project probable source of noise are – boiler, motors and pumps,
etc. Usually prolong exposure to high noise level, results into
1. hearing loss (deafness), other physiological disorder (e.g., loss of balance, loss of
awareness)

In the proposed project the hazard due to vibrations could be due to -
1. Use of hand-held machines resulting in a variety of neurological and vascular disorders
2. Whole body vibration, particularly when combined with poor postures
7.3.6 Hazards generated by materials/substances
1. Hazards from contact with or inhalation of harmful fluids such as: Anti rusting chemicals,
Cleaning agents/acids/organic solvents gases, Superheated steam through leaks, bagasse
dust, etc.
2. Fire hazard — dry bagasse, alcohol and molasses storage area, furnace
3. Biological or microbiological (viral or bacterial) hazards:-Workplace exposure to dusts from
the processing of bagasse can cause the chronic lung condition pulmonary fibrosis.
7.3.7 Preliminary Hazard Analysis (PHA)
Preliminary hazard analysis (PHA) is a semi-quantitative analysis that is performed to identify all
potential hazards and accidental events that may lead to an accident, rank the identified accidental
events according to their severity, and identify required hazard controls and follow-up actions. This
tool analysis is based on applying prior experience or knowledge of hazard to identify future hazards,
hazardous situation. This can be used for product, process and facility design. This can be used in
early development of a project where there is little information in detail is available.

7.6 RISK ASSESSMENT: HEALTH
7.6.1 General Assessment
The toxicity of ethyl alcohol is much lower in comparison to methanol or propanol. Ethyl alcohol is
primarily toxic to humans by ingestion. While inhalation of its vapors can produce some toxic effects,
its ability to enhance the effects of other chemicals poses a greater health risk for inhalation. Skin
contact can cause topical damage and absorption is, therefore, not likely. It should be noted that
most manufacturers of ethyl alcohol for use in industrial applications would normally mix it with a
denaturant (a substance added to make it un desirable to drink). These include gasoline, acetone,
formaldehyde, or methyl alcohol. Therefore, industrial exposures resulting from ingestion are very
unlikely.
Inhalation can cause irritation of the eyes, nose, throat, upper respiratory tract, and associated
mucosa. There may be headache, nervousness, tremors, dizziness, tearing, fatigue, nausea,
somnolence, and narcosis with stupor and loss of consciousness. There are no reports of cirrhosis
occurring as a result of inhalation exposures. However, chronic exposure to ethyl alcohol vapors
caused brain damage in mice. Vapor exposure can also increase the toxic effects of other chemicals
being inhaled. Also, the toxicity of ethyl alcohol is enhanced with the presence of compounds such
as barbiturates, carbon monoxide, and methyl mercury.
Liquid contact with the eyes causes immediate burning and stinging with lachrymator and reflex
closure of the lids. There may be injury to the corn epithelium and possible hyperemia (excessive
blood) the conjunctiva. Skin contact results in drying cracking, which can lead to secondary
infections dermatitis.
Ingestion of ethyl alcohol is not likely to occur in the industrial environment. However, if it does,
symptoms can include sleep disorders, hallucinations, distorted perceptions, ataxia, motor function
changes, convulsions and tremors, coma, headaches, pulmonary changes, alteration of gastric
secretions, menstrual cycle changes, glandular changes, nausea or vomiting, and decrease in body
temperature.
Chapter VII
EIA Report: New Molasses based Distillery project Udagiri Sugar & Power Ltd; Dist. Sangli, Maharashtra
7-16
7.6.2 Acute Health Effects
The following acute (short-term) health effects occur immediately or shortly after exposure to
alcohol.
Skin Causes dryness and cracking leading to dermatitis and possible
infection.
Eye Severe irritation with burning and possible damage to the cornea and
conjunctiva.
Lung Irritation of the eyes, nose, throat, and respiratory tract.
Central Nervous
System (CNS)
High concentrations can cause depression the CNS with symptoms of
sleepiness and I of concentration.
