Chemical recycling of PET is highly desirable but currently less economical due to challenges such as energy intensive depolymerization.  In this lecture, I will describe the rapid chemical upcycling of PET via multiple creative approaches without using any organic solvent. We have been able to achieve 100% depolymerization in less than 1 hour at 160C, which, compared to the traditional methods, will take place 4 hours. This 4 fold increase in the polymerization of PET will offer new energy to the chemical recycling of PET.
