Hazardous Landfill
Only a Hazardous Landfill can accept Hazardous Waste for Landfill Disposal but only then if it meets the relevant standards for engineering and management controls and Waste Acceptance Criteria set out in the Annex to the Decision, but it may also be able to accept Non-Hazardous Waste and Inert Waste.
There are numerical limit values for leachable inorganic substances, organic content along with standards for physical stability. These exist for both granular and monolithic hazardous waste.
Standards require Hazardous Waste that is disposed of with other Non-hazardous Waste to be in separate engineered cells within the Landfill where stable non-reactive Hazardous Waste or Gypsum waste is to be disposed of[1].
