EWC 19 03 covers stabilised or solidified wastes resulting from waste treatment processes. Sub-entries: 19 03 04* (wastes marked as hazardous, partially stabilised), 19 03 05 (stabilised wastes not covered by 19 03 04), 19 03 06* (wastes marked as hazardous, solidified), 19 03 07 (solidified wastes not covered by 19 03 06). Stabilisation reduces leachability; solidification improves handling characteristics.
Stabilisation/solidification (S/S) involves mixing hazardous waste with cement, lime, pozzolanic materials or proprietary binders to chemically immobilise contaminants and reduce permeability. The process does not destroy contaminants but converts them to less mobile forms. Treated product must meet WAC before landfill under Landfill Directive 1999/31/EC.
Partial stabilisation (19 03 04*) retains hazardous classification because immobilisation is incomplete or treatment does not achieve WAC. Full stabilisation meeting WAC produces 19 03 05, which may be disposed at non-hazardous landfill, significantly reducing disposal costs. Quality management and routine leachate testing are essential to verify classification.
Typical Generators
Established valorisation pathways for EWC 19 04 02, ranked by economic value and market depth.
Partially stabilised hazardous waste (19 03 04*) disposed at permitted hazardous landfill meeting WAC for hazardous cell. Monofill cells for specific waste types may be operated at certain facilities. Landfill gas monitoring and leachate collection required under Landfill Directive.
Waste achieving full stabilisation and meeting non-hazardous WAC reclassified 19 03 05 and accepted at non-hazardous landfill. Significant cost saving over hazardous landfill disposal. Continued leachate monitoring at landfill confirms ongoing immobilisation performance.
Solidified wastes meeting aggregate performance specifications used as engineered fill in civil engineering under controlled conditions. Application requires site-specific risk assessment for contaminant mobility. End-of-waste status unlikely without robust national criteria.
These are the established routes for EWC 19 04 02. Which one your stream qualifies for depends on its composition, volume and region.
