Traditional blast furnaces rely heavily on coke, a form of coal, to provide the carbon needed to reduce iron ore to iron. This process results in significant carbon emissions, contributing to the global climate crisis. However, flash ironmaking eliminates the need for coke entirely, creating a cleaner, more sustainable method of iron production.
