Highly efficient technologies for increased yields in steelmaking processes and reduced environmental impact

The HIYIELD project addresses the need for sustainable and competitive steel production, essential to achieving a climate-neutral, circular, and digitized industrial framework. As the steel industry is responsible for approximately 7% of global CO₂ emissions, reducing reliance on carbon-intensive pig iron from coal-fired blast furnaces is critical. HIYIELD addresses this by promoting circular economy principles and increasing scrap uptake across key European steelmaking routes, including Electric Arc Furnace (EAF), Basic Oxygen Furnace (BOF), and Argon Oxygen Decarburization (AOD). The project focuses on improving scrap quality through advanced impurity removal techniques and optimal retention of alloying elements. Furthermore, it introduces digital and data-driven solutions to optimize process efficiency and product quality. These include deep learning-based computer vision for scrap identification, digital scrap information cards for traceability, and high-speed liquid steel analysis for real-time process control. By integrating these technologies, HIYIELD aims to support the steel sector’s transition towards lower emissions while maintaining high performance standards and industrial competitiveness.

The HIYIELD project is led by KUNGLIGA TEKNISKA HOEGSKOLAN/Sweden (KTH) and includes a consortium of steel producers SAARSTAHL/Germany (SAG), STAHL HOLDING SAAR/Germany (SHS), Voestalpine BÖHLER/Austria (BÖH), FERRIERE NORD Pittini/Italy (FENO), scarp providers STEIL/Germany (STE), AEIFOROS/Greece (AEIF), and technology partner MINKON/Germany (MIN).
