Netherlands: Tata Steel IJmuiden (TSIJ) and Ecocem Materials Ltd (Ecocem) have signed a Memorandum of Understanding (MoU) to strengthen their collaboration on the development and potential use of two steelmaking slags in low‑carbon cement, mortar and concrete applications across Europe.
The MoU builds on an existing joint research program and sets out a shared intention to explore new technical, commercial and regulatory pathways for the valorisation of steelmaking slags produced at TSIJ. Alongside the existing commercial relationship between TSIJ and Ecocem for the valorisation of Granulated Blast Furnace Slag (GBS) in cement and concrete, this new collaboration focuses on basic oxygen furnace (BOF) slag as an alternative cementitious material, alongside the continued development of electric arc furnace (EAF) slag as a supplementary cementitious material.
The aim of the BOF and EAF slags project is to transform these steel industry by-products into cementitious binders or constituents that can support the decarbonisation of cement and concrete production, while advancing circular economy principles. By developing new pathways for the beneficial use of these materials, the collaboration also aims to increase the availability of low-carbon concrete solutions in the market, providing designers, concrete producers and contractors with a broader range of sustainable material options.
