Abstract
This study was conducted for the purpose of examining stable disposal of foodwaste and possibility of multilateral use of its by-product by mixing earthworm powder and by-product generated from food waste disposal for making feed for sea fish. As a result of the study, content of crude protein (25.93%, 69.72%), crude lipid (16.91%,6.39%) crude ash (15.38%, 5.30%) in by-product of food waste and earthworm powder was higher than that in fish meals manufactured in the country, and it was judged that it is available to make good feed as a source of fatty acid as it contained C18:1n9c, 1n9t and c16:0. As for stability as a raw material for feed, it was shown that the stability was high when using the product as a raw material for feed not exceeding the standard of test items, and though change of content and ingredients to mixing ratio, it was shown that mixed specimen of fertilizer (S6) was higher, showing that it has great utilization in the future. Also, as it has more content of registered ingredients than any other raw materials for feed manufactured in the country, it is possible to be used as a substitute when manufacturing feed for sea fish. Therefore, it is judged that various studies such as economic analysis and technology of possible manufacturing will be needed in the future.
