Woody biomass, mainly comprised of cellulose, hemicellulose and lignin, has a unique hierarchically porous structure. Such unique hierarchically porous structure and components with rich functional groups provide a large multi-scale engineering space, and the regulation of its structure and components can improve the performance of woody biomass materials and even endow them with new functions. We aim to improving the energy efficiency and proccessability while lowering the carbon footprint of biomass processing through developing engineering strategies such as efficient enzyme-catalyzed treatment, green solvent treatment, rapid molding, 3D printing, microwave-assisted synthesis, machine learning-assisted synthesis, etc..
