Recycle your aluminum cans!
Recycling saves money and it's great for the environment. Alcoa buys tons and tons of used cans from scrap dealers and other recyclers all over the world every day. You can be a part of it through curbside recycling, by selling cans to a local recycler, or by donating cans to charitable recycling programs. For more information, see these links:
