Envirotreat Technologies Limited was engaged by Jehu Construction to provide a treatment solution for approximately 200 tonnes of spent oxide materials (“blue billy”) which had been identified on a development site in Tondu, Bridgend. Envirotreat carried out stabilisation of the “blue billy” utilising a specific E-Clay formulation designed to immobilise the leachable cyanide contamination. The treated stabilised materials were validated against agreed leachate criteria and subsequently reused on site.
