Abstract

The amount of food waste was estimated for each prefecture in Kanto region, then CO2 mitigation potential by the policy scenarios including feedstock recycling, composting and methane fermentation was evaluated. As the result, all policy scenarios, assuming dry heat system in feedstock recycling and utilization of wastewater as liquid fertilizer in methane fermentation, can mitigate GHG emissions. Moreover, the long-term utilization potential of urban wet waste for methane fermentation in Japan was projected under the socio-economic scenarios until 2050, then 3.7MWh of electricity production was estimated in 2050.
