 · So Coal based DRI production is rampant which adds to very high coal consumption and GHG emission. India has also no supply of scrap and 5-6 million tonne scrap is imported annually to feed the EAF/IF units. Besides, imported scrap is also costlier as compared to Coal DRI. Thus, growth is mainly in Coal DRI-EAF/IF and BF-BOF routes.
