If you compost at home, you might be wondering if waxed paper is compostable. On the surface, it feels natural, and paper and wax are both natural materials. But sadly, the answer is no. Unless you are composting soy bean-based waxed paper, you’re likely using a petroleum-based product. Almost every waxed paper is coated in paraffin wax, which is derived from petroleum. And it’s this petroleum byproduct that makes conventional waxed paper both non-compostable and non-biodegradable. You can find soy bean wax-covered paper in some health food stores if you do want to make the eco switch.
