Upcycling may help remedy the roughly 450 million tons of plastic discarded worldwide annually, of which only nine per cent ...

One process, called ring-opening metathesis polymerization, opens carbon rings and elongates them into chains. The other process, called cross metathesis, inserts chains of polymer subunits from ...

The researchers utilized two metathesis-based methods to upcycle plastic waste. In ring-opening metathesis polymerization, carbon rings open and elongate into chains. In cross-metathesis, polymer ...
