Spent Automotive Catalysts

Catalytic converters play a key role in reducing harmful emissions to our environment and contain valuable Platinum Group Materials. We have the expertise and knowhow to carefully determine and extract the Platinum, Palladium and Rhodium content in end of life catalytic converters. Once recycled, these metals can be used to produce new catalytic converters for next generation vehicles, thus closing the materials loop.

Umicore refines both metallic and ceramic based catalysts, including silica carbide based diesel particulate filters. Below you may find an overview of the different types and ideal lot sizes.
