Abstract

The US has a serious plastic problem. It generates more plastic waste than any other country in the world, according to the Organisation for Economic Co-operation and Development (OECD). Plastic production is expected to increase dramatically, with the amount of plastic waste produced globally on track to almost triple by 2060. Recently chemical recycling has emerged as a potential solution to this problem. Chemical recycling is a broad term used to describe a range of technologies which the petrochemical sector claims can recycle plastic that is traditionally difficult to deal with mechanically. The main processes in chemical recycling are pyrolysis, gasification, solvent-based processes and chemical depolymerisation. The article looks at if chemical recycling is indeed the solution to the plastic pollution problem or are petrochemical companies overpromising on what the technology can deliver.
