Aluminum Cans vs. Glass Bottles
Because aluminum manufacturing is so taxing, glass bottles should be your drink container of choice.
Making cans is still less arduous than making glass bottles. Plus, aluminum wins big in shipping: An empty 12-ounce can weighs up to 14 times less than a 12-ounce glass bottle; less weight means less fuel and fewer emissions in transport. And after the drink's been consumed, aluminum wins again: Recycling ten pounds of aluminum can save 37 pounds of carbon emissions, compared with one pound saved through glass recycling. The verdict: six-pack ahoy!
