There is almost no household in the United States (and many other countries, for that matter) without paper towels. Our lives would seemingly come to a standstill without them. And it is impossible to imagine life without paper towels if you have kids or pets.
For those of you who are always looking for greens and browns for your compost pile, paper towels are often in the grey area. If you are new to the process, greens are green waste materials like fresh leaves, food scraps, grass clippings, tea bags, etc. which have a rich nitrogen content.
Browns are waste materials like dry leaves, hay, straw, pine needles, and pruning clippings that are rich in carbon. If you are wondering whether a paper towel qualifies, the answer is a bit more complicated than a simple yes or no.
Composting is a natural biological process that is used to break down organic matter and makes for excellent soil amendment material. It is also a great way to reduce methane emissions and do waste management efficiently so that not everything lands up in a landfill. The thing about paper towels is that they can be used to clean up a variety of things around the home. And that is where the answer to your question lies.
What’s Everything Made Of?
Paper towels in the kitchen are meant to absorb moisture. They are made of cellulose fibers which make it easy for bacteria to break them down. So, if you do not have cardboard or pieces of paper in your compost bin, you can use kitchen towels to control the moisture in your compost bin.
The only problem is that these paper products can restrict airflow because these small pieces of paper have bits of material that are excellent when it comes to absorbing water. While they can help with controlling moisture, they also get the decomposition started sooner than needed. If you throw larger bits of paper towels into the compost pile, they will absorb all the moisture and could create a problem with the airflow. They could also end up turning into clumps that create waterlogging in the bin.
So, most kitchen rolls made of cellulose fibers are not a great addition to the compost bin. Check the packaging for recycling details. They also should not be used as a replacement for shredded paper. But you can recycle the cardboard core of the roll as long as you tear it into tiny pieces. But that is not the end of the story.
Which Ones Definitely Don’t Work?
Paper towels are a generic term and not all of them are qualified for a place at the compost pile.
Some paper towels can be used for composting depending on what you have cleaned with them. The first rule is that towels that have been used for cleaning oil, chemical residue, and grease do not belong in the compost bin.
Oil and grease, as you know, can keep air out of the bin and create room for anaerobic bacteria. These are bacteria that do not grow or live when there is oxygen present. And if there is no oxygen in the bin, your decomposition process will not go as it should. It is necessary to keep your pile properly aerated. It also creates odors that do not belong in the compost pit. Yeah, bad smells that have no entry into a compost bin means things are really bad.
Then there are chemicals to consider. If your paper towels have come in contact with any kind of microorganisms or that chemicals typically contain, they might harm the good microbes that make composting possible. This is also true for towels that were used to clean dog poop which might just have disease-carrying pathogens that can kill essential micro and macro organisms.
There’s also you. If you have been using tissues because you have been sick or have a contagious disease, throwing those in the compost bin is a sure-fire way to harm your compost.
Which Products Are Compostable?
Now it is time to look at the kind of paper towels that you can toss into the compost bin without a care.
All paper towels that were used to clean up a dry mess are good to go. Whenever you clean your hands after washing them or wipe clean dishes or surfaces that do not have chemicals on them, you can throw them for composting.
These paper towels are considered to be brown matter and are rich with carbon. Some professional composters actually add paper towels into a separate bin and use that compost to cover soil on landfills. This process not only helps reduce paper waste but also improves the fertility levels and the texture of the soil. And when it is commercial, it also creates jobs.
But, even these paper towels are chemical-free. The idea is to make sure that towels that were used as food napkins and have bacteria on them will help with the decomposition. Usually, schools and airports with a program are well-placed to do this because towels in commercial bathrooms are perfect for composting.
Paper towels, though made from trees, take some time to decompose. As you would expect, the time it takes to break down depends on the thickness of the paper towel. It can take as long as a month for that to happen, sometimes faster if a compost accelerator is used. But if they are wet and worms are allowed to work their magic on them, you might get the results sooner than that. Many other household waste products can be composted rather than thrown into the trash, such as bread, rice, banana peels, eggshells, and citrus.
The Bottom Line of Composting Paper Towels
If you are looking at unused paper towels (for some reason) they are a safe choice for composting. These paper towels are rich in nitrogen and can do a better job here than in a landfill. But you must cut or shred them into small pieces so that they decompose quickly.
If they are not greasy or have been in contact with chemicals they are good to go. In fact, even the ones you use to blow your nose can go into the compost bin, as long as you are not carrying a contagious disease. While paper towels are so bright because they have bleach in them. If you knew that and were wondering, don’t worry about it. That goes into the compost bin.
