日本語

本研究は、耐火性木製ドアと竹製ドアのカーボンフットプリントを比較評価。原材料段階が最大の排出源であり、加工ロス削減やリサイクル（特にバイオ炭）による資源効率改善が大きな削減ポテンシャルを持つことを示した。中国の竹・木材産業における5%の炭素損失削減で約352億kg CO2の削減が可能と試算。

English

This study compares the carbon footprint of fire-resistant wood and bamboo doors, finding raw materials as the main contributor (58-64%). It identifies significant mitigation potential through improved resource efficiency: reducing processing loss, extending lifespan, and recycling (especially biochar). A 5% reduction in carbon loss in China's wood/bamboo sector could save 35.2 billion kg CO2.

📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

中国のバイオベース製品のカーボンフットプリント評価事例として、日本企業が木質建材のScope 3算定やカーボンストック評価を行う際の参考になる。ただし、中国の国家規格に基づくため、日本のJIS規格との差異に注意が必要。

In the global GX context

This paper provides a detailed carbon footprint methodology for bio-based products, relevant to global Scope 3 accounting and product carbon footprint standards (e.g., ISO 14067). The comparison of end-of-life options, especially biochar for carbon storage, offers insights for circular economy and carbon removal strategies.

📄 Abstract（原文）

This study assesses carbon footprint (CF) and explores mitigation potentials through improved resource efficiency for fire-resistant wood doors (WFDs) and fire-resistant bamboo doors (BFDs). Both WFDs and BFDs are certified to the Chinese national fire resistance standard GB 12955-2024, ensuring the same core fire resistance performance and functional equivalence. Results show that WFDs have a slightly lower CF (806.04 kg CO2 e/m3) than BFDs (830.54 kg CO2 e/m3), where the raw material phase acts as the main contributor (58.57–64.32%). Crucially, significant mitigation potentials are identified by enhancing resource efficiency across the product life cycle through reducing processing loss, and extending service lifespan, and sustainable recycling. Approximately 35.2 billion kg CO2 will remain after reducing carbon loss by 5% in the Chinese wood/bamboo industrial sector. Recycling approaches (wood/bamboo panels, bio-based pellet fuel, and biochar) can be utilized with fewer emissions to economize bio-resources. The use of biochar provides greater carbon storage benefits and will help to limit the effects of climate change.
