Glass
bull Nobody knows when where or how people first learn how to make glass
bull The first manufactured glass was found in Mesopotamia about 3000 BC
bull First glass vessels were made about 1500 BC in Mesopotamia and Egypt
bull In that time making glass was slow and costly because of the poor quality and low effective furnaces
3000-year-old glass furnace
Burnt with pine woods
The new glass furnace
Glass The invention of the blowpipe in about 30 BC made the glass production easier faster and cheaper and the glass became available for common people for the first time in history
Glass Today 90 of the flat plate is manufactured by the float process which was developed by the Britain Pilkington Brothers Ltd in 1959
What is Glass
Glass can be manufactured by melting at a 1600 oC a mixture of bull Silica ( SiO2) bull Sodium carbonate (Na2CO3) bull Dolomite (CaMg(CO3)2) bull Limestone (CaCO3) bullAdditives like metals to give glass its color Then the mixture is cooled to solidify without crystallization
The chemical composition in general
Raw materials for glass manufacture bull Silica sand (SiO2) about 72 bull Soda ash (sodium carbonate) (Na2CO3) about 17 bull Limestone (CaCO3) about 5 bull Additives like metals to give glass its color about 6
Raw materials for glass production
Types of glass
1 Soda glass or Soda-lime glass (about 80 of all kinds of glass)
It is the most common type that are used for making windowpanes tableware bottles bullbs and all kinds of containers
2 Borosilicate glass
bull glass containing 5 percent or more of B2O3 (Boron oxide) highly resistant to heat and shock due to the very low coefficients of thermal expansion ( about 3 times 10minus6 degC at 20degC)
bull Used for making Chemical apparatus for Pharmaceutical and Tungsten sealing
3 Lead glass
bull Lead glass contains typically 18ndash40 by weight of lead(II) oxide (PbO)
bull Used for Color TV funnel Neon tubing Electronic parts and in Optical dense flint like glasses
4 Barium glass
bull Without this type of glass watching TV would be very dangerous A television produces X-rays that must be absorbed otherwise they could in the long run cause health problems The X-rays are absorbed by glass with minimum amounts of heavy oxides (lead barium or strontium) Glass containing barium is used for the TVs screen Other uses in the Optical dense barium crown
5 Aluminosilicate glass
bull A small but important type of glass aluminosilicate contains 20 aluminium oxide (alumina-Al2O3) often including calcium oxide magnesium oxide and boric oxide in relatively small amounts but with only very small amounts of soda or potash It is able to withstand high temperatures and thermal shock and is typically used in combustion tubes gauge glasses for high-pressure steam boilers and in halogen-tungsten lamps capable of operating at temperature as high as 750degC
Other types of glass and their percentages (in EU)
Production rate of glass in Europe
The production rate of glass in the world
bull The world total production of glass was about 894 million tons in 2007
bull EU countries produced about 383 million tons in that year About 30 of the total production makes Europe the largest glass producer
bull The production rate is expected to increase due to the increase in the industrialization and the improvement in the standard of living
How much raw materials we need to produce 1 kg of glass
bull Each 1 kg of sheet glass needs 173 kg of raw materials and 015 m3 of water
While we need 12-13 kg of raw materials to produce 1 kg of container glass
How much energy we need to produce 1 kg
of glass
bull Glass industry is considered one of the most intensive use of energy Due to the high temperature up to 1600 o C to melt the raw materials
bull It was estimated that each 1 kg of glass produce 169 MJ of waste heat
Energy consumption of the European glass
bull production of each ton of European glass consumed 78 GJ of energy (1 GJ=109 joule )
bull In 2007 The total energy consumption of the European glass industry was 352 PJ (1 PJ=1015 joule )
bull 418 J=1 calorie (1 calorie is the amount of energy needed to raise 1 gm of water 1 C)
ie 13-17 of the total industrial energy consumption in Europe
Energy consumption European glass
The emission rate of pollutants
The total CO2 emission for each 1 kg of glass
bull The production of each 1 kg of glass release 057 kg of CO2
bull The melting step only release 02 kg of CO2 for each 1 kg of glass
bull There is also emission of other greenhouse gases like SOx
The CO2 emission in Europe 2007
Effect of increasing CO2 and other green house gases
How much time glass needs to degrade
bull According to the chemical structure glass is not a biodegradable material
bull Glass needs more than a one million years to degrade
How much Waste Glass is found in the whole world
bull There is no clear information about the quantity of waste glass in the whole world due to the lack of information from different countries
bull According to the United Nations there was 14 million tons of waste glass in 2004
bull In USA 115 million tons of waste glass generated in 2010 with a recycling rate of 27 only (ie 84 million tons sent to landfills)
bull In Europe there was 41 million tons of waste glass in 2008 with a recycling rate of 60
In the next slide we can see the quantity of waste in Asia and the expectation rate of waste in 2025 based on the income of different
countries
bull For the high income countries in 1997 waste glass was about 595 million tons and will be 602 million tons in 2025
bull Middle income 680 000 tons in 1997 and 333 million tons in 2025
bull Low income 316 million tons in 1997 and 144 million tons in 2025
In Sweden Why its important to find a solution for glass waste
The Kingdom of Crystal Glass (Glasriket) in Smaringland
bull Witnessed the production of glass since 1742
bull According to the County administrative boards in Kalmar and Vaumlxjouml the glassworks in the region contain an estimated 310 tons of arsenic 19 tons of cadmium 1600 tons of lead and more than 130 000 m3 of waste glass
bull Recently the Swedenrsquos county administrative boards have mapped 20000 locations that are contaminated with hazardous materials for human and environment 10 of the 22 acute risks and dangerous locations are glassworks in Smaringland

