本稿は、食品ロス・廃棄物（FLW）の削減が十分に進んでいない現状を指摘し、予防だけではなくリサイクル（堆肥化、嫌気性消化、飼料化）による排出削減の重要性を主張する。成熟したリサイクル経路は1トンあたり約900-1150 kg CO2eの削減が可能であり、埋立回避とリサイクル最適化を重視する枠組みを提案する。
English
This perspective argues that food loss and waste (FLW) levels have not declined meaningfully under the prevention paradigm. It advocates for recycling pathways like composting, anaerobic digestion, and animal feed, which can reduce emissions by 900–1150 kg CO2e per metric ton. A best-use framework for allocating FLW streams is introduced.

日本のGX文脈において
日本では食品廃棄物のリサイクル法（食品リサイクル法）やバイオガス発電の普及が進むが、埋立率はまだ高い。本稿は、埋立回避による即効性のある排出削減策を示しており、日本の自治体・事業者の廃棄物対策に示唆を与える。
In the global GX context
Globally, food waste recycling is gaining traction as a climate solution. This paper synthesizes evidence that mature recycling pathways offer immediate, scalable mitigation, supporting policies like the EU's Circular Economy Action Plan and UNEP's Food Waste Index.

📄 Abstract（原文）
Food loss and waste (FLW) is a defining inefficiency of the global food system, with far-reaching implications for food security, climate change, and resource and environmental sustainability. In this Perspective, we review evidence from global assessments to indicate that FLW levels have not declined meaningfully despite a decade of focus on Sustainable Development Goal 12.3 to halve per capita FLW by 2030. Experience from leading countries suggests that structural constraints limit achievable reductions through prevention alone. As near-term climate mitigation windows narrow, strategies beyond prevention are required. We argue that eliminating landfill and open-dump disposal of food waste represents an immediate and scalable mitigation opportunity, because systems-based evidence demonstrates that mature recycling pathways – including composting, anaerobic digestion, and repurposing food waste as animal feed – can deliver emissions reductions of approximately 900–1150 kg CO 2 e per metric ton of food waste while recovering nutrients and sparing energy and land resources. We introduce a best-use framework that allocates FLW streams across recycling options based on emission mitigation potential, resource recovery, and implementation feasibility. Reframing food waste management from a prevention-dominated paradigm toward a landfill-avoidance and recycling-optimization paradigm provides a pragmatic path for near-term emissions abatement while advancing long-term sustainability objectives.
