Spent Precious Metal Powder Catalysts are sent to a metals refinery where the precious metal is extracted from the catalyst. The catalyst is destroyed in this procedure. The refinery produces fresh precious metal salt solutions that are subsequently used in the production of fresh precious metal powder catalysts. This is the way how the precious metals are kept in a loop and the loss of precious metals is minimised.

Evonik takes care of the whole precious metal cycle. It starts with the management of the precious metal account and ends with the coordination of all activities around recovering the precious metals. Evonik has a well established global network of refiners who do the refining for Evonik. However, we keep it simple. There is only one interface between Evonik and the customer.
