This study is conducted to find out problems of the public food waste recycling facility and its improvement. Through a research on the actual condition, it is possible to analyze the problem of operation. Moreover, for this improvement, with analysis of the current state of recycling rate including its generation and the problem that can be shown from the real operation of the public/private food waste recycling facility, the results are as follows: It can be shown that the current amount of domestic food waste resource recycling is about 97 %. Almost every public recycling facility is analyzed to be economically infeasible and is not for recovery but to simple disposal. Especially, most of Biogas facilities appeared that amount of production and demand is not appropriate differed from enforcement design.

This study is conducted to find out the problems of the public food waste recycling facility operation and its improvement. In order to save the national budget by analyzing plans to expand including operation rate for the food waste recycling facility, the alternative ways are suggested. The result can be as follows: Policy switch is required not only to save budget and stable disposal of food waste but also to promote resource recycling rather than expanding public facilities. In order to change the policy for stable and eco-friendly disposal of food waste, it is necessary to adopt semipublic system that prevent the decline of the rate of operation of private resource recycling facility. Furthermore, it is required to prepare both qualified technologies of public resource recycling and the ways of profitability secure.

Korea has recently implemented two m메or policies on organic wastes, including food wastes. One is the Volume-Based waste Fee System (VBWFS). which went effect nationwide in January 1995, and the other is a ban on the landfill of organic wastes, such as food wastes. organic sludge, and animal manure, in accordance with the Waste Management Act. These two policies have brought about remarkable positive effects, including the reduction of organic wastes at source, and the development of technology for recycling food wastes into feed and compost. However, they have caused obstacles to carry out the policy on food wastes, in areas of legal and technological infrastructures for recycling. Therefore, this study intends to find problems of policies for recycling food wastes, and to suggest ways to resolve them.

This study is conducted to find out the problem of the public food waste recycling facility and its improvement. By using an operation status analysis, an economic analysis was done to check up on its feasibility in comparison with an investment in the food waste recycling facility currently in use, thereby proposing the possible alternatives to prevent the national budgets form wasting with witless construction of the new facilities. As a result, it is considered necessary to come up with an effective plan for establishing the public resource facility, strengthen criteria for government subsidies being used up on the public resource facility, and enact an independent law of the food waste.

After the introduction of Volume-based Waste Fee System for municipal wastes, the disposal of food wastes became an issue an issue in society. Concerted efforts among government agencies have been made to manage food wastes separately from municipal wastes. For example, the Ministry of Environment, the Ministry of Agriculture and Forestry, and the Ministry of Health and Welfare established the '5-year('98-'02) Basic Plan for Recycling Food Wastes' in September 1998. Also changes in the waste disposal system has been sought, aiming at the Resource-circulating Society.

As the national income level is improving, housing urbanization and economic speed are progressing rapidly, household waste and food waste are rapidly increasing. The "Waste Management Act" (founded in 1991) introduced the volume-based household waste system in 1995, and even after implementation, the odor of food waste and the prompt disposal process continue to be a social problem.For this reason, the food waste recycling business is attracting attention. In this paper, regarding the role of resource recycling such as feed, compost, and other resources of food waste, this thesis aims to reduce the inefficiency of the recycling process. Data Envelopment Analysis (DEA) of the relationship between inputs and outputs of 33 facilities nationwide, excluding facility data (insufficient) among 394, (238 public, and 156 private ones), as of the end of 2020, which is running a domestic resource recycling project This study was conducted to investigate the important role in the relative management performance of food waste recycling facilities.It was hypothesized that the influence of business history, facility capacity, capital, and machinery of a company running a food waste recycling business on sales was tested.

음식물류 자원화 사업은 버려진 음식물 폐기물을 재가공하여 이를 자원으로 활용하는 사업으로 현재 정부와 민간, 그리고 지자체에서 적극적으로 추진하고 있는 사업이다. 그러나 음식물류 자원화 시설의 운영성과와 효율성은 제각각이며, 이에 대한 정확한 분석이 이루어지지 않고 있다. 이에 본 연구에서는 음식물 자원화 사업의 효율적이고 효과적인 수행에 필요한 기초자료를 제공하기 위하여 음식물 자원화 사업에 대하여 이론적으로 정리하고, 음식물 자원화 사업의 현황을 살펴보고자 한다. 이를 통하여 향후 음식물 자원화 사업의 추진에 필요한 음식물 자원화 시설의 효율성 평가를 위한 방법론을 제시하고자 한다.

This study refers to the composting of DDM Environmental Resource Center, which is operating abnormally in the food waste public-resource facilities that are operating nationwide, in accordance with the initial operating conditions. Similar process cases were investigated to examine issues concerning unusual composting facilities in DDM environmental resource centers and to analyse the causes of the issues. In addition, several improvement measures and alternatives for converting abnormal driving facilities into normal driving facilities may be proposed, and major abnormal driver provisions that are highlighted as issues during field application may be resolved.

The leachate recirculation anaerobic digestion system has the advantage of stable methane gas generation compared with existing one phase systems. In this study, an anaerobic digestion system fed with source separated food waste from school cafeteria was studied with different food waste/inoculum anaerobic sludge volume ratios (8:2, 3:7, 2:8). From this study, leachate recirculation anaerobic reactor with food waste/inoculum anaerobic sludge volume ratio of 2:8 that is 9 gVS/L of OLR(Organic Loading Rate) had the highest gas production. Also this anaerobic reactor showed daily decrease of H2S and NH3 contents in produced gas. Average biogas yield was 1.395 m3 Biogas/kg VS added. Other anaerobic reactors with food waste/inoculum anaerobic sludge volume ratio of 8:2 and 3:7 stopped methane gas production.

This research was performed to evaluate the food waste recovery facility using optimization performance index. In 2014, the generated amount of food waste occupied approximately 27% in total municipal solid waste. The 97.2% of the food waste was recycled and the others were treated through landfill and incineration in the portion of 0.9% and 1.9%, respectively. In food waste recovery facilities of year 2014, the composting and feed facilities were 49.5% and 22.9%, respectively. The feed facility showed higher scores in all technological, environmental, and especially economical evaluations than those of composting facility. As results of overall optimization performance index, the feed facility has higher score of 61.5 than 52.7 of composting facility. It was demonstrated that the feed facility has the advantage, compared with the composting facility.
