A drum for processing household, commercial solid waste and non-hazardous industrial waste. An inlet wall of the drum includes an opening to allow entry of waste into the drum to be treated. An outlet wall includes an opening for evacuation of treated waste from the drum. Further openings on the inlet and outlet walls provide ventilation, allowing outside air to circulate through the drum and the waste material being processed. A rotating envelope within the drum includes large cutters to tear and separate the waste and small cutters and points to further process the waste and separate the waste into its constituent parts. The large cutters are disposed in a helicoidal shape to advance waste entering the drum at the inlet wall towards the outlet wall for removal.
