本レビューは、低価値の農業・林業廃棄物を活性炭（AC）に変換する持続可能性とスケーラビリティを検討した。籾殻、とうもろこしの穂軸や茎、綿茎、果実の皮や種子、サトウキビバガス、おがくず、木材チップ、殻、樹皮などが有望な原料であり、一部は市販の石炭系ACを超える吸着能力を示す。物理的活性化法と化学的活性化法の二つの主要な製造方法があり、それぞれに長所と短所がある。実験室レベルでは有望だが、商業的なスケールアップには原料の安定供給や最適化などの課題が残る。
English
This review examines the sustainability and scalability of converting low-value agro-forestry waste into activated carbon (AC). Promising feedstocks include rice husks, corn cobs, and sugarcane bagasse, with some showing higher adsorption capacity than commercial coal-based AC. Production methods (physical and chemical) are compared. Despite lab-scale success, commercial scalability faces challenges in feedstock consistency, ash removal, and supply chain development. Future research should focus on advanced activation and circular production systems.

📄 Abstract（原文）
This review examined the sustainability and growth potential of converting low-value agro-forestry waste into activated carbon (AC). Various agricultural and forestry residues have been successfully converted into AC, with some demonstrating adsorption capacities greater than commercially available coal-based AC. Amongst the most effective raw materials for removing pollutants like heavy metals, dyes, oils are rice husks, corn cobs and stalks, cotton stalks, fruit peels and seeds, sugarcane bagasse, sawdust, woodchips, shells, and bark. AC production relies primarily on two methods: physical (carbonization followed by activation with gases) and chemical (simultaneous carbonization and activation using chemical agents) methods. Each method presents unique advantages and disadvantages related to the production efficiency and cost. While laboratory-scale results are promising, commercial scalability remains a challenge. Key obstacles include optimisation of activation methods, feedstock availability and consistency, ash removal as well as sustainable supply chain development. Further research should focus on addressing these challenges while exploring advanced activation technologies, high-value applications and circular AC production and regeneration systems through biorefineries. Resolving these challenges would not only reduce waste and mitigate environmental impact but also unlock new economic opportunities in the expanding global AC market.
