English
This review examines gas fermentation, which converts industrial waste gases (CO₂, CO, CH₄, syngas) into biodegradable biopolymers such as PLA, PHA, and PHB. It covers microbial pathways, genetic engineering for yield and cost gains, bioreactor scale-up, and the role of LCA and CCU in cutting emissions. Despite challenges like gas insolubility and higher costs than conventional plastics, it highlights policy and industrial momentum toward a circular, carbon-neutral plastics industry.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本はプラスチック資源循環法やグリーン成長戦略でバイオ素材・CCUを重点領域に位置づけており、素材メーカーや化学産業のScope 3削減・循環経済対応に直結する。国内の廃ガス発酵実装やLCA算定の議論に参照価値がある。
In the global GX context
Globally, this connects to ISSB/CSRD-driven Scope 3 and circular-economy disclosure, and to CCU pathways recognized under EU and US decarbonization policy. It offers disclosure scholars a materials-level example of how hard-to-abate plastics value chains can be reframed as carbon-utilization opportunities.

📄 Abstract（原文）
Plastic pollution is an escalating environmental concern, driving the urgent need for sustainable alternatives to conventional, petroleum-based plastics. Among the most promising solutions is the production of biopolymers, that is, natural polymers synthesized by living organisms such as microbes, plants, and animals. One innovative approach gaining attention is the use of gas fermentation technology, which converts industrial waste gases such as carbon dioxide (CO₂), carbon monoxide (CO), methane (CH₄), and syngas into valuable feedstocks for biopolymer production. This review delves into the integration of microbial fermentation processes with advanced bioreactor systems to efficiently produce biodegradable polymers, including polylactic acid (PLA), polyhydroxyalkanoates (PHAs), and polyhydroxybutyrate (PHB). Key microbial pathways and genetic engineering strategies are explored to enhance the yield, productivity, and cost-effectiveness of biopolymer synthesis. Additionally, this review emphasizes the importance of life cycle assessment (LCA) and carbon capture and utilization (CCU) for minimizing greenhouse gas emissions and improving the process’s overall sustainability. Despite the promise, several technological and economic challenges remain, including gas insolubility, difficulties with large-scale implementation, and higher production costs than traditional plastics. The review also examines environmental policies, industrial innovations, and global initiatives supporting a circular bioeconomy. Through case studies and recent advancements, it highlights the transformative potential of gas fermentation-derived biopolymers in building a sustainable, carbon-neutral future for the plastics industry.
