Catalysts not produced by us can be supplied by our collaborators Heraeus.

Ravindra Heraeus offers the entire spectrum of products and services related to precious metal catalysts. Spent catalysts are incinerated, analysed and precious metals recovered. The recovered metals are once again used to manufacture new catalysts.
