Classifying Waste Slurry for Disposal

We recently visited a local stonemason in Northamptonshire to undertake waste classification of the waste stone slurry created during the stone cutting process.



Hand samples were collected of the stone slurry, and the processes in the Environment Agency’s WM3 were followed in order to classify the waste slurry for disposal. The waste slurry was tested for a range of contaminants (including metals, inorganic substances, PAHs, BTEX, TPH, asbestos) before a Hazard Assessment Screen was undertaken to initially establish whether the waste slurry was considered hazardous or non-hazardous. Single stage Waste Acceptance Criteria (WAC) testing was also undertaken on the waste slurry sample to classify the waste further for landfill disposal. An EWC (European Waste Catalogue) code, also known as the waste classification code or LoW (List of Waste) code, and recommendation on the landfill tax for the waste slurry were also provided for the Client.  If you need help with classification of waste soil from your site send us an email or contact us on 01280 816409
