Historically, adhesives were sourced from natural materials, but by the 20th century, they began to be synthesized from oil-based resources e.g. petroleum and natural gas, which offered durability for challenging conditions. However, the environmental impact of synthetic adhesives, which are derived from non-renewable resources, has sparked growing interest in more sustainable, bio-based adhesives made from renewable materials.
This course provides doctoral students with a comprehensive understanding of bio-based adhesives, focusing on their chemistry, performance, applications, and practical use in the wood products industry. Students will engage in both theoretical learning and hands-on laboratory work, including synthesizing adhesives, characterizing their properties, and applying them to the production of wood-based panels. By the end of the course, participants will be able to synthesise and test bio-based adhesives, fabricate and evaluate wood-based products, critically analyse recent advancements, and contribute innovative solutions to the industry.
For more information on the course please see the official SLU course page.
Registration to the course will open soon. Stay tuned!
The course is divided into seven modules, blending theoretical learning with hands-on practical experience to give doctoral studentsa well-rounded understanding of bio-based adhesives.
