Cooperation between Aurubis and Grillo-Werke yields a perfect closed loop for copper and zinc
Aurubis, an expert in multi-metal recycling, and Grillo-Werke, specialised in zinc and sulphur products, cooperate to make a perfect closed loop for non ferrous trace elements.
Residual zinc from copper production is used by Grillo-Werke as a secondary raw material for zinc sulfate. Residues from this production - including copper, tin and lead - are then fed back to Aurubis.
