Intensive research is currently being conducted into modern and more climate-friendly processes in steel production. In an effort to find a solution that can be implemented in the short term, the steel producers thyssenkrupp Steel and Hüttenwerke Krupp Mannesmann are cooperating with the recycling company TSR Recycling GmbH & Co KG under the scientific leadership of VDEh-Betriebsforschungsinstitut GmbH. The REDERS project, Reduzierte CO2-Emissionen durch Erhöhung der Recyclingquote bei der Stahlherstellung, reduced CO2 emissions through increased recycling quota in the steelmaking process is to strengthen the recycling cycle of iron and steel, while reducing the CO2 emissions of thyssenkrupp Steel and Hüttenwerke Krupp Mannesmann. Funding in the amount of 6.4 million euros has now been granted for this circular economy project aimed at conserving resources as part of the Programm für rationelle Energieverwendung, regenerative Energien und Energiesparen, progres.nrw, Programmbereich Innovation, program for rational use of energy, renewable energies and energy saving program section Innovation. The funding by the state of NRW is closely linked to the North Rhine-Westphalia’s initiative IN4climate.NRW.

The innovative manufacturing process developed by TSR produces a novel certified product from conventional starting materials - i.e. consumer scrap which permits use in the blast furnace and an increase in the proportion of recycled material in the converter process. CO2 emissions can thus be significantly reduced by increasing the share of recycled material in the steelmaking process.

Through the use of the recycled product, the amount of injection coal and the coke consumption in the blast furnace can be reduced: The use of one tonne of the recycled product can thus save about one tonne of CO2. In the converter, it would be a reduction of 1.7 tonnes of CO2 per tonne of recycled material used. Thereby, the project complements the transformation paths pursued by thyssenkrupp Steel and HKM towards climate-neutral steel production.

It is expected that regular use of the recycled material produced with the new process will begin in the autumn of 2022.
