Harvesting, extracting, and processing the raw materials used to manufacture new products is an energy-intensive activity. Reducing or nearly eliminating the need for these processes, therefore, achieves huge savings in energy. Recycling aluminum cans, for example, saves 95 percent of the energy required to make the same amount of aluminum from its virgin source, bauxite. Making recycled steel saves 60%, recycled newspaper 40%, recycled plastics 70%, and recycled glass 40% of the energy needed to make products from raw materials. The amount of energy saved differs by material, but almost all recycling processes achieve significant energy savings compared to production using virgin materials.
