Recycling waste plastics including polypropylene, polyethylene, polyethylene terephthalate, polystyrene, etc, is a very important scientific, social and economic topic. Despite significant advances in recent years, approximately 400 million tons of waste plastics are still disposed by landfill. This is obviously not an effective solution due to plastic’s non-biodegradable character. Aside from mechanical recycling, which turns waste plastics into new products, and thermal recycling, which releases the thermal energy through combustion of waste plastics, chemical recycling converts waste plastics into feedstock for chemicals/materials/fuels production. This article reviews previous work on the pyrolysis and catalytic decomposition route that converted plastics into carbon-based materials, which exhibited extraordinary physical and chemical properties. However, their production processes are both resource and energy-intensive. Therefore, recycling technologies for waste plastics are still at an early stage and more innovation in waste plastic recycling is needed.


Key words: waste plastics, converting, catalytic decomposition, carbon based materials
