    Abstract

    With increased production of plastics comes increased plastic material wastage, and thus new technologies are needed for waste refining. The development of chemical recycling technologies is motivated by two main needs, which are (i) the need to safely and efficiently process materials difficult to treat with mechanical recycling and (ii) the need to produce recycled materials of high quality. Chemical recycling encompasses a variety of technologies, examples of which are presented in this chapter, including, for example, thermochemical treatments and depolymerization. Basic operation principles, recent developments, and future prospects and application areas of the technologies are presented.
