Efficient Energy Usage
Reducing operational energy consumption is important to Qatar Steel, as it both benefits the environment and improves profitability. Internationally, burning coal is the most used energy source in steel production; however, this method has the greatest negative environmental impact. Qatar Steel uses natural gas, a much cleaner source of energy, putting the company ahead of competitors in terms of environmental impact. The company also follows a DR-EAF route for the production of steel, which is less energy intensive than other steelmaking routes followed widely in other parts of the world (i.e. BF (Blast Furnace)-BOF (Basic Oxygen Furnace)). In 2017, the company further reduced the energy intensity of its operations to 14.71 GJ/metric tonne of molten steel, a 4.0% reduction compared to 2016.
