バイオマス由来活性炭のカーボンフットプリントをライフサイクル視点でレビューした論文。原料選択、賦活化法、輸送、エネルギー消費、薬品使用が環境性能に与える影響を整理し、LCAと炭素会計によるGHG定量化・ホットスポット特定・カーボンネガティブ評価を論じる。農業残渣は化石由来前駆体より環境負荷が低い傾向を示すが、持続可能性はプロセス設計や地域エネルギーシステムに強く依存する。水浄化、CO2回収、エネルギー貯蔵、土壌炭素隔離など多機能な応用可能性も示す。
English
This review examines the carbon footprint of biomass-derived activated carbon across its full life cycle, covering feedstock choice, activation methods, transport, energy use, and chemicals. It applies LCA and carbon accounting to quantify GHG emissions, identify hotspots, and assess carbon-negative potential. Agricultural residues generally show lower burdens than fossil precursors, but sustainability hinges on process design, regional energy systems, and methodological assumptions. Emerging uses span water treatment, CO2 capture, energy storage, and soil carbon sequestration.

📄 Abstract（原文）
Biomass-derived activated carbon has emerged as a sustainable alternative to conventional fossil-based activated carbon owing to its renewable origin, excellent adsorption performance, and potential to support circular bioeconomy and climate mitigation strategies. However, its overall environmental sustainability depends not only on the renewable nature of biomass feedstocks but also on greenhouse gas emissions generated throughout production, utilization, regeneration, and end-of-life management. This review critically reviews the carbon footprint of biomass-derived activated carbon from a life cycle perspective, emphasizing the influence of feedstock selection, production technologies, activation methods, transportation, energy consumption, and chemical utilization on environmental performance. The application of life cycle assessment (LCA) and carbon accounting frameworks for quantifying greenhouse gas emissions, identifying environmental hotspots, and evaluating carbon-negative potential is comprehensively discussed. Comparative analyses of diverse biomass feedstocks and recent experimental studies demonstrate that agricultural residues generally exhibit lower environmental burdens than fossil-derived precursors, although sustainability remains highly dependent on process design, regional energy systems, and methodological assumptions. Emerging applications in water purification, air pollution control, carbon dioxide capture, catalysis, energy storage, hydrogen storage, and soil carbon sequestration further illustrate the multifunctional role of biomass-derived activated carbon in sustainable development. Finally, current challenges, knowledge gaps, and future research priorities are highlighted to facilitate the development of low-carbon, resource-efficient, and industrially scalable activated carbon production systems.
