本研究は、欧州で広く利用可能な農産加工副産物（ブドウ、オリーブ、トマト搾りかす、ビール粕）の炭素フットプリント（CFP）をISO 14067に基づき評価した。乾燥副産物1kgあたり0.21-0.31 kg CO2eと推定され、従来飼料の部分代替により羊・山羊飼料のCFPを平均23%削減、全体で5.15 Mt CO2eの緩和ポテンシャルが示された。ただし、結果はモデルベースであり、乾燥条件や輸送の除外等の仮定に依存する。
English
This study assessed the carbon footprint (CFP) of European agro-industrial by-products (grape, olive, tomato pomaces, spent beer grains) using ISO 14067. CFP ranged from 0.21-0.31 kg CO2e/kg dried product. Replacing conventional feed in sheep and goat diets reduced diet CFP by 23% on average, with a mitigation potential of 5.15 Mt CO2e. Results are model-based and depend on assumptions about drying, transport, and substitution feasibility.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本でも、食品廃棄物削減と畜産由来GHG排出削減の観点から、国内の農産加工副産物（酒粕、おから等）の飼料利用拡大が検討されている。本論文のLCA手法やCFP算定結果は、日本におけるデータ整備や政策立案の参考になる可能性がある。
In the global GX context
This study provides a quantitative LCA-based assessment of using agro-industrial by-products to reduce feed carbon footprint. It aligns with global efforts to circularize food systems and reduce scope 3 emissions in agriculture. The methodology (ISO 14067) and mitigation potential estimates offer a template for similar assessments in other regions, though assumptions limit direct generalizability.
👥 読者別の含意
🔬研究者:Provides a detailed LCA methodology and CFP values for common by-products, useful for researchers modeling agricultural supply chain emissions.
🏢実務担当者:Livestock and feed companies can use these CFP estimates to explore by-product substitution opportunities and quantify emissions reductions.
🏛政策担当者:Offers evidence for policies promoting circular bioeconomy and low-carbon feed regulations.
📄 Abstract（原文）
In this study, we aimed to assess the availability and environmental impact of a selection of widespread agro-industrial by-products in Europe and their potential to reduce the environmental impact of small ruminant diets by replacing conventional feed ingredients. Grape, olive, and tomato pomaces and spent grains of beer were considered. The carbon footprint of products (CFP) was used to quantify the environmental impact of agro-industrial by-products, according to the ISO 14067:2018 standard. The system boundary was defined as gate-to-gate, and 1 kg of dried by-product was chosen as the functional unit (FU). The system included the relevant stages of agro-industrial by-product production, from the process of drying agro-industrial by-products to the treatments carried out in the feed industry (e.g., milling, mixing, and pelleting). The CFPs of grape, olive, and tomato pomaces and spent beer grains were 0.26, 0.22, 0.31, and 0.21 kg CO2 equivalents (CO2e)/FU, respectively. Under the assumptions adopted in this scenario-based assessment, reusing grape, olive, tomato, and brewery industry by-products as partial replacements for conventional feed ingredients in sheep and goat diets reduced diet CFP by an average of 23%, with an estimated mitigation potential of 5.15 Mt CO2e. These values should be interpreted as model-based estimates rather than as directly generalizable mitigation outcomes, because they depend on the selected system boundary, drying assumptions, emission factors, transport exclusion, and the practical feasibility of the dietary substitutions considered. Overall, the results suggest that the recovery of selected agro-industrial by-products may contribute to reducing the environmental impact of conventional feed ingredients when appropriate preservation, logistics, and diet formulation conditions are met.
