In order to reduce the primary energy consumption of newly constructed buildings, insulation, energy conservation, and energy generation are being promoted. Photovoltaic power generation is widely used for energy generation, however the installation capacity is limited in urban apartment buildings due to the small roof area. In this study, the biogas power generation using disposer wastewater was focused on, because the facility can be used in combination with the photovoltaic power generation. The pretreatment and operating condition to realize the miniaturization of gasification equipment were investigated.
