IIT Mandi converts steel mills waste into useable products

Indian Institute of Technology, Mandi start-up is using green technology to convert steel mills waste into useable products.

Indian Institute of Technology, Mandi start-up has introduced green technology that does not require much energy, electricity or furnace. The technology is completely pollution-free. It converts waste from steel mills into useable products. Satinder Nath Gupta and his son Sandeep Gupta have started a company, Green Trek, a Jammu and Kashmir-based start-up, to use extractive metallurgy to address the problem of pollution.

According to officials, the team uses clean combustion techniques to trim the waste into the metal with high iron content which can then be reused by industries like shipbuilding, stone crushing plants, oil and gas plants, and power plants.

“We are working on a circular economy model by utilising extractive metallurgy whereby greenhouse gases are reduced and a sustainable waste management process is put in place,” Sandeep told PTI.

“The method we have devised uses less energy, uses no electricity or furnace and is 100 per cent pollution-free, and emits minimal greenhouse gases.

The end product is a molten metal with an iron content of 99.6 per cent which is then mixed with other metals to make various kinds of high-value steel and alloy castings used in a range of industries,” he added.
