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.

1. A high temperature filter for use in the treatment of volatile gaseous contaminated material, the filter including a main body having an internal space therein which internal space includes an upper region and a lower region, said internal space being separated into first and second chambers, an opening providing communication between the chambers, said opening being at the lower region of the internal space, an inlet for delivering the gaseous contaminated material to the first chamber in the upper region of the internal space, an outlet for discharging the gaseous material from the second chamber in the upper region of the internal space, a solids collection zone adjacent the opening, a solids discharge outlet for discharging solids from the solids collection zone, a baffle directly opposite to and spaced from the inlet upon which incoming gases impinge so as to separate the solids from the gaseous material, filter means for filtering the gaseous material passing out of the second chamber via the outlet and a heat jacket which at least partially surrounds the main body of the filter.
