The shift from conventional to bio-based adhesives is helping to advance a circular bioeconomy by reducing dependency on finite resources. Fraunhofer WKI is at the forefront of researching alternative adhesive systems, including formaldehyde-free adhesives made from lignin and sugar aldehydes. One notable development is adhesives that leverage the natural bonding forces of wood, eliminating the need for traditional chemical adhesives. Reading tip: PolyurethanePolyurethane coatings play a vital role in many applications and still offer untapped development potential. The ongoing research and development at Fraunhofer WKI highlight the growing importance of bio-based adhesives as a key technology for sustainable industrial production and the circular economy.
