Abstract
Organosolv lignins were extracted from lignocellulosic raw materials (Miscanthus x Giganteus and Empty Fruit Palm
Bunch) and condensed tannins were extracted from grape by-product in an aqueous medium using different catalysts.
Resin formulations with total polyphenolic contents (tannin and/or lignin) ranging from 70% to 95% of the total resin
solids content were employed for the elaboration of particleboards. Mixtures of glyoxylated lignin/tannin and pure
tannin were produced and tested. The importance of the nature of the basic reagent used for the extraction of tannins
from grape pomace was demonstrated. Most of the adhesives produced yielded good internal bond strength results of
the panels, enough to meet relevant international standard specifications for interior-grade panels (European Norm EN
312).
