These include tank bottom sludges, oily water separator contents, spent process catalysts, acid sludges from alkylation units, and contaminated clay from lube oil finishing.
Refinery sludges contain recoverable hydrocarbon fractions (20–60% oil by weight) alongside water and inorganic solids. Centrifugal and thermal desorption technologies recover the oil fraction for reprocessing, reducing hazardous waste volumes by 60–80% while generating a saleable hydrocarbon product.
Spent hydroprocessing and FCC catalysts contain significant concentrations of transition metals (Mo, Ni, V, Co, W) deposited during operation. These are the highest-value fraction in refinery waste, processed by specialist catalyst recyclers (BASF, Umicore) to recover metals as secondary raw materials for catalyst re-manufacture.
Typical Generators
Established valorisation pathways for EWC 05 01, ranked by economic value and market depth. Spent Catalyst Metal Recovery is the primary route.
Spent hydroprocessing (HDS/HDN) and fluid catalytic cracking (FCC) catalysts processed by specialist recyclers via hydrometallurgical or pyrometallurgical routes to recover Mo, Ni, V, Co, W. Recovery efficiencies: Mo 90–95%, V 85–92%, Ni 80–88%. Gate fee: negative (recycler pays for high-grade spent catalysts).
Oily sludges from tank bottoms and API separators processed by thermal desorption at 300–500°C to recover hydrocarbon fraction (25–55% of feed). Recovered oil returned to crude unit or sold as secondary fuel. Residual solid (<1% oil) co-processed in cement kilns. Gate fee: €40–80/tonne input sludge.
Non-recoverable fractions (acid sludges, contaminated clay) incinerated in permitted high-temperature hazardous waste incinerators meeting IED Directive Chapter IV emission standards. Gate fee: €150–400/tonne.
These are the established routes for EWC 05 01. Which one your stream qualifies for depends on its composition, volume and region.

Key legislative frameworks governing EWC 05 01 classification, transport, and treatment.
Most 05 01 sub-codes classified hazardous (*). Mirror entries apply where hazardous character must be assessed against Annex III properties (HP1–HP15).
Refinery operators classified as producers of hazardous waste; duty to ensure waste passed only to authorised collectors and treatment facilities. Consignment note system mandatory.
Most crude oil refineries are upper-tier Seveso sites. Waste management procedures must be incorporated into site Safety Management Systems and emergency plans.
Industry good practice for petroleum waste minimisation and recovery documented in IPIECA/API/IOGP Joint Industry Position Paper on Waste Management.
