Measurements of landfill methane emission were performed at nine solid waste disposal sites in Thailand, including five managed sanitary landfills (four deep and one shallow landfills) and four unmanaged landfills (three deep and one shallow dumpsites). It was found that methane emissions during the rainy season were about five to six times higher than those during the winter and summer seasons in the case of managed landfills and two to five times higher in the case of unmanaged landfills. Methane emission estimate using the Intergovernmental Panel on Climate Change (IPCC) Waste Model was compared with the actual field measurement from the studied disposal sites with methane correction factors and methane oxidation factors that were obtained by error function analysis with default values of half-life parameters. The methane emissions from the first-order decay model from the IPCC Waste Model yielded fair results compared to field measurements. The best fitting values of methane correction factor were 0.65, 0.20, 0.15, and 0.1 for deep landfills, shallow landfills, deep dumpsites, and shallow dumpsites, respectively. Using these key parameters in the case of Thailand, it was estimated that 89.22 Gg of methane were released from solid waste disposal sites into the atmosphere in 2006.
在泰国的 9 个固体废物处置场进行了填埋场甲烷排放测量，其中包括 5 个管理卫生填埋场（4 个深填埋场和 1 个浅填埋场）和 4 个无管理填埋场（3 个深填埋场和 1 个浅垃圾场）。结果发现，管理填埋场在雨季的甲烷排放量约为冬季和夏季的五到六倍，而无管理填埋场的甲烷排放量则为两到五倍。使用政府间气候变化专门委员会（IPCC）废物模型估算的甲烷排放量与从研究处置场获得的实际现场测量结果进行了比较，其中使用误差函数分析得到了甲烷校正因子和甲烷氧化因子，这些因子的半衰期参数采用默认值。与现场测量结果相比，IPCC 废物模型中一阶衰减模型的甲烷排放量产生了较好的结果。深填埋场、浅填埋场、深垃圾场和浅垃圾场的甲烷校正因子的最佳拟合值分别为 0.65、0.20、0.15 和 0.1。在泰国的情况下，使用这些关键参数估计 2006 年有 89.22 Gg 的甲烷从固体废物处置场释放到大气中。
