초록

Since 2005 the landfilling of food waste has been prohibited, and many recycling facilities (private, domestic, animalfeed conversion, public composting) have been constructed and operated as waste-treatment centers. However, due to the negative attitude of users on the domestic animal feed and compost produced from food waste, the byproducts of waste have created a vicious cycle, needing treatment themselves. In addition, the London Convention prohibited the discharge of organic waste such as sewage sludge into the ocean in 2012 and of food-waste leachate in 2013. An alternative to landfilling and incineration is to treat biomass with anaerobic digestion. However, the anaerobic-digestion efficiency of the Daejeon City bioenergy facility, which has adopted a mixed digestion process of food waste and food waste leachate, has not been reproduced in other municipalities due to a misunderstanding of anaerobic digestion and a lack of operating skill. Thus, the anaerobic-digestion efficiency of the bioenergy facility in Deajeon is analyzed, and it provides basic information for the anaerobic co-digestion of organic wastes.
