Recently, Professor Peng Feng's team from the College of Materials Science and Technology at Beijing Forestry University published a groundbreaking research finding online in *Nature Sustainability* (IF 25.7), a top journal in the field of environment and sustainable development. Beijing Forestry University is the sole corresponding institution for this paper. Based on their long-term accumulation in the chemical modification and functional transformation of hemicellulose, the team successfully developed a high-performance, reusable bio-based hot melt adhesive (XA) using crystalline xylan, an industrial byproduct, as raw material. This not only provides innovative ideas for the design of novel biomass-based adhesives but also offers new ideas and technologies for the high-value utilization of hemicellulose. Xylan-based hemicellulose is an important natural polymer in plant cell walls, forming the main components of lignocellulose biomass along with cellulose and lignin. Hemicellulose is the second largest renewable carbohydrate resource after cellulose, abundant in crop straw and forest biomass. However, during the production processes of pulp and paper manufacturing and bioethanol manufacturing, most of the hemicellulose is degraded or dissolved after pretreatment, thus failing to be effectively utilized.
