The Assam Bio-Ethanol Private Limited (ABEPL) bio-refinery at Numaligarh, Assam, is India’s first commercial-scale project designed to produce second-generation ethanol from bamboo. The project links clean energy, rural livelihoods and sustainable use of biomass.

About the Project

• The project is implemented by Assam Bio-Ethanol Private Limited, a joint venture in which Numaligarh Refinery Limited holds 50%, while Fortum and Chempolis of Finland together hold the remaining 50%.
• The project is supported under the Pradhan Mantri JI-VAN Yojana, which promotes commercial production of advanced biofuels from lignocellulosic biomass and other non-food feedstocks.
• Unlike first-generation ethanol, which is generally produced from sugarcane, molasses or food-based feedstocks, second-generation ethanol is produced from agricultural and woody residues that do not directly compete with food production.
• The refinery is designed to process about 3 lakh tonnes of dry bamboo annually and produce around 49,000 tonnes of ethanol. 
• It will also generate furfural, acetic acid, food-grade liquid carbon dioxide and bio-coal/green power as co-products.
• The project aims to reduce dependence on imported crude oil, support ethanol blending with petrol, lower greenhouse-gas emissions and create additional income opportunities for bamboo farmers and rural entrepreneurs.

Why is it in the news?

The project has reportedly faced difficulties in achieving stable commercial operations, resulting in irregular bamboo procurement and underutilisation of several decentralised bamboo-chipping units. The project authorities have attributed the delay to the stabilisation process required for a first-of-its-kind bamboo-based 2G ethanol technology.

• The situation highlights the importance of a reliable biomass supply chain, technological stabilisation and financial protection for local entrepreneurs in large biofuel projects.

Policy Linkage

The National Policy on Biofuels, 2018, amended in 2022, promotes the use of lignocellulosic biomass and other non-food feedstocks for ethanol production. It supports India’s broader objective of increasing ethanol blending in petrol and improving energy security.

Key Takeaway 

The project represents the convergence of energy security, biofuel technology, rural livelihoods, bamboo-based economy, Northeast development and India’s low-carbon transition.
