These comprise mostly biomass but also innovate technologies like the use of CO2 to make polymers for coatings and other resins. Covestro has already commercialized a polyol made from CO2 for the production of polyurethanes. The polyol is produced at a facility at Dormagen, near Cologne, Germany, which uses CO2 from the waste stream of a neighboring coal-fired power plant. "By using our CO2 technology for the synthesis of polyurethane raw materials, (we) have begun to close the carbon cycle in plastics production," said Hermann-Josef Doerholt, Covestro's polyurethanes sales manager in Europe. The company is also looking to establish bio-based value chains in chemicals as well. It has developed a technology for making the polyurethane precursor aniline from vegetable raw materials.
