U. S. Steel has broken ground on a US$1.9 billion direct reduced iron (DRI) production plant at its Big River Steel Works campus in Osceola, Arkansas. Announced on October 30, 2026, the project will expand the company’s steelmaking operations. Additionally, it will connect Minnesota iron ore production with its electric arc furnace facilities in the United States.
The new plant is designed to produce direct reduced iron for use in steelmaking. It will sit beside Big River 2, allowing hot direct reduced iron to be transferred directly into adjacent electric arc furnaces.
The arrangement is intended to reduce material handling. It will also improve production efficiency and strengthen the company’s control over a critical steelmaking input.
U. S. Steel expects the investment to create approximately 200 permanent jobs and up to 2,000 construction jobs at peak. The project also includes about 35 full-time embedded contractor positions once operational. First production is expected in 2029, according to the selected technology supplier, Midrex Technologies.
Project Scope And Construction Details
The Osceola facility will form part of U. S. Steel’s wider Big River Steel Works complex in Mississippi County, northeastern Arkansas. The company announced the US$1.9 billion investment in April 2026 before breaking ground in October.
A similar expansion in the US steel industry is underway in North Carolina, where , US Forged Rings is developing an US$875 million steel manufacturing facility in Hertford County.
The Osceola Steel plant will use Midrex technology to produce up to 2.5 million metric tonnes of hot direct reduced iron and hot briquetted iron annually. The facility will supply hot DRI to neighbouring electric arc furnaces. Also it will produce hot briquetted iron for transport to other steelmaking facilities and potential merchant sales.
Direct reduced iron is produced by removing oxygen from iron ore without melting the material. The resulting iron-rich product can be used as feedstock in electric arc furnaces, which melt metallic materials to produce steel.
The project’s technology is intended to provide a more integrated production process. Hot DRI can be transferred directly into the adjacent furnaces, reducing the need to cool, store and reheat the material. This can lower energy consumption and support more efficient furnace operations.
The facility will also be capable of producing hot briquetted iron. This material is compacted into dense briquettes, making it easier and safer to handle and transport than hot DRI. It can serve as a metallic feedstock for other steelmaking operations.
Midrex Selected To Supply Production Technology
Midrex Technologies was selected in June 2026 to supply the plant’s direct reduction technology. The proposed MIDREX Flex plant will support production of hot DRI and hot briquetted iron.
The technology supplier expects first production in 2029. The final construction schedule will depend on engineering, equipment delivery, installation, commissioning and integration with the existing Big River Steel Works operations.
The Osceola Steel Plant project will require industrial process equipment, including the direct reduction plant, associated gas-handling systems, material conveying infrastructure, heat-management equipment, utilities and control systems. These systems will support the conversion of iron ore pellets into metallic feedstock for steel production.
The final configuration and detailed construction programme will be established as the project advances.
Linking Minnesota Iron Ore With Arkansas Steelmaking
A key objective is to strengthen U. S. Steel’s domestic mine-to-mill supply chain. The company’s Keetac operations in Minnesota have developed direct reduced iron-grade iron ore pellet capabilities. The new Arkansas plant will use this feedstock to produce DRI close to the steelmaking furnaces.
This arrangement will reduce the need to transport finished DRI over long distances before it reaches the electric arc furnaces. Also, it’s intended to improve supply reliability and give the company greater control over the quality and availability of metallic feedstock.
The investment builds on U. S. Steel’s earlier development of Big River Steel Works. The company acquired Big River Steel in 2021, and its US$3 billion Big River 2 expansion began producing steel in 2024.
The combined Big River Steel Works campus has four electric arc furnaces. It will also produce more than six million tons of steel annually. The DRI plant will add an upstream ironmaking stage to this existing production system.
Construction Jobs And Regional Economic Impact
The project is expected to support employment during construction and operation. U. S. Steel estimates that approximately 2,000 construction jobs will be created at peak. Also, it will create around 200 permanent jobs and 35 embedded contractor positions.
Additionally, the development reinforces Mississippi County’s role in the US steel industry. The area has attracted major steel manufacturing investments, supported by existing industrial facilities, infrastructure and a regional workforce experienced in steel production.
The Arkansas Economic Development Commission welcomed the investment as another expansion of the state’s industrial manufacturing base. The plant is expected to support supply-chain activity involving construction services, engineering, equipment supply, logistics and maintenance.
However, the estimated construction workforce represents peak employment rather than 2,000 permanent positions. The permanent workforce will be substantially smaller once the plant enters operation.
Steelmaking Efficiency And Emissions Considerations
Direct reduced iron is increasingly used as an alternative to conventional ironmaking. Traditional blast furnaces rely on coke and other carbon-intensive processes to remove oxygen from iron ore. However, direct reduction uses gas to remove oxygen while keeping the ore in a solid state.
Midrex states that its natural-gas-based process, combined with an electric melter, can cut carbon dioxide emissions by up to 50% compared with traditional blast furnace and basic oxygen furnace production. However, actual reductions depend on the reducing gas, electricity source, operating conditions and overall steelmaking configuration.
The project’s integration with electric arc furnaces could improve material efficiency and reduce energy requirements associated with cooling and reheating hot DRI. Nevertheless, the overall environmental benefit will depend on the facility’s operating fuel, electricity supply and production performance.
Osceola Steel Plant Project Outlook
The October 2026 groundbreaking marks a new phase in U. S. Steel’s investment at Big River Steel Works. Engineering, site preparation, construction, equipment installation and commissioning will precede the planned start of production in 2029.
Once operational, the facility is expected to provide a substantial domestic source of DRI for the company’s electric arc furnaces. Also,it will produce hot briquetted iron for other destinations, giving U. S. Steel more flexibility in managing its metallic feedstock supply.
The Osceola Steel Plant project represents a major industrial investment in Arkansas. Its delivery will depend on completing the process plant, integrating the new production line with existing steelmaking facilities and commissioning the technology before commercial operations begin.
