Recycling Of Waste Polyurethane Has Become A Research Hotspot.

The problem of waste polyurethane recycling has become a research hotspot. Environmental protection is another major problem facing the rising polyurethane industry.

With the increasing use of polyurethane materials in the national economy and the increasing consumption, the recycling and reuse of polyurethane materials are attracting more and more attention.

The waste polyurethane mainly includes the corner waste, the mold overflow material, the polyurethane foam and elastomer in the scrap car, the refrigerator, the used shoes and the old PU leather, the spandex old clothes and so on.

There are three ways to recycle polyurethane at present: physical method, chemical method and energy law.

The recycling and utilization of waste polyurethane products, the EU first introduced the laws and regulations of waste plastics recycling of electrical products, the principle is who produces who recycles.

Our country should also speed up the recycling of polyurethane products, especially foam products.

The recycling of polyurethane is undoubtedly beneficial to environmental protection and resource utilization, but the main problem is whether recycling waste polyurethane has economic benefits.

Because of the large amount of polyurethane and the high price of raw materials in recent years, the market prospect of waste recycling is promising. However, the recycling methods used before are generally not strong in economy and can not be widely promoted. Therefore, developing an economical and feasible recycling method has become a hot topic in the industry.
