Our North America segment is composed primarily of a vertically integrated network of recycling facilities, steel mills and fabrication operations. Our strategy in North America is to optimize our vertically integrated value chain to maximize profitability while providing industry-leading customer service. To execute our strategy, we seek to (i) obtain inputs at the lowest possible cost, including materials procured from our recycling facilities, which are operated to provide low-cost scrap to our steel mills, (ii) operate modern, efficient EAF steel mills and (iii) enhance operational efficiency by utilizing our fabrication operations to optimize our steel mill volumes and obtain the highest possible selling prices to maximize metal margin. We strive to maximize cash flow generation through increased productivity, high-capacity utilization and optimal product mix. To remain competitive, we regularly make substantial capital expenditures. We have invested approximately 92%, 73% and 68% of total capital expenditures in our North America segment during 2022, 2021 and 2020, respectively. For logistics, we utilize a fleet of trucks we own or lease as well as private haulers, railcars, export containers and barges.

Our 38 scrap metal recycling facilities, primarily located in the Southeast and Central U.S., process ferrous and nonferrous scrap metals. These facilities purchase processed and unprocessed ferrous and nonferrous metals from a variety of sources including manufacturing and industrial plants, metal fabrication plants, electric utilities, machine shops, factories, refineries, shipyards, demolition businesses, automobile salvage firms, wrecking companies and retail individuals. Our recycling facilities utilize specialized equipment to efficiently process large volumes of ferrous material, including seven large machines capable of shredding obsolete automobiles or other sources of scrap metal. Certain facilities also have nonferrous downstream separation equipment, including extensive equipment at three of our facilities that reclaim metal from insulated copper wire, to allow us to capture more metal content. With the exception of precious metals, our scrap metal processing facilities recycle and process almost all types of metal. We sell ferrous and nonferrous scrap metals (collectively referred to as "raw materials") to steel mills and foundries, aluminum sheet and ingot manufacturers, brass and bronze ingot makers, copper refineries and mills, secondary lead smelters, specialty steel mills, high temperature  Give two different versions of responses.
