Recycling aluminum saves about 90 percent of the energy it takes to make new aluminum, which is great since mining bauxite ore and turning it into aluminum is pretty environmentally destructive and energy-intensive. It takes about twice as much energy to produce new aluminum as it does to produce new plastic. - theverge
using recycled aluminum cans to make new aluminum cans uses 95% less energy than using bauxite ore, the raw material aluminum is made from.
