Environmentally Friendly Production of Cellulose Nanofibers Using Laser-Assisted Lignocellulose Decomposition

An eco-friendly approach for producing cellulose nanofibers (CNFs) through laser treatment of lignocellulose nanofibers (LCNFs) is presented.Traditional CNF production methods require large amounts of organic solvents.Additionally, these methods lack flexibility in adjusting the ratios of cellulose, hemicellulose, and lignin, necessitating ratio control during pulping, which can impact subsequent stages.In contrast, this method reduces solvent use significantly and allows control over lignin content by adjusting laser irradiation time.Analytical techniques, including UV-vis, 13 C NMR, SEM, and XRD confirmed that laser treatment selectively decomposes lignin and other xylan residues while maintaining CNF structure.This method offers a promising, sustainable alternative for CNF production with notable environmental benefits
