  • Municipal and sanitary landfills can pose environmental problems due to leachate, landfill gas md unstable geotechnical properties. Most governmental bodies delay the correction of landfill problems or landfill replacement until a crises stage is reached. The replacement of a landfill is often made difficult due to costly regulatory controls, public opposition to siting and the high cost of closure for the previous landfill unit. Solutions to extending landfill life and capacity Involve waste minimization by recycling, refuse compaction and waste-to-energy incineration. Incineration can reduce the volume of refuse by 50-95%. The largest installed bases of municipal waste Incinerators are located in Japan and the U.S. The volume of waste contained in a landfill can be estimated by load count tabulations, weight-and-volume measurements or a material balance analysis based on the trash profile of user categories. for an existing landfill, core samples may be collected and analyzed for use in a material balance analysis. Newly generated refuse contains approximately 50% of the heating value of coal. However, landfill properties vary significantly due to the waste profile of the contributors and biodegradation due to time and weathering. The volume of the Nanji-do landfill

  • It may be necessary to apply a daily fever to operate the municipal solid waste landfill. The daily cover helps to control nuisance factors such as the escape of odors, dusts and airborne emissions, and can control the population of disease vectors. Also it may be reduce the infiltration of rain, decreasing the generation of leachate and the potential for surface water and groundwater contamination. Because of its usual availability and traditional usage as the municipal solid waste landfill, soil remains as the most common daily cover material. However, soil tends to reduce the volume of dumping waste c;3pacity in the landfill, it also reduces a period of using in the landfill. Therefore, it is necessary to research about Alternative Daily Cover Materials (ADCMs) because of the limitation of landfill sites. Recently, The types of ADCMs are classified into geosynthetics, forms, spray-ons, indigenous materials. In this study, the authors have tested the spray type of Alternative Daily Cover(ADC) using by flyash, alum with cement. The development. of ADCMs will be highly effective in terms of prolongation using landfill.

  • As the combination of technique and art, environmental facilities have the function to improve the image of urban green space. Among these facilities, some can be designed and arranged reasonably. But to the facilities of sewage, electricity and sanitation and so on, are usually ignored and become the blemish in the green space. Based on the analysis of the status, taking the design of well cover of sewage as an example, the landscape approaches are discussed from form, material, color and artistic technique and so on.

  • 우리나라의 폐기물 발생총량은 꾸준히 증가추세를 보이는 가운데, 최근 생활폐기물의 처리현황을 보면 재활용이나 소각이 매년 증가하고 있다. 쓰레기 소각율이 높아지고 대형 소각시설이 증가하면서부터 소각 후에 발생하는 도시 소각재의 처리 및 재활용의 문제가 중요한 관심사가 되고 있다. 소각재의 효과적이고 안전한 취급을 위해서는 그것의 화학적 성질에 관한 지식이 중요하다. Kirby and Rimstldt$^{[1]}$ 는 Charlotte (USA)에 소재하는 두 곳의 소각로에서 나온 Municipal Solid Waste (MSW) ash를_체계적으로 분석하여 화학적 조성에 대한 연구를 행한 바 있다. (중략)

  • This paper deals with the result of an analysis on the effect of the power generation by municipal solid waste(MSW)-refuse derived fuel(RDF) and the introduction of tipping fee sharing between RDF manufacturing and power generation project. As a model case for the MSW generated at small and medium cities in our country, an analysis of the RDF power generation and Tipping fee sharing shows that 1) MSW amount of 7,800* $10^3 $t/y could produce 1,950*$10^3$t/y of RDF 2) Electric power generated by MSW-RDF could supply 290,000 households/year and 98,548 C-t/y of $CO_2$ could be reduced. 3) Tipping Fee should be shared by the considering of the contents of project of both side between RDF Production and power generation.

  • In Korea, the number of municipal and hazardous waste incinerators have been increasing since the 1980s. In addition, municipal waste incinerators (MWI) are almost always located in residential areas. Therefore, the human health risk caused by dioxin has become a growing public concern in Korea. In this report, we describe the results of study in which serum levels of PCDDs/PCDFs in a group of workers at the MWI were compared to those in a comparison group of community residents who had never worked at the MWI.

  • This study was carried out to investigate and analyze the citizen's attitude for the issue of the municipal solid wastes in Miryang city. The waste generation rate was decreased by 56% compared with 1991, and 71.8% of generated wastes were treated by landfill method. 61.6% among respondents were contacted waste problem by TV and the majority of respondents felt seriousness of food-waste problem. The majority of people felt that waste discharge decreased after "volume-base charge system" and 71% of total respondents were burdened down with use of volume-base charge envelope. The greater part of citizens answered that they experienced damage due to wastes and satisfied with the collection system but they recognized the necessity of the establishment of collection system and increase of cleaners must be nessary.

  • In woody waste separated from municipal solid waste, medium density fiberboard was major contributors with particleboard, paper, plywood and log, with different composition based on collected period. In chemical compositional analysis of woody waste, it was similar to softwood based on carbohydrate composition analysis. Based on the carbohydrate composition, saccharified solution from MWW could be good resource for biorefinery.

  • Community residents are tend to evade waste treatment facilities such as waste landfills, waste incinerators. Therefore, decision-makers of waste management are concerned about the reduction and recycling of food garbage. As a treatment alternative of food garbage which consists of 30% of municipal waste, producing compost and feed stuff from food garbage is environmentally amenable. In considering the characteristics of food garbage are putrid and high moisturized, methods of landfilling and incineration for food garbage are environmentally inadequate. For the institutionalization of food garbage recycling, separate discharge, establishment of collection system, securing of market for compost and feed stuff manufactured from food garbage, and tax and financial incentives for food garbage recycling facilities are necessary.
