Metal-Free Catalytic Upcycling of Waste Plastics into Value-Added Chemicals.

Caption

This diagram illustrates the process of upcycling waste plastics, including various polyesters (PET, PEF, PEA, PES, PLA) and polycarbonates (PC, PPC), using ionic liquid catalysts. The method involves the formation of hydrogen bonds between the ionic liquid and reactants, facilitating the transformation of PET into valuable chemicals such as dimethyl terephthalate (DMT) and ethylene carbonate (EC). The process efficiently depolymerizes PET and other plastics, offering a sustainable approach to plastic recycling and contributing to a circular economy.
