Purpose and goal
The purpose of this project is to establish an sustainable process aiming for an effective fractionation method of softwood bark and to explore the potential of using the obtained lignin, tannin and cellulose fractions to produce bio-based environmentally friendly adhesives, free of formaldehyde, phenol and isocyanates, for plywood production. The long-term goal is to develop a process that would generate additional income for the forest industry, i.e. supporting a transit to a Swedish biobased economy with increased resource efficiency.
Expected results and effects
A novel value-chains for softwood bark for the production of biobased adhesives for wood panels with low environmental impact Establishment of a process technology that can valorise lignocellulosic industrial side streams into high added-value products for new market applications Demonstrate the technical feasibility and characteristics regarding lignin, tannin and cellulose based adhesives in order to replace phenol-formaldehyde in certain applications A sustainable production concept with low environmental impacts that enables valorization of softwood bark
Planned approach and implementation
The project will be conducted during 6 months and led by Ulrika Rova from Luleå University of Technology. The project includes partners with expertise in forestry (Sveaskog), biomass pretreatment and fractionation (Luleå University of Technology), biocomposite and polymer production (Borås University and RISE SICOMP), as well as a global supplier of special packaging solutions (Nefab).
