Two students of IIT-Kharagpur develops the paper battery using sewage water and bioethanol green energy from the bamboo shavings and grabbed the worlwide attention for their innovation.
One of the student, Ramya Veerubhotla who is a research scholar at Department of Biotechnology in IIT-Kharagpur, has developed a disposable and flexible battery which is made from paper that could generate power from the bacteria present in the sewage water.
The uniqueness of her innovation is that Battery is made up of paper and thus is very light as compared to other batteries which are usually heavy. The battery contains air cathode while anode is made up of carbon based material.
She told in interview, "The power generated from one cell is in the range of few microwatts. More cells means more power. Household devices is difficult to operate on this device but it can power the devices which requires comparitively low power than household devices. For more power, you can take more units and combine them."
She won the first prize and cash reward of ten lakh rupees at KPIT Sparkle, 2018 while presenting IIT-Kharagpur's 'Team Electrodes' among 12,000 other students from across the country.
Another student, Ankur Mehta who is a fourth-year undergraduate student of the Department of Chemical Engineering from IIT-Kharagpur, was awarded the “Best Presentation Certificate” in the 7th International Conference on Clean and Green Energy (ICCGE 2018) which was held in Paris from 7th to 9th February.
Ankur was awarded as the best speaker when he presented his research paper on "Kinetics of Deliginification and Enzymatic Hydrolysis of non-food lignocellulose (Bambusa bambos) for Cellulosic Biofuel Production".
Ankur's BTech project aims to produce bioethanol energy from bamboo shavings collected locally from the IIT-Kharagpur campus.
He said, "Bamboo is a plant which grows abundantly in tropical countries like India. This is the first ever serious attempt to generate biofuels from waste material like bamboo shavings. I am currently working on optimising the entire process of conversion of raw bamboo to useful biofuels".
