DigiLignin: Digitization of lignin polyurethane development Hasselt University
Lignin, the second most abundant biopolymer on Earth, is considered a promising renewable aromatic macro-polyol to replace the conventional fossil-derived polyols used in polyurethanes (PU). Despite the long history of lignin-PU synthesis, several issues prevent the widespread integration of lignin in PU products: lack of low molecular weight lignin fractions suitable for PU products formulation, and the intrinsic complexity of designing ...
