## Description
The scope of the Shaft and Silo Decommissioning Project is to design, build and carry out the operation of the facilities for retrieval, treatment and packaging of the Shaft and Wet Silo waste contents.
The finalised scheme design of the Process Cell includes a series of independent Plant items that provide the means to sort, segregate and size reduce the Wet Silo and Shaft solid waste and batch that waste into 200L drums ready for downstream assay and packaging for long-term safe storage.
The Process Cell Plant also separates and collects the corresponding Liquid and Sludge Waste, and conditions it to produce a concentrated sludge waste stream that is metered into modified 200L drums pre-filled with cement powders. The Liquid Waste is further filtered, and the subsequent grey water is re-used within the Process Cell before being ultimately discharged to the downstream Effluent Treatment Plant.
