Foundations of a better world

In June 2023, ArcelorMittal broke ground on our new global headquarters in the Kirchberg district of Luxembourg. Within three years, this iconic building will showcase steel as the best and most sustainable material for construction.

Imagined by French Architect Jean-Michel Wilmotte, supported by ArcelorMittal Global R&D teams, this new building is designed with decarbonated steel and aims for certification by three major sustainability labels: BREEAM, DGNG, and WELL.

Its concept proposes a holistic approach to construction putting in practice fire engineering theories, composite beams and floors coupled to long span girders without intermediate column giving the construction an outstanding flexibility.

The construction of the new headquarters officially started on 21 June 2023, following a groundbreaking ceremony.

The materials we are using include beams, heavy plate, Magnelis®, and a range of other flat and long products from ArcelorMittal. Most of these materials are supplied with XCarb® green steel certificates and/or XCarb® recycled and renewably produced, enabling us to reduce our Scope 3 emissions.

ArcelorMittal recently launched heavy plate produced using the XCarb® recycled and renewably produced (RRP) route. Made with almost 100% scrap steel and 100-percent renewable electricity, the carbon emissions of this product are over 60-percent lower than steel made via the conventional blast furnace route.

Heavy plates are produced at ArcelorMittal Europe’s mill in Gijon (Spain).

Despite their different production routes, the heavy plate produced via the blast furnace (with XCarb® green steel certificates) and the XCarb® recycled and renewably produced heavy plate have similar properties. That means we can easily incorporate new recycled and renewably produced products into the construction and improve the environmental profile of the building as ArcelorMittal’s decarbonisation efforts gather pace.

Using sustainable steel construction principles and ArcelorMittal products has enabled us to reduce the height of the building. The final structure will be seven to ten times lighter than one made from traditional materials, and have a significantly lower carbon footprint.

Steel products are combined easily, as in this building’s infrastructure. Solutions deployed include slim floor beams, hot-rolled steel beams joined with heavy plate, and light gauge steel floor decks. The design reduces the use of concrete and makes the floor thinner. As well as cutting the structure’s weight, this approach contributes to reducing the height of the building and its carbon footprint.

But we’re going further and looking to a future circular economy when this building reaches the end of its useful life. In 2024 ArcelorMittal will launch a competition involving major European architectural faculties. The students will be asked to imagine how they would reuse components from ArcelorMittal’s headquarters in 50 years. With more than 10,000 tonnes of steel used to create the building’s structure – there will be a lot of material for them to work with!

As most of the steel is protected – with coatings such as Magnelis® or by being inside the building – it will have the same strength and properties as it does today. The steel is also easy to re-cut and re-dimension. And any waste can be recycled to create new steel.

In theory this process of reuse can continue forever. It will also ensure that ArcelorMittal’s new global headquarters continues to contribute to creating a better world – today and in the future.
