Abstract Many approaches focus on more efficient production processes, on avoiding waste and scrap and on more efficient use/operation of products within one life cycle, i.e. from raw materials to the end of use. All these approaches share the goal of an increase in resource efficiency. In contrast, the reProd® approach is characterized by a comprehensive view of cycles. By shortening the cycle process, a huge potential can be opened up for metal products regarding a reduction of energy requirements and CO 2 emissions. Approx. 70% to 90% of the energy requirements and also of the greenhouse gas emissions are necessary for melting the metals and for the first processing stage. If secondary semi-finished products are obtained from used goods, energy-intensive processes are eliminated. Thus a decisive contribution for the energy turnaround and for protecting climate and environment lies in “non-destructive recycling” and “re-use without melting”
