The increase in high quality steel production in electric arc furnaces (EAFs) requires the use of scrap substitute materials, such as Direct Reduced Iron (DRI) and Hot Briquetted Iron (HBI). Although DRI and HBI products have lower copper and nickel contents than most scrap materials, they can contain up to ten times more phosphorus.

DRI-based reduction emits less carbon dioxide than the integrated method and enables the production of high-quality products in the EAF. High-quality products require the highest quality of steel scrap; if scrap is limited, the use of DRI is necessary to guarantee specific qualities. DRI production requires cheap and readily available natural gas.
