[ What is claimed is:] [7.] A process for breaking down waste comprising the steps of:providing a pressure vessel encased by a heating jacket and having a rotatable central shaft disposed along the length of the pressure vessel and a plurality of paddles extending from the central shaft towards the walls of the pressure vessel;loading waste into the pressure vessel;sealing the pressure vessel to allow pressurization of the pressure vessel;providing heat to the heat jacket to heat the walls of the pressure vessel thereby increasing the temperature and pressure inside the pressure vessel;rotating the shaft at a rate of 50 revolutions per minute (RPM) or less so that the paddles mechanically causes the waste to contact the heated walls of the pressure vessel; andcutting waste with a cutting edge carried on the wall of the pressure vessel in an upper region thereof.
