Stahlwerk Thüringen (SWT) represents one of the most advanced real-world implementations of RHI Magnesita’s 4PRO business model, demonstrating how the pillars Performance, Partnership, People, and Planet converge to drive continuous improvement and deliver measurable metallurgical, environmental, and economic value.
This success is rooted in a 30-year partnership, during...
The decarbonisation of Electric Arc Furnace (EAF) steelmaking requires the progressive substitution of fossil-based carbon with renewable, biogenic alternatives able to guarantee adequate melting performance, slag foaming behaviour, and process stability. The RFCS project BioReSteel addresses this challenge by developing and validating new biogenic Secondary Carbon Carriers (SCCs), with a...
Efficient management of the scrapyard is essential to improve steelmaking productivity, yet visual mapping and material classification often remain manual and error-prone. This paper presents new solutions developed by Polytec that combine advanced vision systems, AI-driven analytics, and robotic automation to map, classify, and sort scrap materials in real time. The systems integrate...
Electric Arc Furnace (EAF) steelmaking generates CO₂ emissions from both direct process-related sources and indirect electricity consumption. While indirect emissions associated with grid electricity dominate overall emissions, direct process emissions—primarily from carbon additions used for slag foaming and refining—remain a significant and addressable source.
This paper will quantify...
The steel industry, which accounts for 7% of global anthropogenic CO2 emissions, is undergoing a major transition to reduce its carbon footprint, with several technologies being developed, trialled and commercialised at different scales, including scrap-based electric arc furnace (EAF), hydrogen direct reduced iron (HDRI)-EAF, hydrogen direct reduced iron (HDRI)-electric smelting furnace...
The global steel industry is under pressure to reduce carbon emissions. Electric Arc Furnaces (EAF) plays a major role in current steel production with low carbon footprints. Currently, around 30% of global steel production is carried out using EAF. With the growing demand of lower carbon footprint Direct Reduced Iron (DRI) process and increased amount of scrap, demand for EAF steel making is...
