Plastic
» According to the Stanford University PSSI Recycling Center, if you recycle 1 ton of plastic, it saves up to 5,774 kilowatt-hours of energy.
» A study by the Harvard University shows that one of the most important benefits of plastic recycling is that it increases the shelf life of landfills, which have been predicted to become exhausted in around 20 years time.
» The most prominent benefit of recycling plastic is that it reduces the amount of metals required for its production.
» Plastic is manufactured from derivatives of crude oil. A Stanford Recycling Center study states that recycling 1 ton of plastic bottles saves 16.3 barrels of oil.
Glass
» The prime benefit is that glass is 100% recyclable, and can be recycled easily without any loss in its quality.
» According to Ohio Department of Natural Resources, if you recycle glass, it reduces air pollution by 20% and water pollution by 50%, eventually saving 68% of energy.
» Cullet, also called recycled glass, is used by glass manufactures on a large scale. Using cullet not only saves energy, but also reduces the manufacturing cost.
» By using cullet, the raw materials such as soda, limestone, and soda ash are conserved, and CO2 emissions are also cut down.
Paper
» If paper is regarded as waste, it goes into the landfills, and once it starts decomposing, it releases methane gas. The Environmental Protection Agency states that this greenhouse gas is 21 times more harmful than carbon dioxide.
» The usage of recycled paper reduces the amount of water, virgin paper, chemicals, and eventually the
