Abstract: A process and an apparatus for recovering and treating hazardous and non-hazardous components from process streams generated from a continuous system for selectively separating organic and inorganic constituents from contaminated material. The contaminated material is heated to a first temperature sufficient to volatilize water and lower boiling point constituents contained in the material, thereby producing a dried solid material and a first gas containing water vapor and volatilized lower boiling point constituents. The contaminated material is heated in a dryer, which includes an indirect heated hot oil screw dryer having a screw for conveying the material. The first gas is separated from the dried solid material. The lower boiling point constituents are recovered from the first gas.
