Polyurethane Adhesives Based on Oxyalkylated Kraft Lignin. [PDF]
Polymers (Basel), 2022 Lignin-based polyol was obtained via oxyalkylation reaction with propylene carbonate using eucalyptus kraft lignin isolated from the industrial cooking liquor by the Lignoboost® procedure. This lignin-based polyol (LBP) was used without purification in the preparation of polyurethane (PU) adhesives combined with polymeric 4,4′-methylenediphenyl ...

Lignin Valorization for Added-Value Chemicals: Kraft Lignin versus Lignin Fractions
ChemEngineering, 2023 Lignin is a raw material that can potentially be converted into valuable compounds through depolymerization reactions in addition to its use as a polymer or material. However, the chemical recalcitrance and the heterogeneous composition and structure of lignin make it challenging to establish processes that add value to this complex aromatic biopolymer.

Bacterial conversion of depolymerized Kraft lignin [PDF]
Biotechnology for Biofuels, 2019 Lignin is a potential feedstock for microbial conversion into various chemicals. However, the degradation rate of native or technical lignin is low, and depolymerization is needed to obtain reasonable conversion rates. In the current study, base-catalyzed depolymerization-using NaOH (5 wt%)-of softwood Kraft lignin was conducted in a continuous-flow ...
