What's the most eco-friendly choice for storing leftovers: plastic cling wrap or aluminum foil?
Judging by conversations the Lantern has had with her colleagues, most people seem to believe intuitively that aluminum foil is better for the planet, maybe because plastics are made from fossil fuels and we've heard so much about how they're polluting the oceans. Plus, foil can be rinsed and reused with relative ease, or sometimes even recycled at the curb, while plastic wrap is usually thrown away.
But as we discussed in our analysis of beer containers, aluminum has a heavy manufacturing footprint. It takes a whole lot of energy to mine bauxite ore from the Earth and then process it: Producing a ton of aluminum ingots requires 170 million British thermal units of energy and spits out about 12 tons of carbon dioxide-equivalent."
