A questionary survey was conducted to investigate citizen's attitude to treatment facilities of municipal solid waste in Miryang during 8. June of 1998 and 22 June of 1988. Collection effiencies was 86.7%, as 260 individuals of the 300 individuals. The survey showed that 43.0% of answers recognized seriousness of problem of the waste treatment and 33.1% of respondents concerned about recycle of organic waste. 40.8% of total answers said that they most hated landfill site among waste treatment facilities, and most citizens wanted as much distant as possible from waste treatment facilities. It was investigated that the greater part of respondents wanted the greatest compensation. About 58% of respondents was opposed to complete waste treatment facilities. 36.2$ among answers wanted establishment of waste treatment facilities in an industrial complex or an industrial area. The majority of respondents was willing to increase recycle rate and recognized seriousness of landfill site security. The majority of citizens do not trust environmental administration of Miryang City and they think that democracy and open of administration need for overcome MINBY.

According to the National Fire Agency, there are 1,810 waste recycling facilities, 2,094 waste treatment facilities, and 223 waste minimization facilities in Korea. Waste fires are characterized by high severity and are prone to reignition, and it is difficult to timely detect them. Waste fires consequently demand many firefighters, equipment, and time to extinguish. Notwithstanding this reality, waste is excluded from the category of special combustible materials in the Act on Installation and Management of Firefighting Systems, 2021 (the Act). Therefore, this study proposes that special combustible materials, including waste, should be incorporated into the Act, that fire detectors and photoelectric smoke detectors should be installed to enable early detection of fires, and that the use of water and foaming agents as firefighting equipment should be enforced.

Concentrations of the principal volatile organic compounds, such as benzene, toluene, ethylbenzene, m,p,o-xylene, styrene, and chlorobenzene were measured at the solid waste treatment plants classified into four categories; municipal waste incinerator, municipal waste landfill site, industrial waste incinerator and industrial waste landfill site. The average concentration of VOCs in industrial waste treatment facilities was 33.43 ppb and was significantly higher than that measured at municipal waste treatment facilities (4.71 ppb). The average toluene concentrations measured at incinerators (13.05 ppb) were a little higher than those measured at landfill sites (11.54 ppb). The contribution of the waste treatment facilities to the concentration of benzene (0.35 ppb) and o-xylene (0.15 ppb) in the industrial area was relatively small. However, toluene measured in the industrial waste treatment facilities was the most abundant VOCs with the average concentration of 21.37 ppb. As a result of analyses of fingerprint, in cases of IISH and ILUS, a variety of compounds other than major VOCs were detected in high level. On the Pearson correlation analysis, the correlation was generally positive and some pairs of these VOCs were very strongly correlated (correlation coefficient > 0.75).

The method of residential waste and food waste collecting is changed into automatic waste collection(AWC) system from direct collection by human resource. To solve the problem caused by odour from AWC facilities, the structure of input facilities, conveying pipes and collecting facilities have been changed into closed and sealed construction to enclosed the facilities and collect odour efficiently. Based on cases and experiences, to treat variable odour matters which are caused by food waste, chemical cleaning method is preferable method to cope with odour caused by food waste.

Waste to Energy Plant were recognized as hateful facilities, and there were many conflicts in the location due to social problems such as the NIMBY phenomenon due to problems such as damage to property in the surrounding area, odor, and image loss. Problems such as air pollution and odor are solved by the development of advanced prevention facilities such as electric dust collectors, wet cleaning systems, semi-dry reaction towers, bag filters, and catalyst towers (SCR: Selective Catalytic Reduction), and air recycling facilities in waste storage tanks. However, it is being avoided because of the perception that it is an incinerator. To resolve these conflicts, the government installs and operates resident convenience facilities to compensate residents near resource recovery facilities, provides green space and improves the environment, and supports heating expenses in accordance with the 「Waste Treatment Facility Support Act」. The purpose of this study is to derive implications through the analysis of domestic and overseas case studies for resident convenience facilities and environment improvement for the promotion of local communities in resource recovery facilities and use them as basic data for community promotion and environmental improvement when installing resource recovery facilities in the future.

