A thermal treatment reactor for feedstocks and method of use. The thermal treatment reactor comprises an infeed assembly, a furnace, a rotary drum, a discharge assembly, and a liberator assembly. The rotary drum may comprise forwarding flights, mixing flights, oscillating flights, and raking pins. The feedstock to be thermally treated enters the reactor through the infeed assembly. The feedstock is fed into the reactor in a controlled manner by means of a screw conveyor system. The thermally-treated product exits the reactor via the discharge assembly, which separates the thermally treated product into a VOC liberator, from whence the product enters into a cooling system to reduce the temperature for safe storage and handling.
