Abstract : Plastic is an indispensable part of our daily life. A plastic material is any of a wide range of synthetic or semi-synthetic organic solids that are moldable. They are usually synthetic, most commonly derived from petrochemicals, but many are partially natural. Its production and consumption has been rising very rapidly due to its wide range of application. There are two types of plastics: thermoplastics and thermosetting polymers. Thermoplastics are the plastics that do not undergo chemical change in their composition when heated and can be molded again and again. Thermosets can melt and take shape once; after they have solidified, they stay solid. In the thermosetting process, a chemical reaction occurs that is irreversible. Due to its non-biodegradable nature it cannot be easily disposed of. So, nowadays new technologies are being used to treat the waste plastic. One of such process is pyrolysis. This paper describes non catalytic pyrolysis of plastic wastes into useful gasoline range hydrocarbons. Under the pyrolysis and cracking conditions the plastic wastes can be decomposed into three fractions: gas, liquid and solid residue. Here the main consideration is the recovery of liquid products which are composed of higher boiling point hydrocarbons. The waste plastics consisting of high density polyethylene (HDPE) was pyrolyzed in this study. Pyrolysis appears to be a technique that is able to reduce a bulky, high polluting industrial waste while producing energy and/or valuable chemical compounds. The pyrolysis of plastic wastes produces a whole spectrum of hydrocarbons including paraffin, olefins, naphthalene and aromatics. By catalytic cracking more aromatics and naphtha in the range of C6-C8 which are valuable gasoline range hydrocarbons can be produced. This application is further combined with technologies of municipal plastic wastes collection, classification and pre-treatment at front end and product purification and testing at back end to determine the properties of the various products obtained.
