New electric arc furnace slag for CO₂-reduced cement

Ulrich Grethe, head of steel production at Salzgitter AG, regards the project, which is headed up for Salzgitter by the research company Salzgitter Mannesmann Forschung GmbH, as making an important contribution towards orienting the Salzgitter Group toward the circular economy: “We intend to use the results of the project to support us in ensuring that the finite resources consumed in the production of steel in future continue to be applied as effectively as possible on the principle of circularity in a manner that minimizes the employment of additional resources.”

For Thomas Reiche, too, as Managing Director of the FEhS Institute, the research project represents another important contribution to the sustainable circular economy: “The second part of the current World Climate Report that was recently published shows that we must intensify our research now in order to employ innovative technologies to further reduce CO₂ emissions while at the same time strengthening the economy! With “DRI-EOS”, together with our partners we are aiming to put in place the conditions necessary to allow the high-value byproducts of the steel industry to continue to be used in future as resource-conserving low-CO₂ building materials in the cement and concrete industry.”
