thyssenkrupp MillServices & Systems receives QUBA quality seal for steel mill slag

In Germany, the construction sector is responsible for 36% of greenhouse gas emissions, 50% of raw material extraction and 35% of waste generation. The circular economy is an important lever for achieving climate neutrality[1]. Circular raw materials, such as steel mill slag, are of particular importance. thyssenkrupp MillServices & Systems has set itself the goal of going beyond the legal requirements and has successfully completed the QUBA certification for its two sites in Brandenburg. The QUBA (Qualitätssicherung Sekundärbaustoffe GmbH) seal of approval certifies the tested, quality-monitored and certified steel mill slag throughout Germany. It also guarantees the implementation of and compliance with the requirements of the German Substitute Building Materials Ordinance (English for “Ersatzbaustoffverordnung”).

thyssenkrupp MillServices & Systems is the second slag processor in Germany and the only company in Brandenburg to receive this certificate. The certificate confirms the company's consistent claim to supply high-quality products while complying with the nationwide environmental standards of the German Substitute Building Materials Ordinance. The Brandenburg an der Havel and Hennigsdorf sites ensure that all slag products always meet the required standards through in-house production control in the company's own laboratory.

Dr. Michael Dohlen, Head of Research & Development / Quality Assurance at thyssenkrupp MillServices & Systems: "The quality seal recognizes the high quality that thyssenkrupp MillServices & Systems applies in the production and processing of steel mill slag. We are thus making an important contribution to the changeover in raw materials, as electric furnace slag is suitable for many applications in technical structures in accordance with the German Substitute Building Materials Ordinance.”

The company pursues a holistic sustainability strategy. An important component of this is continuous investment in research and development in order to further improve the quality and areas of application of the steel mill slag. The aim is to make processes more sustainable and reduce the ecological footprint.

One of them is Slag Management. It includes liquid slag transport, mineral processing, metal separation and subsequent qualified slag marketing with associated R&D.
