Experimental study demonstrates glycolysis of poly(ethylene terephthalate) into monomer units using metal-free choline-based ionic liquids, suggesting potential for closed-loop plastic recycling.
Glycolysis of PET is a prospective way for degradation of PET to its monomer bis(hydroxyethyl)terephthalate (BHET) which can be polymerized again to form new qualified PET materials, and hence provides possibilities for a permanent loop recycling.
