Coke breeze consumption is reduced (40,000 tons/year less of coke breeze in integrated plant of 4 Mt/year hot metal production) and 50,000–12,000 tons CO 2 /year less by using 10% pre-reduced iron ore. NO X: NO X emissions can be reduced by using low nitrogen content combustibles as 90% vol.% of NO X comes from the fuel .
