本研究は、ココナッツ殻由来の活性炭と市販活性炭を比較するライフサイクルアセスメント（LCA）を実施。その結果、ココナッツ殻由来の活性炭は地球温暖化係数を66%、粒子状物質生成を70%削減することを示した。ただし、化学活性化剤による生態毒性の増加も確認され、より持続可能な代替手段の必要性が示唆された。全体として、バイオマス由来活性炭は低炭素で循環経済に適合する材料であると結論付けている。
English
This study conducts a cradle-to-gate LCA comparing coconut shell-derived activated carbon with commercial AC. Results show a 66% reduction in global warming potential and 70% decrease in particulate matter formation, attributed to renewable feedstock and lower energy use. However, higher ecotoxicity from chemical activators suggests a need for sustainable alternatives. Overall, biomass-derived AC offers a promising low-carbon route aligned with circular economy principles.

📄 Abstract（原文）
Activated carbon has grabbed attention of the researchers. Activated carbon production results in sustainability challenges, as it is heavily dependent on feedstocks which are fossil based. Besides, the steps require high energy. This research carries out a cradle to gate Life Cycle Assessment to compare AC derived from coconut shell with commercial AC. LCA focuses on climate change as well as overall Sustainability outcome. The precursor coconut shells were carbonized at 500-600 ºC. Afterwards; chemical activation was carried out using KOH. Inventory modeling was performed in OpenLCA 1.11 using the Ecoinvent 3.9 database. The results from LCA analysis indicates coconut-shell AC achieves mentionable reduction in environmental impacts. Results include a 66% lower global warming potential and a 70% decrease in particulate matter formation. Reduced energy consumption, renewable feedstock origin are reason for such benefits. Nonetheless, higher ecotoxicity impacts were observed due to the use of chemical activating agents, suggesting the need for more sustainable alternatives. Overall, the study confirms that biomass-derived AC offers a promising low-carbon route. Therefore; alignment with circular economy principles and advancing sustainable material development is found.
