Ecosteel USA is planning to build a new $240m steel mill complex in Miami-Dade County. The construction and engineering firm and building supplier intends to build the facility on 124 acres of land owned by the county outside the Homestead Air Reserve Base. The Ecosteel complex would be an “eco-friendly steel mill,” meaning it would use an electric furnace to melt scrap steel into billets. The company said it expects to produce about 1,000 tons of steel a day, and would include a rebar mill. The steel mill would reduce the need for trips to Jacksonville and Alabama, where most contractors get their rebar, beams and other supplies.
