Lignin is the second most abundant biopolymer in nature, after cellulose, and is found in the cell walls of various plant species (particularly in wood), agricultural residues, fruit peels, and other biopolymeric sources

The development of biobased and biodegradable materials for food packaging is a critical step toward reducing environmental impact and replacing petroleum-derived plastics

Due to the increasing environmental pollution caused by synthetic plastics, particularly in Mexico, there has been growing interest in the development of sustainable materials derived from biopolymers and agri-food waste

The development of cellulose-based nanomaterials with tailored surface properties is essential for advancing their integration into high-performance polymer nanocomposite systems