7.6.3 Chronic Health Effects
The following chronic (long-term) health effects occur at some time after exposure to ethyl alcohol
can last for months or even years:
Cancer Hazards: Ethyl alcohol is known to cause liver cancer in humans, primarily due to
ingestion. Industrial exposures through ingestion are not likely but are
certainly possible.
Reproduction: According to the references, ethyl alcohol can affect human reproduction
by ingestion. It causes changes in the female fertility index. Effects on
newborns include changes in the apgar score, neonatal measures or
effects, and drug dependence.
Other Chronic Effects: Very high or prolonged expo- sure may result in mucous membrane
irritation, head- ache, and depression of the CNS with symptoms of
somnolence and lack of concentration. Prolonged skin contact can cause
dermatitis.
7.6.4 Recommended Risk-Reduction Measures
Even though ethyl alcohol is a known carcinogen, this effect is primarily the result of ingesting large
amounts of alcoholic beverages. Industrial exposures by this route are not likely to occur. The best
risk reduction measure is to use a less toxic chemical as a substitute for an ethyl alcohol. However,
based upon the fact that ethyl alcohol is one of the most widely used industrial solvents, substitution
is usually not an alternative. Therefore, engineering controls are the most effective methods of
Chapter VII
EIA Report: New Molasses based Distillery project Udagiri Sugar & Power Ltd; Dist. Sangli, Maharashtra
7-17
reducing exposures. The best protection is to enclose operations' and/or provide local exhaust
ventilation at the site of chemical release. While not always operationally feasible, isolating
operations can also reduce exposure risk.
Using respiratory protection is less effective than the controls mentioned above, but is still advisable
whenever working with or around ethyl alcohol. For concentrations over the Permissible Exposure
Limit (PEL i.e. 1000 ppm), an air-purifying respirator with an organic vapor cartridge will suffice. For
higher exposures, a supplied-air respirator with full face piece operated in positive pressure mode,
or a self-contained breathing apparatus (SCBA) with full face piece and operated in pressure demand
mode are the recommended respiratory protection methods of choice. If a full face piece is not
available, then chemical goggles should be worn to protect the eyes. Whenever a chemical splash
hazard exists, a face shield and a protective apron should be worn. To pre- vent hand and skin
exposures, impervious gloves should be used.
Administrative controls should also be in place to minimize the potential for human exposures.
These may include written procedures or policies, which specify the methods and techniques that
will be practiced whenever personnel are to work with ethyl alcohol.
All personnel should receive training on- the use, hazards, protective measures, emergency actions,
and other precautions per 29 CFR 1910.1200 (Hazard Communication), prior to the first assignment
in an area where ethyl alcohol is used or stored. If symptoms develop or overexposure is suspected,
the following medical tests are recommended
a. Liver function tests;
b. Skin testing with dilutes ethyl alcohol to help diagnose allergy (performed by a
qualified allergist).
Any medical evaluation should include a careful history of past and present symptoms with an
examination. Medical tests that look for existing damage are not a substitute for controlling
exposures. Also, since consuming large quantities of alcoholic beverages can lead to liver dysfunction
and even cancer, persons with alcohol addiction who arc exposed to ethyl alcohol on the job may
develop symptoms much quicker and with greater intensity than those who do not drink under
identical exposure conditions. Prudent risk management requires careful consideration of all
possible factors that may be causing the appearance of exposure symptoms.
7.6.5 Other Methods to Reduce Exposure
Chapter VII
EIA Report: New Molasses based Distillery project Udagiri Sugar & Power Ltd; Dist. Sangli, Maharashtra
7-18
1. Where possible, enclose operations and use local exhaust ventilation at the site of
chemical release. If local exhaust ventilation or enclosure is not used, respiratory
protection should be mandatory.
2. Always ensure that proper protective clothing is worn when using chemical
substances.
3. Wash thoroughly immediately after exposure to ethyl alcohol and at the end of the
work shift or before eating, drinking, or smoking.
4. Hazard warning information should be posted in the work area. In addition, as part
of an on-going education and training program, all information on the health and
safety hazards of ethyl alcohol should be communicated to all potentially exposed
workers.
