In January, WP3.3 Fermentation published an article in Polymers titled “Sustainable materials from organosolv fibers and lignin, kraft fibers and their blends".
Reprecipitation of the lignin particles on organosolv fibers appeared to improve the properties of thermopressed handsheets, with potential to be used in thermoformed pulp products. Not only were the stiffness and strength better than for the reference fibers, i.e., softwood Kraft pulp, but the susceptibility to wetting was greatly reduced. This entails a promising potential for the product streams from organosolv pulping, which could contribute to develop more sustainable materials and packaging solutions.
