Get contacts for EWC 08 02EWC 08 02 covers wastes from coating types other than liquid paint — principally ceramic glazes and enamels (08 02 01 — waste coating powders), powder coatings, thermal spray coatings and functional coatings (PVD/CVD, sol-gel). Sub-code 08 02 02 (aqueous sludges containing ceramic materials) is non-hazardous; 08 02 03 (aqueous suspensions containing ceramic materials) is also non-hazardous. Hazardous classification applies if heavy metal content exceeds WFD thresholds.
Ceramic glaze waste arises at tile, sanitaryware and tableware manufacturers — raw glaze residues, spent application equipment washings and off-specification glaze batches. Glazes contain metal oxides (ZnO, BaO, SrO, Co₂O₃, NiO) as colourants, and lead oxide in traditional formulations (now phased out). Powder coating overspray is efficiently recovered in electrostatic application booths — recovery rates >99% in modern booths, making actual waste volume very small.
Thermal spray coating waste (tungsten carbide/cobalt, chrome carbide/NiCr powders) arises from overspray and used blast media. WC-Co thermal spray waste contains cobalt — classified as CMR (suspected carcinogen, Cat. 2) and potential hazardous waste. Powder coating dust classified as combustible dust — requires dust explosion assessment under ATEX Directive 2014/34/EU.
Typical Generators
Established valorisation pathways for EWC 08 02, ranked by economic value and market depth. Powder coating overspray recovery is the primary route.
Electrostatic powder coating overspray recovered from booth via cyclone and cartridge filter system. Recovered powder blended with virgin material at 10–20% addition rate for non-critical applications. Colour-change waste (mixed powder) collected separately and disposed.
Ceramic tile glaze residues (sludge from glaze grinding mills) recycled as secondary raw material in body formulation at ratio ≤5% to avoid colour contamination. Raw glaze batches segregated and returned to glaze preparation. Lead-free glazes: wastewater sludge disposed to inert landfill.
WC-Co thermal spray waste containing >1% Co assessed as hazardous (CMR-driven). Cobalt content recovered by hydrometallurgical processing (leach + precipitation) where volume warrants. Residual stabilised with cement binders and disposed to hazardous landfill after WAC testing.
These are the established routes for EWC 08 02. Which one your stream qualifies for depends on its composition, volume and region.

Key legislative frameworks governing EWC 08 02 classification, transport, and treatment.
Powder coating overspray classified as ST1 combustible dust (Kst ≤200 bar·m/s). ATEX zoning required for recovery systems. Booth cleaning procedures must prevent dust accumulation. Explosion suppression or venting systems required on recovery cyclones.
Cobalt compounds (CoO, CoCl₂) in thermal spray and ceramic pigments are SVHCs under REACH. Cr(VI) in chrome plating and some spray coatings subject to REACH Annex XIV authorisation from 2024. Coating waste composition analysis required before disposal.
Ceramic glaze waste containing Pb, Cd, Cr(VI), Co above WFD Annex III threshold concentrations classified hazardous. Traditional lead-containing glazes (now rare) always classified 08 02* hazardous. Lead-free glaze waste typically non-hazardous after characterisation.
