Covestro has developed an innovative technology that allows using CO2 as raw material for the production of chemical building blocks for high-quality plastics. The most widely known of the numerous possible applications for these building blocks, called polyols, are polyurethane flexible foams used for mattresses and furniture. The new polyols, commercially available under the trade name cardyonTM contain up to 20% CO2, and have comparable or even better properties than the conventional ones, made of crude oil. They are being produced in Covestro’s new facility in Dormagen, Germany, since 2016.
