Materials manufacturer Covestro has signed a cooperation agreement with Chinese bottled water and beverage company Nongfu Spring and plastics recycling company Ausell to upcycle and reuse the 19-liter polycarbonate water barrels. Through this cooperation, the companies will further optimize the recycling efficiency of Nongfu Springâ€™s 19-liter polycarbonate barrels, improve the traceability and quality of recycled materials, and extend the life of barrels that are no longer in use. The signing ceremony was held today at Nongfu Springâ€™s headquarters in Hangzhou, China.
â€œAs the inventor of polycarbonate, Covestro has been focusing on developing a variety of recycling solutions for post-consumer polycarbonate. Polycarbonate is extremely valuable, so we are committed to working with partners in the value chain to enable upcycling of polycarbonate and thus foster a circular economy,â€ said Holly Lei, President of Covestro China. â€œCollaboration within the industry chain to facilitate recycling will improve the traceability and quality of materials, and all parties and society can benefit from it.â€
Bayer, of which Covestro arose from, invented polycarbonate in 1953. The engineering plastic is extremely robust and lightweight, has excellent heat resistance and can be easily molded. The transparent plastic is odorless, does not cause harm to the human body and meets the hygiene standards set by the US Food and Drug Administration and European Union health authorities. Polycarbonate is widely used across many industries, including mobility, construction, electrical, electronics and appliances, healthcare and LED lighting.
According to the agreement, Nongfu Spring plans to collect and recycle 1 million 19-liter polycarbonate barrels that are no longer in use every year. These barrels are later chopped, washed and re-pelletized by plastics recycling company Ausell. Covestro will then transform the processed plastic granules into high-performance recycled plastics for use in industries such as electronics, home appliances and automotive.
â€œThis cooperation will allow polycarbonate barrels in the packaged drinking water industry to be recycled, revived and restructured for use in the electronics, home appliances and automotive industries so as to promote the sustainable use of polycarbonate materials,â€ said Zhou Li, Secretary of the Board of Directors of Nongfu Spring. â€œNongfu Spring will continue to work with all partners in the recycling industry chain and we hope to promote the sustainable and healthy applications of plastic materials.â€
