Polyurethane chemistry is complex, but the basics are relatively easy to understand. Polyurethanes are formed by reacting a polyol with a diisocyanate or a polymeric isocyanate in the presence of suitable catalysts and additives.

Hi, polyurethane can be recycled in two major ways: 1, by rebonding the polyurethane crumbs using hydraulic press and 2, by converting the poyurethane into powder and use it as filler in new production. there are other technical things to know about polyurethane recycling but this answers the question.
