Solidification-stabilization technique soils

Solidification/Stabilization technologies are techniques designed to be used as final waste treatment. A major role of these processes is posttreatment of residuals produced by other processes such as incineration or chemical treatment. In some cases, solidification/ stabilization processes can serve as the principal treatment of hazardous wastes for which other detoxification techniques are not appropriate. High volume, low toxicity wastes (such as contaminated soils) are an example of this application. 

Metal(loid)-contaminated soil can be remediated by chemical, physical, or biological techniques (or a combination of all three). The technology applied is often specific to the metal(loid) contaminant to be removed and the site characteristics and may be further classified into in situ and ex situ categories. In situ remediation takes place on site and does not require excavation of the contaminated soil, limiting the exposure pathways to other organisms, including humans. Many in situ teclmiques aim to stabilize the metal(loid) fraction in the soil via specific soil amendments (e g., lime), vitrification, electrokinetics, solidification (thermal treatments) or passive remediation methods. Such techniques do not reduce the total...
