Optimised steel structures for a low carbon future15 February 2024
The construction industry is the world’s largest consumer of raw materials and the built environment accounts for between 25 and 40% of global CO2 emissions. The sector is responsible for nearly 40% of annual raw material use and around 39% of the total primary energy use. These numbers are set to increase.The most promising construction material in terms of low emissions and increasing circularity is steel. Although the steel industry is among the highest-emitting industries (about 7% of global carbon dioxide emissions), the carbon footprint of its manufacturing process has decreased over the last 25 years and today new low-carbon alternatives are cutting emissions faster than before. The circularity of steel, enhanced by the possibility to upcycle, unlike other materials, and its low-carbon alternatives have resulted in its use in innovative projects driven by sustainability.Efficient design of steel structures is key, designing with end-of-life in mind and specifying low-carbon alternatives. With design choices playing an important role, we need to rethink the design approach from a circular, more holistic, and therefore more sustainable perspective. The research paper ‘Why optimised steel structures will help reduce embodied carbon’ provides a brief overview of the steps being taken to decarbonise steelmaking and examines the impact of the construction sector on global emissions. The main objective of this paper is to put forth easy-to-use tools to help designers reduce the embodied carbon of their projects while offering guidance on evaluating sustainable solutions.Technical article
XCarb® recycled and renewably produced sheet piles contribute to the Sustainable Building Site certificate awarded to BVK headquarters6 February 2024
On the former Siemens site in Munich, Germany, the new company headquarters of the Bayerische Versorgungskammer (BVK) are being built. Züblin Spezialtiefbau was commissioned with the turnkey construction of the excavation pit, which impresses with its size and depth. A total of 188 300 m3 of soil will be excavated.A temporary sheet pile wall was installed for the excavation shoring. The contractor chose ArcelorMittal's PU steel sheet pile sections in the company’s XCarb® recycled and renewably produced range, which have a very low carbon footprint due to their scrap-based production exclusively using electricity from renewable sources (solar and wind).The overall project aims for a high level of sustainability and has already been awarded a ‘Sustainable Building Site’ certificate by the German Sustainable Building Council (DGNB).Project news
XCarb® recycled and renewably produced
XCarb® recycled and renewably produced (XCarb® RRP) steel is ArcelorMittal’s low carbon emission steel offer developed to reduce the CO2 footprint of steel production and thus the construction industry. It is produced in an electric arc furnace (EAF) using 100% renewable electricity and high levels of scrap steel. The electricity used in the steelmaking process is independently verified by a Guarantee of Origin proving it is from renewable sources, such as solar and wind power.*
All of our products available in XCarb® recycled and renewably produced steel are (or will soon be) certified by Environmental Product Declarations (EPDs).
*This is ensured by purchasing Renewable Energy Certificates, a market-based offering that certifies the bearer owns a specific amount (in megawatt-hours) of electricity generated from a renewable energy resource.
To produce XCarb® recycled and renewably produced steel, ArcelorMittal Europe – Long Products uses 100% scrap, and 100% of the electricity required for the steelmaking comes from renewable sources.
- Sections and merchant bars are available with a carbon footprint of 330 kg CO2e/t of finished product.
- The EcoSheetpile™ Plus range covers XCarb® RRP steel sheet piles with a carbon footprint of 370 kg CO2e/t of finished sheet piles.
- Reinforcing steel in bars and coils has a carbon footprint of 300 kg CO2e/t of finished product, which is far below the average carbon footprint of other rebars available on the market.
Panels & profiles
ArcelorMittal Construction, producer of innovative construction solutions for roofing, cladding, flooring, and light steel structures, is now offering sandwich panels and long span decking made from XCarb® recycled and renewably produced steel:
- Hacierco® long span decking profiles are now available with a carbon footprint reduction of up to 60%.
- Ondatherm® sandwich panels with a PIR (polyisocyanurate) core and a thickness of 80 mmm are estimated to have a 45% lower carbon footprint than the same panel produced with conventional steel.
EPDs for XCarb® RRP Ondatherm® sandwich panels and Hacierco® long span decking are expected to be published soon.
How does XCarb® RRP reduce the carbon footprint of buildings?
XCarb® solutions, which are now available for the majority of building applications, such as foundations, structures, flooring, facades, and roofing – and potentially joinery, fittings, and equipment - can lead to an overall carbon footprint reduction of 40% at building level (taking into account modules A to C).
- Thanks to the use of XCarb® RRP steels for structure and facades, the carbon footprint of an industrial or commercial building of 1300 m2 can be reduced by around 40%.
- For a 24 m double-span logistics warehouse, the carbon footprint reduction is also approximately 40% when using XCarb® RRP steels in its structure, facade, and roof components.
Looking at finished steel products made from XCarb® RRP steel for different building components, carbon reduction can be as follows:
- Rolled steel section: -60% CO2
- Composite flooring sheet: -60% CO2
- Facade and roofing sandwich panel: -36% CO2
- Cold formed profile: -64% CO2
- Roofing profile: -57% CO2
- Garage door: -36% CO2
At the end of a building's life or during renovation operations, XCarb® steel solutions can also be 100% recovered and are recyclable.
