In Pakistan municipal solid waste (MSW) is collected in roadside bins and Municipal Corporation collects it infrequently. Solid waste generation ranges between 0.6 to 0.8 Kg/capita/day and the waste generation growth rate is 2.4% per year. The amount of plastic waste in Pakistan is about 15% in the composition of domestic MSW. Most of the post consumer, plastic products are discarded and end up as mixed plastic municipal waste. The disposal of this waste has become a major social concern. Mixed plastic waste (MPW) recycling is still very much in its infancy. This paper deals exclusively with tertiary recycling by pyrolysis and catalytic cracking of plastics waste alone and by coprocessing with petroleum residue or heavy oils to fuels and petrochemical feedstock for further processing in existing refinery and petrochemical units.
