Cellulosic materials are substances made primarily from cellulose, a natural polymer found in the cell walls of plants. These materials are abundant in nature and can be derived from sources like wood, cotton, and agricultural residues. They are known for their strength, flexibility, and biodegradability, making them useful in various applications. Common uses of cellulosic materials include paper, textiles, and packaging. In addition, they are increasingly being explored for sustainable alternatives in industries such as bioplastics and biofuels. Their renewable nature contributes to environmental sustainability, reducing reliance on fossil fuels and synthetic materials.
