📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では石炭火力の混焼・アンモニア混焼と並ぶ脱炭素オプションとして、バイオ炭や農業残渣活用がGX政策・地域循環経済の文脈で注目される。本レビューは国内の混焼実証や未利用バイオマス調達を検討する事業者・自治体にとって基礎的知見を提供する。
In the global GX context
Globally, biochar and torrefied biomass are positioned as transitional solid fuels for coal phase-down, relevant to power-sector decarbonization and circular bioeconomy strategies. The review contributes to disclosure scholarship by clarifying testing standards and coal-comparability metrics that underpin credible emissions accounting for biomass co-firing.

📄 Abstract（原文）
The continuous growth of the global population, urbanization and industrialization has led to a steep increase in worldwide energy demand, exerting immense pressure on conventional fossil fuel reserves. Fossil fuels currently dominate the global energy mix but are associated with severe environmental challenges such as greenhouse gas emissions, global warming and air pollution, highlighting the urgent need to explore sustainable and alternative energy sources. In response, renewable and sustainable energy resources have emerged as viable alternatives. Among these, biomass stands out as an abundant, carbon-neutral and renewable resource capable of producing valuable biofuels and bio-products. This review focuses on biomass availability, classification, composition, conversion pathways and the role of torrefaction and pyrolysis in producing energy-dense solid fuel biochar. The physicochemical characterization of biochar, its testing standards and its comparative performance with coal are discussed in detail. The paper further explores the applications of torrefied biomass, including its use as a co-firing agent in thermal power plants, feedstock for gasification and briquetting and a sustainable substitute for fossil coal in industrial and domestic heating. Moreover, the challenges and opportunities in biomass valorization are analyzed, emphasizing emerging opportunities in circular economy integration and decentralized energy systems. The study also identifies research gaps, particularly in optimizing process parameters for consistent biochar quality, developing cost-efficient torrefaction technologies and establishing standardized testing and classification methods. Overall, this review highlights the importance of optimizing thermochemical conversion processes to improve biochar yield and quality, contributing to clean, sustainable and circular bioenergy systems.
