How does recycling save energy? | American Geosciences .

Extracting and processing raw resources (wood, oil, ore) to make usable materials (paper, plastic, metal) requires a lot of energy. Recycling often saves energy because the products being recycled usually require much less processing to turn them into usable materials. Exactly how much energy is saved depends on the material in question. Let's take two examples: glass and aluminum.
