This decontamination process is an on-site physical and chemical extraction technology for cleaning organic pollutants and metals.

It is a segregation process which aims to separate out the finer fraction of contaminated soils which normally are associated with the majority of the pollution and then where possible treat these chemically to reduce the volume of contaminated material that may still require disposal. It can be used to treat a wide range of material types including gravel, sand, silt, and sediments but is not generally suitable for soils with greater than 30% fines content. The process plant is such that volumes of 10,000t of soil requiring treatment are generally required before the technology becomes cost effective.
