Society produces more plastics than steel every year, and these pose major challenges in resource recycling. The principles of 3R are introduced and their application to plastics. Obtaining high-value products from recycling of the many different varieties of plastics in the waste stream is a major challenge for collection, separation and chemical processing. The main processes used for the major plastics (including PET, PVC composites etc.) are introduced and the legal and administrative framework for plastics recycling in Japan described. For instance, PET can be recycled as raw material for reprocessing PET, but other types of plastics pose major challenges and are often recycled for only low value uses such as a source of heat. This chapter looks at current approaches to recycling plastics and how it may be possible to convert them into higher-value raw materials.
