Bonding Plant Fibers with Uncondensed Lignin as Adhesive

Abstract

The development of wood adhesives using biomass resources holds significant importance for sustainable resource utilization and public health. Utilizing non-condensed lignin directly as a wood adhesive provides a new approach for the green, low-cost, and large-scale production of high-performance wood adhesives. This innovation has the potential to drive the green and low-carbon development of the wood/plant products industry.
