Cellulose, the most prevalent natural polymer derived from plants, wood, and microorganisms, is gaining popularity these days. Researchers have used a variety of ways to extract cellulose from plants, bacteria, algae, and other organisms, including mechanical, chemical, and chemical-mechanical treatments. Cellulose Nanocrystals (CNC), Cellulose Nanofibrils (CNF), and Microcrystalline Cellulose (MCC) have all been extracted and utilised for a variety of purposes, including food packaging, water purification, medicine delivery, and composites
