本研究は、深圳市を対象に、食品廃棄物の分別・資源化が廃棄物処理システム全体に与える環境・経済的影響を統合的ライフサイクル分析で評価した。処理技術間の相互依存を考慮することで、従来の単一プロセス評価では見えなかった相乗効果を実証し、地球温暖化係数を最大116.6kgCO2eq/t、ライフサイクルコストを44.3CNY/t削減できることを示した。排出削減とエネルギー回収の最大化がシステム全体のパフォーマンス向上に重要であり、統合的ガバナンスと部門横断的な調整の必要性を強調している。
English
This study evaluates the environmental and economic impacts of separate food waste utilization in Shenzhen using an integrated life-cycle analysis framework. By accounting for interdependencies among treatment technologies, it reveals synergistic effects that reduce global warming potential by up to 116.6 kg CO2 eq/t and life-cycle cost by 44.3 CNY/t. The findings emphasize minimizing direct emissions and maximizing energy recovery, and highlight the need for integrated governance and cross-departmental coordination in waste management.

日本のGX文脈において
日本では食品リサイクル法や循環型社会形成推進基本計画に基づき食品廃棄物の削減・資源化が進められており、本研究成果は自治体の廃棄物処理計画や統合的評価に示唆を与える。特に、処理技術間の相互依存を考慮したシステム全体の最適化は、日本の市町村における廃棄物処理施設の計画や広域化に応用可能である。
In the global GX context
This research contributes to global circular economy scholarship by demonstrating that integrated system design can overcome trade-offs between environmental and economic objectives in waste management. The findings are relevant for cities worldwide implementing separate collection and valorization of organic waste, and support policy frameworks such as the EU's Circular Economy Action Plan and SDG 12.3 on food waste reduction.

📄 Abstract（原文）
Traditional waste management systems often necessitate trade-offs between environmental and economic objectives when designing municipal solid waste (MSW) treatment infrastructure. While effective food waste (FW) utilization is critical for advancing circular economy (CE) principles, single-process assessments typically reveal conflicts between environmental benefits and economic constraints. Taking Shenzhen as a case study, this research challenges this conventional perspective by developing an integrated life-cycle analysis framework to evaluate system-wide impacts of separate FW utilization. The analysis demonstrates that FW segregation and valorization generate synergistic effects when accounting for interdependencies among treatment technologies. The overall energy recovery of the MSW treatment system was enhanced, maximumly reducing global warming potential by 116.6 kg CO 2 eq/t and LCC by 44.3 CNY/t. Correlation analysis between environmental and economic performance identified two fundamental strategies to improve system-wide performance as minimizing direct emissions and maximizing energy recovery. Sensitivity results further emphasize the inextricable linkage between source reduction and terminal resource utilization, underscoring the necessity of integrated system design. Municipal authorities should prioritize integrated governance and cross-departmental coordination to unify environmental, economic, and social objectives in waste management, while robust economic incentives, enhanced market confidence and active public participation are essential to accelerate CE transitions.
