Covestro invests in the circular economy. The German materials manufacturer is testing an innovative and environmentally friendly process for recycling saline process wastewater in plastics production. The pilot plant for the process is localized at the Krefeld-Uerdingen site in Germany. The new technology reduces the salt levels in waters such as the Rhine and conserves potable water resources. It is being used in the production of polycarbonate, a high-performance plastic required in many sectors, including automotive engineering, electronics and medical technology. The German Federal Ministry for the Environment has provided some 740,000 euro in funding to support the project as an outstanding example of how a closed-cycle approach can be put into practice in industry. The total cost of investment is around 3.7 million euro.
