Ms Nicole Voigt07/10/2025, 16:40Environmental and energy aspects in iron and steelmakingKeynote Presentation
The steel trade has long been a cornerstone of interconnected global production networks. Yet, as the industry faces unprecedented challenges—ranging from chronic overcapacity to divergent decarbonization trajectories—the protection of domestic markets is emerging as a critical priority. Around the globe, measures such as anti-dumping regulations, tariffs, safeguards, and subsidies are...

Wind power plays a central role in the global energy transition and is one of the most sustainable methods of electricity generation. It harnesses the kinetic energy of the wind and converts it into electrical power through wind turbines, without emitting greenhouse gases. Windmills are a crucial component of the shift to renewable energies as they provide a reliable, cost-effective, and...

In order to remove fossil carbon from the metal industries, biogenic carbon sources are needed. Progress has been made in using biogenic carbon substitutes in pilot and industrial-scale trials. However, challenges remain in the production and use of metallurgical biocarbon products, particularly in areas such as policy support at national and EU levels, commercial financial incentives,...

Thomas Steinparzer (Primetals Technologies Austria)07/10/2025, 17:40Environmental and energy aspects in iron and steelmakingOral Presentation
The transition towards green steelmaking necessitates fundamental modifications to existing production routes, particularly through the integration of electric arc furnaces (EAF) within integrated steel plants. This shift offers operators new opportunities, including the production of new steel grades and flexible raw material inputs. However, the environmental implications of EAF...

Mr MATTEO GILI (RINA-CSM)07/10/2025, 18:00Environmental and energy aspects in iron and steelmakingOral Presentation
The iron and steel sector leads in CO2 emissions and ranks second in energy consumption among heavy industries. It directly contributes 2.6 gigatonnes of carbon dioxide (Gt CO2) annually, accounting for 7% of the global energy system's total emissions. Currently, it is the largest industrial coal consumer, meeting approximately 75% of its energy demand. Despite global reliance on blast...

Mr Andrea Salimbeni (Re-Cord)07/10/2025, 18:40Environmental and energy aspects in iron and steelmakingOral
The utilization of biochar as valid alternative to fossil coal for steel bath carburization and slag foaming has already been proved with small scale and industrial tests.
Go to contribution page
The material availability and the related cost remain important issues to allow the utilization of biochar in current industrial practice. Reusing biogenic wastes is a promising solution, but the concentration of inorganics...
