Ozonolysis of Lignin: From Extensive Degradation to Selective Ring‐Opening Oxidation
ChemSusChem, Volume 19, Issue 4, 25 February 2026.Despite its potential as a renewable feedstock, lignin, a major component of plant cell walls and a by‐product of the pulp and paper industry, has long been underutilized. Historically, pulp mills employed ozonolysis, a powerful oxidative process, to delignify cellulosic fibers and break down lignin.

Tailoring Biomass‐Derived Organosolv Lignin Derivatives for High‐Capacity Adsorption of Rhodamine B
ChemSusChem, Volume 19, Issue 4, 25 February 2026.Organosolv lignin derivatives modified with phenolic compounds were synthesized via a one‐step lignin‐first approach and evaluated as renewable adsorbents for removing Rhodamine B dye from water. Among them, resorcinol‐modified lignin showed the highest adsorption capacity (101 mg g−1), driven by high surface area, pore volume, and accessible hydroxyl ...

Kraft lignin based carbon fibres
, 2017 Research has been carried out at RISE Bioeconomy into converting lignin to carbon fibres, focusing on melt spinning of kraft lignin to filaments, which were subsequently converted to carbon fibres. New equipment has been installed to improve the properties of the lignin based carbon fibres and now it is possible to produce carbon fibres with equal or ...
