SIL process was designed for high plasticity and high moisture content wastes, e.g., sludge, soft clay, and soil. The process employs ZA's patented ZA-H series reagents, which stabilize pollutants present in the wastes and solidify the soft waste into strong particles to improve its engineering properties. After SIL treatment, the geotechnical performance of the treated soft wastes will be greatly improved and the environmental impact will be minimized.
SIL's formulations and processes can be customized to suit the nature of different wastes e.g. wastewater sludge, marine clay, excavated clay, sediment, soil, etc.
The SIL process consists of mechanical pretreatment, batching, mixing, granulation, and curing. The process is flexible, scalable, and robust.
