Abstract
Seven-Eleven, the Japanese biggest franchiser of convenience stores, is making efforts to reduce wastes and to enhance recycling activities in all phases of production, transportation and retailing. Recognizing that the residues in food factories are potential and promising resources, Seven-Eleven is trying to put such materials to better use as animal feed in particular. Expertise and a lot of experiments are needed at the same time, and a commercial enterprise is being achieved by means of collaboration with hog breeders, experimental stations and universities.
