An aluminum can takes around 200 years to break down in nature. But that number tells only half the story — because aluminum is one material that never needs to be wasted.
Why does it take this long?
Aluminum can be recycled endlessly with no loss of quality, using a fraction of the energy of making it new. A littered can is therefore a double loss: 200 years of pollution, and a valuable resource thrown away. A recycled can is often back on a shelf within weeks.
