초록

With the increase in food consumption, the amount of animal and plant residues in food manufacturing has continued to increase. In particular, the residues generated from food manufacturing industries have a high recycling value because they are generated in large quantities, are homogeneous, and their recycling costs are less than that of households or small restaurants. In this study, we selected industries that produce large amounts of homogeneous animal and plant residues, including manufacturers of animal oils and fats, vegetable oils and fats, starches and glucose or maltose, and conducted material flow analysis using statistical data, field surveys, and questionnaires. In the results of material flow analysis, the amount of raw materials used in the surveyed industries was 3,029,830 tons per year, and 8,487 tons of animal and plant residues were generated through manufacturing and processing. In addition, the import substitution effect of recycling byproducts from industries into animal feed or similar was estimated to be ₩847,007 million KRW per year.
