Chemical recycling demonstrates effective depolymerization of polyurethane foams using diethyl carbonate, suggesting a safer alternative to phosgene.
Harmless chemical recycling of polyurethane foams: depolymerization with diethyl carbonate allows deep recovery of both constituting monomers, i.e. polyols and diisocyanates, without requiring phosgene as toxic and wasteful reagent.
