This figure would be even higher by more than 14 % if no secondary materials were already used in industrial production. For example, production of secondary Cu is advantageous due to lower energy consumption and conservation of scarce natural resources. The presentation will discuss pathways to increase the use of secondary raw materials to foster a circular economy with a focus on waste treatment processes.
