Start saving up to 70 % of CO2 with bluemint®
RIGHT HERE. RIGHT NOW.
Under the names bluemint® pure and bluemint® recycled, two new climate-friendly products were added to our portfolio in the fall of 2021. The special thing about them is that the material properties do not differ from existing steel grades – except in their reduced specific CO2 emissions. The certified steels are produced at the Duisburg site.
This is the first transformation success within the framework of our climate strategy and reflects the high standard of sustainable and customer-oriented steel production. In the coming years, we will invest intensively in innovations and technologies that will bring our customers closer to the common goal of climate neutrality and a green steel product.
Two products, many advantages – bluemint® pure and bluemint® recycled. In a short film we explain what lies behind our green steel products with reduced CO2 intensity while maintaining the same quality.
The concept of low-carbon steels is of high interest to many processing and end-use industries. bluemint® pure is particularly attractive for customers who are aiming for CO2 savings in a global context. bluemint® recycled is aimed in particular at our customers for whom a high recycling content is important.
bluemint® pure and bluemint® recycled stand for the variety of our portfolio of grades. This means that you can rely on the continued availability of the familiar materials. In terms of material and processing properties, our two bluemint® Steel products fall by no means short of our existing grades. On the contrary: The high premium quality is complemented by a significant CO2 reduction.
This is substantiated by our certificates: bluemint® pure is certified by the DNV and bluemint® recycled by TÜV SÜD.
The concept of high-quality flat steel with reduced CO2 intensity is thus also currently gaining momentum in many processing industries. Consequently, it has also aroused marked interest among those in positions of responsibility at Snop. "The whole automotive industry is looking at emissions reduction right now. Snop has taken an active role and sees an opportunity here to secure the long-term supply of climate-friendly steel for OEMs to a certain extent," explains Hervé Daenens, VP Operations at Snop.
Specifically, thyssenkrupp Electrical Steel processes CO2-reduced hot strip from thyssenkrupp Steel into bluemint® powercore® in both Gelsenkirchen (Germany) and Isbergues (France). And it does so in the highest technological grades currently available – the top grades – and as the only company at all to do so in Europe. For the R&S Group, this regional factor should not be underestimated: "Global supply chains have come under significant pressure in recent years. Having a reliable supplier in Europe with thyssenkrupp Electrical Steel is a big advantage for us," says Mirco Gisin, head of the Transformers profit center at Rauscher & Stoecklin.
Managing Director Klaus Wilmes: "We are consistently committed to preserving the natural basis of life for future generations. Thanks to a patented design, we produce tinplate containers with significantly reduced material consumption and comparatively high performance." Daniela Schmiedle, Managing Director of Sika Deutschland AG adds about the joint project: "The cooperation is entirely in the context of sustainable packaging and is to be seen in connection with the realization of our company's net-zero targets."
"We know pladur® from the field of surface finishing. What really appealed to us was the corrosion resistance as well as its good formability and resilience against outdoor weathering. Ideal for the facade," explains Thomas Naydowski, Managing Director of the steel trading company Heinrich Schütt. "With bluemint® pladur®, we are making a contribution to sustainability and reducing the carbon footprint by around 70 percent – and at the same time achieving real savings in CO2 emissions from steelmaking at the Duisburg location. So, our decision could not have been clearer."
"Using rasselstein® tin plate made from bluemint® Steel can save up to 69 percent CO2," says Dr. Peter Biele, CEO of thyssenkrupp Rasselstein. "The real CO2 savings can help customers and their clients in turn to achieve their Scope 3 target. And all this without carbon offsetting, but only through alternative input materials in the steelmaking process. This primarily decreases the use of coal for the reduction process in the blast furnace."
"There has been a great and positive response from the market to this sustainability initiative from Zentis," says a delighted Thomas Stock, Managing Director of the twist-off cap manufacturer Pano Verschluss. "Produced from bluemint® tin plate, the PVC-free Blueseal® cap is a wonderful match for the Zentis product!"
The result: Over the full life cycle, which averages around 1.2 million kilometers, CO2 emissions can be reduced by over ten percent compared with a conventional wheel. "This means that a bluemint® wheel weighing 32 kilograms is better than significantly lighter forged aluminum wheels of the same size," reports Andreas Strecker. For trucks or commercial vehicles with lower mileages, such as refuse collection vehicles or concrete mixers, the advantage of bluemint® Steel is even greater, he says. Andreas Strecker: "This is a significant step toward greater sustainability in the commercial vehicle industry."
The use of bluemint® Steel is part of this. In a joint project, thyssenkrupp Rasselstein is supplying the CO2-reduced packaging steel, while Hoffmann Neopac is producing and printing the cans using solar power.
Among the buyers is the Swiss herbal candy manufacturer Ricola. "It was important for us to make the packaging of our herbal candies more sustainable. That's why we are the first company in our market to use CO2-reduced food cans," says Dr. Martin Messerli, Chief Operating Officer of Ricola. The company has already been producing with electricity generated from hydroelectric power since 2016. From the Ricola Group's point of view, the next logical step was to optimize the supply chain and the packaging of the herbal candies. "By switching to a CO2-reduced can for our herbal candy specialties, Ricola is also responding to increased demand from consumers, who are paying more attention to the carbon footprint of their purchases," says Messerli.
Holger Ketterer: "With the first goal, the energy transition is dealing us a good hand. The more renewable energies are used, the lower the CO2 emissions from energy losses. That's why our focus is already clearly on the climate impact of the materials we use."
E.ON also sees great potential in the more climate-friendly version of its well-known and proven products. "We are committed to a sustainable energy world for tomorrow – so it makes a big difference in the overall assessment of a plant if a substation or green power station also has transformers with CO2-reduced electric steel," says Achim Hübner, International Category Lead for transformers at E.ON.
Transformers play a central role in the energy transition, as they ensure the conversion and transmission of green electricity. To ensure that this happens with as little loss as possible, high-tech steels are used in the transformers, or more precisely: highly efficient grain oriented electric steel of the powercore® brand from thyssenkrupp Steel.
Christian Graap, Technical Managing Director at Kaldewei, sees the greatest lever on the path to climate neutrality in the conversion of the primary material to green steel. "Steel is the optimum material for us because of its robustness, its good formability and, not least, its recyclability. However, its coal-based production is reflected in the CO2 balance of our own products. This changes with bluemint® Steel. Its use is an important step toward achieving our own climate goals."
The Managing Director of Kaldewei, Franz Kaldewei, adds: "bluemint® Steel gives us the certainty that we are already using the highest quality steel with a lower CO2 intensity for the production of our enameled steel bathroom products. This is an important step towards achieving our climate targets. With the new bluemint® Steel from thyssenkrupp Steel, we are overcoming a major hurdle on the way to Kaldewei's climate-neutral alignment.
Numerous companies have signed a memorandum of understanding with thyssenkrupp Steel on the future supply of bluemint® Steel. There are now well over a dozen different MoUs (memorandums of understanding) in place in the Automotive, Industrial, Electrical Steel, Packaging Steel and Precision Steel sales areas. The cooperation partners currently include:
Amprion Enel | Benteler | Bilstein | CDW | EMW | Ford | Gedia | Italpack | Itla-Bonaiti | JFE Shoji | Kaldewei | Miele | MPE/ZF | Mubea | Risse + Wilke | Siemens Energy |Snop | Würth
