Steel scrap recycling conserves raw materials energy and landfill space.The domestic steel industry recycles millions of metric tons per year of steel cans automobiles appliances construction materials and other steel products.The primary source of obsolete steel is the automobile.The remelting of scrap requires much less energy than the production of iron and steel products from iron ore.Consumption of iron and steel scrap by remelting reduces the burden on landfill disposal facilities and prevents the accumulation of abandoned steel products in the environment.
Steel can be cast into bars strips sheets nails spikes wire rods or pipes as needed by the intended user. Based on statistics from The 1992 Census of Manufacturing 1118 steel manufacturing facilities currently exist in the United States. Steel production is a

Steel is an alloy of iron usually containing less than 1 carbon. It is used most frequently in the automotive and construction industries. Steel can be cast into bars strips sheets nails spikes wire rods or pipes as needed by the intended user. Based on statistics from The 1992 Census of Manufacturing 1118 steel manufacturing facilities currently exist in the United States. Steel production is a 9.3 billion dollar industry and employs 241000 people.
The energy crisis of the 1970s made thermal efficiency in steel mills a priority. The furnaces used in integrated plants were very efficient however the common production practices needed to be improved. The large integrated plants of the 1950s and 1960s tended to produce steel in batches where iron ore was taken from start to finish. This causes some equipment to be idle while other equipment was in use. To help reduce energy use continuous casting methods were developed. By keeping blast funraces continually feed with iron ore heat is used more efficiently.
Integrated Iron and Steel Manufacturing National Emission Standards for Hazardous Air Pollutants
This rule establishesnational emission standards for hazardous air pollutants NESHAP for integrated iron and steel manufacturing facilities. The final standards establish emission limitations for hazardous air pollutants HAP emitted from new and existing sinter plants blast furnacesand basic oxygen process furnace BOPF shops. The final standards will implement section 112d of the Clean Air Act CAA by requiring all major sources to meet HAP emission standards reflecting application of the maximum achievable control technology MACT.
The HAP emitted by integrated iron and steel manufacturing facilities include metals primarily manganese and lead with small quantities of other metals and trace amounts of organic HAP such as polycyclic organic matter benzene and carbon disulfide. Exposure to these substances has been demonstrated to cause adverse health effects including chronic and acute disorders of the blood heart kidneys reproductive system and central nervous system.

The element iron Fe is one of the most abundant on earth but it does not occur in nature in useful metallic form. Iron ore is the term applied to a natural iron-bearing mineral in which the content of iron is sufficient to be commercially usable. Metallic iron from which steel is derived must be extracted from iron ore. By definition steel is a combination of iron
Iron production reached around 125000 tons per year in 1078 CE a sixfold increase over the output in 800 CE. Iron and steel were put to many uses ranging from nails and tools to the chains for suspension bridges and Buddhist statues. The army was a large consumer steel tips increased the effectiveness of Song arrows mass-production methods .
EPA promulgated the Iron and Steel IampS Effluent Guidelines and Standards 40 CFR Part 420 in 1974 and amended the regulation in 1976 1982 1984 2002 and 2005. The regulation covers any facility that is engaged in iron or steel manufacturing forming and finishing including coke manufacturing. EPA estimates there are 254 iron and steel facilities discharging directly to surface waters or indirectly through publicly owned treatment works POTWs.

Steel is made primarily in a two-step process. In theprimary steelmaking step liquid iron is converted into steel bythe basic oxygen furnace BOF processor by melting scrap steel or direct reduced ironDRI in an electric arc furnace. Secondary steelmaking is a refining process in which alloying metals are added and impurities are removed.
