EWC 19 02 covers wastes arising from physico-chemical treatment of industrial wastes including dewatering, neutralisation, precipitation, flocculation and solvent stripping. Sub-entries: 19 02 03 (non-hazardous premixed wastes), 19 02 04* (premixed wastes containing at least one hazardous substance), 19 02 05* (sludges from physico-chemical treatment containing dangerous substances), 19 02 06 (non-hazardous sludges), 19 02 07* (separated oils and concentrates from separation), 19 02 08* (combustible liquid wastes containing dangerous substances), 19 02 09* (combustible solid wastes), 19 02 10 (non-hazardous combustible wastes), 19 02 11* (other wastes containing dangerous substances) and 19 02 99 (non-dangerous wastes not otherwise specified).
Treatment sludges from precipitation of heavy metals (hydroxide precipitation of Cr, Ni, Zn, Cu from electroplating effluents) are the dominant volume. Sludge composition reflects input waste stream — copper hydroxide sludge from PCB manufacture; nickel hydroxide sludge from metal finishing. These sludges may have secondary metal recovery value when concentrations are high.
Separated oils from oil/water separators and decanting operations (19 02 07*) represent recoverable fuel or re-refining feedstock. Combustible waste fractions (19 02 08*, 19 02 09*) may be processed into SRF for energy recovery, reducing overall landfill volumes from treatment facilities.
Typical Generators
Established valorisation pathways for EWC 19 08 14, ranked by economic value and market depth.
Heavy metal hydroxide sludges from precipitation treatment filtered, dried and smelted for base metal recovery. Copper, nickel and zinc sludges with sufficient metal content accepted by non-ferrous smelters as secondary raw material. Metal recovery gate fee lower than hazardous landfill.
Combustible solid and liquid waste fractions (19 02 08*, 19 02 09*, 19 02 10) blended and processed into solid recovered fuel (SRF) meeting EN 15359 specification. Co-fired in cement kilns or power plants under IED co-incineration permit conditions.
Low-metal sludges not viable for recovery stabilised with cement-based binders to immobilise heavy metals and reduce leachate toxicity. Stabilised product disposed at hazardous landfill after WAC testing under Landfill Directive 1999/31/EC.
These are the established routes for EWC 19 08 14. Which one your stream qualifies for depends on its composition, volume and region.
