You use it when you barbecue, cover your jars with it and wrap your leftovers in it. Aluminum foil is a great product that can accomplish various tasks. It also can go in your recycling! Be sure to rinse your foil and flatten it before disposing it into your recycling bin. Employees who sort our city's recycling are trained to throw away crumpled up foil, assuming it may contain food or other materials in it.
