本研究はブラジル・マリンガの埋立地からのメタン発生量を3つのモデルで推定し、エネルギー回収ポテンシャルと健康便益を評価。メタン濃度は51-57%で、最大1.30×104トンのCH4発生を試算。バイオガス回収により、気候変動対策と大気汚染低減の共便益が得られることを示した。
English
This study estimates methane generation from a Brazilian landfill using three models, finding concentrations of 51-57% CH4 and peak production over 25-26 years. Controlled biogas recovery can reduce methane emissions and improve air quality, offering co-benefits for climate and public health, particularly in developing countries with inadequate waste management.

日本のGX文脈において
日本の廃棄物政策では、メタン回収型埋立施設やバイオガス発電が普及しつつある。本論文の実証データや健康便益の定量化は、日本の自治体や事業者が埋立地バイオガス事業の価値を説明する際に参考になる。
In the global GX context
This paper provides empirical data on landfill biogas recovery from a developing country context, showing how waste-to-energy can support both climate mitigation (SDG 13) and public health (SDG 3). For global audiences, it reinforces the importance of integrating landfill gas capture into waste management policies, especially where open dumping is still common.

📄 Abstract（原文）
Biogas from municipal solid waste is a promising pathway for renewable energy production while mitigating environmental pollution and public health risks. In this study, biogas emissions from a sanitary landfill in Maringá, southern Brazil, were evaluated using three models (IPCC, LandGEM, and CETESB tool) to estimate methane generation and energy recovery potential. Experimental analysis revealed methane concentrations from 51.10 ± 8.89% to 57.06 ± 1.19% across collection drains, indicating favorable conditions for energy utilization. Methane generation was estimated under different scenarios, reaching up to 1.30 × 104 tonnes of CH4, with peak production projected over 25–26 years depending on the model. Beyond energetic relevance, controlled biogas recovery can substantially reduce methane emissions, a key precursor of tropospheric ozone, and limit hazardous trace gas release, improving air quality and reducing population exposure to harmful pollutants. These findings are particularly relevant in developing countries, where insufficient waste management infrastructure leads to uncontrolled emissions, posing elevated environmental and health risks. This study supports integrating landfill biogas recovery into waste management and climate strategies, contributing to Sustainable Development Goals related to clean energy (SDG 7), climate action (SDG 13), and health (SDG 3), demonstrating it as a scalable solution for sustainable urban development.
