Recycling aluminum saves what percent of the energy needed to produce it from raw materials?

 Recycling aluminum saves about 90% of the energy needed to produce it from raw materials. This is because when aluminum is recycled, it doesn't need to go through the energy-intensive process of extracting it from bauxite ore. Instead, the recycled aluminum can be melted down and reused, which requires much less energy. This is why recycling aluminum is such a great way to conserve energy and reduce environmental impact. Plus, it also helps cut down on greenhouse gas emissions.
