Should you wish to move your soil off a site, then under to the EU Waste Framework Directive ‘your intention is to discard a material’ and the material becomes classified as a waste. Even if you have someone who wants the material, it remains classified as a waste…!
A waste can only be classified as either Hazardous or Non-Hazardous. Please note that “Inert” is NOT a waste classification.
To undertake a waste classification chemical analysis of the material in question is required. There is guidance as to the amount of analysis required for the volume of soils. Ideally a review of the full site investigation report is also required to establish the type of material; former usage of the site; PSD of the material; information from the borehole logs; etc.
Once the material has been appropriately classified (Haz or Non-Haz) then and only then does the WAC information come in to play. The WAC is then used to establish whether the ‘waste’ material is suitable for disposal in to either a Hazardous or Inert landfill site. Non-Hazardous landfill sites do not require a WAC report.
Where you have material that complies with ‘U1 Use of waste in construction’ (Environment Agency) or Table 11 of schedule 1 to the Waste Management Licensing (Scotland) Regulations 2011, it may be possible to use these materials where a construction use can be proven
