本研究は、南アジアの都市廃棄物問題に対処するため、焼却・嫌気性消化・ガス化・熱分解を含む廃棄物発電（WTE）技術のハイブリッドシステムを評価。LCAと技術経済分析を統合し、分散型ハイブリッドシステムが landfill依存を60-80%削減し、炭素排出を30-50%削減することを示した。分散型システムの投資回収期間は5-8年と集中型より短い。
English
This study evaluates hybrid waste-to-energy (WTE) systems combining incineration, anaerobic digestion, gasification, and pyrolysis for South Asian cities. Integrating LCA and techno-economic analysis, it finds that decentralized hybrid designs reduce landfill dependence by 60-80% and carbon emissions by 30-50%, with shorter payback periods of 5-8 years compared to centralized systems.

📄 Abstract（原文）
Rapid urbanization in South Asia has significantly increased municipal solid waste (MSW) generation, intensifying infrastructure and environmental health challenges. Open dumping remains a common waste management practice, but it contributes to climate change through methane emissions, while large-scale empirical research on sustainable solutions for vulnerable megacities remains limited. This study assesses the technical, environmental, and economic feasibility of waste-to-energy (WTE) systems to enhance urban climate resilience and circular resource use. The analytical framework integrates life cycle assessment (LCA) and techno-economic analysis of incineration, anaerobic digestion, gasification, and pyrolysis. Performance indices for selected South Asian cities were evaluated using multi-criteria decision-making models. MSW generation was estimated at 0.5-0.8 kg/capita/day, with organic fractions of around 50-65%. Hybrid systems achieved the highest performance scores, reducing landfill dependence by 60-80% and carbon emissions by 30-50%. Decentralized designs showed shorter payback periods of 5-8 years compared with 8-12 years for centralized systems. The paper concludes that decentralized hybrid WTE technologies offer a transformative and scalable pathway to sustainable urban growth and climate adaptation in South Asia.
