This method of collecting and processing the excrement makes it inconvenient to collect and transport the excrement, and in the case of unauthorized discharge, it causes serious environmental pollution.

Moreover, in a mobile public toilet, when excrement is accumulated in summer, a severe odor is generated and most people avoid using it because it is unsanitary.

In order to solve this problem, there is known a method of decomposing by fermenting the excrement by mixing the microorganisms with sawdust, etc. and then putting it into the excreta bin of a public toilet.

In Patent Document 0001, when urine is passed through a toilet seat, urine is transferred to and stored in the urine storage tank by the operation of the controller, and when feces and urine are seen together, urine is stored in the urine storage tank and feces are supplied by the operation of the controller. In this mixed state, it is transported and stored to the compost storage, and as the compost is progressed by the supplied sawdust, urine is not transferred to the compost storage side, so composting is easy and the drying time can be greatly shortened, improving productivity and work efficiency. It can be greatly improved, and as compost production using feces is made by sawdust and microorganisms, there is described a compost manufacturing system using feces that can produce eco-friendly compost, but the patent document 0001 is complex that is difficult to apply to a mobile toilet. It is difficult to apply to a portable toilet because it has a structure and a severe odor is generated in the process of composting.