7.7 RISK ASSESSMENT: ENVIRONMENT
7.7.1 General Assessment
The environment is at risk of exposure during transportation, storage, disposal, or
destruction of ethyl alcohol. In almost every scenario, the threat of environmental exposure is
contingent upon the proper handling of the chemical substance. Accidental spills, large or small, can
result in fire, explosion, and possible contamination of the surrounding environmental mediums
(water, soil, and air).
Ethyl alcohol is considered a class IB flammable liquid (according to OSHA 29 CFR 1910.106). Its low
flash point and relatively low boiling point present a serious fire and explosion hazard concern. Also,
because it is incompatible with a number of common materials, especially strong oxidizers and many
metal nitrates, contact can result in violent and explosive reactions. It can form explosive mixtures in
air and can ignite on contact with heat, fire, or sparks. It will react and then explode in contact with
acetic anhydride + sodium hydrogen sulfate. It also reacts violently with acetyl bromide (evolves
hydrogen bromide). These characteristics require special consideration during any emergency
situation involving a leak or spill of ethyl alcohol.
Ethyl alcohol can enter the environment through unchecked industrial discharges into effluents and
through spills.
7.7.2 Acute Ecological Effects
Acute (short-term) toxic effects may include the death of animals, birds, or fish, and death or low
growth rate in plants. Acute effects are seen 2 to 4 days after animals or plants are exposed to ethyl
Chapter VII
EIA Report: New Molasses based Distillery project Udagiri Sugar & Power Ltd; Dist. Sangli, Maharashtra
7-19
alcohol. This chemical has moderate acute toxicity to aquatic life. Insufficient data are available to
evaluate or predict the short-term effects of ethyl alcohol to plants, birds, or terrestrial animals.
7.7.3 Chronic Ecological Effects
Chronic toxic effects may include shortened life span, reproductive problems, lower fertility, and
changes in appearance or behavior in exposed animals. These effects can be seen long after first
exposure(s) to toxic chemicals. Ethyl alcohol has moderate chronic toxicity to aquatic life. Insufficient
data are available to evaluate or predict the long-term effects of ethyl alcohol to plants, birds, or
land animals.
Water Solubility: Ethyl alcohol is highly soluble in water. Concentrations of 1000 milligrams and more
can be expected to mix with a liter of water.
7.7.4 Persistence in the Environment
Ethyl alcohol is slightly persistent in water, with a half- life of between 2 to 20 days. The half-Life of a
pollutant is the amount of time it takes for one-half of the chemical to be degraded. About 90% of
ethyl alcohol will eventually end up in the air; the remainder will end up in water.
7.7.5 Bioaccumulation in Aquatic Organisms
Some substances increase in concentration, or bioaccumulate, in living organisms as they breathe
contaminated air, drink contaminated water, or eat contaminated food. These chemicals can
become concentrated in the tissues and internal organs of animals as well as humans. The
concentration of ethyl alcohol found in fish tissues is expected to be about the same as the average
concentration of ethyl alcohol in water from which the fish was taken.
7.7.6 Recommended Risk-Reduction Measures
Proper training of all transporters will reduce the likelihood of a mishap or accident resulting
in a leak or spill to the environment. The correct labeling while transportation on all transporting
vehicles should be enable emergency responders to react properly and quickly to any disaster
thereby reducing the potential risk to the environment and to personnel.
Storage of ethyl alcohol should be segregated from incompatible chemicals to minimize the risk of
cross contamination or contact. Buildings designated for storage should be equipped with
appropriate fire protection systems (alarms, sprinklers, emergency lighting, portable extinguishers).
Equipment should be designed to meet explosion-proof standards.
