Nanocellulose Preparation from Sugarcane Bagasse and Its Application for Paper Sizing

The goal of this study was to fully utilize sugarcane bagasse, an abundant residue from the Vietnamese sugar industry that is also known as a potential source of lignocellulosic. The biomass material was used as a raw material to produce cellulose pulp followed by a hydrogen peroxide bleaching process. On the one hand, the unbleached cellulose pulp was used to make paper sheets with basis weights of around 100 g/m2. The bleached cellulose, on the other hand, was chemically and mechanically transformed into nano cellulose via a limited hydrolysis procedure. The obtained nano cellulose possessed a high crystallinity of 80.11% and was used for paper sizing to improve the mechanical and barrier properties of the paper. The ability of sugarcane bagasse nano cellulose-coated paper sheets to produce biodegradable containers for food and beverage applications was investigated.
