Cow dung for the development of electrodes as an energy storage device!

IIT-ISM researchers have derived adsorbents that can help remove heavy metals from cow dung and these can be developed as electrodes for energy storage devices.

The research team led by Brijesh Kumar Mishra, Associate Professor in the Department of Environmental Engineering, assisted by Ganesh Chandra Nayak, Associate Professor in the Department of Chemistry and Dr. Sonalika, Associate Researcher in the Department of Environmental Engineering, worked on the project with the dual goals of ensuring water decontamination as well as energy conservation.

The team is working on developing a cost effective adsorbent derived from cow dung to remove heavy metals from water and the adsorbent can also be used later to develop an energy storage device. The research project which also fulfills the objective of the Swachh Bharat mission’s Gobardhan framework to help villages effectively manage their livestock and biodegradable waste, is also in line with the objectives of the central government’s Swajal program to provide food clean and safe drinking water. to the rural population.

“Cow dung is made up of several types of minerals such as phosphorus, nitrogen and carbon, which mainly come from lignin, cellulose and hemicellulose,” Professor Mishra said.

Giving the use of the adsorbent derived from cow dung for the development of electrodes as an energy storage device, Mishra said: “These energy storage devices, developed from waste material, would be very inexpensive and can be integrated with solar panels in rural areas, which can be used to light homes, roads, public toilets, etc. These devices are said to be affordable, durable and cleaner with no impact on the environment , did he declare.

Mishra said the importance of adsorbent derived from cow dung in countries such as India, Bangladesh and Malaysia which focus on agriculture and cattle breeding, cow dung is a viable option for generating energy storage devices, as each bovine generates approximately 9-15 kg of cow dung. per day.