If a spill or leak to the environment has occurred, fire department, emergency response, and/or
hazardous materials spill personnel should be notified immediately. Cleanup should be attempted
Chapter VII
EIA Report: New Molasses based Distillery project Udagiri Sugar & Power Ltd; Dist. Sangli, Maharashtra
7-20
only by those trained in proper spill containment procedures. Contaminated soils should be removed
for incineration and replaced with clean soil. If ethyl alcohol should contact the water table, aquifer,
or navigable waterway, time is: of the essence. It is highly soluble in water and, therefore, total
containment and remediation may not be entirely possible. When such spills occur, the local and/or
state emergency response authorities must be notified. A comprehensive emergency response of
disaster preparedness/recovery plan should be in place prior to any operations involving the use,
transportation, storage, or disposal of ethyl alcohol. If ethyl alcohol is spilled or leaked, the following
specific steps are recommended:
a. Restrict persons not wearing protective clothing from area of spill or leak until cleanup is
complete and area can be opened for normal work.
b. Ventilate area and remove ignition sources.
c. Absorb liquids in vermiculite, dry sand, earth, or a similar material and deposit in sealed
containers. Use non-sparking tools.
d. It may be necessary to dispose of ethyl alcohol as a hazardous waste. The state PCB should
be contacted for specific recommendations.
Chapter VII

7-21
7.8 RISK ASSESSMENT: BUSINESS
7.8.1 General Assessment
Accidents or mishaps involving ethyl alcohol can present a moderate threat to business operations.
The loss or damage of equipment or facilities can significantly affect fiscal viability. Lawsuits that
may result from personnel injury/death, public exposures, and/or environmental contamination will
also require a serious expenditure of resources. Media attention surrounding an injury, death, or
environmental damage can also result in a loss of profits and loss of current as well as future
business.
Recommended Risk-Reduction Measures
Company attorneys, safety and health professionals, and environmental specialists should be
involved in the development of any procedures or policies intended to manage the use of chemicals
in the workplace. A company official should be pre-designated as a public relations officer with
specific training in dealing with the press. Corporate plans and policies should be developed,
approved, and implemented long before any need for such arises.

CHAPTER VIII
DISASTER MANAGEMENT PLAN
8.1 INTRODUCTION
According to the UN International Strategy for Disaster Reduction, (UNISDR) “A Disaster is
a sudden, calamitous event that causes serious disruption of the functioning of a community
or a society involving widespread human material economic or environmental losses and
impacts which exceeds the ability of the affected community or society to cope using its own
resources.”
Disaster Management is – "it is action taken to prevent Hazard converting into Disaster". A
major disaster in a work is one which has potential to cause serious injury or loss of life. It
may cause extensive damage to property and serious disruption both inside and outside the
work. Normally, assistance of outside emergency services is required to handle disaster
situation effectively. Whatever are the causative factor like plan failure, human error,
earthquake, lightning, vehicle crash sabotage etc. they will normally manifest in three basic
forms viz. fire, explosion and/or toxic release.
Pre-disaster planning is crucial for ensuring an efficient response at the time of a disaster. A
well-planned and well-rehearsed response system can deal with the exigencies of calamities
and also put up a resilient coping mechanism. Optimal utilization of scarce resources for
rescue, relief and rehabilitation during times of crisis is possible only with detailed planning
and preparation. Keeping in view these factors, preparation of Disaster Management Plans
(DMP) is imperative.
8.2 SCOPE
Disaster: A serious disruption of the functioning of a society, causing widespread human,
material or environmental losses which exceed the ability of the affected community to cope
up by using its own resources.
Hazard: Hazard is an event or occurrence that has potential for causing injury or loss of life
or damage to property or the environment. Following factors are considered to identify
Hazard -
Physiology of the Hazard or and its peculiar characteristics.
Impact & probability of occurrence
The elements by affecting, Life / Property or environment, likely to get affected

The geographic region of the proposed project may face probable hazards such as
earthquake, drought, thunder storms, accidents and environmental hazard such as pollution,
etc. So considering these probabilities, the disaster management plan is being
recommended.

8.3 DISASTER MANAGEMENT PLAN (DMP) CYCLES
Disaster management is a methodology to understand and face disaster and take
appropriate measures to minimize the losses of life, property and environment. This can be
represented in 3 sections namely – Pre disaster phase, During disaster and Post situations.
Pre disaster activities
1. Policy development and local level disaster organization formation
2. Vulnerability and capacity assessment
3. Prevention and mitigation
4. Preparedness, planning and training
Emergency activities
1. Warning (beginning before the actual event)
2. Evacuation, search and rescue
3. Emergency assistance (relief) – food, water, shelter, medical aid
Post disaster activities
1. Repair and restoration of life lines (power, telecommunications, water transportation)
2. Reconstruction and rehabilitation
8.3.1 Pre-disaster situation
Preventive measures
Earth quick resistant construction as per National Building code and considering the
factory is located in seismic zone III.
