01
Most common
Ceramic converters (cars)
A ceramic (cordierite) honeycomb in a stainless steel shell – from petrol and diesel vehicles, as main, pre- or manifold converter.
02
Metallic substrate
Metallic converters
A substrate of thin wound metal foil instead of ceramic. Often used as pre-converter, in sports vehicles and motorcycles. More complex to process.
03
Diesel
Diesel particulate filters (DPF / FAP)
Filters made of silicon carbide or cordierite. Some are coated and contain platinum, others hardly any precious metal.
04
Modern diesel
Combined systems (cat + DPF)
Oxidation catalyst and particulate filter in one shell, as in many current diesel vehicles.
05
Loose material
Monoliths & broken ceramic
Removed ceramic, whole or broken. Please hand it over in tightly closed bags or containers – never transport ceramic dust uncovered.
06
Large
Truck, bus & industrial converters
Large units from commercial vehicles, buses, construction machinery, forklifts and stationary engines.
07
Small
Motorcycle & small converters
Small units from motorcycles, scooters and small engines, often with a metallic substrate.
08
To be honest
Aftermarket converters
Replacement parts from the accessories trade. We accept them – but their precious metal loading is usually low, and the price is lower accordingly.
