Abstract
Organic liquid-like hazardous waste is loaded with a sorbent in a container including interior and exterior compartments. The container is supplied to a rotary incinerating kiln. The waste is loaded in the container and the compartments are arranged so that the waste in the exterior compartment is initially vaporized in the kiln without the waste in the interior compartment mixing and being vaporized with the waste in the exterior compartment. The waste in the exterior compartment acts initially as a thermal and mass transfer barrier to prevent initial vaporization in the kiln of the waste in the interior compartment to substantially delay the vaporization of the waste in the interior compartment relative the vaporization time of waste in the exterior compartment and relative to the time when the waste in the interior compartment would have been vaporized if the container did not include the compartments.
