| Outline of Final Research Achievements |
Achieving a circular chemical industry based on forest-derived plant biomass is essential for decarbonization and carbon neutrality. In this study, the principal investigator developed a new process to obtain high-quality lignin and discovered that this lignin can be dispersed as fine particles in water. The lignin particles were analyzed and evaluated, demonstrating that size separation is feasible using a microfluidic device for flow separation based on particle size.

| Academic Significance and Societal Importance of the Research Achievements |
持続可能なエネルギーと有機資源の循環利用社会の実現には、森林を基盤とした植物バイオマスによる循環型化学産業が不可欠である。植物細胞壁の主要成分であるリグニンは、地球上でセルロースに次ぐ豊富な有機資源だが、その分離と利用には技術的な障壁が高い。本研究では、温和な条件で低変性のリグニンを抽出し、リグニンの自己組織化を利用した微粒子形成と新規分離法により、高性能素材原料として再生する革新技術を提案する。
