SuperBark - Safe, sustainable and high performance adhesives and coatings from industrial softwood bark

The SuperBark project, a collaboration of 12 partners from 8 countries, aims to develop more than 95% bio-based adhesives and coatings using bark components (nanocellulose and polyphenols). The developed adhesives and coatings will replace current fossil-based solutions used in consumer products in the furniture, construction, transport, and packaging sectors. To accomplish this, the SuperBark project will use polyphenols extracted from tree bark using a new alkaline fractionation technology and cellulose nanofibrils derived from cellulose-rich bark residues. The Pulp and Paper Institute will be mainly involved in the development of barrier coatings for fibrous materials or packaging incorporating bark-derived nanocellulose.
