Covestro announces that it now offers a polycarbonate with a 90% recycled content of plastic from post-consumer waste (PCR) that can be used in consumer electronics, among other applications.

The carbon footprint of the new Makrolon PCR polycarbonate resin is 70% lower than that of a comparable fossil-based virgin plastic and is part of the CQ portfolio of circular solutions at Covestro. The company plans to initially offer this grade in the Asia-Pacific region.

"We are very proud of this breakthrough solution as it will enable our customers to achieve their sustainability goals faster. This is especially true for industries such as consumer electronics and audio and networking equipment manufacturers, which have ambitious sustainability goals of their own," said Lily Wang, Global Head of the Engineering Plastics segment at Covestro.

This type of plastic can achieve exceptional whiteness and highly saturated colors, which is typically a challenge for PCR plastics with high recycled content. This is made possible by selecting high-quality recyclates and optimizing the material composition during the compounding process.

Covestro now offers a PC with 90% recycled plastic from PCR that can be used in consumer electronics and other applications.

The PCR grade is manufactured with halogen-free flame retardants that meet performance requirements without increasing environmental impact. It also meets the highest V-0 rating of Underwriters Laboratories' UL 94 flammability standards.

Covestro's Bayblend FR3010 R75 polycarbonate blend is used, for example, in the ear cups of Danish brand Jabra's latest Evolve2 headset series for audio equipment and video conferencing systems. This type is made of 75% recycled material and has a 50% lower carbon footprint compared to its conventional fossil-based counterpart, but still meets performance requirements well.

To meet rising demand, Covestro is currently building a dedicated compounding plant for PCR polycarbonates at its integrated site in Shanghai. Once commissioned, which is scheduled for later this year, it will be able to supply more than 25,000 metric tons of high-quality PCR polycarbonates annually.

In addition to PCR grades produced through mechanical recycling, Covestro is also making progress with polycarbonates attributed with raw materials produced using a mass balance approach derived from bio waste and residual materials and certified to the internationally recognized ISCC PLUS standard.

The company now regularly supplies Makrolon RE polycarbonates with a renewable attributed raw material content of up to 89%. Selected products, including climate-neutral polycarbonates, are supplied with 100% renewable electricity under a TÜV-certified system.

Already at the end of 2021, Covestro supplied customers in Europe with the world's first climate-neutral polycarbonates. Also the RE series is part of the CQ portfolio of circular solutions at Covestro.

The mass-balanced products demonstrate an identical good quality and performance as fossil-based polycarbonates and offer an out-of-the-box solution for customers with a significantly lower carbon footprint.
