Stefan Mühlböck (Primetals Technologies GmbH)09/10/2025, 11:00CO2 mitigation in iron and steelmakingOral Presentation
The transition to carbon-free steel production presents significant challenges for the industry. Adapting to new processes, production routes, and logistics is a central aspect of this transformation. Particularly notable is the shift from traditional Blast Furnace (BF) / Basic Oxygen Furnace (BOF) route to electric steelmaking route. This change requires not only a comprehensive restructuring...

Mr Andrea Pezza (Badische Stahl-Engineering)09/10/2025, 11:40CO2 mitigation in iron and steelmakingOral Presentation
The path to reducing steel's CO₂ footprint is increasingly clear, with the industry shifting toward electric arc furnace (EAF) steelmaking. This transition relies on recycled scrap and partially substitutes virgin materials with direct reduced iron (DRI) or hot briquetted iron (HBI). However, the changing quality of input materials, particularly the reduced purity of raw materials and...

Prof. Silvia Barella (politecnico di milano)09/10/2025, 12:00CO2 mitigation in iron and steelmakingOral Presentation
The steel industry, responsible for 7% of global CO₂ emissions, significantly contributes to environmental pollution and intensive water consumption. Decarbonizing the sector requires adopting innovative technologies such as hydrogen-based direct reduction, recycling in electric arc furnaces (EAF), and iron ore electrolysis. However, this transition presents major challenges, including the...

Georges Stamatakis (SMS group)09/10/2025, 13:20CO2 mitigation in iron and steelmakingOral Presentation
The iron and steel industry contributes significantly to global greenhouse gas emissions, accounting for 7.2% of the total. The predominant BF-BOF ironmaking route, responsible for 70% of global pig iron production, is primarily coal-based, posing substantial challenges for decarbonization. As steel industry stakeholders strive to reduce carbon footprints while maintaining economic viability,...

In this contribution we aim to illustrate how LCA can be used to support the decision-making process within the context of GreenHeatEAF “Gradual... -
Dr Oday Daghagheleh (Primetals Technologies Linz GmbH)09/10/2025, 14:00CO2 mitigation in iron and steelmakingOral Presentation
As part of the decarbonization process in the steelmaking industry, the direct reduction of iron ores, the use of green hydrogen as an energy source and/or the application of carbon capture technologies are crucial for achieving carbon neutrality. The study will underscore the importance of laboratory material testing and process simulation tools in determining the optimal and most feasible...
