폐기물을 적절히 관리하고 처리하기 위해 기본 자료가 되는 폐기물의 물리적 특성과 화학적 특성 분석을 위해 충주시에서 발생된 생활폐기물을 대상으로 발생원과 매립장에서 시료채취를 채취하여 겉보기밀도, 폐기물의 물리적 조성, 삼성분, 화학적 조성 및 발열량을 조사 분석하였다. 발생원별조사결과와 매립장 반입폐기물의 물리적 특성 값들은 차이가 있으나, 화학적 조성 값은 큰 차이가 없는 것으로 나타났다. 따라서 환경부에서 도입예정인 생활폐기물전처리시설(MBT(mechanical biological treatment))과 같은 폐기물중간처리 장치를 도입할 경우 물리적 조성 값을 알기위해서는 발생원별 조사가 필수적이지만, 소각로 설계를 위한 폐기물조사에서는 주로 화학적 특성 값을 이용하기 때문에 간단히 매립장에 반입되는 폐기물의 분석치만 조사하여도 큰 문제가 없는 것으로 판단된다. 폐기물의 중간처리에 중요한 생활폐기물의 물리적 성상은 가연성과 비가연성 성분으로 분석할 경우 가연성은 연평균 87.4%로 나타났고, 비가연성의 경우 연평균 12.6%이며, 생활폐기물의 발생원별 겉보기 밀도 평균은 0.150ton/㎥이다. 생활폐기물의 삼성분 분석결과 평균은 수분 27.6%, 가연분 60.5%, 회분 11.9%이고, 원소분석 결과 평균 원소성분에 대한 값은 C: 50.1%, H: 6.%, O: 39.5%, N: 1.9%, S: 0.5%, Cl: 1.3%이며, 저위발열량은 2,441㎉/㎏이다. The comparative analysis on physico-chemical characteristics of municipal solid waste from dwelling site and landfill site were performed to provide the fundamental information of waste management in Chungju city. It was analysed and evaluated the bulk density, physical component, three major component, chemical component, and heating value of MSW. The physical components depended on the sampling site in dwelling site and landfill site. But, by the ultimate analysis, the chemical composition was almost similar to result for municipal solid waste from dwelling site and landfill site. Therefore, it is necessary to investigate the physical components according to sampling site for the MBT to introduce for combustible municipal solid waste pre-treatment, but it needs the chemical composition from landfill site to design the incinerator. The physical composition showed that the combustible and the noncombustible occupied 87.4% and 12.6% respectively. In case of three component analysis, the moisture, the combustible, and the ash were 27.6, 60.5, 11.9% respectively. The chemical composition through the element analysis were C (50.1%), H (6%), O (39.5%), N (1.9%), S (0.5%), and Cl (1.3%).

본 연구에서는 현재 사용 중인 2곳(H, Y 매립지)의 소규모 매립장에 대한 매립지 특성 자료수집과 현장측정을 통한 LFG 배출량 산정을 수행하였으며, 이를 이용하여 이들 매립지에 적합한 2006 IPCC FOD 방법 적용 시 입력변수로 사용되는 메탄발생속 도상수(k)를 산출하여 보았다. 또한 이 결과를 default 값을 적용한 2006 IPCC GL의 FOD 방법에 의한 메탄 배출량 산정결과와 비교함으로써 특정매립지에 대한 동일한 k값 적용의 타당성을 평가해 보았다. 매립지의 폐기물 조성 data를 이용한 DOC 산정 결과, 매립되어지는 폐기물의 물리적 조성 차이로 인하여 H 매립지(1997∼2011)는 13.16 %∼23.79 %(16.52 ± 3.84 %)로 나타났으며, Y매립지(1994∼2011)는 7.24 %∼34.67 %(14.56 ± 7.30 %)의 값을 보여 IPCC 가이드라인에서 제시한 Bulk waste 타입의 기본값인 18.0 %와 비교할 때 H 매립지보다 Y 매립지가 큰 차이를 보였다. 2006 IPCC GL에 제시된 FOD방법의 메탄 배출량 산정식을 이용한 k값 산정 결과, H 매립지의 산정된 평균 k값은 0.0413 yr<SUP>-1</SUP>, Y 매립지의 산정된 평균 k값은 0.0117 yr<SUP>-1</SUP>로 나타나 IPCC 가이드라인에 제시된 기본값인 0.09 yr-1에 비하여 상대적으로 낮은 값을 보였다. 따라서 2006 IPCC 가이드라인의 defaults value(k=0.09) 값에 의한 온실가스 배출량 산정결과는 현장측정을 통해 산정된 k값에 의한 추정값에 비하여 과대평가될 수 있어 매립지에서 발생하는 정확한 온실가스 배출량 예측을 위해서는 각각의 매립지별 현장측정을 통한 고유의 k값 결정을 통한 산정이 진행되어야 할 것으로 판단된다. In this study, greenhouse gas emission for small scale landfill (H and Y landfill) was investigated to deduce special the methane generation rate constant(k). To achieve the purpose, the data of physical composition was collected and amount of LFG emission was calculated by using FOD method suggested in 2006 IPCC GL. Also, amount of LFG emission was directly measured in the active landfill sites. By comparing the results, the methane generation rate constant(k), which was used as input variable in FOD method suggested in 2006 IPCC GL, was deduced. From the results on the physical composition, it was shown that the ranges of DOC per year in H (1997∼2011) and Y (1994∼2011) landfill sites were 13.16 %∼23.79 % (16.52 ± 3.84 %) and 7.24 %∼34.67 % (14.56 ± 7.30 %), respectively. The DOC results showed the differences with the suggested values (= 18 %) in 2006 IPCC GL. The average values of methane generation rate constant(k) from each landfill site were 0.0413 yr<SUP>-1</SUP> and 0.0117 yr<SUP>-1</SUP>. The results of methane generation rate constant(k) was shown big difference with 2006 IPCC GL defualt value (k = 0.09). It was confirmed that calculation results of greenhouse gas emission using default value in 2006 IPCC GL show excessive output.

These days, animal infectious disease such as AI(Avian Influenza) and FMD(Foot-and-Mouth Disease) breaks out, and increase the number of its occurrence. Offered in "An animal disease prevention" of Ministry of Agriculture and Forestry that to do killed caused livestock order to prevent diffuse pollution of the epidemic when an animal disease has happened. Accordingly, in Ministry of Agriculture and Forestry set up the "Emergency Action Guide", it suggests the emergency cation, disposal method(stamping out, incineration, burying method), disposal method of livestock excretions in the area of origin. Also, the department of the environment makes the livestock burial regional environmental research guidelines, it order to investigate the surround environment, water quality in monitoring well, environment management and so on. In korea, this was the first time confirmed that the foot-and-mouth disease occurred in 1934. The leachate buried underground of livestock is organic waste water and it has been arranged nutrient salts such as nitrogen, phosphorus. So, there is a possibility that can lead to a variety of environmental problems when it can result in river pollution, ground water pollution and soil pollution. Look at domestic and foreign research trend leachate behavior such as contamination analysis through physicochemical properties or physicochemical analysis of the leachate components have been identified and carried out. Because of the leak of the leachate, there is a possibility about the around soil pollution. Thus, we studied that investigation of soil texture around livestock burial site in chung-buk north area of korea. From the result, surface soil was loam and subsoil was clay loam soil in 35% of survey site. In the future, this result will be a important basis data for correlation of leachate leak and consequential soil texture.
