Abstract
Anaerobic digestion (AD) is one of the activities to create a sustainable society. AD has a function of waste treatment that removes an organic matters and it is able to take energy out of biogas and utilize it. However, AD is focused on its function of waste treatment and energy recovery/utilization is not sufficient in some cases. Therefore, a continuous operation test of biogas generation has been conducted by using food waste from a sauce factory. This test aimed to create a sustainable and labor-saving system with energy recovery/utilization by a cogeneration system. As a result, it achieved the compatibility of a capacity of waste treatment with energy recovery/utilization and operated for 6000 hours continuously and automatically. Furthermore, there is a surplus of energy balance as the generated electricity (l56kWh/day) exceeds the electricity from the grid (63kWh/day) in daily data.
