Since the present invention is configured as described above, it has the following functions and effects. First, a predetermined amount of a microbial decomposition promoting material is charged from the charging port, and organic waste is further charged. Then, when the processing cylinder is rolled, the microbial decomposition promoting material and the organic waste in the processing cylinder are stirred by being stirred up by stirring blades on the inner peripheral surface of the processing cylinder. The organic waste is additionally charged into the processing cylinder until it reaches a predetermined ratio with respect to the volume in the processing cylinder, and is stirred and mixed by rolling the processing cylinder again. Next, the processing cylinder is set upright on the ground or the like, and left as it is. At that time, the microorganism decomposition promoting material and the organic waste mixed by stirring are appropriately compressed by their own weight. Therefore, microbial decomposition is efficiently performed in the processing cylinder. Therefore, according to the present invention, since the driving rotation by the shaft portion is not performed unlike the prior art, the structure is simple, the watertightness is good, the operation is simple and the cost is low, and the microorganisms can be efficiently decomposed. Can be promoted. Further, according to the second aspect, since the charging port is provided substantially at the center in the axial direction on the outer peripheral surface of the processing cylinder, when the processing cylinder is rolled, the introduced microbial decomposition promoting material and the organic waste are charged. Can be dispersed in the axial direction and efficiently stirred and mixed. Therefore, microbial decomposition can be promoted more efficiently. The inlet is provided so as not to protrude from the outer peripheral surface of the processing cylinder, so that when the processing cylinder is rolled, the rotation thereof is not hindered. In addition, according to the third aspect, the processing cylinder is rolled on a plurality of rotatable rollers, so that the space for rolling the processing cylinder can be reduced. Further, according to the fourth aspect, it is possible to provide a method for treating organic waste which is simple in operation and promotes efficient microbial decomposition. In addition, according to the fifth aspect, the amount of the microbial decomposition promoting material and the organic waste with respect to the internal volume in the processing cylinder and the amount of air in the processing tank are easily diffused and mixed in the processing cylinder and promote the microbial decomposition. Since the ratio is adjusted to a suitable ratio that facilitates the microbial decomposition, it can be more efficiently promoted.
