EWC 19 11 covers wastes arising from the re-refining of waste oil into base lubricant oil or other petroleum products. Sub-entries: 19 11 01* (spent filter clays), 19 11 02* (acid tars), 19 11 03* (aqueous liquid wastes), 19 11 04* (wastes from cleaning of fuel with bases), 19 11 05* (sludges from on-site effluent treatment containing dangerous substances), 19 11 06 (non-hazardous sludges), 19 11 07* (wastes from flue gas scrubbing) and 19 11 99 (wastes not otherwise specified).
Waste oil re-refining converts used lubricating oil into base oil for blending into new lubricants. The main re-refining processes — hydrofinishing, acid treatment, solvent extraction (Recyclon process) — generate characteristic residues. Acid tar (19 11 02*) from sulphuric acid treatment of oil is a highly hazardous residue containing PAHs, organics and acid; its management is a significant challenge for the industry.
Spent filter clays (19 11 01*) from clay filtration of treated oil are classified hazardous due to oil content and adsorbed PAHs. These clays can be regenerated thermally, reducing disposal requirements. The WFD prioritises re-refining of waste oil over other recovery methods, recognising the circular economy value of returning used lubricants to base oil.
Typical Generators
Established valorisation pathways for EWC 19 02 07, ranked by economic value and market depth.
Spent filter clay (19 11 01*) regenerated at 500–600°C in rotary kilns, burning off adsorbed oil and organic content. Regenerated clay returns to re-refining process. Combustion gases treated for PAH; regenerated product tested for residual contaminants before re-use.
Acid tar (19 11 02*) neutralised with lime to produce a less hazardous sludge. Treated material may then be co-processed in cement kilns (organic content as fuel, mineral fraction incorporated into clinker) or stabilised for hazardous landfill. Some acid tars treated by biological processes.
Highly contaminated 19 11 residues not amenable to treatment disposed at hazardous landfill after stabilisation to meet WAC. Ongoing monitoring of historic acid tar lagoons (legacy disposal sites) required under Landfill Directive post-closure obligations.
These are the established routes for EWC 19 02 07. Which one your stream qualifies for depends on its composition, volume and region.
