Fish Offal Recycling (Soka City, Saitama Prefecture) - October 1997

Sankiku Feed Industries Co., Ltd., located in Soka City, Saitama Prefecture, collects approximately 300 tons of fish offal (including intestines, bones, and heads) annually from Tsukiji Market (now Toyosu Market) and the Yokohama Central Wholesale Market. The company processes this material into high-protein livestock feed using high-temperature drying and grinding technology. This process prevents spoilage and unpleasant odors, and the resulting feed has earned high praise as a feed for pigs and chickens. The recycling initiative has reduced disposal costs by more than 10 million yen annually, contributing to food loss reduction and improved local sanitation. Furthermore, through product development utilizing calcium and protein, the company is contributing to the creation of a circular economy and the reduction of environmental impact.
