    Presentation title：
    Bio-Based High-Performance Adhesives and Biodegradable Hot Melt Adhesives

    Achieving sustainability in the adhesive industry can be approached through two main strategies: 1) manufacturing adhesives from renewable resources and 2) designing biodegradable adhesives. First, in the pursuit of sustainable adhesives from renewable resources, a variety of sources have been utilized. This approach has garnered attention from researchers both in the Republic of Korea and internationally. Notably, our lab has developed amino acid-based adhesives for bonding veneer and manufacturing medium-density fiberboard. Additionally, forest products have been explored for bio-based adhesives, leading to our previous development of tannin-based adhesives. Other renewable resources, including bio-oil, natural polymers, and agricultural products, have also been widely employed in the creation of bio-based adhesives. This presentation will highlight several examples of these materials. Second, sustainability in adhesives can be enhanced by designing them to degrade after use. Biodegradable polyester is a particularly promising candidate for manufacturing biodegradable adhesives. Our lab has developed biodegradable hot-melt adhesives specifically for packaging applications. We created poly(butylene succinate)-based hot melt adhesives by blending them with tackifiers, resulting in adhesives with adequate adhesion performance that can be removed after use. By incorporating a different base polymer, poly(butylene adipate-co-terephthalate), we significantly enhanced adhesive strength, making these adhesives suitable for packaging applications. This presentation will showcase various examples of hot-melt adhesives from our group and others, emphasizing the critical role of designing biodegradable adhesives for the future.
