Mr. Aurindam Dey: announced its ambitious growth path and would like to
produce 40 million tonne by 2030. the similar strategy
has been adopted by many other steel companies in
the country. At the same time demand and production of
stainless steel is also growing in India, which indicates
the growing demand for ferroalloys. however, along
with the growth in the steel sector a serious attempt
is being made Worldwide to decarbonize the steel
industry which would be feasible only if the supply chain

ferrochrome making there is very little indirect reduction
and mostly it is direct reduction therefore the flue gases
contain a lot of cO. tata Steel is considering how to use
this cO rich gas in pre-reduction of the ore. It has also
been suggested that use of Dc arc furnace in place
of Ac arc would reduce energy consumption and as a
result cO2 emission during ferro-alloy production.
DrKundu also gave an idea for the ferroalloy industries
to expand its customer base from steel industry to other
industries as well. For example to mine one tonne of