How we can save raw materials Energy And reduces the emission
of the greenhouse gases
How we can reduce the quantities of waste glass which are already
found in landfills
Recycling of waste glass
bull Theoretically and due to the chemical structure of glass this material can be recycled without any limit
bull Each color of glass must be recycled with the same color
bull 5 grams of one color can contaminate 1 ton of another color
bull Broken and mixed color waste glass makes the recycling impossible sometimes because these materials cause a variation in the chemical composition of the recyclibale glass
What is the cullet
The cullet
bull Cullet is a crushed waste glass that is used for recycling
bull The cullet is often mixed with virgin glass materials to produce new glasses
Recycling glass saves 74 of the energy it takes to make glass from raw
materials and of course reduces the greenhouse gases emissions
bull Because the cullet melts at a lower temperature compared to that needed to make glass from the virgin raw materials
The energy saved from recycling of one glass bottle is equal to the energy needs to operate a 100-watt light bulb
for 4 hours
Recycling rate of container glass in Europe
Cement industry challenges
1 The intensive use of the earth natural resources as raw materials
bullEach ton of cement clinker consumes 17 tons of the earthrsquos natural resources as raw materials
Production rate only in China
2 Intensive use of energy
bullCement industry is considered one of the most energy intensive industries each 1 ton of cement needs 6 million BTUs of energy
Total production of cement and energy consumption in China only
3 The high emission of green house gases especially CO2
bullCement industry accounted for about 7 of the total worldrsquos CO2 emission and it is expected to increase by 50 within 2050
CO2 emission with time
How we can solve the problems of cement and glass industries
Using waste glass in the production of cement and concrete industries
Waste glass can be used as an aggregate for the production of
concrete
Or waste glass can be used as a replacement for cement itself
Benefits of Using 20 of Waste Glass as a Raw Material in Cement industry
bull 20 replacement of cement with waste glass will reduce the CO2emission of cement by 20 million tonsyr
bull 20 of cement replacement with waste glass will result in saving of 95 trillion BTUs of energy annually
bull 25 of cement replacement would be equivalent to about removing 15 of automobiles
Other benefits of using waste glass in cement industry
bull Using waste glass in cement industry will reduce the price of cement
bull Using waste glass in cement industry will reduces the environmental impact of the solid waste materials and helps to reduce the landfills spaces
bull The use of waste glass in cement industry will help in the save of the earth natural resources from depletion because of the intensive use of these natural raw materials in cement and glass industries
Other uses of waste glass
bull Masonry concrete blocks
bull Blocks pavement
Flooring
Foam glass
Glass wool
bull Used for thermal insulation
Can waste glass be a secondary resource to recover metal values
bull salt extraction process
The process is based on the extraction of metal values from the raw materials into a molten salt bath consisting of NaCl LiCl and KCl corresponding to the ternary eutectic composition and with AlCl3 dissolved in the salt melt acting as the chlorinating agent This is followed by the electrolysis of the salt bath in the same reactor The normal processing temperature is in the range 973 K (700 degC) to 1173 K (900 degC)
Principle of the Salt Extraction Process
Glass smelting technique
bull To reduce the metal oxides to metal by melting the glass with reactants such as carbon or aluminium In this process metal oxides form into metallic spheres and fall to the bottom of the glass melt

found in landfills
Recycling of waste glass
bull Theoretically and due to the chemical structure of glass this material can be recycled without any limit
bull Each color of glass must be recycled with the same color
bull 5 grams of one color can contaminate 1 ton of another color
bull Broken and mixed color waste glass makes the recycling impossible sometimes because these materials cause a variation in the chemical composition of the recyclibale glass
What is the cullet
The cullet
bull Cullet is a crushed waste glass that is used for recycling
bull The cullet is often mixed with virgin glass materials to produce new glasses
Recycling glass saves 74 of the energy it takes to make glass from raw
materials and of course reduces the greenhouse gases emissions
bull Because the cullet melts at a lower temperature compared to that needed to make glass from the virgin raw materials
The energy saved from recycling of one glass bottle is equal to the energy needs to operate a 100-watt light bulb
for 4 hours

The production rate of glass in the world
bull The world total production of glass was about 894 million tons in 2007
bull EU countries produced about 383 million tons in that year About 30 of the total production makes Europe the largest glass producer
bull The production rate is expected to increase due to the increase in the industrialization and the improvement in the standard of living
How much raw materials we need to produce 1 kg of glass
bull Each 1 kg of sheet glass needs 173 kg of raw materials and 015 m3 of water
While we need 12-13 kg of raw materials to produce 1 kg of container glass
How much energy we need to produce 1 kg
of glass
bull Glass industry is considered one of the most intensive use of energy Due to the high temperature up to 1600 o C to melt the raw materials
bull It was estimated that each 1 kg of glass produce 169 MJ of waste heat

How we can save raw materials Energy And reduces the emission
of the greenhouse gases
How we can reduce the quantities of waste glass which are already
found in landfills
Recycling of waste glass
bull Theoretically and due to the chemical structure of glass this material can be recycled without any limit
bull Each color of glass must be recycled with the same color
bull 5 grams of one color can contaminate 1 ton of another color
bull Broken and mixed color waste glass makes the recycling impossible sometimes because these materials cause a variation in the chemical composition of the recyclibale glass
What is the cullet
The cullet
bull Cullet is a crushed waste glass that is used for recycling
bull The cullet is often mixed with virgin glass materials to produce new glasses
Recycling glass saves 74 of the energy it takes to make glass from raw
materials and of course reduces the greenhouse gases emissions
bull Because the cullet melts at a lower temperature compared to that needed to make glass from the virgin raw materials
The energy saved from recycling of one glass bottle is equal to the energy needs to operate a 100-watt light bulb
for 4 hours
Recycling rate of container glass in Europe

bull 5 grams of one color can contaminate 1 ton of another color
bull Broken and mixed color waste glass makes the recycling impossible sometimes because these materials cause a variation in the chemical composition of the recyclibale glass
What is the cullet
The cullet
bull Cullet is a crushed waste glass that is used for recycling
bull The cullet is often mixed with virgin glass materials to produce new glasses
Recycling glass saves 74 of the energy it takes to make glass from raw
materials and of course reduces the greenhouse gases emissions
bull Because the cullet melts at a lower temperature compared to that needed to make glass from the virgin raw materials
The energy saved from recycling of one glass bottle is equal to the energy needs to operate a 100-watt light bulb
for 4 hours

