Abstract: Nanocellulose can be extracted from variety of lignocellulosic bio resources like jute, flax, ramie, hemp, wood and by-products of agricultural crops via various methods. Among these bio resources, wood is the most suitable source for commercial level production of nanocellulose because of its abundance, easy availability, low cost and sustainable production. Various studies have been carried out to the synthesis of highly purified cellulose Nanofibers from cellulosic materials via chemical treatments, enzymatic treatments, high pressure homogenizing, Cryocrushing, grinding; as well as a combination of two or several of the before mentioned methods. Since wood is the main raw material for industrial level production of nanocellulose, a better understanding of currently available methods may help to find out even more efficient, economically viable and environmental friendly methods for isolation of nanocellulose from wood in future. In this context the present article reviews the possible isolation methods of nanocellulose from wood.
