India’s First Bamboo-Based Ethanol Plant

Published on 22 Nov 2025

• India recently inaugurated its first bamboo-based bioethanol plant in Golaghat, Assam.

• The balco and tulda varieties of bamboo, indigenous to the northeastern region, are preferred for their high alpha-cellulose content in the range of 40-60%.

• Bamboo is lignocellulosic, meaning its fibers contain sugars locked inside a woody structure, which need to be broken down to make bioethanol.

• Bioethanol from bamboo is made by industrially breaking down its fibers (lignocellulosic biomass) into sugars, fermenting the sugars into alcohol, and then purifying the alcohol for fuel.

• The bioethanol plant has been designed to also yield acetic acid, furfural from raw bamboo stock and food-grade liquid carbon dioxide.

• Acetic acid is generated through the fermentation and oxidation of ethanol derived from bamboo’s cellulose and hemicellulose.

• Furfural is produced by the acid hydrolysis and dehydration of hemicellulose’s pentose sugars (mainly xylose).

• Liquid carbon dioxide is captured and purified from the fermentation process’s gaseous byproducts.
