Synthesis of biopolymer materials based on cellulose isolated from lignocellulosic waste

Abstract

This study focuses on the synthesis of biodegradable biopolymer materials based on cellulose isolated from lignocellulosic waste. Agricultural residues were used as a renewable source for cellulose extraction, which was subsequently incorporated into a starch-based polymer matrix to obtain composite bioplastics. The synthesis process involved cellulose isolation, preparation of starch suspension, plasticization with glycerol, and formation of homogeneous polymer mixtures followed by casting and controlled drying. The influence of component ratios and processing conditions on the formation of bioplastic films was considered during the synthesis stage. The developed approach demonstrates the feasibility of producing biopolymer materials using locally available lignocellulosic resources through a simple and scalable synthesis method. The proposed technology can serve as a basis for environmentally friendly bioplastic production.
