Prospect and current status of recycling waste plastics and technology for converting them into oil in China

In the paper, the authors present the current situation of recycling waste plastics and technology of converting waste plastics into oil in China. The process of pyrolysis and pyrolysis-catalytic upgrade method has been evaluated in terms of technology and economics. The conditions of a plant, that is to be constructed for converting waste plastics to oil, such as collecting system, transportation distance of waste plastics, sorting method and controlling over secondary pollution, are investigated. In addition, the commercialization and area of research on this technology in China are proposed.
