The most important factor is the optimum result with the lowest possible use of energy and spray media - and therefore a significant reduction in the overall CO 2 balance of a steel mill. Due to our in-depth understanding of the process, we are able to support steel mill operators directly in optimizing their steel quality.

replace carbon in steelmaking. Thus, the resulting steel-mill waste gases are unavoidable residues of industrial production. The residual gases produced through this reaction represent the biodegradable fraction of industrial waste and are an inevitable consequence of the chemistry of steel making. They contribute to 5-7% of global CO 2 emissions.
