Bamboo, perennial woody grass, grows widely in zones with a wet season ranging from the tropics totemperate areas. It grows faster than any woody plant, and its uses have, since ancient times, ranged frombasic tools to industrial materials. Recently, some studies implied that bamboo has a potential as fiber crop forthe production of cellulose nanofibers. They have attracted significant interest because of their high Young’smodulus, high strength, and low coefficient of thermal expansion, combined with low weight, biodegradability,and renewability. Bamboo cell wall have some chemical specifies as woody grass species. This review describesthe chemical characterization of bamboo and bamboo fibers and its potential use as reinforcing material suchas cellulose nanofiber.
