Recent Developments in Electrochemical Lignin Depolymerization Using Flow Systems: A Mini Review

ChemElectroChem, Volume 13, Issue 16, 18 August 2026.
This review summarizes the current state of the electrochemical depolymerization of lignin focusing on studies performed in flow cells. Three anodic strategies are distinguished: oxygen evolution reaction substitution for energy‐efficient hydrogen generation, nonselective oligomer production, and selective aromatic monomer synthesis, such as vanillin ...

Unraveling the Role of Lignin Oligomers Functionality for the Synthesis of Nonisocyanate Polyurethanes

ChemSusChem, Volume 19, Issue 15, 14 August 2026.
This study reports the synthesis of bio‐based nonisocyanate polyhydroxyurethanes from crude lignins and depolymerized lignin oligomers. The structure–properties relationships were largely explored and highlighted the key role of lignin functionality on the physical properties of the materials. Lignins are the main source of aromatic compounds in nature.

Kraft lignin/aromatic compound-induced promoters in white rot fungus Gelatoporia subvermispora

Journal of Wood Science
White rot fungi are the only organisms that can completely degrade lignin in the plant cell walls. However, the regulatory mechanisms controlling the expression of lignin-modifying enzyme (LME) genes are still obscure.

Sustainable Photoelectrochemical Direct Lignin Upcycling via Ni‐Co Phthalocyanine Catalysts Integrated With Organic Semiconductors

EcoMat, Volume 8, Issue 8, August 2026.
An integrated photoelectrochemical system combining Ni‐Co phthalocyanines with organic semiconductors directly oxidizes kraft lignin with long‐term stability. The system promotes efficient lignin oxidation, enables tunable reactivity between vanillin and vanillic acid, and achieves high photocurrent densities.

Synthesis of Polyols for Expanded Rigid Polyurethanes by Microwave Liquefaction of Kraft Lignin With Bio‐Based Solvents

Macromolecular Materials and Engineering, Volume 311, Issue 8, August 2026.
This study produced bio‐based polyols from lignin using microwave liquefaction with bio‐derived solvents. The process was optimized by adjusting solvent composition and catalyst type to obtain high yields and a suitable hydroxyl number. Foams made from lignin‐based polyols showed comparable properties to commercial products.

High‐Shear Mixing of Softwood Kraft Lignin in Aqueous Sodium Lignosulfonate: Stable Suspensions, Efficient Emulsification and Controlled Curing of Epoxy Adhesives

Macromolecular Materials and Engineering, Volume 311, Issue 8, August 2026.
Blending sodium lignosulfonate with softwood kraft lignin generates stable, high‐consistency aqueous suspensions. The lignosulfonate efficiently coats and disperses the kraft lignin particles, producing a thick, extrudable paste. This fully bio‐based, solvent‐free approach demonstrates great potential as a sustainable wood adhesive, paving the way for ...
