State of Art Manufacturing and Producing Nanocellulose from Agricultural Waste: A Review

This review article aims to identify current research areas in nanocellulose production from various agricultural waste materials. In the arena of sustainable materials, nano-sized cellulosic materials have achieved great curiosity from scientists and researchers. Nanocellulose is embellished with some remarkable properties like biodegradability, renewability, low density, low weight, high strength and high stiffness. Nanocellulose is a versatile material and show pertinence towards variety of applications such as heavy metals, pharmaceuticals, medicines, textiles, barrier, reinforcing polymers etc. This review is an effective tool to introduce numerous agricultural waste materials used for the extraction of different forms of nanocellulose viz. cellulose nanofibres and cellulose nanocrystals. The most common preparation methods of nanocellulose are oxidation, high pressure homogenization, refining, electrospinning, steam explosion, acid hydrolysis, enzymatic hydrolysis etc. This review emphasize upon acid hydrolysis as one of the most prominent approach to synthesize nanocellulose by utilizing agricultural waste. This strategy to materialize nanocellulose provides an outlook for the future perspectives in overcoming the global issues like stubble burning, curbing air pollution etc. in a facile manner.
