New method turns foam into higher value rubber and hard plastics — ScienceDaily

Researchers have developed a new method for upcycling polyurethane foams, the spongy material found in mattresses, insulation, furniture cushions and shoes. This process, developed by researchers at Northwestern University and the University of Minnesota, first involves mixing postconsumer polyurethane foam waste with a catalyst solution that allows the foam to become malleable. Next, the method […]
