The paper bags they give you on takeouts aren’t really eco-friendly because you need to cut down trees to make paper in the first place. The best solution to this problem is to use the reusable and BPA-free silicone foodbag from Compleat. It’s soft and can be rolled up to make it easier to stash until you need it. It’s dishwasher safe and you’ll look a lot more stylish carrying this bag rather than a crumpled brown paper bag that’s soaked and dripping with oil and all kinds of sticky stuff.
