Knauer, Katrina M.

Global plastic production is at an all-time high and shows little signs of slowing down. Less than 10% of all plastic produced is recycled, with approximately 90% entering landfills, incinerators, and oceans. This has led to a rapid accumulation of single-use plastic waste across the planet. Mechanical recycling has been executed at the industrial level to manage plastic waste for decades. However, mechanically recycled plastic products are significantly limited by contamination and low performance. Chemical recycling technologies offer another pathway for achieving plastic circularity. This chapter highlights the current state-of-the-art chemical recycling technologies for plastic decomposition into monomers, fuels, or other petrochemical feedstocks. A brief description of recyclability of plastics and the waste sorting process is provided followed by a high-level overview of chemical recycling technologies. Products, key barriers, and limitations are also discussed as well as a brief overview of techno-economics.
