VALUE: £520,000

The licensed waste lagoon at the former Albion chemical works was filled with an alkali sludge with mercury contamination. In order to surrender the Waste Management Licence and mitigate risk to Controlled Waters, Celtic applied stabilisation / solidification to some 17,000m3 of the sludges. Robust feasibility and validation testing confirmed mitigation of risk and enabled surrender of the licence.

Close out was achieved by demonstrating that solidified / stabilised material met leachate targets for a suite of metals including mercury, TPH and cyanide.
