Although steelmaking is considered a mature industry by most economic measures, high stakes investments continue to be made in scrap-fed electric arc furnace (EAF) steelmaking in North America.

When compared with the 2017 edition of Recycling Today’s list and map of EAF mills, our 2021 version displays several new facilities and increased melting capacity at others. EAF producers Nucor Corp., Steel Dynamics Inc. and Commercial Metals Co. (CMC) all have opened or are in the process of adding new sites. The large-tonnage Big River Steel mill in Arkansas also now appears on the list, as does the EAF mill recently completed by U.S. Steel Corp. in Fairfield, Alabama, as well as another EAF in Alabama that is being built by ArcelorMittal.

Other mills have changed names, as firms including CMC and Gerdau have bought, sold or swapped steelmaking assets. A few closures also have occurred in the EAF sector, with older mills in Hamilton, Ontario, and Rancho Cucamonga, California, among those that have been phased out permanently. (Several other EAF mills sit idle as 2021 begins.)

This year’s edition of the list and map also includes integrated mill complexes with blast or basic oxygen furnace (BOF) capacity. The number of integrated mills in the U.S. has shrunk steadily since the 1980s and into the 21st century, with just 10 active sites in the U.S. as 2021 gets underway. Once sprawling BOF production sites in Bethlehem, Pennsylvania; Sparrows Point, Maryland; Fairfield; and Ashland, Kentucky, have been victims of the replacement of BOF production with the EAF process.

The map of steel mills maintained by Recycling Today remains dynamic, and we urge readers who spot something that needs to be changed to please contact Senior Editor Brian Taylor at btaylor@gie.net.
