Steel Dynamics introduced low-carbon steel grades BIOEDGE and EDGE

American steel company Steel Dynamics, Inc. (SDI) has announced the launch of new low-carbon steel products, BIOEDGE and EDGE, which support customers in achieving their goals of reducing greenhouse gas emissions and increasing production sustainability. This is stated in the company’s press release.

Both products are manufactured exclusively using electric arc furnaces (EAF), which already provide lower carbon emissions compared to traditional blast furnace technologies. Renewable energy sources are used for production – Green-e Energy certificates or carbon-free nuclear energy certificates, which significantly reduce Scope 2 emissions.

The BIOEDGE brand has an even lower carbon footprint, as it uses bio-carbon instead of anthracite in the smelting process, which reduces Scope 1 emissions. According to Mark Millett, Chairman and CEO of the company, the new products are an innovative solution for customers seeking real decarbonization of their supply chains without compromising on quality or performance.

The EDGE product line will be available at all SDI steel mills. The company expects high demand from the automotive, construction, energy, and infrastructure industries. Bio-carbon for BIOEDGE will be supplied by SDI Biocarbon Solutions, which is 75% owned by Steel Dynamics and 25% by Aymium.

Steel Dynamics posted strong results in the third quarter of 2025. The company’s revenue in July-September was $4.83 billion (+11.2% year-on-year), with net income of $403.9 million (+25.9% year-on-year). The company expects that improved market conditions, including increased trade stability and a more attractive interest rate environment, will contribute to strong domestic demand for steel and aluminum products.
