Ocean dumping of all of the land waste was banned from 2014 by the London Convention. Therefore, the development of new technology to handle the huge amount of food waste are urgently sought. In particular, we were able to handle the garbage by using the Hermetia illucens by 2013 Presidential Decree. During this situation, we've been studied how to remove food waste by using Hermetia illucens as Environmentally harmless insect. In this study, four kinds of sample as a food waste, pork, bean-curd and boiled rice and mixed waste were selected. We tried to find efficiencies with different type we selected respectively. Efficiency of pretreated food waste with the form of the porridge was compared to rarefood waste efficiency.
