日本語
本研究は、密閉型と開放型の堆肥化施設における一酸化炭素（CO）排出の可能性と動態を調査した。密閉型施設では、環境への排出削減という点で持続可能だが、労働者に対するCO濃度がEPAの暴露限界を超え、健康リスクが高まることが示された。堆肥の切り返し後には最大3000 mg CO/m3以上の濃度に達し、曝露時間が延長される。持続可能な廃棄物処理技術の導入には、労働安全のための継続的なガス監視が必要である。
English
This study investigates carbon monoxide (CO) emissions in enclosed and open composting facilities. Results show that while enclosed systems reduce environmental emissions, they lead to hazardous CO levels for workers, exceeding EPA limits and causing prolonged exposure. Continuous gas monitoring is essential to balance environmental sustainability and occupational safety.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の廃棄物処理施設でも、BAT（最適利用可能技術）の導入が進む中、労働安全の観点が軽視される可能性がある。本論文は、環境規制と安全規制の両立の重要性を示唆し、日本の廃棄物処理業界における統合的なリスク管理の必要性を提起する。
In the global GX context
This paper highlights a critical trade-off in waste management: environmentally beneficial enclosed systems can create occupational hazards. It underscores the need for integrated sustainability assessments that include worker safety, relevant for global waste treatment facilities adopting Best Available Techniques.

📄 Abstract（原文）
This study investigates carbon monoxide (CO) emission potential and kinetics in two biowaste composting facilities, one of which implements process hermetization in a closed hall, in accordance with the Best Available Techniques (BAT) for Waste Treatment, representing a more sustainable waste management approach due to the reduction in uncontrolled gaseous emissions to the environment. The flux chamber method was used to measure cumulative CO concentrations before and after compost turning across 10 compost piles located either indoors or outdoors. Maximum cumulative CO concentrations (CCOmax) and CO production rate constants (k) were calculated. Results indicate that indoor composting leads to significantly higher net CO emissions, both before and after pile turning. In all indoor piles, cumulative CO concentrations exceeded the United States Environmental Protection Agency (EPA) 1 h and 8 h exposure limits. Post-turning cumulative CO levels reached over 3000 mg CO·m−3, with averages ranging from above 15 to over 70 mg CO·m−3. These levels pose a serious health risk, potentially causing headaches, collapse, or even loss of consciousness in workers after approximately two hours of exposure. Additionally, compost turning in closed systems resulted in slower CO production, prolonging exposure. The study demonstrated that, although BAT-compliant enclosed systems are beneficial for the environment and support sustainable waste management practices, they may create hazardous conditions for workers. Therefore, continuous monitoring of gas concentrations is essential in closed composting facilities to ensure that environmentally sustainable waste treatment technologies are implemented together with adequate occupational safety measures, supporting a more comprehensive and balanced approach to sustainability.
