Production of Aluminum: The Hall-Héroult Process
Tossing an aluminum can wastes as much energy as pouring out half of that can's volume of gasoline. If each person recycles one aluminum can each month, energy savings equal 1,750 to 3,500 gallons of gas. American consumers and industry throw away enough aluminum to rebuild the entire U.S. commercial air fleet every three months.
