The current application is directed to systems and methods for processing organic waste using aerobic bacterial digestion of organic waste. In one implementation, the system includes a covered enclosure with a non-porous floor and sidewalls within which a floor-scraping, helical auger with serrated or toothed edges is mechanically powered and translated in two dimensions in order to chop, mix, lift, and move composting organic waste towards a discharge end of the enclosure. The vessel additionally includes a rotatably mounted screen, in one implementation, for screening the composted organic waste as it is discharged. The vessel additionally includes, in one implementation, perforated, pressurized tubes for introducing pressurized air into the organic waste as it is processed as well as a flexible water hose for introducing moisture into the organic waste as it is being processed. Various sensors are employed to monitor and control the moisture, temperature, and other physical parameters of the organic waste by controlling rotation and translation of the helical, floor-scraping auger and, in certain implementations, controlling the pressure of pressurized air input into the perforated, pressurized tubes and the rate of water flow to the flexible water hose.
