The full use of biomass plays a central role in transition
to a circular bioeconomy. Unlike non-biobased adsorbents,
which are criticized for high production costs and the
generation of secondary pollutants, lignin nanoparticles
(LNPs) are a cost-effective and environmentally benign
alternative for water treatment. In this study, LNPs were
demonstrated for the first time as multifunctional materials
for the adsorption and UV-light driven photocatalytic
degradation of methylene blue dye (MB) in water
