📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では国土交通省や国立研究機関が関与しており、下水道や農業排水への応用が期待される。バイオ炭のカーボンネガティブ特性は、日本のカーボンニュートラル目標（2050年）や循環経済政策に貢献しうる。ただし、GX実務（開示・金融）との直接連携は薄い。
In the global GX context
Globally, biochar is gaining attention as a carbon-negative technology with co-benefits for water treatment and soil health. This review provides a techno-economic and life-cycle perspective that supports circular economy and climate mitigation strategies. While not directly about disclosure or transition finance, it offers empirical evidence for carbon removal credits and sustainable sanitation in developing regions.

📄 Abstract（原文）
Purpose Biochar (BC), a high-carbon substance produced by thermally treating biomass, has emerged as a desirable, sustainable adsorbent for environmental clean-up, particularly for wastewater treatment. This review is an exhaustive survey of the literature, covering recent progress in biochar preparation, characterization and performance compared with traditional adsorbents such as activated carbon. Design/methodology/approach The structural and physicochemical properties of biochars, including pH, surface area, porosity and functional groups, which influence their capacity to adsorb pollutants, are given special attention. The discussion includes a sustainability evaluation via life cycle assessment (LCA) and carbon footprint analysis to demonstrate the potential for biochar systems to be carbon-negative and environmentally beneficial when produced from waste biomass. Findings Additionally, the study focuses on how BC can be recycled and regenerated across various treatment cycles, thereby increasing its lifespan. Cost–benefit analysis is used to assess the economic scalability of BC filters, especially in rural communities. Lastly, the possibility of incorporating BC into decentralized wastewater treatment units in off-grid, resource-constrained communities is described. Originality/value In general, this research highlights the triple role of BC in pollution removal, climate change mitigation and sustainable sanitation, making it a promising tool for the circular economy and rural environmental governance.
