ArcelorMittal S.A. is a multinational steel and mining company headquartered in Luxembourg. Formed in 2006 through the merger of Arcelor and Mittal Steel, it operates integrated and mini-mill facilities across the Americas, Europe, Africa, and Asia. The company produces flat and long carbon steel and tubular products, serving end markets such as automotive, construction, energy, packaging, appliances, and machinery. ArcelorMittal also owns and operates iron ore mining assets that support its steelmaking activities.
For the chemical value chain, ArcelorMittal is a significant upstream partner through the supply and valorization of steelmaking by-products and process gases (e.g., blast furnace and coke oven gases rich in CO and CO2). The company develops and deploys technologies to reduce emissions and improve circularity, including carbon capture and utilization, increased scrap recycling, electrification, and hydrogen-based direct reduced iron pathways. These initiatives enable the conversion of industrial gases into fuels and chemical intermediates and support broader decarbonization efforts across energy and materials systems.
