NSI and IISR Lucknow to collaborate to develop low cost technology for ethanol production

National Sugar Institute, Kanpur and Indian Institute of Sugarcane Research, Lucknow to jointly work on developing technology for production of second generation, 2G ethanol so as to enable country meeting its requirements for ethanol blending in petrol. India aims to achieve 20 per cent ethanol blending with petrol by 2025.

For the purpose, Dr. Rasappa Vishwanath, Director, Indian Institute of Sugarcane Research visited National Sugar Institute, Kanpur and discussed the matter with Shri Narendra Mohan, Director, and other scientists of National Sugar Institute, Kanpur. The two institute aim to develop a low cost technology for production of ethanol from bagasse which otherwise is used mainly as fuel for burning in boilers.

Sugar factories, even after meeting their own requirements save about five million metric ton of bagasse per annum which can be utilized for production of ethanol. For the purpose, the cellulose present in the bagasse is to be converted into ethanol and therefore apart from 2G, it is also known as cellulosic ethanol, said Shri Narendra Mohan, Director.
We will extend our studies on other abundantly available cheap raw materials and waste viz. wheat straw, rice straw and cotton stalk etc. too as utilization of these material in such a manner will also help in solving issues related to pollution due to stubble burning, he said.

2G ethanol production technologies have faced lot of challenges to be economically and technologically viable despite more than 100 pilot plant and tens of demonstration and commercial plant commissioned globally. Together, we aim to work out technology requiring lower capital and operational cost so as to ensure lower cost of production and making units viable, said Director, Indian Institute of Sugarcane Research.
