EWC 16 08 covers spent catalysts from a wide range of chemical and refining processes. Sub-entries include: 16 08 01 (precious metal catalysts — gold, silver, platinum group), 16 08 02* (spent catalysts containing dangerous transition metals or compounds), 16 08 03 (non-hazardous transition metal catalysts), 16 08 04 (spent FCC catalysts — fluid catalytic cracking), 16 08 05* (spent catalysts containing phosphoric acid), 16 08 06* (spent liquids used as catalysts) and 16 08 07* (spent catalysts contaminated with dangerous substances).
Platinum group metals (PGMs: Pt, Pd, Rh, Ru, Ir, Os) in autocatalysts and refinery catalysts represent significant recoverable value. Hydrocracking catalysts contain molybdenum, nickel and cobalt; their spent form may be classified hazardous due to leachate toxicity. FCC catalysts contain rare earth elements and zeolite substrates with lower recovery value.
Spent catalyst characterisation requires sampling protocols that account for heterogeneous distribution of metals and contamination. Pyrophoric spent catalysts (those that ignite spontaneously on air exposure) must be passivated before transport. Carrier gas purging and inert atmosphere handling required for certain refinery catalysts.
Typical Generators
Established valorisation pathways for EWC 11 01 11, ranked by economic value and market depth.
Autocatalysts and PGM-bearing industrial catalysts smelted and chemically refined to recover platinum, palladium and rhodium. Secondary PGM recovery displaces primary mine production. Refiner issues metal credit against assayed PGM content.
Hydrocracking and reforming catalysts leached to recover nickel, cobalt, molybdenum and vanadium. Recovered metals sold as secondary raw materials to specialty metal producers and catalyst manufacturers.
Heavily contaminated catalysts with insufficient metal value for economic recovery stabilised with cement or pozzolanic binders. Treated material disposed at hazardous landfill meeting WAC under Landfill Directive 1999/31/EC.
These are the established routes for EWC 11 01 11. Which one your stream qualifies for depends on its composition, volume and region.
