Lignin-based membrane fabricated with deep eutectic solventĪ. The resulting membrane had a molecular weight cut-off of 1.3 kg/mol, a range relevant to molecular separations in the pharmaceutical and chemical industry.

The crosslinking with 5% epoxide in an aqueous medium enhanced the membrane stability enabling its application in an aqueous and organic solvent medium. We propose a sustainable membrane fabrication using lignin fully dissolved in a green deep eutectic solvent (DES).

Lignin is a natural green polymer option however its low solubility in mild solvents has limited its processability into membranes. Membranes are currently mostly produced from petroleum-based polymers and organic solvents like dimethylformamide, which are not expected to be used in large amounts anymore. For sustainability reasons, the membrane fabrication itself needs to align with the 12 principles of green chemistry with low environmental impact, preferentially using natural polymers and green solvents. Membrane technology is a sustainable process of molecular separation and purification in the chemical and pharmaceutical industry, with lower energy consumption than traditional thermal methods.
