Nanocellulose obtained from waste cellulose has a promising wide range of opportunities to obtain the superior material properties towards various end-products. Here, we report on waste cellulose material from used diapers subjected to an acid hydrolysis using sulfuric acid to obtain nanocellulose. The prepared nanocellulose was further characterized with the aid of different techniques to elucidate crystallinity (85% degree), purity and morphology of the obtained product.
