Evonik and Uniper launched the Technical Options for Thermal Energy Recovery (TORTE) project as one of the first phases of Evonik’s ‘Herne Green Deal’ to sustainably transform the Herne chemical site. The TORTE project will recover industrial waste heat from isophorone production and transfer it into the district heating network of around 1,000 homes in the Ruhr region.
To recover this industrial low-temperature waste heat, Uniper has installed an on-site heat pump to feed up to 1.5 megawatts of heat into the district heating network to supply local customers. This sustainably recovered heat from the Herne site will help Uniper reduce its emissions by 1,750 tons of CO2 per year. The project also supports Evonik’s sustainability ambitions to reduce carbon emissions and its use of fossil resources at its sites.
“This is only the first part of Evonik's sustainability journey at Herne. Our long-term ambition for the site is to run completely independent of fossil fuels - including the elimination of fossil-based raw materials from our production and reduce our carbon footprint,” said Christian Schmidt, head of the crosslinkers business line. “By focusing on our footprint and the handprint of our products we’re supporting our customers in meeting their CO2 emission and performance requirements. We achieve this by using renewable raw materials to develop new lower fossil carbon-based solutions such as our next generation IP, IPD, and IPDI eCO products, which help to shape a more sustainable future.”
The TORTE project was awarded first prize in the German Chemical Industry Association’s (VCI) "Responsible Care Initiative" for its sustainable and economical use of energy. The judges regarded the initiative in Herne as a benchmark for the holistic sustainable transformation of a chemical site towards green production and environmental protection.
“Optimizing production and reducing emissions by capturing industrial waste heat energy and reusing it, has long been an objective for the chemical industry,” said Dr. Rainer Stahl, site manager, Evonik, Herne. "Making a sustainable contribution to the municipal heat supply in our local community with waste heat can turn the Herne site into a shining example for sustainable chemical production.”
