本研究は、竹ベース活性炭の3つの製造経路（粒状、粉末、押出成形）について、実生産データに基づくゆりかごからゲートまでのカーボンフットプリントを評価。内部熱回収により排出量を73.8〜81.7%削減し、石炭ベース品と比べ約95%の排出削減を達成。LCAモデルと配分比率スキャニング手法を検証した。
English
This study evaluates the cradle-to-gate carbon footprint of three bamboo-based activated carbon pathways (granular, powdered, extruded) using primary data from a 10,000 t/year production line. Internal heat recovery reduces emissions by 73.8-81.7%, and bamboo-based products achieve ~95% emission reduction compared to coal-based alternatives. An LCA model with allocation ratio scanning is validated.

📄 Abstract（原文）
To investigate the carbon footprint of bamboo-based activated carbon from different manufacturing pathways, this research evaluated cradle-to-gate manufacturing emissions under a unified system boundary and allocation baseline based on primary data from a 10,000 t/year continuous industrial production line. An LCA model was constructed and verified using an allocation ratio interval scanning method. Results showed that carbon footprints of granular, powdered, and extruded activated carbons were 184.76 kg CO2 e/t kg CO2 e/t, 236.75 kg CO2 e/t, and 293.36 kg CO2 e/t. Although these products shared identical carbonization and steam activation units, the carbon footprints from milling, molding, and binder inputs accounted for 25.01%, 41.48%, and 52.77% of the total emissions. Internal thermal energy recovery via by-product gas recycling decreased emissions by 81.7%, 77.7%, and 73.8%, respectively. Compared with traditional coal-based alternatives, bamboo-based products achieved a reduction in emissions of about 95%. This study provides scientific guidance for the low-carbon production process of bamboo-based activated carbon and demonstrates the potential of biomass substitution for climate change mitigation.
