Selective and Sequential Catalytic Chemical Depolymerization and Upcycling of Mixed Plastics

https://pubs.acs.org/doi/10.1021/acsmacrolett.3c00751

"Here, we report a rationally designed #organometallic #catalytic system using earth-abundant metals that achieves Nylon-6 #depolymerization under mild and benign solvent-free conditions at unprecedented rates and selectivity. This process is effective for diverse commodity end-of-life articles such as fishing nets, carpets, clothing, and #plastic mixtures."
