This unique book provides comprehensive and holistic information on the circular economy of plastics - products and their design for circularity, markets and producer responsibility, recovery of wastes and resource responsibility, and plastics manufacturing with circular feedstocks. The central part of the book is on circularity and circular feedstocks, embedded in a framework of chapters on the relevant properties of plastic as a material, its ecosystems and mass streams across Europe on the one hand and of chapters on Life Cycle Analysis and Product Carbon Footprint, on digitalisation, logistics, and standardization on the other hand. Comprehensive information is provided on relevant EU-regulation and on national regulation in Europe, too. A knowledge body contains information on relevant associations and networks, on recent studies on the topics mentioned, and an extensive glossary. Thus the book is a compendium of information on the dynamically evolving realm of the circular economy providing insight and clarity into complex and puzzling structures and positions. The book addresses professionals in a wide range of industries together with scholars and students in science and technology as wells as policy makers, authorities, and the media.
