Covestro, a leading global polymer manufacturer, is focusing on innovative recycling as one of the key levers to achieve a circular economy. China is one of the most important producing countries for plastics in the world and is taking various measures to promote domestic plastics recycling while banning or restricting single-use plastics. Working with a consortium of partners from the recycling value chain in China, Covestro contributed to the recent development of national standards for recycled polycarbonate, a highly durable and versatile engineering plastic with high recycled value.

Unified quality specifications for recycled polycarbonates from post-consumer and post-industrial waste

For use from July 13, 2021, specifications on the quality and property requirements for recycled polycarbonates from post-consumer and post-industrial waste have been developed in the Guobiao (GB) standards. In addition, standards for testing methods, packaging, transportation and storage of these recycled materials will be introduced to ensure proper handling throughout the value chain.

"Creating uniform standards is essential to improve the polycarbonate recycling value chain while promoting the use of these recycled materials in downstream applications," said Kayla Wu, global program manager of mechanical recycling, Covestro's Engineering Plastics segment. "As a global leader in polycarbonate sustainability solutions, Covestro is proud to contribute our expertise to the development of the national standards while living up to our vision of full circularity."

Improving quality and traceability in recycling

To turn polycarbonate waste into high-quality recyclates, the materials need to go through many quality control steps and specifications and require close collaboration along the value chain. End-of-life polycarbonate products are first collected, sorted, shredded and cleaned before being reprocessed into pellets by recycling companies. Covestro then blends these recyclates with virgin polycarbonates to produce high-quality post-consumer recycled materials to be used again in new products like laptops, copiers, printers and other electronic devices.

In its collaboration with Chinese beverage producer Nongfu Spring and recycling company Ausell, Covestro has gone one step further in closing the material loop with new business models. Through this collaboration, the companies have further optimized the recycling efficiency of Nongfu Spring's 19-liter polycarbonate barrels and improved the traceability and quality of recycled materials. Building on this success, Covestro plans to further look into other waste streams such as e-waste to help the electrical and electronics industry build a circular economy.

"Improving the quality and standardization of recycled plastics is key to the transition to a Circular Economy. The Chinese GB standards for polycarbonate recyclates will create even more transparency regarding the quality of recycled polycarbonates, thus boosting market demand," says Daner Xue, product technology expert of Covestro's Engineering Plastics segment.

Covestro, FILK Freiberg, and OUT e.V. develop flexible, conductive polymer smart textile system

As the smart textiles market continues to grow across healthcare, personal protection, sportswear, and automotive applications, developers are seeking new ways to integrate electronic functionality directly into textiles, without the rigidity and complexity of conventional wiring. To address this challenge, FILK Freiberg Institute, an independent research institution with expertise in polymer coatings for textile applications, collaborated with Optotransmitter-Umweltschutz-Technologie (OUT) e.V. The joint project, funded under the German Industrielle Gemeinschaftsforschung (IGF) program of the Bundesministerium für Wirtschaft und Energie (BMWE), focused on developing flexible, conductive polymer surfaces for next-generation smart textiles.

Covestro to exhibit solutions for a more sustainable and productive textile industry at Techtextil 2026

Covestro will present a broad portfolio of material innovations for textile coatings, adhesive films and thermoplastic polyurethanes (TPUs) at Techtextil 2026 (Hall 11.0, Booth C79). The exhibits will demonstrate how advanced solutions can enhance durability, recyclability and manufacturing efficiency across applications such as automotive, infrastructure, protective apparel and sportswear. A particular focus will be on more sustainable coating technologies, including antimicrobial systems based on INSQIN® in combination with AGXX from Heraeus Precious Metals, as well as the integration of Pontacol® thermoplastic adhesive films into Covestro’s offering.

Covestro showcases monomaterial concept in autonomous SUE People Mover

UE | STUDIOS has unveiled the fully autonomous electric minibus “Self-driving Urban E-Shuttle” (SUE), placing strong emphasis on sustainable material design. Developed within a project funded by the Federal Ministry for Economic Affairs and Energy (BMWE) and the European Union, the vehicle will begin public road testing this year. At the core of the concept is the consistent use of recyclable monomaterials to improve circularity at end of life.

Covestro and Heraeus Precious Metals collaborate to enable safer, more sustainable antimicrobial textile coatings

Laboratory tests reveal that AGXX antimicrobial surface technology from Heraeus Precious Metals is fully compatible with Impranil® PU dispersions which are part of the waterborne INSQIN® textile coating technology from Covestro, paving the way for more sustainable antimicrobial textile coatings. This discovery comes at a key moment for the textile coatings industry. As the sharing economy continues to grow, more people are coming into regular contact with high-use surfaces, creating ideal conditions for bacteria, viruses, and other microorganisms to thrive.

EU ban on destroying unsold clothing and footwear now in force

The European Union's ban on the destruction of unsold clothing, clothing accessories and footwear has entered into force. Since July 19, 2026, large companies across the EU have been prohibited from destroying unsold textile products, while medium-sized companies will be required to comply with the same rules from 2030.
