The first customer to which Thyssenkrupp Steel supplied flat steel from the bluemint® product family was premium bathroom manufacturer Kaldewei in Alain. This was reported by the press service of Thyssenkrupp.
According to the German steel company, the new steel is produced with a CO2 reduction in the blast furnace of more than 70%, which is confirmed by the international certifier DNV.
The effect is achieved through the use of HBI, hydrogen-reduced sponge iron. This allows less coal to be used for the blast furnace steelmaking process at the Duisburg plant. In addition, the company has tried to minimize all emissions that occur during the production and transportation of raw materials. Thus, the actual reduction in emissions per ton of finished steel is reduced by 1.5 tons to 0.6 tons, that is, by more than 70%.
“It is important for us to offer our customers CO2-reduced products as soon as possible, based on real and verifiable savings in carbon dioxide. This is the starting point today, ”said Bernhard Osburg, CEO of Thyssenkrupp Steel.
Using hot briquetted iron or recycled products as feedstock to reduce CO2 emissions are the first steps. Thyssenkrupp Steel also plans to expand the use of hydrogen in blast furnaces in the future.
