日本語

イラク・クルディスタン地域のエルビル市埋立地を対象に、LandGEMとIPCC Tier 1モデルを初めて同時適用し、メタン排出量とエネルギー回収ポテンシャルを比較した。2032年のピーク排出量はLandGEMで8.9×10⁷ m³/年、IPCCで1.8×10⁸ m³/年と試算され、エネルギー回収は206～416 GWh/年と推定。モデル間の差は一次減衰速度の扱いに起因し、ガス収集設備の設計に影響する。

English

This study applies LandGEM and IPCC Tier 1 models to Erbil City landfill, Iraq, comparing methane emissions and energy recovery potential. Peak CH4 emissions in 2032 are projected at 8.9e7 m3/yr (LandGEM) and 1.8e8 m3/yr (IPCC), yielding 206-416 GWh/yr energy. The divergence stems from IPCC's omission of first-order decay, affecting gas collection system sizing. Results support active gas collection infrastructure for renewable energy.

📄 Abstract（原文）

<p>Landfill methane (CH₄) emissions represent a significant greenhouse gas (GHG) source globally. This study presents the first simultaneous application and comparison of the LandGEM v3.02 and IPCC Tier 1 models for the Erbil City landfill, Kurdistan Region, Iraq, covering waste acceptance from 2001 to 2031. LandGEM parameters (k = 0.05 year⁻¹; L₀ = 170 m³/Mg) and IPCC parameters (DOC = 0.18; DOC<sub>f </sub>= 0.70; MCF = 0.8; F = 0.5) were applied, with energy recovery estimated at 75% CH₄ collection efficiency and 33% electrical conversion efficiency. Peak CH₄ emissions in 2032 are projected at 8.9 × 10⁷ m³/year (LandGEM) and 1.8 × 10⁸ m³/year (IPCC), yielding energy potentials of 206 and 416 GWh/year, respectively. The divergence arises because IPCC Tier 1 omits first-order decay kinetics, producing an upper-bound estimate, directly affecting landfill gas collection system sizing and infrastructure decisions. Gross revenue potential ranges from $24–58 million/year, or $10–16 million/year under conservative 40% collection efficiency. All results are model-based projections without field validation. Findings support prioritizing active gas collection infrastructure to convert Erbil’s landfill into a renewable energy asset and provide a quantitative basis for regional waste management policy. </p>
