— Why do we use coal to make steel? ... but also that coal isn't burned when making steel! (It most definitely is). For example, this analysis concludes that natural-gas-based direct reduced iron – electric arc furnace processes have carbon emissions per tonne of steel half that of typical coal-based processes. Carbon emissions from this ...
Metallurgical coal is an essential ingredient in the production of steel, making it one of the most widely used building materials on earth. It takes around 770 kilograms of coal to make one ton of steel, with approximately 70 per cent of global steel produced in basic oxygen …
