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.
