A growing global population and a fast-industrializing world are putting strains on our planet’s natural resources. Trends regarding urbanization and infrastructure development show no signs of slowing, making it more important than ever that we make efficient use of resources that are in finite supply. One of those dwindling resources is iron ore, which is combined with other materials to make steel.
Electric arc furnace (EAF) and ladle refining furnace technologies, unlike conventional basic oxygen furnaces, use electric power to remanufacture steel from scrap metal rather than virgin ore. This saves energy and natural resources and reduces emissions.
As scrap steel can be recycled endlessly, EAF technology has a long-term beneficial impact on the environment. Over 90 percent of the raw material processed at Cascade Steel is recycled scrap metal, with the remainder consisting of alloys that allow us to tailor our products to unique customer specifications.
We are continually refining the technologies that support our EAF, including supersonic burners, off-gas recovery systems, and software systems that allow us to manage heat more effectively and efficiently.
We also find sustainable uses for the by-products of our steelmaking process, which may be sold for reprocessing and other industrial applications.
When our steel products, including straight and coiled reinforcing bar, are shaped, cooled, and ready for sale, they are transported efficiently to our valued customers. For example, our mill has direct access to rail service that provides a lower-emission mode of transport than road vehicles. Because our steel products are made from recycled materials that are often sourced within 50 miles of our Cascade Steel facility, they can be used in construction projects working toward green-building certifications such as LEED. From recycled inputs to efficient outputs, we enable resource conservation at every step.
