Baking or parchment paper can be bleached or unbleached, and most of the times, unbleached ones are biodegradable. Even both can be eco-friendly, but to make sure, you should check the manufacturer’s information. This info is usually under the specifications list or on either side of the packaging. If you found the product eco-friendly, you can easily home compost, biodegrade and even recycle it. However, if you have doubts, do not hesitate to contact the manufacturer via customer care.
