International conference on ferrous slags

Registration for the 12th EUROSLAG in Bilbao open – Abstracts until 30.4.24


Duisburg, 6 March 2024. Decarbonization and transformation, resource conservation and circular economy: The enormous economic and ecological challenges can only be overcome at an international level. This also applies to ferrous slag and the products made from it. Under the title “Slag for the Future, the Future of Slags”, the European network EUROSLAG is organizing its 12th conference from 23 to 25 October in Bilbao. Registration is now open at or Participants and speakers from all over the world are expected to attend. Interested parties can also submit their abstracts for papers and posters via the website until April 30, 2024. SIDEREX, the Basque Steel Cluster Association, and UNESID, the Spanish Steel Industry Business Association, are organizing the event with the support of PLATEA, the Spanish Steel Technology Platform, and EUROSLAG.

Central topics of the event are the influence of the decarbonization process on the properties and availability of slags, the impact of legislation and standardization including technical and ecological issues, innovative production and processing, characterization and use of slags, new areas of application and the recovery of metallic raw materials from ferrous slags.

Thomas Reiche, Managing Director of FEhS – Institute for Building Materials Research and Chairman of EUROSLAG: “Science and industry, research and companies are working hand in hand worldwide to make enormous efforts to be able to use ferrous slag in cement and concrete, as a transport construction material, in fertilizers or new fields of application in the future. This not only benefits numerous industries. It also benefits the earth’s increasingly scarce natural resources and the climate. We want to set an example in Bilbao that a lot can be achieved together and look forward to groundbreaking presentations and an interesting exchange.”



EUROSLAG brings together 26 organizations and companies from 17 countries, including the FEhS Institute. As a European network for the production, use and development of ferrous slags and slag-based products, EUROSLAG’s activities focus on research and technology, European standardization, and internal and external communication. Every two years EUROSLAG organizes the Slag Conference together with national partners.

All about ferrous slag

Updated brochure with new chapter on transformation 


Duisburg, September 13th, 2023. The FEhS Building Materials Institute has updated its brochure “Ferrous slag. Valuable raw material for resource-saving management”. With latest figures of 2022, it provides information on the production and use of the by-product of steel production, as well as on CO2 emissions saved and quantities of natural rock substituted. New is the chapter “Transformation of the steel industry and new slags”, which is dedicated to the decarbonization of steel production. The 20-page compact publication with numerous graphics is available in print and as a pdf at in the download area. 

In eight chapters, the brochure “Ferrous Slag” provides a comprehensive overview of the secondary raw material: from its production and technological and ecological properties to its various applications as a building material, in traffic route construction and as a fertilizer, to an outlook on the future by-products of hydrogen-based steel production. Extensive, graphically prepared figures, for example on resource and climate protection using ferrous slag, make the publication a useful information tool for architects, engineers, building contractors, representatives of public authorities and politicians. 

Thomas Reiche, Managing Director of the FEhS Institute: “With the Compact Brochure 2023, we want to show the contribution of the steel industries’ by-products to a sustainable circular economy. Because only those who are comprehensively informed can act in an economically and ecologically sensible way. This applies above all to the future use of secondary raw materials, which conserve natural resources and the climate even in First Life.“
