英文摘要	Wood is a renewable and eco-friendly resource with great promise to advance sustainability in various industries, particularly those associated with construction and building materials. To maximize wood uses, here we show a processing route that transforms low-value wood (residual, damaged, decayed, disposed or fractured) into lightweight and strong structural materials. The process involves delignification, combined with partial dissolution and regeneration, to expose cellulose fibrils originally present in the cell walls. The latter form strong hydrogen bonding networks at interphases, leading to a 'healed' wood with a mechanical strength that exceeds that of typical metals and commercial laminated wood. Moreover, recyclability as well as excellent resistance against organic solvents are demonstrated, providing a promising valorization and sustainability pathway for low-value wood. Wood is one of the most renewable materials with applications in construction and other industries. The authors show a process that gives low-value wood and biomass residuals a new life by transforming them into materials with mechanical properties comparable to metals and other structural elements.
