The Recycling Of Plastic Waste Environmental Sciences Essay
The Recycling Of Plastic Waste Environmental Sciences Essay When you think about the huge amounts of plastics we produce and the problems that can occur when we try to Disposal of plastic, it makes sense to reuse or recycle what we can. Recycling: means making new things from items that have been used and are not need any more. Steps to recycling First, depolymerization is the step of transfer a polymer in a mixture of monomers. Second, thermal depolymerization is a depolymerization step using hydrous pyrolysis for the reduction of complex organic materials (often waste products of various sorts, often biomass and plastic) in a light crude oil.Third, the heat compression process have taken all unsorted, cleaned plastic in all forms, from soft plastic bags to hard industrial waste. The Applications in plastics tybes. (PET) are recycled to reuse the material out of which they are made and to reduce the amount of waste going to landfills. (PVC) is a thermoplastic polymer. (HDPE) The most-often recycled plastic. (HDPE) came from petroleum. (Other plastics)The white plastic foam peanuts used as packing material are often accepted by shipping stores for use it again.Finlly Example Items Recycling,Recycle Plastic Bags. Recycle Plastic Coat Hangers. Recycle Plastic Bottles .Recycle All Other Plastic Waste. The Effect of Recycling Plastics on the Environment # Resource Conservation Recycling plastic bottles assists to conserve natural resources, specially oil, that is nonrenewable natural resource obtainable only in limited provide recycling one ton of plastic can conserves around 3.8 barrels of oil according to the Environmental Protection Agency . 2.12 millions of plastic was recycled in 2008 which is equivalent to approximately 7.6 million barrels of oil. # Energy Conservation. The process of finding new materials from existing materials need much less energy than what is needed for rare materials. Recycling one pound of the most common plastic used in water bottles called polyethylene terephthalate (PET) can conserve around 12,000 British thermal units of heat energy according to the Environmental Protection Agency . the process of recycle needs less energy by two- third than usual manufacturing . which help in reducing the damage of the usual power grid. That depend on burning fossil fuels. # Reduced Greenhouse Gas Emissions The process of producing plastic is able to increase the greenhouse gasses in air like carbon dioxide. Which is known as a major reason of global warming . because recycling plastic require less energy and fossil fuels it result in reducing greenhouse gas revival . The Environmental Protection Agency foredoomed that each family can help to reduce its production of carbon dioxide by the average of 340 pounds yearly . just by reuse the plastic things # Decreased Pollution besides reducing greenhouse gasses . recycled plastic can decrease the amount of pollutants in air and water . in addition many of landfill operations will burn the plastic bottles to keep waste that is able to secreted toxic pollutants and other materials that irritants into the atmosphere . the plastic resin is useful to produce water bottles. Besides it contain unsafe chemicals Challenges of recycling Recycled the Plastics have a low entropy of mixing. A macromolecule of plastic interacts with its environment along its entire length. Also In most places, plastics are collected for recycling. It is not easy to recycle plastics because the different kinds of plastic must first be sorted out. Mixed plastic connot be used for recycling.In addaion, some people donà ¢Ã¢â ¬Ã¢â ¢t suport gaverment so they didnà ¢Ã¢â ¬Ã¢â ¢t put kind of plastic in the right place!!. In Germany and some parts of the United stats, you pay a deposit when you buy a full plastic bottle. When you take your empty plastic bottle back to the shop, you get the deposit back. This encourages people to return their emptyplastic bottles and not just throw them away. The shops then return the bottles to the company that made them for refilling. Another solution to reduce using of plastic Many scientists and governments are working together to find ways to stop using plastic. In Bangladesh the government prohibited the plastic bags completely. In 2002 Ireland imposed taxes for using plastic bags about 0.15 EUR per bag that helped to reduce the usage of plastic bags by 90 percent .besides , they gain 1 million dollar as a revenue. But as individual we can take the lead to reduce usage of plastic by several steps such as: we can use reusable bags which have a various shapes, designs and sizes, when you donà ¢Ã¢â ¬Ã¢â ¢t use it you can rolled and put it in your pocket. Another way you can use reusable water bottles which made of recycled materials that can last for a long time and be recycled once again also we can use glass bottles instead of plastic bottles which is reusable. Also the number of Disposable Diapers used nowadays is very huge, and it cost around $300 million yearly to decompose single use diapers . so families can use for their kids Disposable Diaper s that made of wood base instead of the once with plastic base because it is going to decompose later so it will not cause environmental problems and it cost less than the plastic once. However, good cooperation between the people and government and the countries will lead to better results . Conclusion This report is concerned with the complex question of dealing with plastic waste. There are dozens of different plastics in common use, and many products are made from a mixture of these. However , people dont really care about throwing plastics away as they are not expensive. The Previous pages introduced and discussed ideas such as source reduction of waste, degradability of plastic, and the impact on environment and human ,which all inter-relate with the central issue of plastic pollution. In addition, the report provided overview of the facts and issues involved, together with examples from around the world which demonstrate how progress is being made in effective waste management and production of brand new plastics is less cost. It must be emphasized that plastic waste recycling and management are not merely the concern of large-scale schemes and companies. Every individual one of us can take action to deal effectively with plastic waste in our lives, and in this small way make an essential contribution towards improving our environment by put our own selfish needs before the needs of everything around us now and the lives of future generations.
