Abstract: Plastics are one of the major inventions of the modern era. It can be molded into different shapes and sizes on the basis of requirement. We cannot think of a life without plastic. The major component of making plastic is crude oil which is non-renewable resource .According to studies the crude oil consumption rate is increasing day by day and it is depleting considerably. The important disadvantage of plastics is treatment of plastic after consumption .Plastic contributes to major portion of municipal waste all over the world. Plastics are non-biodegradable substances which mean It will not undergo normal decomposition as biological matter. So plastic cannot be dumped into landfills or to water bodies. In the case of landfills, plastics will stay there without decomposing and ultimately leads to infertility of soil. And in the case of water bodies, the aquatic organisms eat these plastics misunderstanding as food and it will not digest in their stomach and as a result they dies. Major share of ocean pollution are deposition of post consumed plastics. Manufacturing as well as incineration of plastics causes air pollution which involves production dioxins and leads to deadly diseases like cancer, lung problems…Pyrolysis is a thermochemical decomposition of organic substances at elevated temperatures without the presence of oxygen and it involves phase change as well as chemical composition changes. Municipal waste composes of different types of plastics. In this study we analyze oil extraction from different types of plastics.
