Paper towels can go in your compost bin, but only if they are unbleached and free of food oils or chemicals
Most paper towels are made from wood pulp and will decompose in a compost pile. The catch is what is on them and how they were made. Paper towels that have wiped up grease, oils, or cleaning products should not go in your bin—they slow decomposition and can introduce substances that harm your finished compost. Unbleached paper towels with only dry debris or water-based spills are safe to add.
The reason paper towels work at all is that they are already broken down wood fiber. Unlike whole leaves or cardboard, they do not need much time to disappear. In an active, warm compost pile, they typically vanish within a few weeks. In a cold or slow pile, they may take longer but will still break down.
Key Takeaways
- Unbleached paper towels with no grease or chemicals can go into your compost bin and will decompose within weeks in an active pile.
- Paper towels that have wiped up oils, butter, meat drippings, or household cleaners should go in the trash instead.
- Bleached white paper towels are safe to compost but decompose slightly slower than unbleached ones.
- Shred or tear paper towels into smaller pieces to speed up breakdown, especially in cooler compost piles.
What makes a paper towel safe to compost
The main rule is straightforward: compost only paper towels that are clean or have only dried food and plant matter on them. A paper towel that dried up spilled juice, wiped a plate, or soaked up water is fine. One that wiped a greasy pan, cleaned up a spill of cooking oil, or was used with furniture polish or window cleaner is not.
Oils and fats coat the paper fibers and slow microbial breakdown. They also create a water-resistant barrier that keeps moisture from reaching the center of the material. In a home compost pile, this can mean a paper towel stays recognizable for months instead of weeks. In a commercial compost facility, which reaches higher temperatures, the same towel might still cause problems because oils can interfere with the finished product's texture and nutrient balance.
Bleach is less of a concern than most people think. Bleached white paper towels are safe to compost. The bleach used in paper manufacturing is broken down during the production process, and what remains is not strong enough to harm your pile. Unbleached towels are slightly better because they have no bleach residue at all, but either type will decompose.
Paper towels versus other paper products in your bin
Paper towels break down faster than cardboard, newspaper, or paper bags because they are already soft and thin. Cardboard and newspaper are denser and take longer to decompose, even though they are also safe to compost. Paper bags fall somewhere in between—they decompose faster than cardboard but slower than paper towels.
If you want to speed up decomposition of any paper product, tear or shred it into smaller pieces. Smaller surface area means microbes can work faster. A shredded paper towel might vanish in two to three weeks, while a whole one might take four to six weeks in the same pile.
Do not compost paper products that have a plastic or wax coating, such as coated paper plates, takeout containers, or wax-lined bags. These do not break down in a home compost pile and will remain as fragments in your finished compost.
How to add paper towels to your compost pile
Tear or crumple the paper towel and add it to your pile along with other materials. Paper towels are considered a "brown" or carbon-rich material, similar to dry leaves or straw. They work best when mixed with "green" materials like food scraps, grass clippings, or plant trimmings. A rough ratio of three parts brown to one part green keeps your pile balanced and decomposing steadily.
If you compost in a bin or tumbler, add paper towels gradually rather than all at once. A handful of shredded towels mixed into a pile of kitchen scraps will disappear without notice. A large clump of whole towels might create a dense pocket that resists breakdown.
In a cold or slow compost pile—one that sits in shade, does not get turned, or receives little moisture—paper towels will still decompose but may take several months. If your pile is warm, moist, and regularly turned or aerated, they will vanish much faster.
When to throw paper towels in the trash instead
Paper towels used to clean up meat, fish, or poultry should go in the trash. Raw or cooked animal products can introduce pathogens into your compost pile and create odor problems. Even if your pile reaches high temperatures, home compost piles are not reliably hot enough to kill all food-borne bacteria, so it is safer to exclude them.
Paper towels used with any household chemical—bleach, disinfectant, window cleaner, furniture polish, or paint thinner—belong in the trash. These substances can persist through the composting process and end up in your finished compost, where they may harm plants or soil microbes.
If a paper towel is wet with grease or oil, throw it away. If you are unsure whether something on the towel will cause problems, the safest choice is the trash. Your compost pile works better when you keep it straightforward and stick to plant-based materials and uncontaminated food scraps.
Alternatives if you want to reduce paper towel waste
If composting paper towels feels like a small gesture, consider using cloth towels or rags for most cleanup tasks. A washable cloth towel lasts for years and eliminates the need for paper towels altogether. You can compost the cloth when it finally wears out, since natural fibers like cotton break down readily.
For tasks where you do need something disposable, look for paper towels made from recycled content or sustainably harvested wood. Some brands are unbleached and packaged with minimal plastic. These still go to compost the same way, but they reduce the environmental cost of production.
If you do not have a compost pile yet, paper towels can be a good reason to start one. They are one of the easiest materials to add, and they help balance a pile that might otherwise be too heavy in food scraps.
Frequently Asked Questions
Can I compost paper towels with peanut butter or jam on them?
Yes, as long as the food is not mixed with oil or grease. Peanut butter contains oil, so paper towels with peanut butter should go in the trash. Jam or other fruit spreads without added oil are fine to compost. If you are unsure whether a food contains oil, err on the side of throwing it away.
What about paper towels used to dry vegetables or fruit?
Those are safe to compost. Paper towels used to pat dry produce, wipe up water spills, or dry your hands are ideal for composting. They have no oils or chemicals and will decompose quickly.
Can I compost paper towels from cleaning up pet accidents?
No. Paper towels contaminated with urine or feces should go in the trash. Home compost piles do not reach temperatures high enough to safely break down pathogens from pet waste. Use a separate trash bin for these items.
Do paper towels slow down my compost pile?
Not if you add them in reasonable amounts. A handful of shredded paper towels mixed into a pile of food scraps and yard waste will decompose without slowing the overall process. Large quantities of whole paper towels might create dense pockets that decompose slowly, so shred them and spread them out.
Can I compost colored or printed paper towels?
Colored paper towels are safe to compost. The dyes used in paper towels are not toxic to soil or plants. Printed designs or patterns are also fine. The only concern is whether anything on the towel—ink, dye, or residue—came from a chemical source, which is rare in consumer paper towels.
