Polytetrafluoroethylene (PTFE), valued for its remarkable chemical and thermal resilience, resists conventional recycling due to its crystalline structure and high melting point. Here, the authors demonstrate a mechanochemical route to upcycle PTFE as a fluorinating reagent mediated by potassium metal.
