パーム油燃料灰（POFA）とパームバイオマス由来バイオ炭を低炭素コンクリート材料として評価した2020〜2025年の文献レビュー。材料の変動性が採用を妨げる要因であるとし、起源・処理・微細構造・暴露依存の耐久性・認証の因果関係に焦点を移す。原料トレーサビリティから独立監視パイロットまでの5つの適格性ゲートと、インドネシア熱帯・沿岸での検証ロードマップ、耐用年数等価の炭素評価を提案する。
English
A critical review of 2020–2025 research on palm oil fuel ash (POFA) and palm-biomass biochar as lower-carbon concrete constituents. It reframes the issue from cement-replacement feasibility to causal links among residue origin, processing, microstructure, exposure-dependent durability and qualification. The authors propose five qualification gates—from source traceability to independently monitored pilots—plus an Indonesian tropical/coastal validation roadmap and service-life-equivalent carbon assessment, arguing reproducibility, durability and transparent climate accounting must govern certification.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
建設資材の低炭素化とScope 3排出量算定に関わる内容で、日本企業が東南アジアで調達・建設事業を展開する際のサプライチェーン排出管理やグリーン調達基準の参考になる。ただしSSBJ・有報開示との直接の接続は弱い。
In the global GX context
Speaks to embodied-carbon accounting and material certification in construction, relevant to Scope 3 category 1 and green procurement standards under CSRD/ISSB. Its call for transparent, service-life-equivalent climate accounting aligns with emerging building-sector disclosure expectations, though it does not engage disclosure frameworks directly.
👥 読者別の含意
🔬研究者:Provides a structured causal framework linking biomass residue processing to concrete durability and qualification criteria.
🏢実務担当者:Useful for construction and procurement teams assessing low-carbon material certification and embodied-carbon claims in supply chains.
🏛政策担当者:Offers a qualification-gate model that could inform standards for certifying variable low-carbon construction materials.
📄 Abstract（原文）
Palm oil fuel ash (POFA) and palm-biomass biochar have attracted interest as lower-carbon concrete constituents, yet material variability continues to impede confident engineering adoption. This critical qualitative literature review shifts attention from cement-replacement feasibility to the causal relationships among residue origin, processing, cement microstructure, exposure-dependent durability and qualification. Evidence from 2020–2025 journal research is interpreted across mineral-ash treatment, biochar pyrolysis, hydration kinetics, strength and deformation, chloride transport, carbonation, reinforcement corrosion and life-cycle performance. POFA primarily offers potentially reactive siliceous and packing functions; biochar introduces distinct porosity, moisture-management and carbon-retention functions. Neither has universally beneficial effects, and results from non-palm biochars should not be interpreted as direct validation of palm-residue formulations. The review proposes five qualification gates spanning source traceability and environmental safety, processing control, role-specific screening, exposure-based concrete verification and independently monitored pilot deployment. It also outlines an Indonesian tropical/coastal validation roadmap and recommends service-life-equivalent carbon assessment. The principal conclusion is that reproducibility, durability and transparent climate accounting—not impressive isolated strength gains—must determine whether variable palm-derived residues can become certifiable engineering constituents.
