![]() ![]() Polyurethane foam in automotive seating has been successfully recycled using regrind technology. ![]() These technologies open an emerging, effective and economic route for recycling polyurethane rigid foams and composite. The various recycling technologies for material and chemical recycling of PU materials have greatly contributed to improve the overall image regarding the recyclability of polyurethanes in recent years, by far the most important being regrinding and glycolysis. The various types of polyurethane waste products, consisting of either old recycled parts or production waste, are generally reduced to a more usable form, such as flakes, powder or pellets, depending on the particular type of polyurethane that is being recycled. Recent progress in the recycling and recovery of polyurethane and polyurethane composites is reviewed. ![]()
