Ever since the mandatory conversion to digital TV — the proverbial death knell to rabbit ear television antennas — I’ve wondered if aluminum foil sales have plummeted.

If you grew up with rabbit ears, you know what I’m talking about. Who didn’t fashion aluminum foil into a homemade antennae appendage in hope of enhancing the reception of their rabbit ears? I was never convinced that it worked, but at least it gave us something to do, since we couldn’t see what was happening on the screen.

Even with the demise of rabbit ears, aluminum foil sales are still big business. Over 1.3 billion pounds of aluminum foil is produced every year in the U.S. — that’s a heck of a lot of leftovers. While aluminum foil is just as recyclable as aluminum cans, many curbside recycling programs won’t accept it for sanitary reasons (check with your local recycling program for their foil policy). That’s a shame, because recycling aluminum uses only about 5% of the energy that it takes to produce aluminum from raw materials.

Alas, until aluminum foil recycling becomes more commonplace, here are some ways to get the most mileage — and most value for your money — from your aluminum foil by using it more than once:

* Wash it and use it again (and again): I swear my mother is still reusing foil from the time of Christ for wrapping and rewrapping leftovers in the fridge. Just wash it in soap and water, flatten it out with a rolling pin on the kitchen counter, and it’s good as new. (Caution: Foil that has come in contact with raw meat should not be reused for other food purposes.)
