Abstract

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.
