Abstract This review presents a comprehensive description of the current pathways for recycling of polymers, via both mechanical and chemical recycling.
The principles of these recycling pathways are framed against current-day industrial reality, by discussing predominant industrial technologies, design strategies and recycling examples of specific waste streams.
Starting with an overview on types of solid plastic waste SPW and their origins, the manuscript continues with a discussion on the different valorisation options for SPW.
The section on mechanical recycling contains an overview of current sorting technologies, specific challenges for mechanical recycling such as thermo-mechanical or lifetime degradation and the immiscibility of polymer blends. It also includes some industrial examples such as polyethylene terephthalate PET recycling, and SPW from post-consumer packaging, end-of-life vehicles or electr on ic devices.
A separate section is dedicated to the relationship between design and recycling, emphasizing the role of concepts such as Design from Recycling. The section on chemical recycling collects a state-of-the-art on techniques such as chemolysis, pyrolysis, fluid catalytic cracking, hydrogen techniques and gasification.
Additionally, this review discusses the main challenges and some potential remedies to these recycling strategies and ground them in the relevant polymer science, thus providing an academic angle as well as an applied one.
