食品廃棄物の4つの処理戦略（飼料化、埋立、好気性コンポスト、嫌気性消化と消化液固形分のコンポスト化）を炭素収支分析で比較したレビュー。嫌気性消化と固形分コンポストの統合が最も高い資源回収と炭素変換を実現し、腐植物質に富む安定した有機肥料が得られることを示す。易分解性・腐植性・難分解性炭素画分が農学的特性を左右する点を強調する。

This review compares four food waste management strategies—animal feed, landfill disposal, aerobic composting, and anaerobic digestion with digestate application or solid-fraction composting—using carbon balance analysis. Integrating anaerobic digestion with solid-fraction composting achieves the highest resource recovery and carbon conversion, yielding stable humic-enriched organic fertilizer. Labile, humic, and resistant carbon fractions are shown to govern agronomic properties of the products.

📄 Abstract（原文）
This study presents an assessment of food waste management strategies with a focus on resource recovery and carbon transformation. Four approaches were considered: direct use as animal feed, uncontrolled disposal at landfills, aerobic composting, and anaerobic digestion with either direct application of digestate or subsequent composting of its solid fraction. The effectiveness of each strategy was evaluated using carbon balance analysis combined with literature data on carbon forms in biodegradation products. The results indicate that the highest degree of food waste utilization and carbon conversion is achieved through the integration of anaerobic digestion with composting of the solid fraction of digestate, resulting in a stable organic fertilizer enriched with humic substances. Direct application of digestate ensures rapid availability of nutrients, particularly ammonium nitrogen; however, it is associated with increased environmental risks. Aerobic composting improves product stability, sanitary safety, and soil fertility, while partially reducing greenhouse gas emissions compared to uncontrolled disposal. The roles of labile, humic, and resistant carbon fractions in determining the agronomic properties of biodegradation products are highlighted. The results support the integrated implementation of food waste management strategies to optimize energy recovery, nutrient recycling, and environmental protection.
