The correct classification of waste soil can save a significant amount of money; conversely, the incorrect classification of waste soil can affect the success of a project.
Waste classification using proprietary software and the results of contamination testing allows the classification of the waste to be determined, i.e. whether it is hazardous or non-hazardous waste, and European Waste Catalogue (EWC) codes to be provided.
Waste Acceptance Criteria (WAC) testing is then undertaken to determine at what designation of landfill site the soil may be disposed.
Correct Waste Classification Saves Costs
Waste classification was undertaken on surplus soil at a residential development site in Exeter.
The soil had been purchased and imported to be used as capping beneath road surfaces for the new development. However, the material was later found to be unsuitable for the proposed use.
The soil had initially been classified by others as hazardous waste, due to the presence of loose asbestos fibres within the soil matrix. However, following intensive (and representative) sampling of the soil stockpiles, Ruddlesden geotechnical were able to confirm that the soil was non-hazardous waste.
Classifying the waste properly, in accordance with Environment Agency guidance, saved the client significant costs, which would have been incurred if the soil were to have been taken to a hazardous waste landfill, as was originally proposed.
