What is Recycling Polyurethane Foam via Glycolysis about?

This research explores the recycling of polyurethane flexible foam (PUF) through glycolysis using Zn/Sn/Al hydrotalcites as a heterogeneous catalyst. The optimal reaction conditions for polyol recovery were identified, achieving a PUF/DEG mass ratio of 1.5 and a reaction time of 3 hours. The recovered polyol was characterized and utilized as a partial replacement for virgin polyols in new PUF synthesis, demonstrating its potential for sustainable recycling practices.
