Recycling steel is great for the environment, and it’s also one of the most valuable metals to recycle. If you want to make some extra money recycling metal, or you’re just interested in how scrap metal recycling works, steel is a great place to start learning.

What is steel?

 Steel is a highly versatile metal made by mixing iron with materials such as carbon. Because it is an alloy, or a metal made from a chemical mixture, it can be made in a wide variety of ways for different applications. It’s used in everything from household appliances like refrigerators and washer-dryers to cars to firearms to aviation and manufacturing equipment. There’s even plenty of steel being used under the ocean and in space right now!

Steel is also one of the best materials in the world to recycle. Because steel is so widely used, it is always worth something—and because it consists of so much iron, very little material is lost during the recycling process. This means that used steel appliances and components can easily be recycled into new steel appliances and components, which helps offset the environmental impact of mining new iron and producing new steel.

Because it’s one of the most valuable and eco-friendly metals to recycle, it is also the most widely recycled material—metal or otherwise—in the world. In the United States in 2000, over 60 million metric tons of steel were recycled. As recently as 2008, 83% of US steel was recycled.

Even though there’s a high supply, though, there’s an even higher demand for steel. This means that recycling your scrap steel can make you money while you help protect the environment at the same time.
