中国の下水処理産業が2035年までに炭素中立を達成するための費用対効果の高い経路をレビュー。省エネ曝気、スマート制御、薬品最適化、汚泥管理などの短期的優先事項と、嫌気性消化、再生水利用、再生可能エネルギー統合などの長期的対策を評価。大規模都市プラントは資源回収センターへ、中小都市は段階的改修、農村は低エネルギー分散処理、工業団地は源管理と水エネルギー循環を推奨。ライフサイクルコスト評価、限界削減分析、モニタリング、料金改革、グリーンファイナンス、統合ガバナンスの重要性を指摘。
English
This review evaluates cost-effective pathways for carbon-neutral wastewater treatment in China by 2035, integrating carbon reduction, resource reuse, and regional planning. It identifies near-term priorities like energy-efficient aeration, intelligent control, and sludge management, and long-term measures like anaerobic digestion, biogas, and renewable integration. A differentiated approach is proposed: large urban plants become resource-recovery centers, small cities adopt gradual retrofits, rural areas use low-energy decentralized systems, and industrial parks focus on source control and water-energy recycling. Life-cycle cost assessment, marginal abatement analysis, monitoring, tariff reform, green finance, and integrated governance are deemed essential.

日本のGX文脈において
日本の下水処理分野では、カーボンニュートラルに向けた省エネ・創エネ技術の導入が進むが、中国の地域差を考慮した差別化アプローチは、日本の地域特性に応じた戦略立案に示唆を与える。また、SSBJ開示や投資家対応において、下水処理の排出削減コスト分析は有用。
In the global GX context
This paper contributes to global GX scholarship by providing a cost-optimized framework for decarbonizing wastewater treatment, a sector often overlooked in climate disclosure. It offers insights for aligning with ISSB/CSRD requirements on Scope 1 and 2 emissions, and highlights the role of green finance and integrated governance in achieving sectoral carbon neutrality.

📄 Abstract（原文）
The wastewater treatment industry in China is under pressure to balance tighter pollution control with the national carbon-neutrality objectives. This review evaluates cost-effective solutions to achieve carbon-neutral wastewater treatment in China by 2035, focusing on the integration of carbon reduction, resource reuse, and regional infrastructure planning. Direct emissions of methane and nitrous oxide in the carbon profile of wastewater treatment plants result directly from biological and sludge processes and indirectly from electricity, chemicals, construction, and sludge disposal. Due to the large-scale variation in plants in China, the quality of influent, climate, grid carbon intensity, water shortage, and financial capability, it is unlikely that the uniform application of technology will be cost-effective. The review has found the following near-term priorities to be highly economically viable: energy-efficient aeration, intelligent process control, chemical optimization, and improved sludge management. More extreme decarbonization involves anaerobic digestion, co-digestion, biogas, heat recovery, nutrient recovery, reuse of reclaimed water, and integration of renewable electricity. The proposed alternative is a differentiated approach: large urban plants are to be transformed into resource-recovery centres; small and medium cities are to implement gradual retrofits and regional sludge management; the rural focus is to be on strong, low-energy decentralized treatment; and industrial parks are to be encouraged to establish source control and water-energy recycling. The life-cycle cost assessment, marginal abatement analysis, plausible monitoring, tariff reform, green finance, and integrated water-energy-waste governance will be essential to achieving carbon neutrality across sectors by 2035.
