For preference I use Silpats in baking, but I wash and re-use parchment, foil, and even plastic wrap (obvs not in cooking, but in wrapping up baked goods), if I can get them clean enough, and then recycle what can be. Over and over until they fall apart. Saving the environment, even just a little, because every bit helps. About the only one I don't reuse is waxed paper, because it's too fragile; as a result, I use it very rarely, if ever.
