Polyurethane recycling!

On the 19th, when I walked into Hejian Tenglong Brilliant Renewable Resources Utilization .

Cheng Jinglong, chairman of the company, said that through technological innovation, the company transformed the waste thermal insulation material polyurethane into a new building material - dry-mix composite lightweight aggregate concrete, and successfully applied for an invention pate.

Polyurethane is a common chemical material in the thermal insulation industry, mainly used in daily fresh food preservation packaging and home applianc.

Seeing the business opportunities, Cheng Jinglong founded the first domestic enterprise to recycle waste polyuretha.

Because the products produced have many advantages such as light weight, environmental protection, heat preservation, sound insulation, fire prevention, and no radioactivity, they have been used in Beijing's tallest building "China Zun", Beijing's new airport and Beijing city sub-center construction related projec.

Pan Yonggang, vice president and secretary general of the China Association of Renewable Resources Utilization, praised Cheng Jinglong for "turning waste into treasure and solving the major environmental protection problem in the country" after his on-site inspection, and actively contacted more than 100 companies to supply him with dismantling waste from old refrigerato.

Today, Cheng Jinglong has set up a research and development team to continuously improve the process, improve product quality and production efficien.

At present, the 500,000-cubic-meter polyurethane light aggregate project invested by Tenglong in Ningxia has been completed and put into operation this ye.
