Industrial History: C-C/AM/.../Bethlehem Steel Burns Harbor
Bankrupt Bethlehem Steel was bought by ISG for $1.5 billion in 2003, and Mittal bought ISG for $4.5 billion in 2004. So like the big mill at Indiana Harbor, Burns Harbor is also owned by ArcelorMittal, the largest steel company in the world, based in Luxembourg. (These photos are kinda old because the NIPSCO Bailey Power Plant is still active.)

Decarbonization in steel | McKinsey
Steel can be produced via two main processes: either using an integrated blast furnace (BF)/basic oxygen furnace (BOF) or an electric arc furnace (EAF). While integrated players produce steel from iron ore and need coal as a reductant, EAF producers use steel scrap or direct reduced iron (DRI) as their main raw material.
