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 EU Decision (2003/33/EC), but it may also be able to accept small quantities of Inert Waste. Hazardous landfill sites cannot accept Non-Hazardous Waste. There are some restricted circumstances in which Non-hazardous Landfill can accept Hazardous Waste, these are described further below.

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 Stabilised Non-Reactive Hazardous Waste or Gypsum Waste (normally plasterboard) is to be disposed of.

Capacity Hazardous Landfill

The capacity of Hazardous Landfill is reported by the EA for England and is summarised in the graph and table below. Capacity for Hazardous Waste is split out into 'Restricted Sites' by the EA which totaled 722,708 cubic meters in 2015 and 832,407 cubic metres in 2019, dropping to 809,640 cubic metres in 2020. Note that Hazardous Landfill also provides Inert Landfill capacity in the sense that these waste are used for daily cover and site engineering purposes.

The number of 'Hazardous Restricted Landfill' (ref. L06) sites in England in 2020 was 5, with no change on 2019. The number of 'Hazardous Merchant Landfill Sites' (ref. L01) and summarised in the graph and table below totaled 12, a drop of 1 since 2019.
