EWC 19 07 covers landfill leachate: the liquid that percolates through waste and collects at the base of landfill cells. Entries: 19 07 02* (landfill leachate containing dangerous substances) and 19 07 03 (landfill leachate not containing dangerous substances). Hazardous classification depends on landfill type, waste type deposited and leachate composition.
Leachate from active municipal waste landfills contains dissolved organic carbon, ammonium nitrogen, heavy metals, chlorides and inorganic salts. Young leachate (first 5 years) is typically high in BOD, COD and VFAs (volatile fatty acids) from active anaerobic degradation. Mature leachate (after 10+ years) shifts to humic-dominated, lower BOD but persistent organics and metals. Composition changes continuously over landfill lifetime.
Leachate from hazardous waste landfills contains contaminants specific to deposited waste — heavy metals, chlorinated solvents, aromatic hydrocarbons, inorganic salts. These leachates are classified 19 07 02* and require specialist treatment. On-site treatment is most common; some sites tankage leachate to off-site industrial wastewater treatment plants.
Typical Generators
Established valorisation pathways for EWC 19 02 06, ranked by economic value and market depth.
Leachate treated on-site by activated sludge (ammonia nitrification/denitrification), coagulation/flocculation (heavy metal removal), membrane filtration (reverse osmosis for dissolved organics) and UV disinfection. Treated effluent discharged to watercourse or sewer under permit.
Small landfill sites tankage leachate by road tanker to municipal or industrial wastewater treatment plant for co-treatment. Pre-treatment to remove ammonia spikes and inhibitory substances may be required. Discharge agreement with WWTP operator required.
Leachate recirculated back through active waste mass in bioreactor landfill design. Enhances biodegradation rate, reduces leachate treatment demand over time and accelerates landfill gas generation. Permitted approach in several MS under site-specific IED conditions.
These are the established routes for EWC 19 02 06. Which one your stream qualifies for depends on its composition, volume and region.