The process is based on the extraction of metal values from the raw materials into a molten salt bath consisting of NaCl LiCl and KCl corresponding to the ternary eutectic composition and with AlCl3 dissolved in the salt melt acting as the chlorinating agent This is followed by the electrolysis of the salt bath in the same reactor The normal processing temperature is in the range 973 K (700 degC) to 1173 K (900 degC)
Principle of the Salt Extraction Process
Glass smelting technique
bull To reduce the metal oxides to metal by melting the glass with reactants such as carbon or aluminium In this process metal oxides form into metallic spheres and fall to the bottom of the glass melt

How we can save raw materials Energy And reduces the emission
of the greenhouse gases
How we can reduce the quantities of waste glass which are already
found in landfills
Recycling of waste glass
bull Theoretically and due to the chemical structure of glass this material can be recycled without any limit
bull Each color of glass must be recycled with the same color
bull 5 grams of one color can contaminate 1 ton of another color
bull Broken and mixed color waste glass makes the recycling impossible sometimes because these materials cause a variation in the chemical composition of the recyclibale glass
What is the cullet
The cullet
bull Cullet is a crushed waste glass that is used for recycling
bull The cullet is often mixed with virgin glass materials to produce new glasses
Recycling glass saves 74 of the energy it takes to make glass from raw
materials and of course reduces the greenhouse gases emissions
bull Because the cullet melts at a lower temperature compared to that needed to make glass from the virgin raw materials
The energy saved from recycling of one glass bottle is equal to the energy needs to operate a 100-watt light bulb
for 4 hours
Recycling rate of container glass in Europe

Cement industry challenges
1 The intensive use of the earth natural resources as raw materials
bullEach ton of cement clinker consumes 17 tons of the earthrsquos natural resources as raw materials
Production rate only in China
2 Intensive use of energy
bullCement industry is considered one of the most energy intensive industries each 1 ton of cement needs 6 million BTUs of energy
Total production of cement and energy consumption in China only
3 The high emission of green house gases especially CO2
bullCement industry accounted for about 7 of the total worldrsquos CO2 emission and it is expected to increase by 50 within 2050
CO2 emission with time
How we can solve the problems of cement and glass industries

bull salt extraction process
The process is based on the extraction of metal values from the raw materials into a molten salt bath consisting of NaCl LiCl and KCl corresponding to the ternary eutectic composition and with AlCl3 dissolved in the salt melt acting as the chlorinating agent This is followed by the electrolysis of the salt bath in the same reactor The normal processing temperature is in the range 973 K (700 degC) to 1173 K (900 degC)
Principle of the Salt Extraction Process
Glass smelting technique
bull To reduce the metal oxides to metal by melting the glass with reactants such as carbon or aluminium In this process metal oxides form into metallic spheres and fall to the bottom of the glass melt

bull salt extraction process
The process is based on the extraction of metal values from the raw materials into a molten salt bath consisting of NaCl LiCl and KCl corresponding to the ternary eutectic composition and with AlCl3 dissolved in the salt melt acting as the chlorinating agent This is followed by the electrolysis of the salt bath in the same reactor The normal processing temperature is in the range 973 K (700 degC) to 1173 K (900 degC)
Principle of the Salt Extraction Process
Glass smelting technique
bull To reduce the metal oxides to metal by melting the glass with reactants such as carbon or aluminium In this process metal oxides form into metallic spheres and fall to the bottom of the glass melt
