Product sustainability

ArcelorMittal Luxembourg received the Environment award from the business federation FEDIL at the end of 2019 for its facility to recover the excess heat generated during the production of steel sheet piles on the ArcelorMittal Belval site.

The equivalent of 4000 heated houses per year

In June 2018, the Deputy Prime Minister, Minister of Ecology, Étienne Schneider, and ArcelorMittal Luxembourg Chairman of the Board of Directors and ArcelorMittal Board Member, Michel Wurth, gathered for the inauguration of the surplus heat recovery plant.

Since its inauguration, the heat emitted by the mill supplies the districts of Belval, Nonnewisen, and Summit. 200 customers are connected and can then cover 70% of the heating needs of the SUDCAL heating network.

"It is a great pride to see this project, fruit of an exemplary cooperation between an industrial player, the State and an energy operator, crowned with such an award. The reduction of our environmental impact is one of the major axes of our policy in favor of sustainable development and the circular economy implemented by the group in Luxembourg. With this project, we have shown that the pooling of complementary talents to control the environmental impact of the industry, it works! This initiative opens up great prospects for other actors in Luxembourg, who will be able to draw inspiration from it to multiply it," states Roland Bastian, Managing Director of ArcelorMittal Luxembourg.

CO2 reduction

The Belval site is composed of an electric steel mill and two rolling mills, including the 'train 2.' The facility contains a reheating furnace for raising the semi-finished products to 1300° C and since last year its fumes have been used to power the SUDCAL heating network. Exiting at 400°C, the fumes are sent to the recuperator to heat the water which is then directed to a water/water heat exchanger, at which time the water is finally ready to be sent to the homes heated by SUDCAL .

Thanks to the reuse of this energy, ArcelorMittal Luxembourg contributes to the reduction of the national energy consumption of the Grand Duchy and thus allows SUDCAL to reduce its environmental impact up to 5000 t of CO2 per year.

Version 3.04 of the AMECO software is now available for download.

The purpose of the AMECO software is to assess the life cycle of composite structures of buildings or bridges evaluating the environmental footprint, in particular the associated energy consumptions and greenhouse gas emissions.

This software is based on the principles of Life Cycle Assessment and is compliant with ISO 14040 & 44 and the new EN 15804 with evaluation of impacts: Global Warming Potential (GWP), Primary Energy Consumption (PEC), acidification & eutrophication potential, water consumption, etc.
 
Version 3.04 of AMECO proposes to take into account the use phase of the building (Module B). It allows the estimation of energy needs for a variety of the building systems, such as heating and cooling. The calculations are based on several international norms such as ISO-13370, ISO-13789, and ISO-13790 as well as the European norm EN 15316. The extension of the use phase is only available for buildings.

AMECO 3 is available in 16 European languages.

Built by First Solar, a leading provider of comprehensive photovoltaic energy solutions, the California Flats Solar Project in the Golden State of California in the United States is equipped with 874 trackers and 16 760 Exotrack® HZ V2 structures produced by ArcelorMittal Projects Exosun with about 30% of the components manufactured by Alliance Metal Changzhou, part of ArcelorMittal Projects.

Exotrack® HZ V2

Thanks to its balanced design and structural stiffness, our Exotrack® HZ V2 offers greater reliability and limited operating expense. It is a centralised tracker with only four motors per MWp, with high flexibility on uneven ground and unrivalled simplicity resulting in a smooth and fast installation.

ArcelorMittal Projects Exosun’s largest North American project

Commissioned in May 2019, this project is ArcelorMittal Projects Exosun’s largest project to date in North America. It is also the first one featuring First Solar’s Series 6 modules.

The solar plant will:

• generate enough solar energy to power about 116 000 homes per year
• generate clean and renewable energy and protect air quality in the region
• allow a reduction of 109 000 tonnes of CO2 annually - the equivalent of taking about 22 000 cars off the road
• allow a reduction of 152 000 tonnes of water consumption annually based on the average California grid
• support job creation

The California Flats Solar Project began construction in June 2016 and was completed in May 2019.

With a length of 560 km, the Moselle is a major European waterway, crossing France, Luxembourg, and Germany. Next April, a brand-new steel-concrete composite bridge will rise on the French bank of the river. It is currently being built with beams from ArcelorMittal Europe – Long Products assembled in box girders entirely prefabricated by Steligence® Fabrication Centre in Luxembourg. About 200 km from there, on the German bank of the Moselle, new locks are being installed thanks to ArcelorMittal Sheet Piling.

Safer and more efficient access on the river

Built in 1942, the old bridge located in Tonnoy, France was deteriorating and was no longer in line with the latest standards regarding mobility. With this new 92-metre bridge, user safety will increase thanks to a new footbridge dedicated exclusively to pedestrians and cyclists and a wider road for vehicles traffic. The bridge will also limit the impacts on the Moselle riverbed and ensure better hydraulic flow thanks to the presence of three pillars instead of four.