Analyze soil type before construction and do not build structures on soft soil. To
accommodate on weak soils adopt safety measures in design.
Follow Indian Standard Code for construction of buildings
Enforcement of building code in the byelaws
Land use control and restriction on density and heights of buildings
Strengthening of important buildings, which need to be functional after a disaster.
Upgrade level of safety of buildings.
Reduce possible damages from secondary effects. e.g., identify potential sites and restrict
construction in those areas.
In earthquake prone areas insurance should be obtained for buildings under
construction and those in use. Insurance policies for natural disasters is mandetory
and priced specifically on available scientific data of hazards in the region.
Chapter VIII
EIA Report: New Molasses based Distillery project
Udagiri Sugar & Power Ltd; Dist. Sangli, Maharashtra
8-6
Preparation of disaster related literature in local languages with dos and don'ts for
construction.
Getting communities involved in the process of disaster mitigation through
education and awareness.
Networking of local NGOs working in the area of disaster management.
Preparedness is a process that enables the authority to respond rapidly to disaster situation.
It helps to cope-up with the situation effectively so that the extent of damage due to
disaster or emergency situation could be kept at minimum level. Preparedness includes the
formulation of plans at various levels, to be executed in pre disaster phase as well as, during
disaster and post disaster situation. These plans can be prepared by each of the department.
Factors, such as early warning systems, preparation of role and responsibilities of various
stake holders, conducting training, mock drills at various are included in this phase. In this
phase, capacity building, preventive measures, mitigation activities take front seat. This is
the time before disaster. With the past lessons learnt, and in anticipation of likely
occurrence of disaster, many activities could be carried-out to reduce the impact, and
spreading of Hazard. Therefore, disaster planning becomes a necessary element for
mitigating the effects of a major accident/ disaster.
In the preparedness phase, emergency managers develop plans of action carefully to
manage and counter probable risks and take action to build the necessary capabilities
needed to implement such plans. Common preparedness measures include:
Communication plans with easily understandable terminology and methods
Proper maintenance and training of emergency services, including mass human
resources such as community emergency response teams
Development and exercise of emergency population warning methods combined
with emergency shelters and evacuation plans.
For evacuation, a disaster supplies kit may be prepared and for sheltering purposes a
stockpile of supplies may be created. The preparation of a survival kit such as a "72-
hour kit", is often advocated by authorities. These kits may include food, medicine,
flashlights, candles and money. Also, putting valuable items in safe area is also
recommended
Stockpiling, inventory, streamline foods supplies, and maintain other disaster
supplies and equipment
Chapter VIII
EIA Report: New Molasses based Distillery project
Udagiri Sugar & Power Ltd; Dist. Sangli, Maharashtra
8-7
Develop organizations of trained volunteers among civilian populations. Professional
emergency workers are rapidly overwhelmed in mass emergencies so trained,
organized, responsible volunteers are extremely valuable
It is realized that investment on Preparedness, Prevention and Mitigation is more cost-
effective compared to expenditure on relief and rehabilitation. The basic characteristic of
disaster management is ‘proactive’ prevention, preparedness and mitigation rather than the
prevalent ‘re-active’ relief and rehabilitation approach. Management of risks as a prelude to
crisis management has now gradually gained importance.
Disaster management planning is not a substitute for good operative/maintenance/ design
practice. It is an aspect of safety management. Every industry, as mentioned above, should
minimize risk by adherence to safe practice and meeting all legislation.
On-site disaster management planning is responsibility of project management (i.e.
occupier). The district authorities and the Directorate of Industrial Safety and Health have
the responsibilities for off- site Disaster management plan of the district.
The proposed distillery unit needs to have a round-the-clock team to manage disaster. The
team shall include several members. Their functions depend on size of the organization and
it shall be headed by a technically qualified as well as a trained individual.
