日本語
バイオマスからバイオエネルギーへの変換経路を、原料特性・変換技術・製品・プロセス性能・持続可能性の観点から体系的に整理したレビュー。熱化学的経路は迅速かつ製品柔軟性が高く、生化学・水熱経路は湿潤で生分解性の原料に有利と結論。持続可能性は変換収率だけでなく、エクセルギー効率・ライフサイクル影響・テクノエコノミクス・ロジスティクス・炭素管理の統合評価が必要と指摘する。AI/ML支援モデリング、デジタルツイン、BECCS、統合バイオリファイナリー等を今後の研究フロンティアとして提示。
English
A systematic review linking biomass feedstocks, conversion technologies, products, process performance, and sustainability. Thermochemical routes offer rapid conversion and product flexibility, while biochemical and hydrothermal routes suit wet, biodegradable feedstocks. Sustainability requires whole-system assessment—exergy, LCA, techno-economics, logistics, and carbon management—not yield alone. Emerging frontiers include AI/ML modelling, digital twins, BECCS, and integrated biorefineries.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本はバイオマス発電のFIT依存と燃料調達・持続可能性基準（GHG削減要件）が課題。本レビューは原料選定と炭素管理の統合枠組みを提供し、再エネ調達・Scope1削減戦略やSSBJ開示における脱炭素経路の根拠として参考になる。
In the global GX context
Under ISSB/CSRD, credible transition plans require technology-specific decarbonization evidence. This review's whole-system sustainability framing—LCA, exergy, techno-economics, BECCS—supports disclosure of biomass pathways as transition levers, though it does not itself address disclosure standards.

📄 Abstract（原文）
Biomass is a versatile renewable carbon resource capable of supplying heat, electricity, gaseous fuels, liquid biofuels, and carbon-rich co-products while supporting waste valorization and circular resource use. This review systematically examines biomass-to-bioenergy pathways by linking feedstock characteristics, conversion technologies, energy products, process performance, sustainability, and emerging research directions. Agricultural and forestry residues, energy crops, municipal and industrial biowastes, sewage sludge, and algal resources were evaluated alongside combustion, co-firing, pyrolysis, gasification, hydrothermal conversion, anaerobic digestion, fermentation, transesterification, and integrated conversion systems. The synthesis shows that feedstock moisture, ash chemistry, lignocellulosic composition, elemental properties, and biodegradability strongly govern technology suitability and product distribution. Thermochemical pathways offer rapid conversion and broad product flexibility, whereas biochemical and hydrothermal routes are particularly advantageous for wet and biodegradable feedstocks. Sustainability depends on whole-system performance rather than conversion yield alone, requiring simultaneous consideration of energy and exergy efficiency, life-cycle impacts, techno-economics, logistics, and carbon management. This present review also suggests that major research frontiers should include Artificial Intelligence (AI) and Machine Learning (ML)-assisted modelling, digital twins, advanced catalysis, integrated biorefineries, green-hydrogen coupling, bioenergy with carbon capture and storage (BECCS), and circular waste-to-energy systems. More importantly, a future framework is proposed that integrates feedstock intelligence, adaptive pretreatment, optimized conversion, selective upgrading, carbon management, digital optimization, and life-cycle and economic validation. In general, this review aims to support biomass-to-bioenergy conversion pathways toward scalable, credible, environmentally robust commercial deployment globally.