As for the locks in Germany, the existing ones are no longer up to date in their dimensions, causing waiting times at the lock passages. This is a major issue, especially when freight transport has to share the route with the abundant tourist excursion boats. As a solution, the locks will be equipped with a second lock chamber, in larger dimensions (210 m x 12.5 m). Thanks to the second lock chambers, waterways as ecological and economic modes of transport will become even more attractive, which will also strengthen the reputation of this economic area.

S460M: the key advantage to winning this bridge project

In early September, construction of the Tonnoy bridge took a huge step: the delivery on site and the installation of the box girders. The girders, fabricated and painted by Steligence® Fabrication Centre, are composed of 24 beams in grade S460M produced in ArcelorMittal Europe – Long Products’ mill in Differdange. They measure between 30.5 m and 35.4 m and weigh a total of 187 tonnes.

The use of S460M structural steel grade allowed for weight reduction, which was a competitive advantage in this project that was initially supposed to be completely built with concrete. Thanks to ArcelorMittal steel, construction time and costs were considerably reduced as there was no need for formwork, sanding, welding, or confinement.

For the installation of the 12 girders (eight 29.85-m girders of 2 beams and four 35-m girders of 2 beams), a 220-tonne lifting crane was used. Transportation was organised by the Steligence® Fabrication Centre with the help of MKTS transport company. This special transport had to be regulated by pilot cars and Luxembourgish and French law enforcement.

Improving waterway transport

Out of the ten locks that require work, the Zeltingen and Fankel locks are already extended and in operation. For the Trier lock, the overall construction comprises the extension of the upper and lower outer harbour to a length of 225 m, the relocation of the Trier water gauge, the construction of a new control centre for the locks of Zeltingen, Wintrich, Detzem, and Trier, as well as an ecological compensation measure at the Monaise sports boat harbour.

The upper outer harbour, the central piers in the upper and lower water, will be built using steel sheet piling from ArcelorMittal Europe – Long Products, produced in the Belva milll. A single anchored PU® 22 sheet pile wall will be used for the upper outer harbour and an approach dolphin in the lower water will be constructed as a circular cell from AS® 500 profiles – filled with sand or other material – that will be dismantled at the end of the new lock construction.

Works for the bridge are still ongoing on the banks of the Moselle with completion foreseen in April 2020. As for the Trier lock, completion should take place before the end of 2019.

ArcelorMittal Europe – Flat Products regularly joins forces with customers to create co-marketing opportunities. A recent event saw ArcelorMittal work together with Polish roofing specialist Regamet to promote organic coated steels to roofers. The goal was to increase sales. Results were very impressive with a 44 percent jump in sales of Regamet products made with Granite® steels.

Regamet and ArcelorMittal: partners for the long term

Regamet is a leading manufacturer of steel products for standing seam and traditional tiled roofs. The company buys many products in the Granite® range including HDX, Deep Mat, and Quartz. From August 2019, Regamet also started to use the latest member of the family – Granite® Ultramat.

“We purchase ArcelorMittal’s Granite® range to produce seven types of steel roof tiles,” notes Wacław Tryba, owner of Regamet. “We also offer trapezoidal sheets in seven different patterns and two types of roof panels. And then there are the accessories such as ridge tiles, water management parts such as gutters and downpipes, and fixing systems.”

ArcelorMittal provides graphics and assistance

When Regamet had the idea to undertake a major marketing campaign, they contacted ArcelorMittal for help. “ArcelorMittal shared graphics and helped us to fine-tune the messages for our network,” explains Mr Tryba.

That led to the development of posters and banners to promote the campaign at Regamet branches and other participating companies. Emails were sent to almost a thousand roofers.

ArcelorMittal helped Regamet to develop a range of co-branded helmets, caps, t-shirts, and thermal vests. Roofers could buy these promotional items, as well as a banner with their own contact details, for just 1 PLN (0,23 EUR) when they placed an order for more than 100 square metres of Granite® roofing products.

Photo competition adds new dimension to cooperation

The promotion also included a photo competition with prizes for images of the most interesting roofs made with Granite®.

At the end of the campaign, Regamet presented tools to the winners of the photography contest during the company’s annual training day for roofers in Kraków. “The results of the campaign were very satisfactory,” says Mr Tryba. “The roofers were eager to participate in the competition. 215 of them received clothes and gadgets or were awarded with tools. It has strengthened Regamet’s brand and increased awareness of ArcelorMittal’s roofing solutions amongst a key target group. The result? A 44 percent jump in orders for Granite® products.”

Would Regamet participate in a similar promotional event? “Absolutely,” says Mr Tryba. “Further activities are already scheduled for the fourth quarter of 2019 and beyond.”
