Our cans are coated in a thin layer of paint, and are totally plastic-free. It is not harmful to the environment and does not affect the infinitely recyclable properties of aluminum.nBefore cans are recycled in furnaces, recycling facilities remove the paint in a variety of ways. When paint is removed from the aluminum can, it is often used to heat the furnace that will then melt the aluminum for recycling. It’s one of our favorite sustainable magic tricks.
