An apparatus and method for the efficient removal of hazardous and nonhazardous volatile and semi-volatile organic materials from contaminated materials includes an evaporation/vacuum heating chamber that communicates with a microwave generator, a vacuum pressure system, a contaminated material in-feed system, and a residue removal system. The evaporation/vacuum heating chamber is fed with successive batches or a continuous supply of contaminated material and subjects the contaminated material to microwave energy and vacuum pressure to draw off volatile and semi-volatile material from the contaminated material as vapor and reduce the contaminated material to a dry residue. The vapors are drawn from the chamber by the vacuum pressure system and are condensed and collected. The dried material residue is removed from the chamber by the residue removal system and is also collected for later disposal or reuse. The apparatus operates continuously or in a batch mode, with contaminated materials being fed into the apparatus simultaneously with the distilled vapor and dried residue being removed from the chamber.

A method of separating volatile and semi-volatile material from non-volatile materials by thermal desorption, the method including: continuously supplying materials into an enclosed volume; rotating the materials supplied in the enclosed volume around a fixed vertical axis; subjecting the materials supplied into the enclosed volume to microwaves and vacuum pressure as the materials are rotating inside the enclosed volume; and continuously removing the materials from the enclosed volume after the materials have been rotated and subjected to microwaves and vacuum pressure.
