Can I Compost Paper Towels?

SAYRU Team Avatar

Short answer: yes, most paper towels are compostable. The nuance is in what they’ve been used for. A paper towel used to wipe up a coffee spill is great compost. A paper towel used to wipe up cleaning bleach is not.

This article covers the categories — what to compost, what to skip, and why. The general rule is straightforward, but the edge cases come up often enough to deserve a clear answer.

What paper towels are made of

Standard paper towels are:
– 90%+ cellulose fiber (from wood pulp)
– Trace bonding agents (typically polyvinyl acetate or starch)
– Small amounts of wet-strength resins (so they don’t fall apart immediately when wet)
– Inks and dyes (in printed sheets)
– Sometimes bleach residues

The cellulose is the same material as cardboard, paper, and most fiber products that compost well. The bonding agents and resins are present in such small quantities that they don’t meaningfully affect compost behavior.

Two-ply paper towels include a small amount of adhesive between the layers. Standard adhesives are not problematic for compost.

When paper towels DO compost

The clear “yes” cases:

Food spills: water, juice, sauce, milk, broth, gravy, etc. These wet the towel but don’t add contaminants. Fully compostable.

Wiping produce: drying washed vegetables and fruits. Fully compostable.

Drying dishes or hands after washing: water plus soap residue is mild. Most dish soaps are biodegradable. Fully compostable.

Wiping countertops with food contact only: water and food residue. Fully compostable.

Wiping greasy hands: small amount of oil from cooking transfers. Compostable in small quantities; large amounts of grease may slow decomposition slightly.

Brown kraft or recycled paper towels: in addition to being compostable, these are often unbleached and have fewer processing chemicals. Premium for compost.

In all these cases, paper towels go in the compost bin or pile alongside other compostable material. They count as “browns” in green/brown ratios for composting.

When paper towels DON’T compost

Cases to skip:

Cleaning chemicals: bleach, ammonia, glass cleaner, disinfectant wipes equivalents, oven cleaner residue. The chemicals on the towel transfer to your compost and ultimately to soil. Skip.

Disinfectant after raw meat contact: even if you used water to wipe, the bacterial load from raw meat is high. If you’re concerned about pathogens, send to trash. Hot composting handles bacteria; cold backyard piles may not.

Heavy grease residue: deep-frying cleanup, fryer grease, salad dressing spills with substantial oil content. The oil itself isn’t problematic in small amounts but in large amounts it slows decomposition and can attract pests.

Strong inks or dye transfers: paper towels printed with strong colors or that have absorbed ink (from printer cartridges, art projects). The ink residues can persist in compost.

Anything from auto-related work: car oil, antifreeze, brake fluid, gasoline. The chemicals are toxic and should go to hazardous waste, not compost or trash.

Cleaning up pet accidents: depends on the cleaning solution used. Plain water — compostable. Enzymatic cleaners — generally compostable in small quantities. Bleach-based — skip.

Heavy paint or finish residue: latex paint dries on the towel; oil-based paint doesn’t. Latex paint dries can compost in small quantities. Oil-based paint or finish should go to hazardous waste.

Wet vs dry paper towels in compost

Wet paper towels actually compost faster than dry ones. The moisture starts the process; the cellulose breaks down quickly. A wet paper towel can fully decompose in 4-8 weeks in a healthy pile.

Dry paper towels take longer to wet up in the pile, then proceed similarly. Total decomposition: 6-10 weeks.

For composters with active piles, this is irrelevant — the towels disappear into the pile regardless of starting moisture. For composters with cold piles or worm bins, slightly wet towels integrate faster.

Volume considerations

A typical household uses 100-200 paper towels per week. That’s substantial paper input to your compost system.

