日本語

オイルパーム残渣（EFB、PKS、繊維、葉、幹）をバイオ炭・活性炭の原料へ転換する可能性を2020年以降の文献で整理した定性的レビュー。原料組成と熱化学処理条件が炭素収率・芳香族性・細孔構造・吸着性能・炭素安定性を左右する。活性化を強めると表面積は増えるが収率低下やエネルギー・試薬・排水負荷が増大し、持続可能性と両立しない点を指摘。原料・プロセス・製品のマッチングとLCAを伴う統合型オイルパーム炭素プラットフォームを提言する。

English

A qualitative review of whether oil-palm residues (EFB, PKS, fibre, fronds, trunks) can become feedstocks for biochar and engineered activated carbon, synthesizing literature from 2020 onward. Feedstock composition and thermochemical conditions jointly govern carbon yield, aromaticity, porosity, adsorption and carbon stability. The authors caution that maximizing surface area can undermine sustainability via lower yield and higher energy, reagent and wastewater burdens, and propose an integrated feedstock–process–product platform with credible life-cycle carbon accounting.

📄 Abstract（原文）

The rapid expansion of palm-oil processing has created a parallel challenge of managing large volumes of lignocellulosic residues, including empty fruit bunches, palm kernel shells, mesocarp fibre, oil palm fronds, and oil palm trunks. This qualitative literature review examines whether these residues can be repositioned from low-value wastes into feedstocks for biochar and engineered activated carbon. The review synthesizes recent literature published from 2020 onward across biomass conversion, materials engineering, environmental remediation, carbon sequestration, and techno-economic assessment. The evidence indicates that feedstock composition and thermochemical processing conditions jointly determine carbon yield, aromaticity, pore development, surface chemistry, adsorption performance, and long-term carbon stability. Biochar offers comparatively high carbon retention and promising applications in soils, nutrient management, remediation, and carbon sequestration, whereas further physical, chemical, or hybrid activation can produce higher-value porous carbons for wastewater purification, heavy-metal adsorption, organic-pollutant removal, CO₂ capture, gas purification, catalysis, and energy applications. However, maximum surface area is not synonymous with maximum sustainability because severe activation can reduce product yield and increase energy, reagent, washing, and wastewater burdens. The review therefore proposes an integrated oil-palm carbon platform based on feedstock–process–product matching, selective upgrading, coproduct energy recovery, credible life-cycle carbon accounting, and market segmentation. Such a portfolio approach can transform oil-palm residues into complementary agricultural, environmental, industrial, and climate products while strengthening circular-bioeconomy development.
