Abstract
Segregation of food scraps from general households and resource recovery have succeeded in Oki-machi, Fukuoka prefecture. Previous studies focused on the reduction of waste, but this study focused on multidimensional aspects, specifically agriculture. By methane fermentation of food scrap, human waste and septic tank sludge, and using the digestive juice as a fertilizer for around 100ha of farm land, the farmers could reduce chemical fertilizer cost by about 9.5million yen. The farm products are sold at a nearby farm stand and served at restaurants, etc, resulting in more than 200 million yen in sales and an increase in local enrollment of 26 people. This circulation project was also highly praised by the town people.