For backyard composting:
– 100-200 paper towels per week = 8-15 ounces of cellulose
– That’s a meaningful brown contribution
– Roughly equivalent to a small handful of dried leaves per week
– Helps balance kitchen scrap (green) input

For worm bins:
– Same volume of paper towels per week
– Provide bedding material as worms consume the older bedding
– Roughly equivalent to a small handful of shredded newspaper per week
– Good for absorbing moisture in the bin

For commercial composting (curbside pickup):
– Paper towels are usually accepted
– Confirm with your hauler if uncertain
– Some haulers exclude paper towels from food-scrap-only bins; others include them

Compostable paper towel brands

Some paper towel brands are marketed specifically as compostable. The relevant features:

  • Unbleached (brown kraft color): no chlorine processing chemicals
  • Recycled content (50-100%): lower carbon footprint
  • BPI certified: industrial composting verified
  • No wet-strength resin: avoids the small amount of synthetic polymer in most paper towels

Brands often associated with compostable claims:
– Seventh Generation Compostable Paper Towels
– Who Gives a Crap (a recycled-paper-focused company)
– Marcal Small Steps
– 100% recycled paper towels from various brands

These are slightly more expensive than standard paper towels ($0.05-0.10 per sheet vs $0.02-0.05) but the difference is small for households that care about the environmental story.

Reusable alternatives

If reducing paper towel use is also a goal, alternatives include:

  • Cotton kitchen rags / shop towels (washed and reused)
  • Microfiber cloths (note: not compostable when discarded)
  • Bamboo “paper towels” (often reusable; check brand specifics)
  • Old t-shirts cut into rags
  • Cloth napkins for food cleanup

For most households, a mix works: cotton rags for daily wipe-downs, paper towels for grease and spillage, compostable disposable when needed.

Reducing total paper towel use is a higher-leverage sustainability change than switching to compostable paper towels. Cotton rags washed and reused for years vs disposable paper towels — the math is favorable for cotton.

A note on commercial paper towel use

For B2B operations (restaurants, food service, manufacturing):
– Paper towels in commercial kitchens often have heavy grease exposure
– Heavy-grease towels are borderline for backyard compost; commercial composting handles them
– For food-contact-only towels, composting works the same as household
– Commercial paper towel volumes are 10-50x household volumes; the compost stream needs to handle it

Restaurants with commercial composting and high paper towel use: the towels are a substantial fraction of the compostable stream. Spec unbleached or recycled paper towels to align with the compostable program.

What about paper napkins?

Similar to paper towels, with one distinction: paper napkins typically don’t have wet-strength resin (they’re designed to be soft, not strong-when-wet).

For composting purposes, paper napkins are essentially identical to paper towels:
– Composts well when used on food
– Compostable when used to wipe water/sauce
– Skip if used with chemicals

What about tissues (Kleenex)?

Used tissues are a separate concern.

Bodily fluid concern: nasal mucus carries respiratory pathogens (cold and flu viruses, bacteria). Most compost piles don’t reach temperatures that reliably kill viruses.

Practical answer: small amounts of household-used tissues in a healthy compost pile are unlikely to spread disease (the pathogens decline naturally). Larger volumes during illness can be a concern.

Better practice during illness: send tissues to trash during cold/flu seasons. Compost them when household is healthy.

What about paper plate residue?

Compostable paper plates can include the paper towels used to wipe them. Both are compostable; the residue can go to compost together.

Compostable plates with food residue and paper-towel wipe go through the same compost stream.

A note on paper towel rolls

The cardboard inner tube of a paper towel roll is fully compostable:
– Cardboard tube: composts in 6-10 weeks
– Some brands include a thin paper wrapper: also compostable
– Plastic wrapping (if applicable): not compostable

For households composting, the rolls and tubes go in compost. Most municipalities accept them in compost bins.

For B2B operations using large industrial-size paper towel rolls: the cardboard tubes (typically 6-12 inches wide) compost normally. The industrial-roll paper itself composts as described above.

How to tell if your specific paper towels are compostable

If you’re uncertain:

  1. Check the brand’s website or packaging: most compostable brands state it clearly
  2. Test in your pile: tear a piece and bury it. Check at 6 weeks. If it’s broken down, the rest of that brand composts.
  3. Default to “yes” for plain water/food use: this is the safe answer for most paper towels.

The brands that aren’t compostable are typically marked as such or are clearly synthetic (e.g., microfiber, premium “shop towel” type products). Most “kitchen paper towels” are fully compostable.

