Get contacts for EWC 03 02 02*EWC 03 02 02* is a specific sub-code under EWC 03 02 — Wood preservation wastes. The classification guidance below applies to this waste stream.
EWC 03 02 covers residues from industrial wood preservation: process sludge from treatment plant sumps, spent preservative solutions, wood chips and shavings contaminated with biocides, and tank cleaning waste. The hazardous classification of specific sub-codes (03 02 01*, 03 02 02*, 03 02 03*, 03 02 04*, 03 02 05*) depends on the preservative system used — creosote, copper-chrome-arsenic (CCA), boron compounds, organic biocides or other chemicals.
Creosote-treated wood generates highly hazardous waste containing polycyclic aromatic hydrocarbons (PAHs). CCA-treated wood contains chromium(VI), copper and arsenic and is banned for new residential use under Biocidal Products Regulation but remains in service. TPAC (triazole/pyrethroid/azole combinations) and boron treatments generate lower-hazard residues. The EU Biocidal Products Regulation (EU) 528/2012 governs active substances permitted in wood preservatives, with several historic preservatives phased out under REACH.
Industrial symbiosis options are limited due to contamination: creosote-treated wood is restricted to energy recovery in permitted installations; CCA-treated wood requires thermal treatment with controlled ash management. Non-hazardous treatment residues (boron-based, some azole treatments) may be managed via non-hazardous waste routes. The end-of-life management of existing stock of CCA-treated utility poles is a growing challenge across EU Member States.
Typical Generators
Established valorisation pathways for EWC 03 02 02*, ranked by economic value and market depth.
Creosote and CCA wood waste incinerated in permitted installations under IED, ensuring flue gas treatment meets emission limit values. Ash from CCA-treated wood is hazardous and requires specialist disposal. Some cement kilns co-process non-hazardous treated wood fractions under waste-derived fuel permits.
Contaminated treatment sludge and heavily impregnated wood that cannot be thermally treated economically is disposed at permitted hazardous waste landfill meeting Directive 1999/31/EC Article 6 acceptance criteria after pre-treatment.
Non-hazardous treatment residues (boron compounds, water-based preservatives) may be managed as non-hazardous industrial waste. Sawdust and chips from boron-treated timber can be composted or used as biomass fuel subject to verification of preservative type and concentration.
These are the established routes for EWC 03 02 02*. Which one your stream qualifies for depends on its composition, volume and region.
