Polyvinyl chloride (PVC) is challenging to recycle owing to the formation of hydrochloric acid during depolymerization at high temperatures. Now, a method for upcycling PVC that relies on its intrinsic reactivity in a low-intensity electrochemical process is reported, which can be exploited to chlorinate arenes.
