Closed-loop recycling of semi-aromatic polyesters upcycled from poly(ethylene terephthalate


Via selective deconstruction (by protic ionic salts), post-consumer plastic waste was converted into functional molecules that can serve as building blocks for new polymer materials with built-in closed-loop recyclability.

This new strategy shows that it is possible to use waste plastic as a feedstock to prepare useful molecules beyond the polymer’s component monomers, making the development of novel, upcycled circular plastics possible.
