The Benefits of Recycling Steel | GLE Scrap Metal
One of the benefits of recycling steel is that it reduces the consumption, expenses, energy, and time to mine other valuable resources. For every ton of recycled steel, it saves one and a half tons of iron ore, half a ton of coal, and 40 percent of the water normally used in the production process. By using ferrous scrap rather than ...
