SCHNITZER STEEL INDUSTRIES, INC. 4 / Schnitzer Steel Industries, Inc. Form 10-K 2017 To prepare scrap metal, we crush, sort and bale the material by product grade for easier handling and sale. AMR processes mixed and large pieces of scrap metal into smaller pieces by crushing, torching, shearing, shredding and sorting, resulting in scrap metal pieces of a size, density and metal content required by customers to meet their production needs. The manufacturing process includes physical separation of ferrous and nonferrous materials through automated and manual processes into various sub- classifications, each of which has a value and metal content of importance to different customers for their end products. One of the most efficient ways to process and sort recycled scrap metal is through the use of shredding and separation systems. AMR operates six deep water port locations, five of which are equipped with large-scale shredders. AMR's largest port facilities in Everett, Massachusetts; Oakland, California; and Tacoma, Washington each operate a mega-shredder with 7,000 to 9,000 horsepower. Our port facilities in Salinas, Puerto Rico and Kapolei, Hawaii each operate a shredder with 1,500 to 6,000 horsepower. Our port facility in Providence, Rhode Island does not operate a shredder. Our shredders are designed to provide a denser product and, in conjunction with advanced separation equipment, a more refined form of ferrous scrap metal which is used efficiently by steel mills in the production of new steel. The shredding process reduces autobodies and other scrap metal into fist-size pieces of shredded recycled scrap metal. The shredded material is then carried by conveyor under magnetized drums that attract the ferrous scrapmetal and separate it from the nonferrous scrapmetal and other residue found in the shreddedmaterial, resulting in a consistent and high-quality shredded ferrous product. The nonferrous scrap metal and residue then pass through a series of additional mechanical sorting systems designed to separate the nonferrous metal from the residue. The remaining nonferrous metal is then further sorted by product and size grade before being sold. AMR invests in nonferrous metal extraction and separation technologies in order tomaximize the recoverability of valuable nonferrous metal.AMR also purchases nonferrous metal directly from industrial vendors and other suppliers and prepares this metal for shipment to customers by ship, rail or truck. Products AMR's primary products consist of recycled ferrous and nonferrous scrap metal. Ferrous recycled scrap metal is a key feedstock used in the production of finished steel and is largely categorized into heavy melting steel (“HMS”), plate and structural (“bonus”) and shredded scrap (“shred”), although there are various grades of each category depending on metal content and the size and consistency of individual pieces. These attributes affect the product’s relative value. Our nonferrous products include aluminum, copper, stainless steel, nickel, brass, titanium, lead, high temperature alloys and joint products such as zorba (primarily mixed aluminum nonferrous material) and zurik (predominantly stainless steel). Prior to the shredding process, AMR sells serviceable used auto parts from salvaged vehicles through its self-service auto parts stores located across the U.S. andWestern Canada. Each retail self-service store offers an extensive selection of vehicles (including domestic and foreign cars, vans and light trucks) from which customers can remove parts. We employ proprietary information technology systems to centrally manage and operate the geographically diverse network of auto parts stores, and we regularly rotate the inventory to provide customers with greater access to parts. In general, we believe the list prices of auto parts at our self-service stores are significantly lower than those offered at full-service auto dismantlers, retail car parts stores and car dealerships. Customers AMR sells its ferrous and nonferrous recycled metal products globally to steel mills, foundries and smelters. AMR's self-service auto parts stores also serve retail customers seeking to obtain serviceable used auto parts at a competitive price. Retail customers remove the parts without the assistance of store employees and pay a listed price for the part. AMR also supplies a small portion of its scrap metal to CSS's shredding operation in Portland, Oregon, the substantial majority of which is processed and delivered to CSS's steel mill.
