Fraunhofer WKI is at the forefront of pioneering research in the development of bio-based adhesives derived from renewable resources and bio-based waste materials, making a significant contribution to a more sustainable and circular economy. Adhesives are an essential material in numerous industries, ranging from automotive manufacturing to furniture production and packaging. As these industries expand, the demand for adhesives continues to rise, driving a growing market.
The shift from conventional chemical adhesives to bio-based alternatives is helping reduce dependency on finite resources, which is crucial for advancing the circular bioeconomy. The research team at Fraunhofer WKI is focusing on alternative adhesive systems, including formaldehyde-free adhesives made from lignin and sugar aldehydes, both of which come from renewable sources.
They are also testing the potential of humic substances, by-products from the PET alternative polyethylene furanoate (PEF), as a sustainable adhesive solution. Additionally, they are exploring adhesives that leverage the natural bonding forces of wood, aiming to eliminate the need for traditional chemical adhesives. These innovative solutions are particularly relevant for the wood industry, where the use of bio-based adhesives can greatly reduce environmental impact.
Fraunhofer WKI’s research extends beyond traditional adhesives to include bio-based solutions derived from fungal mycelium. This research explores the potential of mycelium-based adhesives for use in insulation material production, offering an eco-friendly alternative that could revolutionize the construction sector. Moreover, bio-inspired adhesives, which mimic natural bonding principles found in nature, are being tested for lightweight construction in the mobility sector.
These adhesives not only provide an environmentally friendly option compared to conventional products but also present opportunities to optimize resource use and enhance the recyclability of materials, making them highly attractive for industries focused on sustainability.
As part of its commitment to advancing the field, Fraunhofer WKI operates as an accredited testing facility for structural adhesives and provides specialized training through the WKI Academy. These courses equip professionals in wood construction and other related fields with the necessary knowledge to implement these new adhesive technologies effectively. The ongoing research and development efforts at Fraunhofer WKI highlight the growing importance of bio-based adhesives as a key technology that will drive sustainable industrial production while supporting the circular economy.
