Abstract

The present invention relates to an apparatus and method for processing of waste involving a volumetric reduction of waste materials. There is an apparatus for processing waste material comprising a compaction compartment for receipt of waste material, the compaction compartment have a screw vane (19) for processing waste material through the compaction compartment and a waste material outlet. The apparatus comprises a heating zone (30) including an arrangement for heating the waste material received from the waste outlet, the apparatus further comprising a cooling zone (70) including a cooling arrangement for cooling the waste material received from the heating zone.
