Covestro launches polycarbonates for high purity applications

Joint development with Neste and Borealis

  • By ICN Bureau | April 23, 2024

Covestro introduces a range of polycarbonates based on chemically recycled, attributed material from post-consumer waste via mass balance for the first time: Makrolon RP at Chinaplas 2024.

In connection with its complete alignment to the circular economy, Covestro relies, among other things, on intensive collaboration with partners. For this project, the company is cooperating with two suppliers, Neste and Borealis, on the developments and for its own supply of the corresponding raw materials.

Initial market engagement with automotive brand owners for a serial application of a high-purity polycarbonate is promising, it would represent having a transparent polycarbonate attributed with chemically recycled raw materials.

"We are very excited to expand our existing portfolio of more sustainable polycarbonates with this new product range, which marks another milestone in building the circular economy," explains Lily Wang, Global Head of the Engineering Plastics Business Entity at Covestro.

"Together with our partners, we are already helping to conserve fossil resources and to give a second life to existing waste streams. We also support our customers in achieving their sustainability goals by providing materials that meet the highest purity standards."

The RP series offers identical quality as incumbent fossil grades and belong to Covestro's CQ family. The company uses this suffix to identify products that contain at least 25 percent alternative raw materials. At certain sites, such as Krefeld-Uerdingen in Germany, the plastics in the new range are also produced exclusively using renewable electricity.

The input for Makrolon RP is provided by Neste and Borealis: Neste provides high-quality recycled feedstock for new polymers, which is then turned into phenol and acetone by Borealis before it finds its way to Covestro’s site to produce Makrolon RP.

"Through chemical recycling, we can enable recycled content even for the most demanding applications," says Jeroen Verhoeven, Vice President Value Chain Development for Neste’s polymers and chemicals business. "Therewith, we can help companies across various sectors to achieve their recycling-related targets – and we are excited to see Covestro put it into motion."

"Borealis is very happy to support Covestro in this important initiative – helping to provide credible sustainable solutions and demonstrating the importance of value chain cooperation to give new value to waste," says Thomas Van De Velde, Borealis Senior Vice President Base Chemicals.

In addition to applications in the automotive industry, Covestro also wants to address other key industries such as the electrical & electronics and the healthcare industry. The aim is to manufacture high-quality and durable products with chemically recycled attributed feedstocks. At the end of a long usage phase, the plastics can still achieve a "third product life" through mechanical recycling and the further development of chemical recycling technologies.
