"Of course, art pieces aren’t the only by-products that metal recycling produces. Unlike glass or paper, metals can be melted down and recycled indefinitely without losing their strength or chemical properties. For example, a typical car body is composed of 25% recycled steel. Steel can also be reused to build train tracks or bridges, and to manufacture small tools like hammers and wires. With the help of scrap metal buyers like A&R Metal Recyclers, scrap metal recycling helps the environment because when less energy is used to manufacture metals from scratch, less greenhouse gas is released into the atmosphere. Recycling aluminum, for instance, reduces energy consumption by up to 92%. Reusing metals also conserves the finite supply of ores the planet has—recycling a ton of steel saves 2,500 pounds of iron ore from being used."
