  1. 146. Hurricane – Sector coupling hub for circular use of thermal and industrial waste
    Mr Philippe Alboort

    Environmental and energy aspects in iron and steelmaking
    Oral Presentation

    Within HURRICANE a sector-coupling circular hub centred around the ArcelorMittal Ghent site will be created. We will target efficient resource management together with the recovery and utilization of squandered industrial waste heat and water. Together with ArcelorMittal Ghent’s ongoing initiatives, this will lead to a reduction of energy, water and raw materials. Thanks to the ongoing...

  2. 377. Recent achievements of Industrial Symbiosis in the steel sector based on the Symbio-Steel project

    Environmental and energy aspects in iron and steelmaking
    Oral

    Industrial Symbiosis concerns the use by one company or sector of underutilized resources from another one, resulting in reducing dependence on critical materials, mitigating supply risks, replacing virgin materials, and, consequently, reducing CO2 emissions, and transforming existing resources in the value chain into a usable form. Implementing the Industrial Symbiosis concept provides new...

  3. 428. Upgrading of low-quality iron ores and mill scale with low carbon technologies

    Environmental and energy aspects in iron and steelmaking
    Oral

    Iron ore and scrap as raw materials are the base of iron and steel production. Due to the transition from carbon to hydrogen-based green iron and steel production, most current production units as sinter plan, blast furnace and basic oxygen furnace will be replaced by the direct reduction process followed by the electric arc furnace. As a result, recycling routes via BF-BOF-technologies will...

  4. 406. Assesment of the natural absorption of CO2 performed by steelmaking slag
    Prof. Carlo Mapelli (Dipartimento di Meccanica - Politecnico di Milano)

    Environmental and energy aspects in iron and steelmaking
    Oral

    Electric Arc Furnace (EAF) and Ladle Furnace (LF) slag, a byproduct of steelmaking, has emerged as a promising material for the natural capture of CO₂ through a process called mineral carbonation. Composed primarily of calcium and magnesium oxides, EAF slag reacts with atmospheric CO₂ to form stable carbonates, such as calcite and magnesite, under ambient conditions. This natural carbonation...
