UPM is a pioneer in decades-long research on the utilisation of lignin in resins, adhesives, bioplastics and polyurethanes, for example. Since 2017, lignin has been used as part of the WISA BioBond gluing technology in UPM Plywood’s production. As of today, lignin can replace approximately two thirds of the phenol typically used in the adhesive – and the target is to further increase this proportion.
UPM BioPiva™ lignin and the resin technology related to its use, developed and patented by UPM Biochemicals, are now supplied to many of the biggest resin producers worldwide, such as Prefere Resins in Europe. Prefere Resins is one of the frontrunners for lignin-based plywood-adhesives.
Prefere Resins’ Vice President of Technology, Dr. Michael Schwab, has been involved in lignin research for approximately 20 years.
