| Abstract: | The recycling processes and progress of polyurethane (especially PU foam) scrap are reviewed. The main recycling methods of PU include: binding of soft foam waste to form rebinded foam, heat pressing forming of the scraped PU, using the pulverized foam as filler, and decompose the scraps into recycling polyols by glycolysis, amine decomposing or hydrolysis, the recovered polyols can be reused to foaming. |
