We conducted a survey about the feasibility of introducing MBT (Mechanical Biological Treatment) systems for waste incineration facilities linked with sewage treatment facilities. We focused on this topic because the decline of Japan’s population has caused the need of expanding service area of waste treatment facilities and optimizing the efficiency of energy use. From the questionnaire surveys distributed, we received 64 responses from waste incineration facilities, mainly in cities designated by government ordinance, and 78 responses from sewage treatment facilities. Our analysis results showed that 4.7% (3 cases) of incinerators and 3.8% (3 cases) of sewage treatment facilities have the possibility of installing both incinerators and sewage treatment facilities, which is unprecedented in Japan. Municipalities with more frequent communication between departments tended to choose the same pattern we offered, suggesting the importance of inter-departmental cooperation.
