Adheres to organic waste. The aerobic microorganisms are sent to the decomposition promoting tank together with the organic waste with the flow of the supernatant liquid, and oxidatively decompose the organic matter in the organic waste in the tank. Therefore, when a plurality of decomposition promoting tanks are provided, the supernatant liquid having a reduced organic matter content flows into the subsequent decomposition promoting tank, and the odor disappears.
