The "white pollution" produced by discarded plastics is one of the urgent environmental problems

Recently, the catalytic polymerization and engineering research group led by Wang Qinggang, a researcher at the Qingdao Institute of Bioenergy and Processes, Chinese Academy of Sciences, has developed a catalytic system for the controlled polymerization of lactones and the efficient depolymerization of polyesters (as shown in the picture)

Part of the research results have been applied for international PCT patents and Chinese invention patents, and published on ACS Sustainable Chemistry & Engineering with the title of Zn(HMDS) ₂ as a versatile transesterification catalyst for polyesters synthesis and degradation towards a circular materials economy approach.
