Condensed tannin rich extract (CTE) isolated from grey alder bark is considered as potential as green adhesive for particleboards production. The adhesive potential and quality of particleboards made on the basis of pine sawdust and tannin derived adhesives (from 10 to 20% on dry sawdust mass) were evaluated by the static bending (bending strength and modulus of elasticity in bending (MOE)). Mechanical properties of particleboards prepared using CTE as an adhesive meet the demands of European standard (EN 312 (2010) for interior fittings used in dry medium.
Keywords: bark, deciduous trees, condensed tannins, green adhesive, particleboards
