C stands for the current class

The electric steel mill currently offers the best solution. Here, the scrap is melted into steel in an electric arc furnace (EAF) using an energy mix. The so-called "recycling route" can be further improved by using green electricity. Current obstacles are the availability of green power and the economic viability due to electricity costs.

Mixed current is used to melt scrap into steel in the electric arc furnace. Due to the recycling-related by-elements, only a limited range of grades can be produced. By using green electricity, the process route could be rated one grade better. In general, this process route should only be seen as a bridge technology or supplementary technology, as the available scrap quantities are not sufficient to cover the entire steel demand.

The Label:

The classification label makes the various solutions offered by steel producers transparent. The focus is on the sub-process with the highest emissions, namely crude steel production. To this end, Stahlo has developed a combined label which, on the one hand, represents the various elements of production using simple symbols and, on the other, divides the resulting CO2 emissions into 7 classes. A distinction is made between class G, for the classic blast furnace process with 1,800-2,200 kg CO2e per ton of crude steel, to the best class A with less than 150 kg CO2e per ton of crude steel. The data basis for the classification is the information provided by the manufacturer or the technical literature. The Stahlo classification label shows the main differences in a simple but ingenious way. If the steel mill quantifies the CO2 impact even beyond the crude steel condition, we add an additional "+" (plus) to the class and underline that the consideration is extended to the hot rolled coil.
