Abstract
Disclosed are systems and methods for treating contaminated material. The material is heated by nonconductive and nonconvective heating in a vacuum chamber such that the surface of the material is heated without significant heating of the air within the chamber. The surface of the material is heated to at least a volatilization temperature of the contaminants or to a decomposition temperature of one or more compounds in intimate contact with the contaminants, so that the concentration of contaminants in the material is reduced. Exhaust is removed from the chamber and cooled. A solids and/or liquids collector removes condensed solids and/or liquids and has a gas outlet connected to a vacuum pump.
