WISA BioBond is the next step in the evolution of plywood: it replaces a minimum of 50% of the fossil-based phenol in the plywood’s glue with bio-based lignin, the tree’s own natural adhesive. The solution is now a standard in all of UPM’s WISA-Spruce plywood, helping you incorporate sustainable design further into your construction project.

Wood-based materials can help the building sector tackle climate change. WISA-Spruce plywood is an excellent material for specifiers targeting to reduce embodied carbon emissions: now WISA BioBond takes us a step closer to the ultimate goal of a construction material with zero fossil-based materials.


Construction-grade plywood evolved




New ideas, new technology, new recipe for a more sustainable future. WISA rewrites the playbook with the introduction of the WISA BioBond bonding solution. Soon the key ingredients for WISA plywood products – wood and glue – originate in the same place: responsibly managed forests. It is the best thing to happen to plywood since it was invented.



Bio-based lignin versus fossil-based phenol. Renewable raw material versus non-renewable. Anyway you look at it, WISA BioBond is the natural winner. The new bonding technology combined with UPM’s responsibly produced wood make WISA unmatched in sustainability. This makes it especially attractive for applications such as construction and indoor work and living environments where low emissions and sustainability are exceptionally important.



Rigorous field tests have proven that WISA plywood manufactured with the new lignin-based WISA BioBond bonding solution meets all the technical performance requirements for industrial-use plywood with flying colours. Market-leading WISA is a natural choice for all end-uses where excellent durability and outstanding strength-to-weight ratio is required. WISA BioBond is made to last.



Lignin is a class of complex organic polymers that form important structural materials in the support tissues of vascular plants and some algae. Lignin is present e.g. in trees as the internal “glue” filling the spaces in the cell wall between cellulose, hemicellulose, and pectin components. Chemically, lignins are cross-linked phenolic polymers.


How WISA BioBond is born

The story of the new bio-based bonding solution starts in responsibly managed forests. The process is a good example of UPM’s Biofore thinking which emphasizes resource efficiency and the innovative use of production residues to create added value.
