IIT-BHU finds new method to generate bioethanol from potato peel

The research & development in the realm of green energy & waste management is gaining pace in India. In an important development, the researchers at the Indian Institute of Technology (IIT-BHU) have pioneered a method to produce bioethanol from potato peel waste. The new methodology now offers a dual solution to food waste and energy security.

The project investigates the potential of potato peel waste as a bioethanol feedstock and it was led by Dr. Abhishek Suresh Dhoble, Assistant Professor at the School of Biochemical Engineering, and student Unnati Gupta. The new method invented aligns with India’s push for energy independence and environmental sustainability.

Bioethanol, a renewable fuel, reduces reliance on imported crude oil and promotes cleaner energy alternatives. This initiative addresses food waste while contributing to sustainable energy solutions.

Dr. Abhishek Suresh Dhoble said that the growing emphasis on ethanol blending in petrol, which is projected to reach 20% by 2025-26, a move that aims to cut fossil fuel imports and lower costs.

India produces approximately 56 million tons of potatoes annually, with 8-10% processed into chips, fries, and dried products. However, due to inefficient storage, transport, and handling, 20-25%—equivalent to 11-14 million tons—goes to waste.

Dr. Dhoble emphasized the scalability of this bioethanol production method, noting its potential to enhance India’s energy security. By promoting sustainable biofuel practices, IIT-BHU is contributing to shaping the future of energy in India and globally.

Professor Amit Patra, Director of IIT-BHU, also commended Dr. Dhoble and his team, highlighting that their work underscores the institute’s dedication to global sustainability. He mentioned that the project reinforces IIT-BHU’s leadership in environmental research and innovation, addressing clean energy and food waste management while benefiting both the economy and the environment.

Recently, the Union Petroleum Minister Hardeep Singh Puri announced that India has achieved the ethanol blending in fuel to the tune of 16.9% and India has saved Rs 1.08 lakh crore in foreign exchange till date due to ethanol blending.
