INTRODUCTION
• 1000 cubic m/day plant started in Dec 2012.
• At Gaushala with about 3000 cattle
• Dry cows with about 20 tons of dung/day
• Selection of this Gaushala – based on business minded trustees.
• Plant on BOO (Build, own and operate) basis.
• Land leased by Gaushala for 20 years.
• Dung @ Rs 125 per ton.
• 10% of revenue from Bio CNG to Gaushala.

Technology
• Retention Time = 5 days
• Continuous Flow (24x7 operation)
• 70% methane
• Pre-engineered, modular, scalable design
• Computerized and automated operation
• Low maintenance as few moving parts.
• Consistent fibre quality of the organic
manure

Technology
• PSA for purification
• 95.8 % methane, (CO2 = 3.8%, O2 = 0.1%,
H2S below 2 ppm, N2= 0.3%)
• Scrub through water could have been
cheaper solution.
• Compressed to 150 bars
• Filled into cylinders/bottles through manifold.

Organic Manure
• Organic Manure is also having very
fibrous & very rich in “total organic carbon
matter (32.7%)” which helps plants in
nitrogen fixation and improving the soil -
Confirmed by Shriram Institute for
Industrial Research.
• Farmers of local area are using our bio
manure repeatedly in their farms.
• Kribhco has agreed to purchase from us

Economics
• Revenue: Bio CNG = 400-500 kg/day @
Rs 50/kg.
• Revenue: Bio-Fertilizer = 5-6 tons/day @
Rs 2- 4 per kg.
• A new plant of this size = Rs1.75 Crores
• PBP for a new plant = 3 years
• First Plant = Rs 3 Crores as lots of
learning cost

Challenges Faced
• A large number of clearance – takes away time, energy,
money and kills enthusiasm – not commensurate with
the size of the plant. MNRE could become a single
window clearance agency.
• Contamination in form of husk – choked pumps, heat
exchanger, valves and pipe lines. Solution – new two
additional mixing tanks and alternative decantation
processes.
• Separation of water from the slurry for fibrous manure –
we developed our own design.
• Disposal of separated water – recycled for making slurry.
Also, separated water has been sold to the farmers free
of charge.

Challenges Faced
• Corrosion due to dung – use of stainless steel and PVC
materials.
• Weight of cylinders – the cylinders approved for filling
Bio CNG by PESO is about 100 kg – imagine for storage
of 10 kg of Bio CNG, we have to use 100 kg cylinders –
MNRE should make a guidelines for PESO.
• Selling manure in Haryana – requires license – MNRE
may please take it up with the state govt.
• Selling Bio CNG – had to market, prove to users, trial
and test. This is finally accepted by the market – final
users : metal cutting industries, metal coating industries,
commercial kitchen.
• Sourcing of cow dung – gaushala has difficulty in
supplying dung – procure dung from different gaushalas.

FAQ
• Can this technology be used on other organic wastes? –
Yes, food waste, fruit and Veggie mrkt waste, paultry, etc
• Is purification and compressing to make Bio CNG for
such plant’s capacity an attractive proposition? –
Commercially not advisable but for I would still do it!
• Should Government support energy generation through
Bio methanation – Yes. Look at the German model ( 21
Euro cents per unit!)
• Should there be a collaboration between different
technologies available? Yes, IIT Delhi may take a lead.
