Researchers in the CRC develop process and process chain innovations for oxygen-free production. In this subproject, economic effects of these innovations are investigated. Therefore, technical effects of these innovations are first identified in cooperation with relevant subprojects of the CRC. Subsequently, the correlations between technical and economic effects will be deduced and experimentally investigated by means of simulation studies. Moreover, these correlations will be described as well as represented to support the CRC's research and future innovation decisions in practice.