The current study relates to RADAR (RAdio Detection and Ranging) application for level measurement of vitrified radioactive liquid nuclear waste. The vitrification of radioactive liquid waste is carried out in special equipment called 'Melters'. The study is directed towards the design and frequency modulation used in the level measurement of vitrified waste. More specifically, the RADAR design and frequency used for level measurement in a melter. This level measurement technique can also be used for dynamic vitrification process and can be used to measure the level variations without using any external medium/material and using only electromagnetic waves. Also, this technique is durable and accurate even under the high radioactive environment present inside the melter.

The purpose of this study is to estimate the economic valuation of rural waste disposal facilities that are one of the rural environmental improvement projects using contingent valuation method(CVM) in Gyongsangbuk-do, Korea. This study surveyed 1,089 households about the WTP(Willing To Pay) of rural waste disposal facilities policy in Gyongsangbuk-do and it was composed with city level and town level. The overall results show that the respondents well accepted the contingent market and would be willing to pay(WTP) a significant amount for the proposed policy program of rural waste disposal facilities. The values estimated for the rural waste disposal facilities are as follows : 1. The maximum WTP was \10,466 in City level and it was \9,104 in town level by per year. 2. The mean WTP was \9,257 in City revel and it was \8,636 in town lever by per year. 3. Total economic benefits for the household amounted to \7,989,046,270 per year. This result can be used to useful base data fir the policy programs of rural waste disposal facilities.

Despite the continuous installation and regular inspection of waste treatment facilities, complaints about excessive incineration and illegal dumping stench continue to occur at on-site treatment facilities. In addition, field surveys were conducted on the waste treatment facilities currently in operation (6 type) to understand the waste treatment process for each field, to grasp the main operating factors applied to the inspection. In addition, we calculated the material·energy balance for each main process and confirmed the proper operation of the waste disposal facility. As a result of the site survey, in the case of heat treatment facilities such as incineration, cement kilns, and incineration heat recovery facilities, the main factors are maintenance of the temperature of the incinerator required for incineration and treatment of the generated air pollutants, and in the case of landfill facilities Retaining wall stability, closed landfill leachate and emission control emerged as major factors. In the case of sterilization and crushing facilities, the most important factor is whether or not sterilization is possible (apobacterium inspection).In the case of food distribution waste treatment facilities, retention time and odor control during fermentation (digestion, decomposed) are major factors. Calculation results of material balance and energy resin for each waste treatment facility In the case of incineration facilities, it was confirmed that the amount of flooring materials generated is about 14 % and the amount of scattering materials is about 3 % of the amount of waste input, and that the facility is being operated properly. In addition, among foodwaste facilities, in the case of an anaerobic digestion facility, the amount of biogas generated relative to the amount of inflow is about 17 %, and the biogas conversion efficiency is about 81 %, in the case of composting facility, about 11 % composting of the inflow waste was produced, and it was comfirmend that all were properly operated. As a result, in order to improve the inspection method for waste treatment facilities, it is necessary not only to accumulate quantitative standards for detailed inspection methods, but also to collect operational data for one year at the time of regular inspections of each facility, Grasping the flow and judging whether or not the treatment facility is properly operated. It is then determined that the operation and management efficiency of the treatment facility will increase.

In order to democractically resolve the "not-in-my-backyard" (Nimby syndrome) which is widespread in Korea, the policy of the Ministry of Environmnt(MOE) is that the MOE is willing to negotiate with local inhabitants who refuse to allow the establishment of waste treatment facilities, and that such facilities will be safety and effectively constructed and managed. According to this policy, the MOE has developed a basic plan to construct 255 incinerators by the year 2001, and establish 42 sanitary landfill sites and 5 specific waste treatment facilities in 1994.s in 1994.
