Nucor Corporation, a Fortune 300 company headquartered in Charlotte, North Carolina, is the largest steel producer in the United States, and the largest of the so-called "mini-mill" steelmakers (those using electric arc furnaces to melt scrap steel, as opposed to companies operating integrated steel works with blast furnaces). Nucor is North America's largest recycler of any material, recycling one ton of steel every two seconds. The company's total annual steelmaking capacity roughly is 25 million tons. - Source: Wikipedia
