Diesel Particulate Filters: More than soot

Particulate filters reduce the amount particles in the emission of Diesel engines. They are based on a ceramic honeycomb structure, most often coated with an amalgamation of precious metals. After some time the filter is clogged with ashes and soot and has to be replaced.

We asses the precious metal content of the filters and subject them to a procedure similar to that of the ceramic catalysts, ensuring efficient recycling with minimal losses.
