Aluminum recycling is a good example as it takes about 5% of the energy to recycle aluminum back into a use from a can as it does to produce "new" aluminum from bauxite, the primary ore of aluminum. And that is a huge saving since aluminum smelting and refining is an energy hog to say the least... EDIT: Besides reducing the environmental impact as bauxite mines are usually large open pits. world-aluminium.org aluminum.org From above link.. <<<Recycled aluminum—from beverage cans to all other uses—requires only about 5 percent of energy as compared to primary-ore production. Americans’ recycling efforts and the industry’s aluminum reclamation system thereby reduces the overall energy consumption in total U.S. aluminum production by 46 percent. Primary production consumes 507.16 trillion BTUs for 8 billion pounds, and recycled secondary uses 41.3 trillion BTUs for 8.2 billion pounds, making the national industry energy consumption for production 548 trillion BTUs.>>>>
