At thyssenkrupp Steel’s recycling location in the Duisburg inland port, on the so-called scrap island Schrottinsel in Duisburg, the groundbreaking ceremony for the construction of a scrap processing plant by TSR Recycling GmbH took place. The processing plant is part of the REDERS project, Reduced CO2-Emissions through increased recycling quota in the steelmaking process, funded by the state of North Rhine-Westphalia in the amount of EUR 6.4 million, which marks another steps towards a reduction of CO2 emissions in the steel industry through the establishment of a recycling center for steel scrap. The project partners in this initiative of the circular economy aimed at conserving resources are TSR and thyssenkrupp Steel as well as Hüttenwerke Krupp Mannesmann GmbH and VDEh Betriebsforschungsinstitut. Through the use of innovative processes, the processing plant is to produce a high-quality recycled raw material TSR40 intended for use in the Duisburg blast furnaces of thyssenkrupp Steel. The use of steel scrap in the blast furnaces of thyssenkrupp requires special material properties of the recycled product. Automated charging of the blast furnace requires a material that is as homogeneous as possible in terms of size and contour, so that blockages during material transport can be ruled out. Moreover, there are exact requirements regarding analytical impurities as unwanted tramp elements cannot be separated in the subsequent steelmaking process. Both requirements are met in the new processing plant, which is equipped with a special shredder and separation technology with subsequent online analysis and documentation software. The use of this specially processed scrap product allows at the same time to reduce CO2 emissions since an increased quantity of metallic iron in the form of recycled raw materials leads to a reduced consumption of iron ore and carbon carriers coke & coal to produce an identical amount of steel. Besides the long-term transformation of production processes to climate-neutral steelmaking, a reduction in CO2 emissions can thus be achieved in the very short term by increasing the recycling quota. About 1 tonne of CO2 per tonne of recycled material can be avoided in the blast furnace. For the use of recycled products in the blast furnace allows a reduction of the CO2 intensity from 2.1 of 0.75 tonnes in balance sheet terms. This fact has been certified by TÜV Süd in accordance with the VERIsteel process and forms the basis for the thyssenkrupp Steel‘s CO2-reduced product bluemint® recycled. In the future, TSR’s processing plant will support the production of the bluemint® steel range by providing a high-quality recycled product. Once the plant is completed, up to 260,000 tonnes of bluemint recycled can be produced per year on this basis.
