bluemint^® Steel – our high-quality flat steel with reduced CO₂ intensity

More than an interim CO₂ target: bluemint^® Steel.

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 most important properties at a glance.

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.

"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.
