The quantity of waste has been increased due to the increase in population and consumption after industrialization. Accordingly it caused the urban environmental problems, the lack of landfill and the pollution around the landfill. Thus, it is necessary to research the adequate alternative in the long-term. In case of Japan, areas and quantities of landfills at sea are more great than those of landfills in land. And investigating our condition, landfills of the metropolitan area in land are to be fully filled with wastes up to 2020 and be closed. In this research, construction of landfill sites at sea is suggested as the alternative waste disposal method and it is suggested that in our country, the suitable landfill sites of the metropolitan area are the regions around Jangbong-do Island and Muei-do Island. It is expected that the best way to transport wastes is to transport through Kyungin canal from the middle collection center to the lower Han River. Rough cost for construction of landfill at sea, if it is used for 50 years, is expected to be 2 trillion won and total time to construct the landfill is expected to be 10 years. Many studies concerning to this research proposal are to be performed so that construction of landfills familiar to environment are to be accomplished.

인천광역시 서구에는 폐기물ㆍ폐수수탁처리사업장, 사료제조업, 화학ㆍ펄프제조ㆍ주물공장, 축산ㆍ산업 등의 많은 악취유발업체가 산재하고 있으며 더욱이 서울특별시, 인천광역시, 경기도내 수도권에 인접한 13개 시ㆍ군에서 배출하는 폐기물을 처리하고 있는 수도권 매립지가 위치하고 있어 악취로 인한 인근 지역주민의 생활피해와 이에 따른 다발성 민원의 제기 등으로 악취발생의 대책수립에 보다 근본적이고 체계적인 요인분석의 필요성이 무엇보다도 절실하게 요구되고 있다.(중략)

폐기물 오염문제에 대한 국민적 인지도가 높아지면서 폐기물 처리시설에 대한 주민의 반대는 최근 커다란 사회적인 문제로 등장하고 있다. 혐오시설인 매립장의 입지를 반대하는 현상은 개인의 효용을 중시하는 경제주체의 경제행태 논리상 무시할 수 없는 현상이다. 주택가격과 주택까지의 거리와의 함수관계를 파악함으로써 주변지역주민들의 매립장 기피의사를 파악하고자 하였다. 추정결과 주택가격으로 지불하는 금액을 통해서 주민들이 매립장을 피하기 위해 부담하고자 하는 의사는 유의성이 있었다. 비용부담의사는 매립장과 가까이 거주할수록 높았고, 거리가 멀어짐에 따라 감소하는 것으로 나타났다.

To predict the potential reduction of $CH_4$ by recovering several types of wastes as of reusable energy sources like RDF, the $CH_4$ emission for each type of waste from Landfill Site 3 of SUDOKWON Landfill was estimated for the period of 2017 to 2024. Without any recovering effort on types of wastes being disposed of at the Landfill, there are producing a total of $526{\times}10^6\;Nm^3$ of $CH_4$; municipal waste of $337{\times}10^6\;Nm^3$, construction waste of $178{\times}10^6\;Nm^3$, and facility waste of $11{\times}10^6\;Nm^3$. It composed of 41.5% to that observed from 2002 to 2009. With properly retrieved by MT(Mechanical Treatment), it released a total of $158{\times}10^6\;Nm^3$ $CH_4$; $127{\times}10^6\;Nm^3$, $28{\times}10^6\;Nm^3$, and $4{\times}10^6\;Nm^3$, respectively. Additionally, when biologically degradable residues can be fully treated by MBT (Mechanical & Biological Treatment) system, the total amount of $CH_4$ emitted from the site will be lowered down as low as $115{\times}10^6\;Nm^3$, which is comparably lower showing only 21.8% to that for without any energy recovery practice. Futhermore, it is far less showing 9.1% to that obtained from 2002 to 2009. It can be decided that predictable amount of $CH_4$ emission reduced could be successfully accomplished and enhanced through ways of energy recovery efforts such as further scale adjustment of LFG treatment capacity in association with currently implemented practices in the landfill site.

This study was carried out to evaluate the possibility of resource recovery for municipal solid waste(MSW) that sorted by a MBT system. First, physical property of MSW was similar to wastes carried into Sudokown landfill site. However, moisture of MSW was little higher than that. As a result of BMP test using organic fraction of MSW(OFMSWs), approximately 60 ~ 80 mL $CH_4/g$-VS of methane was occurred. Compared to the other studies, the value of methane is lower. It seems to be caused that high ratio of vinyl/plastic in OFMSWs. The other BMP test using sample of MBT system located in Sudokwon landfill was conducted each physical properties. According to the result of experiment, food waste makes 193 mL $CH_4/g$-VS, and paper is 102 mL $CH_4/g$-VS. However, there was not methane production in vinyl and rubber. Additionally, others that can't sort no more show 30 m $CH_4L/g$-VS of methane production. From the result of experimental data OFMSWs has high fraction of vinyl, rubber and other substance that difficult for biodegradation. Therefore it is need to sort of them.

Waste landfills built on weak soils have the possibilities of the failure of slope and foundation due to the disposed waste loads. To ensure the landfill will sustain its stability within a limited site area, it's necessary to investigate and understand the characteristics of soft land by identifying the requirements for waste filling and by quantitative field measurement and management of landfills. In this paper, the stability analyses are performed using the field measurement data of Gimpo #2 Metropolitan Landfil. For the stability analysis, Tominaga-Hashimoto method and Kuriharh method, which may be able to manage the stability of the landfill quantitatively, are used.

The purpose of this study is to analyse whether the waste disposal volume level in the construction waste disposal industry makes a different effect on earnings management behaviour by size of the licensed storage capacity and by location of the waste disposal site. The empirical results of this study are as follows. First, the waste disposal volume significantly influences earnings management behavior. When it comes to the size of licensed storage capacity in the small-sized capacity firms, the smaller waste disposal volume firms make more aggressive earnings management by using discretionary accruals. On the other hand, in the large-sized capacity firms, more waste disposal volume firms report higher earnings by adjusting more discretionary accruals. Second, the effects of waste disposal volume on the earnings management show different pattern depending on the location of waste disposal site. When the firms are located in the non-capital regions, the smaller waste disposal volume firms report higher earnings by adjusting discretionary accruals as well as by using real activities earnings management. However, the firms located in the capital regions show more aggressive earnings management when they have higher waste disposal volume level.