8.3.2 Response
The response phase includes the mobilization of the necessary emergency services and first
responders in the disaster area. This is likely to include a first wave of core emergency
services, such as firefighters, police and ambulance crews. In some instances, it is termed
Disaster Relief Operation (DRO) and can be a follow-up to a Non-combatant evacuation
operation (NEO). They may be supported by a number of secondary emergency services,
such as specialist rescue teams.
A well rehearsed emergency plan developed as part of the preparedness phase enables
efficient coordination of rescue. Where required, search and rescue efforts commence at an
early stage. In this particular section the response plan is discussed in details.
The response plan of Disaster Management Plan is crucial and it includes the following
Controlling the disaster, localizing the disaster and eliminating the hazard, if any
Minimizing damage to property and environment
Safeguarding others by timely evacuation
Welfare of person managing the disaster
Head count and rescue operations

9.3 BENEFITS TO COUNTRY: ALCOHOL AS A FUEL
Ethanol is mainly produced from sugarcane molasses. Sugarcane is a renewable source of
energy. Sugarcane cultivation is an efficient method of converting ‘solar energy’ into ‘stored
energy’. Thus, use of ethanol as oxygenating agent or fuel-extender would conserve fossil fuels
and would reduce dependence on fossil fuels.
Addition of fuel-ethanol to petrol has several advantages, especially in a country like India. Use
of ethanol in place of tetraethyl lead or MTBE will prevent dangerous and poisonous emissions
containing lead or MTBE from petrol. It will not require any catalytic converter for the vehicles.
Use of ethanol in petrol reduces emission of carbon monoxide. This will reduce pollution, since
this is a major cause of vehicular pollution in India. Ethanol is made from renewable sources of
energy i.e. based on agricultural products. Thus, it is not a depleting resource like petrol.
Use of ethanol helps in maintaining the ‘carbon cycle’ of nature. Carbon dioxide in the
atmosphere is converted by agricultural crops like sugarcane or corn into carbonaceous
materials like sugar and starch using solar energy. This sugar or starch can be converted into
ethanol. This ethanol is used in vehicles to produce energy along with petrol. This combustion
in internal combustion engines converts ethanol into carbon dioxide. This carbon dioxide can
again be converted into sugar or starch. Thus, the ‘carbon cycle’ of nature continues.
This ‘carbon cycle’ uses solar energy, which otherwise would have been wasted.
Use of fossil fuels alone to generate energy only increases content of carbon dioxide in the
atmosphere, disturbing the natural balance. Sustaining the ‘carbon cycle’ reduces the
‘greenhouse effect.’ Use of ethanol, which is mostly a ‘home grown’ product reduces
dependence on the politically sensitive Middle – East region. India has vast agricultural waste
resources like sugarcane molasses to gainfully convert into ethanol.
Blending of petrol using ethanol even at 5% directly saves that much petrol. Thus, we could
reduce import of crude oil by 5%. This quantity is huge at national level. Hence, we could able to
save valuable foreign exchange and strengthen our economy. This could also help in
controlling/regulating the prices of petrol in the market, since ethanol is cheaper compared to
petrol. Overall, it could have manifold effect on economy.

9.4 ENVIRONMENTAL BENEFIT ANALYSIS
Raw material i.e. molasses and bagasse is readily available from the sugar factory
Solid filler materials like press mud to dispose the highly concentrated spentwash
is readily available within sugar factory
Hence, saving of raw material as well as filler materials transportation cost and
fuel,
Disposal of molasses, press mud and ash will get solved due to the proposed unit
Generation of energy (Biogas) from wastewater i.e. spentwash; thus, direct
emission of methane will get avoided. Methane is a green house gas having 23
time higher global warming potential than carbon dioxide
Utilization of Biogas as a fuel for boiler and thus saving more bagasse for off-
season that will be utilized for cogeneration activity
Recycling of soil nutrients by bio-compost; thus, Increasing soil fertility
Recycling/reuse of treated water will save fresh water intake
Exhaust steam from cogeneration unit will be used for distillery operations,
hence it will save energy (fuel) as well as water
Sugar factory solid waste like press mud, ash and waste sludge from ETP can
covert in to the bio-manure
