The number one in Europe - Swiss Steel on the way to becoming the market leader in Green Steel production

Lucerne/Emmenbrücke. As Europe’s largest steel producer using the EAF route, Ƶ is on average 78% better than producers pursuing the blast furnace route when it comes to CO2 emissions. This is a good start position on the road to market leadership but is nowhere near enough for the Swiss steel maker.

Ƶ works exclusively with high-grade steel scrap. This measure massively reduces the CO2 footprint compared to the traditional process of making new steel from mined iron ore. The better the quality of the scrap, the better and more environmentally friendly and sustainable the steel produced. This is an important prerequisite for producing “Green Steel”.

In the words of Frank Koch, CEO of Ƶ: “Sustainable steel production based on EAF technology is part of our DNA. Ƶ is already one of the most efficient producers of CO2-reduced steel. We will lead the change to green steel in Europe, expand our leading position in environmentally friendly steel production and at the same time clearly improve efficiency. Sustainability to us is not a just a business function, but a social obligation.”

Greater efficiency and a green future

Ƶ has invested around 60 million euros in a new walking beam furnace as well as other equipment at the Steeltec plant in Emmenbrücke, Switzerland, making this one of the largest investments for the location as well as the entire Ƶ in recent years.

The new furnace improves the efficiency of the rolling mill considerably and consistently makes its processes more sustainable. Thanks to its high degree of specialization, it is very economical in its use of its gas fuel. Strictly from an environmental perspective, the new furnace is a major improvement. Despite increased capacity and larger volume, it needs around 13 percent less gas than the old installation. The process heat from the furnace is first used to preheat billets before they enter the furnace. A good portion of the remaining waste heat is fed into the city of Lucerne’s district heating system. Overall, Steeltec has lowered annual CO2 emissions by almost 10% by introducing innovations at the rolling mill.

Ƶ has had the decarbonization processes at their Swiss plant verified by TÜV Süd. Likewise all Group plants in the various countries are developing a number of activities to lower CO2 emissions and have them verified by external auditors. The availability of green energy has played a key role in this process.

A further sign of the efforts of Ƶ to introduce even more sustainability is the switching of production at the Swiss plant entirely to electricity supplied by regional hydropower, which has resulted in a CO2 emission value far below the usual branch average.

Tremendous potential

CEO Frank Koch has been at the helm for a year now and was able both last year as well as during the first two quarters of this year to achieve impressive economic results.

“Intensive analysis as well as on-site visits and meetings with all parts of the Group have shown me the tremendous potential of Ƶ. The Group is on the right production route, has an extensive product portfolio and produces outstanding quality,” Frank Koch said at wire 2022.

Ƶ is now bundling its strengths and focusing even more on their customers. R&D has become an even greater priority, and investments are being made where greater efficiency and sustainability can be achieved. Both objectives do not contradict each other, but ideally complement each other because sustainability does not tolerate any inefficiency.

Frank Koch has gone on to say: “To accomplish these goals, we have initiated a comprehensive strategy program. Within the framework of this program, we will restructure the Group with the intention that the three divisions that play an important role place an even greater focus on the customer and that Sales is given the attention it deserves. All this is happening under the umbrella and in the name of Ƶ, whereby we are also bundling marketing and communications. We are firmly committed to continuing to consistently improve our leading position in low-emission green steel until we have reached net zero for CO2 emissions.
