Applications: This technology, an integrated process has been developed for the conversion of E-waste into fuel and recovery of metals. This technology works on the principle of low-temperature roasting in the presence of ammonium chloride. The available technologies use hydrochloric acid which is toxic but the usage of ammonium chloride is nontoxic and non-corrosive in nature, so there is no issue of storage and transportation. Ammonium chloride at higher temperature breaks into ammonia and hydrochloric acid, from which hydrochloric acid reacts with metals to form water soluble metal chlorides. Water was used as scrubber to absorb unreacted ammonia and hydrochloric acid. After roasting the residue mainly consists of metal chlorides which were leached with water to recover metals. The metal leach solution was then filtrated and analysed for recovery of metal.
Advantages: The consumption of electronic products has increased immensely and keeps on increasing at a high rate in every field of life. This rapid growth of the production of electrical and electronic products has meant an equally rapid growth in the amount of electronic waste. Electronic waste is now becoming one of the major factors for the deterioration of the environment. Heavy metals and plastic are the major components of electronic waste and account for 80 percent by weight and therefore, recovery of metals and therefore, recovery of metals develop a dire need to develop a technology which can deal with electronic waste. The technology has following advantages: Environment friendly process. Low temp. roasting technique No emission of toxic gases. This method is efficient to recover more than 95 percent of metal fraction. Single step process to recover metal fraction

I-Mitra(आई-मित्र) Welcomes You..
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
