Srinagar: A Kashmiri researcher has developed a technique for converting walnut shells into carbon that can be used in batteries.
The research done by Dr Wahid Malik at Indian Institute of Science Education, Pune, has found that the shells can produce high-quality carbon for the anode part of battery.
According to Satishchandra Ogale, the supervisor of the research, the shells would first be cleansed then heated at 1,000 degrees Celsius temperature for about 4 to 5 hours.
This technique extracts carbon which is converted into paste form. At the lab testing stage, about 300 – 400 mg of battery grade carbon has been produced from one gram of powder from the shell.
As per this estimate about 3600 kg of carbon can be produced from the state. This much of carbon can produce of tons of batteries, as small battery requires only a mili gram of carbon, he added.
“Wahid who is a brilliant student came up with the idea that waste of walnuts can be used for making carbon. At the beginning of his Phd, he said since walnuts is produced in abundance in Jammu and Kashmir, the waste which at present is mostly not used for any purpose, can be converted into carbon,” Ogle told Kashmir Reader.
“Since the idea was brilliant and innovative, we gave him a nod. At the end of this Phd, he came with the findings which was mind boggling,” he added.
Ogle said the essence of the research, which was done in intra-displinary subject-Physics and Chemistry, is that the waste was converted into a product that can fetch good value, commercially.
At present, as per the figures of horticulture department, 266280 metric tons of walnuts are produced every year. According to Bahadur Khan, President Dry Fruit Association Kashmir, the shells used mostly in woodstoves, fetch around Rs 8 a kg.
“If the research turns to be success, it will give boost to the walnut economy and can be an alternative source of income for walnut farmers,” he said.
