IISc has found an environmentally friendly way to recycle electronic waste
As per the United National Environmental Programme, there is about 50 million tonnes of electronic waste generated all over the world every year. In an endeavour to address this growing issue, researchers from the Indian Institute of Science (IISc) have found a method to recycle this humongous pile of e-waste in an environmentally friendly fashion. The method is also more efficient than those currently in use.
This new method involves the use of a ball mill at a very low temperature to reduce the electronic waste into nano-size particles. The temperature is very low, ranging from -50 to -150 degrees Celsius, which helps to eliminate any noxious emission. The e-waste is crushed into nano-size particles for around thirty minutes. In the process, the waste gets reduced to its constituent phases, and these crushed particles can then be separated without using any chemicals.
The idea for the method was thought of by Dr. Chandra Shekhar Tiwary from the Materials Engineering Department at IISc.
