Ferrous slag, a by-product in the production of pig iron and steel, is a high-quality, economical and versatile raw material. Processed into ground granulated blast furnace slag, aggregate, or lime-rich fertiliser, it has been used in the construction industry and in agriculture for decades.
The FEhS Building Materials Institute in Duisburg, located in the centre of Europe and at the heart of the steel industry, is the first address in Europe for research, testing and consulting in relation to ferrous slag, construction materials and fertilisers. As a state-of-the-art service provider, our experts, network and Construction Competence Forum make us a desirable partner for our members, and for customers from around the world.
In the future, there will increasingly be a focus on the resource-efficiency and sustainability of products: one of the great challenges of our time, and one with which the FEhS Institute has been intensively occupied since 1950. We are thus making an important contribution to economic and ecological development, and are also thus securing our leading role for the future.

If one were to make a heap of all the slag used since 1945 – over a billion tonnes – the tower would be 600 metres wide and 2,900 metres high, making it the same size as the highest mountain in Germany, the Zugspitze.
