Abstract
It is well-known that the most (only) dynamic and profitable sector of the US steel industry is the so-called ‘mini-mills’ — exemplified by Nucor. These companies are essentially scrap processors and recyclers. At first they produced mainly rather low grades of steel products from iron and steel scrap. It is authoritatively estimated that 95 percent of the iron and steel embodied in products eventually returns as old scrap (Sibley et al. 1995). In recent years the recycling technology has improved significantly, and with it the quality of the products and the range of products in which recycled steel can be used. In the long run, as steel recycling technology improves further and global demand approaches saturation, it would seem that the so-called ‘integrated’ iron and steel producers, who start from iron ore, are facing gradual extinction, at least in the industrialized countries.KeywordsCopper ContentWaste StreamRecycling RateSteel ScrapDemolition WasteThese keywords were added by machine and not by the authors.
