Waste Soil Classification

It is the responsibility of a waste generator to classify waste soil as non-hazardous or hazardous before it is removed from a site. In addition, correct classification of waste allows informed waste management options to be considered, provides more predictable disposal costs, prevents accidental harm to people and the environment and ensures legal compliance.


Waste classification is not necessary if uncontaminated soil is excavated for use on-site or if contaminated soil is not excavated. It may be possible for contaminated soil to be reused on-site if the CL:AIRE code of practice (CL:AIRE DoWCoP) is followed. We can help with this process.

If waste soils are destined for disposal in a landfill, Waste Acceptance Criteria (WAC) testing will need to be undertaken to confirm an appropriate landfill site is selected.


Contrary to popular belief, WAC testing does not characterise waste as hazardous or non-hazardous. In fact, WM3 states “Landfill WAC analysis (specifically leaching test results) must not be used for waste classification and hazardous waste assessment purposes.”


We provide a full range of waste consultation from initial waste classification (determination of non-hazardous and hazardous waste) in accordance with the Waste Management 3 (WM3), advice on appropriate waste management options including reuse of soils in compliance with the DoWCoP and can provide WAC testing should disposal to landfill be required.
