As the demand for stainless steel continues to rise, a responsible and efficient use of limited global resources is becoming increasingly important. One option for steelmakers to save greenhouse gases is to produce new stainless steel from high-quality secondary raw material blends instead of primary raw materials. Secondary raw materials are upgraded by combining differently alloyed stainless steel scrap to produce blends. These blends being in accordance with the technical specifications needed are used in steel mills as the main inputs in an electric arc furnace process. To a small extent, ferroalloys can be used for analytical fine-tuning. As early as 2010, Fraunhofer UMSICHT researchers determined a savings potential of more than 4.5 t CO2 per ton of blend on behalf of the Oryx Stainless Group. More recent calculations by the UMSICHT team even come to savings of over 6.7 t CO2 per ton of blend for the reference year 2021. The results show: The recycling of stainless steel scrap has great potential to save greenhouse gases. In the project, the UMSICHT researchers have now calculated the greenhouse gas balance of the recycling of stainless steel from the Oryx Stainless Group at the Dordrecht and Mülheim an der Ruhr sites, analogous to the study structure of 2010, for the reference year 2021. The results show that compared with the calculation at that time, the greenhouse gas savings continue to increase. A corresponding study for the site in Thailand is in progress at UMSICHT. Total savings by the Oryx Stainless Group at the two sites in 2021 amount to around 3,015,000 t CO2 –eq, approximately one million metric tons CO2 eq. more than in 2009 (2,026,000 t CO2 eq.). One reason is the comparatively higher output volume. The average weighted savings have also increased to 6.7 t CO2 eq./t blend in 2021. Thus, the results also retroactively show larger savings for the year 2009. Founded in 1990, the Oryx Stainless Group, with its parent company Oryx Stainless Holding, is one of the world's leading trade organisations for raw materials in the production of high quality stainless steels. The focus of the company's business activities is on the handling and processing of stainless steel scrap into Oryx Stainless Blends. These secondary raw material blends, individually fine tuned for each stainless steel producer replace, above all, primary raw materials.
