Solidification Plant

Stabilisation and solidification aim to immobilise the toxic constituents of scheduled wastes to prevent them from leaching from the wastes once disposed. The Solidification technologies are often used to treat the residues from other treatment processes such as fly ash from incineration or sludges from heavy metal precipitation. Cement, lime and sand are also used in the solidification process. Solidification technologies are effective in treating a variety of difficult to manage inorganic wastes.

At Solidification Plant, inorganic wastes that are typically metal hydroxide sludge containing heavy metals such as lead, arsenic, nickel, zinc and chromium which do not fulfil the Direct Landfill Waste Acceptance Criteria for direct disposal into Secured Landfill are treated. This Plant can be used for wastes containing mixtures of contaminants and can economically treat large waste volumes.
