Recycling and Upgrading Utilization of Polymer Plastics†

Comprehensive Summary Due to the current situation of massive waste consumption and accumulation, the recycling and upgrading utilization of polymer materials is an effective technology to solve environmental pollution. In this work, the recycling and upgrading methods of polymers are summarized, and the latest progress in polymer upcycling is discussed from the perspective of upgrading materials. The common polymer recovery methods, including mechanical recovery, chemical recovery, biocatalysis, and photocatalytic recovery, are discussed based on their mechanism and industrialized application. The upgrading products of polymers are divided into monomers, fuels and fine chemicals. The challenges and prospects of polymer degradation technology are discussed.
