A Novel Acid-Based Ternary Natural Deep-Eutectic Solvent for a Lignin-First Biomass Pretreatment Strategy
Short Introductive summary
Eucalyptus is a relevant pulp and paper feedstock. Its fines are an underutilized lignocellulosic resource already available in the industrial facilities. This study uses a novel ternary NADES (choline chloride, acetic acid, glycolic acid) for selective lignin extraction (80% purity) from fines, achieving ~90% delignification. The holocellulose-rich residue (~80%) is promising for further valorization, supporting sustainable biorefinery development. This green, tunable fractionation highlights solvent design’s role in efficient lignin recovery and integrated biomass upgrading.
