Solidification and Stabilization

Solidification is a technique that encapsulates hazardous waste into a solid material of high structural integrity. Solidifying fine waste particles is termed microencapsulation; macroencapsulation solidifies wastes in large blocks or containers. Stabilization technologies reduce a hazardous waste's solubility, mobility, or toxicity.

Solidification and stabilization are effective for treating soils containing metals, asbestos, radioactive materials, inorganics, corrosive and cyanide compounds, and semi-volatile organics. Solidification eliminates free liquids, reduces hazardous constituent mobility by lowering waste permeability, minimizes constituent leachability, and provides stability for handling, transport, and disposal.
