Covestro Launches Major Energy Efficiency Project at Dormagen Site

Covestro has announced its largest energy efficiency project to date, aimed at significantly reducing energy consumption and carbon emissions at its Dormagen facility in Germany.

The company is investing a low double-digit million-euro sum in the installation of a new steam compressor that will lower Covestro’s energy consumption in Germany by around 2% annually compared with 2025 levels.

The project is expected to save a low three-digit gigawatt-hour volume of energy each year while cutting more than 40,000 tonnes of CO₂ emissions annually, equivalent to the emissions generated by a town of approximately 5,000 residents or around 20,000 cars.

The compressor will use heat pump technology to raise the temperature and pressure of steam produced during the manufacture of toluene diisocyanate (TDI), a key raw material for flexible polyurethane foams, so it can be reused in production processes instead of being released as waste heat.

The initiative forms part of Covestro’s broader strategy to achieve climate-neutral and circular production operations. The company stated that it had already reduced energy consumption by approximately 40% between 2005 and 2022 and is targeting a further 20% reduction in energy use per tonne of product by 2030 compared with 2020 levels. Construction is scheduled to commence later this year, with the new compressor expected to become operational by mid-2027.
