IIT Madras Researchers Develop Eco-Friendly Technology: Upcycle Paddy Waste to Manufacture Supercapacitors
A team of researchers from the Indian Institute of Technology Madras (IIT Madras) plans to convert agricultural waste, usually known as paddy waste, into a useful product for different industrial applications.
This eco-friendly technology will perform a major role in reducing burring of crop waste in North India and also benefit farmers by selling their field paddy waste to manufacture energy storage devices.
The researchers are promoting a new “Farm-Energy Synergy” from their previous work of utilizing organic waste, particularly kitchen waste, to create usable activated carbon, a main component in manufacturing supercapacitors. The same method they will imply to render paddy waste.
Every year in India, around 76,000 metric tons of paddy waste is produced because burning is the most economical and convenient option for dealing with agricultural waste.
Thus, creating a serious ecological issue. Also, burning limits the way that biomass can be used.
Supercapacitors made from activated carbon achieved from paddy waste will benefit customers in the energy, agriculture, and electronics industries and can promote industry self-sufficiency.
According to Project lead Dr Tiju Thomas, the produced activated carbon can become a commercially available industrial product with a specific energy of 4 Watt-hour per kilogram (Wh/kg) with a 5 volts range.
This supercapacitor can be used as a hybrid energy storage device. In addition to the energy sector, activated carbon has applications in water treatment, pharmaceutical, and biochar production industries.
