Catalyst types
Ceramic monoliths (DPF / FAP)
Large substrates from diesel engines — combine catalyst and particulate filter functions. The highest rates in our pricing.
A monolith is a larger, heavier substrate found mainly in diesel vehicles (DPF — Diesel Particulate Filter, FAP — Filtre à Particules). It combines soot filtering with emission catalysis. Due to higher precious-metal content, a monolith quote is typically 2–3 times higher than a classic ceramic catalyst.
How to identify
- Physically larger than a classic catalyst
- Often two substrate sections (catalyst + filter)
- Heavy — between 4 and 12 kg
- Most often paired with diesel 1.5–3.0 dCi/HDi/CDI/TDI engines
Most often found on
- Mercedes-Benz W211, W212 (CDI)
- Toyota Avensis, Auris (D-4D)
- Peugeot 407, 508, Citroën C5 (HDi)
- BMW 5 series, X3, X5 (diesel engines)
Precious metals
High Pt and Pd content, Rh on selected models. The most profitable for recycling.
