Advances in Cellulose Extraction from Banana Pseudo stem

The growing demand for sustainable, biodegradable alternatives to synthetic polymers has intensified interest in agro-waste materials as renewable sources of biopolymers. The banana pseudo stem, a typically discarded byproduct of banana cultivation, is a rich source of cellulose a key structural polysaccharide with wide-ranging industrial applications. This review highlights the significance of banana pseudo stem-derived cellulose, discussing its chemical composition, sustainability potential, and value addition. It provides a comparative overview of conventional and advanced extraction techniques, including chemical, enzymatic, mechanical, and green technologies such as ultrasound- and microwave-assisted methods. Key challenges in extraction, such as lignin removal, process optimization, and yield enhancement, are addressed. Finally, the review explores potential applications of extracted cellulose in fields such as biodegradable packaging, bio composites, biofilms, and pharmaceuticals, emphasizing its role in promoting circular economy practices and reducing environmental pollution.
