Which is more environmentally friendly- aluminum foil or parchment paper?
Parchment paper is bleached or unbleached paper coated with silicone. Tin foil is actually a thin layer of aluminium. Mining and processing aluminium takes a lot of energy and resources. And although clean foil can be recycled, once you pull it off something like a lasagna, you have to trash it. Parchment can’t be recycled, but is created from a renewable resource. It also has nonstick properties that most tin foil doesn’t. So parchment wins in the big picture. I’ve started using parchment paper when I bake cookies, roast vegetables, or broil fish.
Go one step further using silicone baking mats, which serve the same purpose and last for a long time. They’re on my shopping list to try out!
