Solidification techniques encapsulate hazardous waste into a solid material of high structural integrity. Encapsulation involves either fine waste particles, microencapsulation, or a large block or container of wastes, macroencapsulation (Conner 1990). Stabilization techniques treat hazardous waste by converting it into a less soluble, mobile, or toxic form. Solidification/stabilization (S/S) processes utilize one or both of these techniques.

The goal of S/S processes is the safe ultimate disposal of hazardous waste. Four primary reasons for treating the waste are to:

• Improve handling characteristics for transport on-site or to an off-site TSD facility

• Limit the mobility or solubility of pollutants contained in the waste

• Reduce the exposed area allowing transfer or loss of contained pollutants

• Detoxify contained pollutants
