Visible light–triggered co-upcycling of polypropylene and polyethylene terephthalate using waste chlorinated solvents
The chemical incompatibility of mixed plastics poses a fundamental barrier to their circularity. Polypropylene (PP) and polyethylene terephthalate (PET), among the highest-volume manufactured polyolefin and polyester, are particularly difficult to process together due to their divergent structures and stabilities. Here...
