ABSTRACT:
A method is provided for the treatment of contaminated materials such as impounded sludges and contaminated soils by thermal desorption wherein a solid matrix is subjected to the action of superheated steam in a closed vessel, a gas stream comprising superheated steam is recirculated to the vessel and recirculation of the superheated steam is continued until organic constituents are separated therefrom to predetermined concentrations that are environmentally insignificant and within the limits prescribed by governmental regulations.
