Paper bags can be added to a home composting bin as a source of carbon, but not the ones waxed! Paper bags may take longer to break down than other organic materials, depending on the thickness and type of paper used.
If you do decide to add paper bags to your compost bin, it's a good idea to shred them first to help them break down more quickly.
You should also mix them well with other materials in the compost bin, as having too much of any one type of material can lead to imbalanced compost.
Finally, be sure to keep an eye on your compost bin and turn it regularly to help ensure that the materials are breaking down properly.
In general, it's a good idea to avoid adding items to your compost bin that are coated with plastic or other synthetic materials, as these materials may not break down in a home composting system.
It's also important to avoid adding items that may contain chemicals, such as glossy paper or colored paper, as these chemicals may not break down properly and could potentially contaminate the compost.
