本論文は、EUのグリーンディールやバイオエコノミー戦略を背景に、バイオベース建築材料の可能性を包括的にレビューする。植物由来材料や菌糸体複合材など多様な材料を評価し、炭素隔離や循環経済適合性などの環境優位性を確認する一方、LCA手法の不統一や規格不足、高コストなどの障壁を指摘。さらに、2026年のホルムズ海峡危機を想定し、石油由来材料への依存リスクを強調する。移行には技術革新だけでなく、ガバナンスや政策の安定性が重要と結論づける。
English
This paper reviews bio-based construction materials in the context of the EU Green Deal and Bioeconomy Strategy, covering plant-based materials, bio-admixtures, nanocellulose, and mycelium composites. It finds significant environmental benefits including carbon sequestration and circularity, but identifies barriers such as inconsistent LCA methods, lack of standards, high costs, and fragmented supply chains. A hypothetical 2026 Strait of Hormuz crisis underscores supply security risks. The review concludes that overcoming barriers requires not only material innovation but also stable governance and policy coordination.

日本のGX文脈において
EUのバイオエコノミー戦略に焦点を当てたレビューであり、日本のGX政策（例：グリーン成長戦略）との直接的な関連は薄い。しかし、バイオマス材料の活用やLCA手法の課題は日本でも共通であり、特に建設分野の脱炭素化に向けた示唆を含む。
In the global GX context
This paper provides a comprehensive review of bio-based construction materials within the EU policy framework, highlighting environmental benefits and implementation barriers. It contributes to global GX discourse by linking material innovation with supply chain security and governance, though its EU-centric focus limits direct applicability to other regions.

📄 Abstract（原文）
The construction industry faces a dual imperative: continued growth to meet the demands of a rapidly expanding global population, and deep decarbonisation to align with planetary boundaries and climate commitments embedded in frameworks such as the European Green Deal and the EU Bioeconomy Strategy. This paper examines the potential of bio-based construction materials to bridge these competing demands, reviewing evidence across a broad spectrum of material categories — including fast-growing plant-based materials, bio-based admixtures and polymer composites for concrete, bio-based polyurethanes, nanocellulose and cellulose aerogels, plant-based biocomposites, and mycelium-based composites. The review demonstrates that bio-based materials offer compelling environmental advantages over conventional petrochemical-derived alternatives, including superior carbon sequestration potential, reduced embodied carbon, improved indoor environmental quality, and compatibility with circular economy principles. The strategic urgency of this transition has been rendered concrete by the 2026 Strait of Hormuz crisis, which triggered severe disruptions to global petrochemical supply chains and exposed the structural vulnerability of European construction to fossil-derived material inputs — reframing bio-based alternatives as a supply security imperative alongside an environmental one. However, the transition from demonstrator projects to mainstream specification practice remains constrained by persistent technical, economic, and regulatory barriers, including inconsistencies in life cycle assessment methodologies, the absence of harmonised performance standards, certification gaps, high initial costs, and fragmented supply chains. Crucially, the review identifies that resolving these barriers depends not only on continued material innovation but equally on governance configurations, policy stability, and actor coalitions, with the conditions under which green finance, circular procurement, and regulatory instruments successfully accelerate material adoption varying substantially depending on who orchestrates systemic coordination.
