本研究は、竹ベース加工製品の製造過程におけるバイオマス由来炭素の保持効率を定量化する新指標「炭素移行効率（CTE）」を提案した。中国の竹スカンバー工場の実データに基づき、cradle-to-gateの炭素フットプリントと併せて評価し、初期バイオジェニック炭素の65–78%が最終製品に保持されることを示した。炭素損失はユニット分離と二次加工で70%以上を占め、材料損失パラメータがCTEに強く影響することを明らかにした。
English
This study proposes carbon transfer efficiency (CTE) as a complementary indicator to LCA for quantifying biogenic carbon retention in bamboo-based engineered products. Using plant-scale data from a Chinese bamboo scrimber factory, it finds 65–78% of initial biogenic carbon is retained in final products, with unit separation and secondary machining responsible for over 70% of carbon loss. CTE and GHG emissions capture different environmental dimensions, offering a more comprehensive framework for low-carbon manufacturing.

📄 Abstract（原文）
Bamboo-based engineered products have attracted increasing attention because of their renewable origin and long-term carbon storage potential. However, conventional life cycle assessment (LCA) mainly evaluates greenhouse gas emissions and cannot quantify how efficiently biomass-derived carbon is retained during manufacturing. Therefore, this study proposes carbon transfer efficiency (CTE) as a complementary indicator for assessing retained biogenic carbon in bamboo-based engineered products. Based on plant-scale manufacturing data from a representative bamboo scrimber factory in China, CTE was quantified together with the cradle-to-gate carbon footprint. Carbon loss distribution among manufacturing stages and sensitivity to key process parameters were further analyzed. Results showed that 65–78% of the initial biogenic carbon was retained in the final product. Unit separation and secondary machining accounted for more than 70% of total carbon loss, whereas adhesive application and hot pressing dominated greenhouse gas emissions but caused little direct carbon loss. Material-loss-related parameters exhibited substantially greater influence on CTE than energy-related parameters. These findings demonstrate that carbon retention efficiency and greenhouse gas emissions characterize different dimensions of environmental performance. Integrating CTE with LCA provides a more comprehensive framework for evaluating carbon storage and low-carbon manufacturing of bamboo-based engineered products.
