The steel industry is an important engine for sustainable growth, added value, and high-quality employment within the European Union. It is committed to reducing its CO2 emissions due to production by up to 50% by 2030 compared to 1990′s level by developing and upscaling the technologies required to contribute to European initiatives, such as the Circular Economy Action Plan (CEAP) and the European Green Deal (EGD). The Clean Steel Partnership (CSP, a public–private partnership), which is led by the European Steel Association (EUROFER) and the European Steel Technology Platform (ESTEP), defined technological CO2 mitigation pathways comprising carbon direct avoidance (CDA), smart carbon usage SCU), and a circular economy (CE). CE approaches ensure competitiveness through increased resource efficiency and sustainability and consist of different issues, such as the valorization of steelmaking residues (dusts, slags, sludge) for internal recycling in the steelmaking process, enhanced steel recycling (scrap use), the use of secondary carbon carriers from non-steel sectors as a reducing agent and energy source in the steelmaking process chain, and CE business models (supply chain analyses). The current paper gives an overview of different technological CE approaches as obtained in a dedicated workshop called “Resi4Future—Residue valorization in iron and steel industry: sustainable solutions for a cleaner and more competitive future Europe” that was organized by ESTEP to focus on future challenges toward the final goal of industrial deployment.

The current issue of Steel Research International puts its focus on research activities of K1‐MET, the Austrian competence center for excellent technologies in advanced metallurgical and environmental process development. K1‐MET is part of COMET (Competence Center for Excellent Technologies), the Austrian program for competence centers from the Austrian Research Promotion Agency (FFG). COMET is funded by the Federal Ministry for Climate Action, Environment, Energy, Mobility, Innovation and Technology, the Federal Ministry for Digital and Economic Affairs, the provinces of Upper Austria, Tyrol and Styria as well as the Styrian Business Promotion Agency (SFG) and the Standortagentur Tyrol. Furthermore, the Upper Austrian Research continuously supports COMET. Leading industrial companies as well as excellent scientific institutions are the key partners of K1‐MET. CO2 lean production of metals and a cross‐sectorial approach to substantially improved production processes to transfer solutions from science to industry are three main goals of K1‐MET. The target for the current funding period 2019‐2023 is to enhance the position of K1‐MET as a leading and internationally renowned metallurgical competence center.

A circular economy is one of the important pillars of a sustainable iron and steel industry. Solid and sludgy residuals from steelmaking processes represent secondary resources with considerable amounts of valuable materials such as metals and minerals. Therefore, several treatment technologies for dusts and sludges target material recovery. The main benefits are a lower demand for primary resources and a reduced landfill volume as well as economic savings for steel plant operators. The current review article gives an overview of the amounts of steelmaking residuals generated in Europe and describes the OxyCup® shaft furnace, the integrated DK recycling route, and the Befesa Waelz rolling tube furnace process in detail, which represent currently operating state-of-the-art treatment technologies in detail. Nowadays, European steel producers reach a byproduct recycling rate of up to 95% (including onsite recycling and residual utilization performed by external companies). A benefit analysis was performed by several experts from Germany comparing different residual-treatment processes in terms of feed flexibility, product recovery, and material cycle closure. The study revealed that the OxyCup® shaft furnace and the DK route are more favorable compared to the Befesa Waelz process. However, moderate effort is required to implement the Befesa Waelz process in an existing steelmaking process chain, which is one of the advantages of this technology.
