In the near future, it is expected that the amount of waste will decrease because of the decreasing trend of the population. On the other hand, a large amount of waste is generated by disasters like giant earthquake and heavy rain. In order to deal with both of the scenarios, it is necessary to make the treatment facilities flexible. This study focused on finding the optimal scale of wide area waste management from an economical point of view about Miyazaki prefecture in Japan. In order to know the cost of domestic waste treatment and disaster waste treatment, the study has used several model formulas. The domestic waste cost and disaster waste are calculated by three multiple regression formulas: collection and transporting cost model, intermediate treatment cost model and final disposal cost model. According to the similar researches in the past the models need the large amount of time and data, so the model is not able to be used in wide area waste management model. Take that into consideration, the model I used consists of simple formulas, therefore the model is able to calculate waste disposal cost in wide area.
