Landfills are substantial anthropogenic sources of greenhouse gases such as methane (CH₄), carbon dioxide (CO₂), and non-methane volatile organic compounds (NMVOCs). This study reports a simple and efficient method for determining the environmental loads of landfill gases (LFG) emitted from the Nam Binh Duong landfill, Vietnam, by applying the LandGEM and the IPCC first-order decay models (FOD model). The environmental LFGs loads were quantified based on both the relevant parameters of the generation potential (L₀) of 81 m³/Mg and the generation rate (k) of 0.355 year⁻¹ of methane (CH₄) as well as the average measurement value of CH₄ (57% by volume of the LFGs) obtained throughout the on-site measurements of the investigated landfill (Scenario 1). Then, the quantified emission results of the LFGs were compared to those of the Clean Air Act (CAA) default mode of the model (Scenario 2). During the period from 2004 to 2144, the projected landfill methane emissions add up to 116,377 t of CH₄ with an average of 825 t of CH₄/year. The paired t test conducted to compare the gas emissions obtained from both scenarios demonstrated that the on-site parameters significantly affect the yield of the LFGs. The estimated total LFG, methane, CO_2, and NMVOCs recovery potential can serve as supporting data for policy making on obtaining renewable energy from landfills and minimizing the environmental issues caused by LFGs emissions.

垃圾填埋场是大量的人为温室气体，例如甲烷（CH ₄），二氧化碳（CO ₂）和非甲烷挥发性有机化合物（NMVOCs）。这项研究报告了一种简单有效的方法，可以通过应用LandGEM和IPCC一阶衰减模型（FOD模型）来确定越南Nam Binh Duong垃圾填埋场排放的垃圾填埋气体（LFG）的环境负荷。基于81 m ³ / Mg的产生电势（L ₀）和甲烷（CH ₄）的发电速度（k）为0.355年^-1的相关参数对LFG的环境负荷进行了量化CH值在对被调查的垃圾填埋场进行现场测量的整个过程中获得了_4种（按体积计为LFG的57％）（方案1）。然后，将LFG的量化排放结果与模型的《清洁空气法》（CAA）默认模式的排放结果进行比较（方案2）。在2004年至2144年期间，预计垃圾填埋场甲烷排放量总计为116377吨CH ₄，平均每年为825 t CH ₄。为比较从两种情况获得的气体排放而进行的配对t检验表明，现场参数显着影响了LFG的产量。估计的总LFG，甲烷，CO ₂ NMVOC的回收潜力可以作为决策数据的支持数据，这些政策是从垃圾填埋场获取可再生能源，并最大程度地减少由LFG排放引起的环境问题。
