Consideration of Decarbonization Through Methane Fermentation of Waste Potatoes

Short Introductive summary

In order for Japan to achieve carbon neutrality by 2050, the energy field decarbonization guidelines indicate that decarbonization using gas energy such as biogas is essential. In this report, in order to decarbonize the industrial and consumer sectors, where decarbonizing energy is particularly difficult, we investigated biogasification through methane fermentation using organic residues such as waste potatoes generated from factories. It was confirmed that approximately 70 NL of biogas could be obtained from 1 g of organic residue by performing methane fermentation using organic residue discharged from a factory. Based on these results and the amount of food residue currently generated within the factory, we found that replacing the city gas used within the factory with biogas would reduce CO2 emissions by approximately 300t-CO2 per year.
