한국과 일본은 폐기물 처리방법, 날씨, 지리적으로 다르다. 그러한 차이에 의해 두 나라의 매립 관리 방법에 대해 동일한 조건하에서 비교하기는 어렵다. 그러나, 어떠한 조건에서든 두 나라의 매립지 침출수 관리는 중요하며, 침출수 처리 시설의 규모 산정과 물수지 시뮬레이션을 통한 침출수 조절 시설의 산정은 더욱 중요하다. Korea and Japan have different waste management methods, weather and geography. Such differences make it difficult to compare the landfill management methods of both countries under identical conditions. Under any conditions, however, leachate management at a landfill in both countries is important and setting the scale of leachate treatment facility and that of leachate adjustment facility through water balance simulations is much more important.

The objective of this study was to determine the CH4 oxidation factor (%) and the CH4 oxidation rate (g m−2 d−1) in landfill cover soil. To quantify in-situ rates of CH4 oxidation, CH4 and CO2 fluxes were measured on a landfill site using the static chamber technique. The CH4 oxidation factor obtained in this study through the mass balance method ranged between 41% and 61%, which is much higher than the Intergovernmental Panel on Climate Change (IPCC) default value of 10%. The higher CH4 oxidation factor derived in this study can be explained by the CH4 bottom flux in addition to the soil texture. The CH4 oxidation factors were observed to increase with decreases in CH4 bottom flux. Therefore, when CH4 bottom fluxes are high in a landfill, using a gas collection system can enhance CH4 oxidation factor. The CH4 oxidation rates were estimated to range from 16.6 g m−2 d−1 to 20.8 g m−2 d−1. In addition, this study was conducted to evaluate the effects of vegetation on the CH4 oxidation factor. The results showed that the CH4 oxidation factors for bare soil, vegetated soil, and soil adjacent to a gas well were 57%, 70%, and 44%, respectively. The results indicate that vegetation on landfill covers can increase the CH4 oxidation factor because of increasing soil porosity.
