This paper considers major three steps to arrive at accurate baseline emissions against which actual emission reductions attributable to CDM projects are accounted for. The first step is to select most likely baseline scenario among plausible alternatives. Then, the additionality of the project in question would be assessed by demonstrating that the project is not included in the baseline scenario selected. Finally, baseline emissions are calculated under the baseline scenario. In this paper, these three steps are integrated into a single flow chart in order to help understand the procedures for application of a baseline methodology better. Following the flow chart, a landfill gas-to-electricity project in Korea is analyzed as a case study. In consequence, this paper concludes that landfill gas-to-electricity projects in Korea have great potential for CDM projects, and it could also be concluded that data availability and reliability are a prerequisite for successful application of baseline methodologies for landfill gas projects to Korean specific situations.

The study is carried out to survey the proper management and to propose an eco - friendly separation system through efficient screening and resource recovery of excavated materials containing waste from various excavating fields such as reconstruction of landfill sites for reuse, reclamation of unsanitary landfill and residential land development of waste dumping sites. The current status and screening process and analytical characteristics of the excavated materials containing waste were reviewed. Through the analysis of the samples such as separated combustibles, recyclable soils and residues collected from the on-site visits we were able to understand the characteristics of separated materials and excavated materials containing waste such as calorific value, elementary composition, TOC, foreign material content and LOI. It has been found that elimination of the moisture of excavations, removal of attached soil from the surfaces of the excavated combustibles and the quantitative supply method of the input devices are the main operating factors as essential factors for the optimal separation of excavated materials containing waste. For efficient management and recycling of excavated materials containing, it is necessary to set criteria of ash content in separated combustibles and criteria organic matter content in separated soils.

Green infrastructure projects have the potential to reduce global warming and deliver sustainable energy solutions. Recently, the construction industry has been expanding their portfolios in New and Renewable (NRE) projects. However, the economic feasibility of NRE projects have not been validated and construction companies are not acquainted with their associated risks. This research performed a two-tiered feasibility study of the domestic projects registered for CDM in the UNFCCC. The first phase involved calculating the average IRR and NPV of the domestic CDM projects, which showed that their profitability to be very low. In the second phase, four NRE projects (Solar, Wind, Hydro, Landfill Gas) were selected and additional income generated from Feed-in-Tariff and CER sales were added to determine the improvements in the projects' IRR and NPV. Results indicate that Solar and Landfill Gas projects benefited the most from the two support mechanisms, while benefits to Wind and Hydro projects were minimal. While the Landfill Gas project had the highest IRR, the Wind project was the most investment attractive due to its NPV and minimal dependency on FiT and CER sales. Construction companies should enter into NRE projects with a long term view as related technologies mature.

Recently, the reclamation of public waters has been on a downward trend due to environmental problems, but there is a limitation to evaluating environmental characteristics index uniformly. In this study, the stability of settlement behavior on public waters reclaimed land was analyzed using the experimental test. From the primary consolidation influence factors, the characteristics of the waste lime was similar that of clay in process of consolidation. Assuming that the waste lime landfill is the layer reinforced with thin geosynthetic reinforcement, the settlement was predicted by calculating the amount of increase using the Westergaard method. As a result of predicting settlement with degree of consolidation, it was found that the increase in stress was reduced by 40% when the surface layer of the soft ground was reinforce with geotextiles compared to the case where it was not reinforced. In addition, the consolidation behavior characteristics of clay and waste lime were compared using the correlation between the plasticity index and internal friction angle of waste lime. Since the waste lime in the public process of consolidation, it was predicted that long-term settlement will increase further.

본 연구에서는 현재 사용 종료된 매립지 재사용을 위해 정비를 실시 중인 전국 매립지 중에서 충남 공주시 금홍동에 위치한 사용 종료된 매립지를 대상으로 하여 사업 지구 및 그 주변지역의 환경질 평가를 위하여 토양에 관한 오염도 조사를 실시하였다. 시료는 매립지 내 1개 지점과 주변 논 2개 지점, 밭 1지점으로 총 4개 지점에서 채취하였다. 토양시료의 분석항목은 토양환경보전법에서 제시하는 총 11개 항목으로 하였으며, 실험방법은 토양오염공정시힘방법에 준하여 실시하였다. 실험결과 토양환경보전법상 농경지에 대한 우려기준과 비교하여 전 항목이 기준에 크게 미치지 못하는 것으로 나타났다. 토양질의 면에서 된다면 이 매립지 부지는 일반적인 용도의 토지로써 사용이 가능하다고 사료된다.

The world largest land reclamation project in the name of Saemangeum(Ariul) from 1991 to the present has been implementing in a part of the west coast of Korea. In the Saemangeum reclamation project, the large-scale project cost is used for the landfill reclamation. A number of landfill reclamation methods have been studied in order to reduce the large-scale cost of the Saemangeum project under construction. There are many studies related to the on-site real-time monitoring with mobile systems for operating a wide range of landfill. In order to apply the work method for efficient cost-savings in the landfill operations to the Samangeum project, this paper develops a mobile management system that is composed of a mobile interface module, a data server module for data transmission and storage, and an analysis server module to analyze the input data and derive the results. The mobile system is designed by analysing user's and system requirements, functional interactions, and data flow using unified modeling language(UML). The user interface is developed for the on-site real-time monitoring through the status and related attributes of land reclamation by using the digital maps of the Samangeum coverage via mobile devices. Finally, a mobile management system would be developed that can provide a 3D GIS service based on the Dry Internal Project Site Digging Reclamation Method(DIPSDRM).

This study was conducted to evaluate air injection mode on stabilization of landfill gas and to predict the time for landfill mining. It took 8 times longer for pulse aeration to get to aerobic condition, compared to continuous aeration. It was evaluated that continuous aeration mode is more preferable than pulse mode for rapid air exchange in landfill mining. High correlation ($r^2$ = 0.95) was found between continuous aeration time and time to maintain aerobic condition when $0.2m^3/min$ of air was continuously injected and stopped. The aerobic condition ($CH_4$ < 5%) was maintained for 1.5 times longer than aeration time.
