In the pursuit of a sustainable refractory and steel industry, the circular economy offers the most resilient answer. RHI Magnesita and MIRECO close the loop by engaging producer, user and recycler of refractories. In addition to the CERO Waste Concept, this approach also involves a slag engineering solution and circular metallurgical additives. The CERO (Continuous Economic Recycling...

Prof. Marc Hölling (Hamburg University of Applied Sciences)22/05/2025, 08:50By-product management in iron and steel productionOral Presentation - Full Paper will be submitted
The metal industries face huge challenges in terms of sustainability, diminishing resources and the need for higher recycling rates. As an example, the alumina production creates red mud as the by-product of the Bayer-Process for the conversion of bauxite to alumina. Due to its environmental impact, it is stored in residue storage areas like dammed ponds or landfills. On the other hand, it is...

In the steel mill, additionally to the room dedusting after the converter there is also coarse and fine dust generated. These dusts have different chemical compositions. There are significant differences, particularly in the zinc-, quicklime- and metallic iron-content. Therefore, some of the dust is passed on to external recyclers and some is recycled internally. Internal recycling means that...
