本レビューは、中国における農業有機固形廃棄物（AOSW）の堆肥化と嫌気性消化（AD）による温室効果ガス（GHG）排出量を評価した。堆肥化からの生物起源GHGは30–740 kg CO2-eq/t DM、ADからのメタン漏洩は196.5–982.4 kg CO2-eq/t DMと報告。プロセス調整により13.9–55.8%、外因性添加により6.0–97.3%の削減が可能。低炭素資源循環への示唆を提供。

This review evaluates greenhouse gas (GHG) emissions from composting and anaerobic digestion (AD) of agricultural organic solid wastes (AOSW) in China. Composting biogenic GHG ranges 30–740 kg CO2-eq/t DM, while AD methane leakage contributes 196.5–982.4 kg CO2-eq/t DM. Process regulation can reduce emissions by 13.9–55.8% and exogenous addition by 6.0–97.3%. The paper supports low-carbon resource recycling strategies.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
中国の農業廃棄物処理に焦点を当てているが、日本でもバイオマス活用や有機廃棄物のメタン発酵が進んでおり、GHG排出原単位の比較や削減策の参考になる。日本の農林水産省の「みどりの食料システム戦略」にも関連。
In the global GX context
While focused on China's agricultural waste, the emission factors and reduction strategies are globally relevant for organic waste management. It provides benchmarks for composting and AD systems, useful for lifecycle assessment and climate reporting under frameworks like ISSB/GHG Protocol.
👥 読者別の含意
🔬研究者:Provides a comprehensive review of GHG emission factors from agricultural waste treatment, useful for LCA and emission inventory modeling.
🏢実務担当者:Offers quantitative reduction potentials from process regulation and additives, applicable to waste treatment facility optimization.
🏛政策担当者:Supports development of national GHG reduction strategies for agricultural waste sector.
📄 Abstract（原文）
Agricultural organic solid wastes (AOSW) are often accompanied by agricultural production, with large quantities, leading to resource waste and environmental impacts. Composting and anaerobic digestion (AD) are mainstream and recommended methods of AOSW disposal in China. This research conducts a review of the greenhouse gas (GHG) emissions of AOSW composting and AD methods, with consideration of advancements, challenges, limitations, and future directions. Composting’s biogenic GHG contributes 30–740 kg CO2-eq·t−1 DM, with feedstock and systems as main factors. AD’s biogenic GHG comes from 0–10% methane leakage (196.5–982.4 kg CO2-eq·t−1 DM) and digestate composting (276.6–1002.3 kg CO2-eq·t−1 DM). Non-biological GHG for both is 11.3–561.8 kg CO2-eq·t−1 DM. Process regulation cuts GHG by 13.9–55.8%, exogenous addition by 6.0–97.3%. This paper highlights and discusses AOSW biological treatment’s GHG emission and reduction strategy, supporting low-carbon resource recycling.
