Abstract
Waste plastics are creating environmental problems and occupying large amount of landfill. PVC waste is
generating ~10 % and PET ~8% from total waste plastics. Catalytic degradation of polyvinyl chloride and
polyethylene terephthalate mixture to petrochemical recovery at temperature ranges from 120-420 ºC using
aluminum oxide and activated carbon. PET sample of 75 g and PVC sample of 25 g, total raw materials of 100 g
was used in this experiment. Aluminum oxide of 5% (5g) as a catalyst and activated carbon of 5% (5g) was used.
Laboratory batch process experiment was conducted under laboratory fume hood without vacuum system. Product
fuel density is 0.85 g/ml. PVC and PET mixture to fuel production conversion rate is 42.9 % including liquid
product and gas product. Product fuel was analyzed by using Perkin Elmer Gas Chromatography and Mass
Spectrometer (GC/MS) and carbon chain detected C

. Present technology can convert all PVC and PET to
valuable fuel energy using catalytic degradation process. This process can remove PVC and PET waste plastic
problems from environment and convert them into valuable petrochemical energy. Copyright © IJRETR, all right

Introduction
Nowadays plastic consumption is more than ever increasing. Annual consumption of plastics in Occidental Europe
is about 60 million tons, of which about 40% are used in packing and packaging applications, which in a very short
period are converted into wastes, yielding about 15 million tons of such wastes per year [1]. At present, in Europe,
about 50% of the annually generated plastic wastes are valorized, 60% by incineration with energy recovery and
about 40% by recycling. Most of the recycled plastics are mechanically recycled, while less than 1% is chemically
recycled [1]. Municipal waste plastic represents about 8 wt% of the municipal solid waste and it generally consists
