中国の「双炭」と「ゼロウェイスト都市」戦略のもと、都市ごみ焼却（MSWI）が都市の炭素フローハブへ転換しつつある。本レビューは、炭素会計、全チェーン排出削減技術、政策枠組みを統合的に分析。従来の静的会計は排出量を最大40%過大評価するため、14CO2同位体とデジタルツインを統合した動的MRVシステムへの移行が必要と指摘。技術的には「発生源-プロセス-シンク」の相乗効果が鍵で、灰の鉱物化と建材代替が有望。ライフサイクル経済分析で「廃棄物で廃棄物を処理」アプローチの商業的実現性を確認。政策面では排出削減をコンプライアンス免除に組み込む基準改定と炭素市場との統合を提言。
English
Under China's 'dual carbon' and 'zero-waste city' strategies, municipal solid waste incineration (MSWI) is becoming a key urban carbon hub. This review integrates carbon accounting, full-chain mitigation technologies, and policy frameworks. Static accounting can overestimate emissions by up to 40%, necessitating dynamic MRV with 14CO2 isotopes and digital twins. A 'source-process-sink' synergy is key, with ash mineralization and building material substitution promising. Life-cycle economics confirm the commercial viability of 'treating waste with waste.' Policy revisions should integrate mitigation into compliance exemptions and deepen carbon market links to move MSWI toward negative-carbon energy.

📄 Abstract（原文）
Driven by the "dual carbon" and "zero-waste city" strategies in China, municipal solid waste incineration (MSWI) is transitioning from a treatment terminal into a critical urban carbon flow hub. This study reviews the carbon accounting systems, full-chain carbon emission reduction technologies, and macro-environmental policy frameworks for MSWI decarbonization. Traditional static accounting can overestimate emissions by up to 40%, necessitating a shift toward dynamic monitoring, reporting, and verification systems that integrate 14 CO 2 isotopes and digital twins.Technologically, the carbon emission reduction paradigm has shifted to a "sourceprocess-sink" synergy that enhances targeted fossil carbon sorting at the source, unleashes the thermal potential of MSWI via intelligent combustion control, and strategically focuses on the accelerated mineralization and building material substitution of ash at the sink. Life-cycle economic analyses confirmed that the "treating waste with waste" approach is commercially viable. Ultimately, to realize the full carbon emission reduction potential of MSWI, the underlying pollution control standards must be revised to incorporate mitigation benefits into compliance exemption systems. Moreover, deep integration with carbon markets is required to drive the evolution of MSWI toward a regional negative-carbon energy paradigm.
