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.
