Abstracts: Waste plastics from municipal solid waste were collected. It was be sorted based on the types like (HDPE, LDPE, PVC etc.) They were graded into nearly uniform size by crusher, cutter & shredder. The graded feed was heated just to melt it so that extraneous impurities such as hard metal, clay, sand, glass etc settles in the bottom of the melter, which was removed periodically. The gaseous product during melting can be either dissolved in suitable solvent or incinerated to product heat. The modern plastic along with catalyst is sent to reactor, which is maintained at temperature between 350-600 *C and atmospheric pressure. The vapour which comes out of the reactor can be distilled to obtain different product are characterized for their usefulness. The various properties of the products obtained were than tested & compared with the actual values for petroleum range products.