The summary

For most paper towel uses:
– Food spills → compost
– Cleaning with water/soap → compost
– Drying produce → compost
– Greasy hands → compost (small amounts)
– Chemical cleaners → trash
– Heavy grease (fryer cleanup) → trash
– Cleaning after raw meat → trash if concerned, compost if confident

For households trying to reduce paper towel volume:
– Use cotton rags for daily cleanup
– Save paper towels for grease and food spills
– Compost what you use

For commercial operations:
– Standard paper towels are compostable
– Brand selection affects environmental story
– Volume considerations require commercial composting infrastructure

The bigger point: paper towels are the single most common compostable item in households after kitchen scraps. They’re meaningful in volume but invisible in conversation. Getting them into compost (vs landfill) is a small habit with real impact at scale.

A small note: if you’re not sure whether a specific paper towel use should go to compost or trash, default to compost for food-related cleanup. Trash is fine but compost is better when the use case is in the gray zone.

The chemistry of paper towel decomposition

Worth a small detour for curious composters.

Paper towels are processed wood pulp. The cellulose fibers are short (1-2mm) compared to cardboard or natural plant material. This means:

  • Higher surface area per gram
  • Faster microbial colonization
  • Faster decomposition than thicker fiber products

In a compost pile, paper towels become microbially active within hours of being added. Within 1-2 weeks, the visible structure of the towel is mostly gone — what was a recognizable paper towel is now a thinner, more amorphous fiber mass. By 4-6 weeks, the cellulose is fully digested in a hot pile.

The wet-strength resins (small percentage of total mass) take slightly longer to decompose. These are typically polyamine-epichlorohydrin (PAE) resins, which break down in compost conditions but over a slightly longer timeframe (8-12 weeks). The PAE residue is negligible in finished compost.

The inks on printed paper towels (often soy-based or vegetable-based in modern manufacturing) also break down without issues. Older synthetic inks took longer; modern inks decompose with the paper.

Comparison to other paper products in compost

For reference, here’s how paper products compare in compost decomposition rates:

  • Paper towels (uncoated, water-only use): 4-6 weeks in hot pile
  • Office paper (uncoated): 6-10 weeks
  • Newspaper (uncoated): 6-10 weeks
  • Brown paper bags: 4-6 weeks (thicker but porous)
  • Cardboard (corrugated): 8-12 weeks
  • Cardboard (thick): 12-16 weeks
  • Glossy magazines: 6+ months (clay coating slows)
  • Heavily inked printed materials: 8-12 weeks (inks slow slightly)
  • Receipts (thermal): not compostable (thermal coating contains BPA or BPS)

The pattern: thinner, less-processed paper composts faster. Paper towels are at the fastest end of this spectrum.

A small note on bamboo paper towels

Some “paper towels” are made from bamboo fiber rather than wood pulp. These compost similarly to standard paper towels:

  • Bamboo fiber is also cellulose
  • Bamboo paper towels often have less wet-strength resin
  • Bamboo paper towels are often unbleached (better for compost)
  • Decomposition rate: similar to standard paper towels

For compost-focused households, bamboo paper towels are a slight upgrade over standard. Cost is typically 20-30% higher.

The takeaway in three sentences

Most paper towel uses are compostable. The exceptions are clear (chemical cleaning, heavy grease, biohazard contact). For typical household use — water, food, light cleaning — paper towels are a meaningful and welcome addition to your compost stream.

A note on tools

For paper towel users transitioning to a mixed paper/cotton system: keep a small cotton rag basket near the kitchen sink. The rags get used first; paper towels for grease and spills. After a few weeks the habit forms and paper towel use drops naturally to 20-40% of previous volume.

For composters: paper towels are a useful supplement to other browns. Don’t let them be your only brown source (too uniform, lacks structure), but they help fill gaps when leaves and cardboard run low.

For B2B sourcing, see our compostable paper hot cups & lids or compostable cup sleeves & stir sticks catalog.

Verifying claims at the SKU level: ask suppliers for a current Biodegradable Products Institute (BPI) certificate or an OK Compost mark from TÜV Austria, and check that retail-facing copy meets the FTC Green Guides qualifier requirement on environmental claims.
