The waste was considered a special waste on the basis of its high leachable heavy metal content. Envirotreat were able crush and treat the waste with an E-Clay specifically suited to the stabilisation of heavy metal contamination, producing a material that met local landfill criteria, this resulted in a significant saving to the client.
