Lucerne Emmenbrücke based green steel leader Swiss Steel Group is on average 78% better than producers pursuing the blast furnace route when it comes to CO2 emissions as it is one of the Europe’s largest steel producer using the EAF route. Swiss Steel Group 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.Swiss Steel Group 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 Swiss Steel Group 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% 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.Swiss Steel Group 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 Swiss Steel Group 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.Swiss Steel Group 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.
