Aurubis, an expert in multi-metal recycling, and Grillo-Werke, which specialises in zinc and sulphur products, have set up 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.

The ECONYL® Regeneration System turns fishing nets, fabric scraps, carpet flooring and industrial plastic into an infinitely recyclable nylon raw material.
