Researchers at IIT BHU have developed a novel method for producing bio-ethanol from potato peel waste. This “waste to wealth” initiative not only presents a pathway for reducing food waste but also contributes significantly to India’s energy independence and environmental sustainability.
The research was conducted by Dr. Abhishek Suresh Dhoble, Assistant Professor at the School of Biochemical Engineering, and M.Tech. student Unnati Gupta, who explored the potential of using potato peel waste as a raw material for bio-ethanol production. Bio-ethanol, a renewable biofuel, plays a crucial role in reducing the country’s dependence on crude oil imports and promoting clean, sustainable energy alternatives.
Waste to Energy Research
Student Unnati Gupta explained that they created a paste from waste potato peels and then converted it into powder form. The process involves microbial consumption of the processed waste, which is then charged to produce bio-ethanol. The entire research focuses on the waste-to-energy conversion principle.

Reducing Fossil Fuel Import Bills
Dr. Abhishek Suresh Dhoble highlighted that ethanol blending in petrol has increased from 1.53% in 2014 to 15% in 2024, with a target of reaching 20% by 2025. Additionally, research is being conducted to evaluate the feasibility of 15% ethanol blending in diesel. These efforts are part of the government’s broader strategy to reduce India’s annual fossil fuel import bill of 22 lakh crores, especially in light of global geopolitical instabilities.
India produces an average of 56 million tons of potatoes, with approximately 8-10% (about 5 million tons) being processed into chips, fries, and dehydrated products. However, post-harvest losses in potato production can reach 20-25% (11-14 million tons) due to inadequate storage facilities, improper transportation, and handling.
International Recognition
Unnati Gupta received recognition for this research at the first International Conference on “Recent Trends in Environmental Science, Remote Sensing and Climate Change (WSRSCC-2024)” held at IIT Jammu, where she presented their findings.
Future of Sustainable Energy
Institute Director Professor Amit Patra congratulated Dr. Abhishek Suresh Dhoble and his team for this innovative initiative, noting that the research demonstrates their commitment to advancing cutting-edge solutions in support of global sustainability goals while strengthening the institute’s leading role in environmental research and innovation. This project aims not only to create a clean and sustainable energy future but also addresses the larger issue of food waste management, providing comprehensive benefits for both the environment and economy.
