To dispose of waste, there are methods such as landfill, incineration, recycling, and sea discharge. Since the landfill wastes accumulate, there is a limit to the landfill site to accommodate them. In this paper, a time series analysis and current status of landfill allowance was analyzed over 20 years of landfills distributed throughout the country using GIS to understand the status of waste reclamation. As a result, the emissions of waste were gradually increasing, and as the emissions increased, the amount of landfill increased. The landfills in the Seoul metropolitan area have been saturated and need to be resolved as soon as possible.

폐기물 매립층의 침하는 매립 폐기물의 조성특성의 영향으로 인하여 침하특성이 일반 흙의 토질역학적 거동과 다르게 나타난다. 폐기물의 침하특성은 매립당시 나타나는 폐기물 하중에 의한 침하특성과 향후 장기적으로 유발되는 생화학적 침하특성을 구분하여 규명하는 것이 필요하다. 본 연구에서는 국내 대표적 매립지 폐기물 침하에 대한 계측자료를 바탕으로 역학적 일차 압축침하와 생화학적 이차 압축침하에 대한 침하특성계수를 산정하였다. 또한 Sower(1973)의 매립지 폐기물에 대한 침하량 산정식을 응용하여 다단형 매립지 폐기물에 적용할 수 있는 침하량 산정식을 구성하였다.

Large-scale simulated lysimeter experiments were conducted for 4 years as a fundamental study to develop enhanced landfill stabilization method, which accelerate stabilization time and make efficient practical use of self-purification capacity of pollutants in semi-aerobic solid waste landfill. The amount of TOC(total organic carbon) decomposition increased as the landfill depth increased. In case of T-N(total nitrogen), the self-purification capacity increased linearly with the landfill thickness until it reached a maximum level of 6 m. Beyond this level, the self-purification capacity was not increased. The results from lysimeter experiments indicate that 6m of landfill thickness is optimum for self-purification capacity of pollutants considering the mass balance of TOC and T-N.

When some structures are constructed over the sanitary landfill, the waste should be treated by means of replacement and other ways. Otherwise, various problems like a ground contamination, settlement, reduction of bearing capacity and others may be generated. To find out the optimal method of treatment, the properties of the ground have to be inspected. In this study, the preliminary investigation was conducted to find out the characteristic of this site which is considered as insanitary waste landfill. Furthermore, the shape and the amount of the waste was investigated by subsurface investigation like a boring and sampling methods. In addition, the degree of ground contamination and disposal method of refuse was examined.

In order to make use of finished municipal landfill as a construction site, it is necessary to consider environmental and geotechnical aspects for the ground improvement and application of waste landfill. In environmental aspect, methods for management of landfill gas and leachate have to be established, and in geotechnical aspect, it is necessary to investigate available method for constructing structure foundation. In this study, the finished landfill was selected for pilot test. Investigation about the environmental characteristics of the waste landfill was performed to establish the methods far management of landfill gas according to monitoring the gas quantity and to investigate economical efficiency according to utilizing landfill gas. Investigation about cases of utilizing the waste landfill in Korea and abroad as construction site was performed and pilot tests were performed to analyze the improvement effects of methods such as dynamic compaction method and PG pile method available to waste landfill. The results of this study showed that economical profits could be gained by utilizing landfill gas and improved waste landfill, besides, dynamic compaction method was effective in case of improvement depth being shallow, and PG pile method was effective in case of improvement depth being deep.

An information management system for a solid waste landfill site was developed, in this study, to optimize the operation and management of solid waste landfill in real time in addition to provide the information of landfill status to the landfill operator, public official concerned and local residents. The landfill information management system is composed of two systems (Solid waste landfill history management system and landfill operation and performance management system). The solid waste landfill history management system based on automated RFID/LPR system allows landfill operators to provide information of waste collection vehicles and received waste. In addition, the system aids in the identification of 3-dimensional (3D) position for landfilled solid wastes. Using the landfill operation and performance management system based on 3D laser scanner delivers information about landfill volume, settlement, landfill density, and current landfill capacity to landfill operators in real time, resulting in optimum space utilization. Ultimately, this system would dramatically reduce exposure of landfill operators to hazardous materials and improve the productivity of landfill operations.

산업의 발전과 함께 산업폐기물이 늘어나고 있고 이 폐기물의 처리방법 중 가장 일반적이고 많은 사례가 매립이다. 폐기물을 매립할 때 필요한 것이 복토재인데 우리나라에서 복토재로 사용이 가능한 흙은 매립장을 건설할 때 발생되는 잔토와 건설현장에서 발생되는 흙, 하천의 준설토 등이 있다. 하지만 모든 흙을 모두 복토재로 사용할 수는 없는데, 건설현장의 잔토는 건설폐기물로 분류되어 지정매립장에 매립을 해야 하고 하천 준설토는 2차 오염의 방지를 위해 복토재로 사용할 수 없도록 법으로 금지되어 있기 때문이다. 이런 규제는 복토재용 흙을 안정적으로 확보할 수 없게 하고 수요만큼의 공급이 불가능하게 되어 불법적인 사용 가능성을 암묵적으로 인정하는 현실로 이어졌다.

In waste repository environment, we can process the waste history efficiently for reuse by recording the history trajectory of the vehicle which loaded waste and the dumping position of the waste vehicle. By mapping the unloaded waste to 3D and by extracting the dumping point, a new method was implemented so as to record the final dumping position and the waste content under various experiments. In this paper, we developed the algorithm which tracking the vehicle and deciding the moment of dumping in landfills. We first trace the position of vehicle using the difference image between current image and background image and then we decide the stop point from the shape of vehicle route and detect the dumping point by comparing the dumping image with the image that vehicle is stopping. From the camera parameters, The transform method between screen coordinate and real coordinate of landfills is proposed.

In this paper, we constructed the systematic management and standardization of computerized landfill bringing system in Ansung landfill facility. During the system design process and database construction, we considered the specific items in Ansung landfill facility. And, we systemized and conventionalized the basic core data so as to we apply to another landfill facilities. And, we tried to standardize the system using the exception logic for specific items. For this purpose, we developed the landfill bringing management system which can help to manage a landfill efficiently. Basically We made efforts to standardize it's system architecture but also we considered it's localization to adapt An-sung Landfill's special requirements. We used RFID and LPR systems to distinguish a garbage truck from the others, and could establish more reliable landfill management system with this information. We expect that we can perform the systematic and the efficient landfill Bringing using the automated process of bringing in and taking out the waste process based on the developed system by automated RFID/LPR system.
