ことを特徴とする、有機性廃棄物の発酵処理方法。1. An organic waste is mixed with a reconstituted material containing fermenting bacteria and charged into a primary fermenter, hot air is supplied to the waste to promote fermentation, and then, in the primary fermenter. The waste is transferred to the secondary fermentation tank, hot air is supplied to promote fermentation, then the organic product fermented in the secondary fermentation tank is transferred to the tertiary fermentation tank, and hot air is supplied. Then, in the method for fermenting the organic waste to ferment the organic product, the temperature or water content in the fermenter is measured, and the temperature or water content is preset with the change over time. If the measured change in temperature or moisture over time is different from the change pattern, the flow rate or temperature of the warm air to be supplied is adjusted so that the change pattern is obtained.
