Chemicals
We recover metal concentrates containing nickel, copper, zinc or precious metals from etching solutions, spent electrolytes and rinsing water from the surface finishing industry. These are then further processed in additional metallurgical processes to produce basic chemicals up to pure metals. In this way we return the metals contained in these wastes to the economic cycle in a variety of ways.
In addition, we are developing new recycling processes to allow us to close the material cycle for increasingly complex metal-bearing wastes.
