## Abstract

Apparatus for the treatment of volatile material(s) in contaminated material(s) including a retort assembly which includes a rotatable retort disposed at least partially within a combustion chamber with a heater to indirectly heat the contents of the rotatable retort. A feeder feeds the contaminated material(s) to the retort. The apparatus further includes a pathway for passing contaminated material(s) to the retort and a conduit for passing the combustion gases from an afterburner to the retort assembly to provide additional heat for heating the contaminated material in the retort. The apparatus may also include a high temperature filter which can filter the volatiles before entering the afterburner.
