Toilet Paper Decomposition Time Explained

Quick answer

• Toilet paper breaks down much faster than most people think, especially in the right conditions.
• Expect it to decompose in anywhere from a few days to a few weeks in typical camping environments.
• Factors like moisture, temperature, and microbial activity are key.
• Avoid burying it too deep or packing it down; this slows things down considerably.
• Pack it out if you’re unsure or in sensitive areas. It’s the safest bet.
• Different types of TP break down at different rates.

For the fastest decomposition, consider using a high-quality biodegradable toilet paper designed for outdoor use.

What to check first (do this before you drive out)

Before you even think about hitting the trail, get a few things squared away. This isn’t rocket science, but it’s good sense.

• Land manager / legality: Who’s in charge here? Is it US Forest Service, BLM, a state park? They set the rules. Sometimes there are specific disposal requirements for human waste and TP. You don’t want to be that person who gets a ticket.
• Access/road conditions: Can your rig even get there? Is it a smooth dirt road or are you crawling over rocks and through mud? Knowing this avoids a tow truck call. I learned that lesson the hard way once.
• Fire restrictions + weather + wind: This is crucial. Dry conditions mean fire danger is high. Check the local fire restrictions religiously. Also, look at the forecast. High winds can make campfires a no-go and affect how things dry out.
• Water plan + waste plan (Leave No Trace): Where are you getting water? How are you treating it? And what’s your plan for waste, including TP? LNT principles are your guide. Generally, pack it out, especially in high-use or sensitive areas.
• Safety (wildlife, distance to help, comms): What critters live here? Are bears a thing? Know your surroundings. How far are you from the nearest ranger station or town? Do you have cell service? A satellite communicator is a good idea in remote spots.

Step-by-step (field workflow)

Alright, you’re at camp. Here’s how to handle your business and your TP like a pro.

1. Find a suitable spot: Locate a place at least 200 feet from water sources, trails, and campsites.

• Good looks like: A discreet area that’s not obvious to others and won’t be easily washed out.
• Common mistake: Setting up too close to a creek. You don’t want to contaminate water. Dig your cathole away from it.

2. Dig a cathole: Use a small trowel to dig a hole 6–8 inches deep.

• Good looks like: A hole that’s deep enough to cover your waste completely and obscure it from view.
• Common mistake: Digging too shallow. This leaves waste exposed, which is gross and unhygienic.

3. Do your business: Use the cathole as intended.

• Good looks like: Using the hole effectively for solid waste.
• Common mistake: Missing the hole. Clean it up immediately with biodegradable soap and water if possible, or pack out soiled TP.

4. Use toilet paper sparingly: Use only what you need.

• Good looks like: A few squares to get the job done.
• Common mistake: Using a whole wad. It’s unnecessary and takes longer to break down.

5. Tear TP into smaller pieces: If you’re going to bury it, this helps.

• Good looks like: Pieces about the size of a playing card.
• Common mistake: Leaving large sheets. They take longer to decompose and can be unsightly.

6. Bury the TP (if allowed and appropriate): Cover the TP with dirt and soil.

• Good looks like: The TP is completely covered and mixed with the soil.
• Common mistake: Just scraping dirt over it. Pack the soil down a bit to encourage contact with microbes.

7. Cover the cathole: Fill the hole completely with the original soil.

• Good looks like: The ground looks as natural as possible, like you were never there.
• Common mistake: Leaving a depression or mound. This shows exactly where you dug.

8. Disguise the area: Scatter leaves or natural debris over the spot.

• Good looks like: The area blends in with its surroundings.
• Common mistake: Leaving it bare. It’s a dead giveaway of human activity.

9. Pack out TP (if required or preferred): Use a sealable bag (like a Ziploc) to carry out used toilet paper.

• Good looks like: All waste, including TP, is contained and removed from the site.
• Common mistake: Leaving it behind in the cathole, even if buried. This is especially bad in sensitive ecosystems or where decomposition is slow.

10. Wash your hands: Use biodegradable soap and water or hand sanitizer.

• Good looks like: Clean hands free of contaminants.
• Common mistake: Not washing hands. This spreads germs.

When packing out is necessary, using dedicated pack-out waste bags makes the process clean and discreet.

A sturdy camping trowel is essential for digging a proper cathole, ensuring your waste is buried effectively.

Common mistakes (and what happens if you ignore them)

Mistake	What it causes	Fix
Burying TP too deep	Slows decomposition significantly; can remain intact for a long time.	Dig your cathole to the recommended depth (6-8 inches). Ensure TP is mixed with soil, not just buried under a layer.
Packing TP down tightly in a cathole	Reduces air and microbial exposure, hindering decomposition.	Gently mix TP with the soil. Avoid compacting the soil directly over the TP.
Using non-biodegradable TP	Takes much longer to break down, can clog systems, or persist in nature.	Stick to single-ply, unscented toilet paper designed for camping or septic systems. Avoid anything with lotions or extra plies.
Leaving TP exposed above ground	Unsightly, attracts pests, can be spread by wind or animals.	Always bury TP properly or pack it out. If it accidentally gets exposed, re-bury it or pick it up.
Not checking fire restrictions	Illegal fires, potential for devastating wildfires.	Always check official sources for current fire restrictions before you go and while you’re out. Heed all warnings.
Using TP near water sources	Contaminates water, harms aquatic life, violates LNT principles.	Maintain a minimum 200-foot buffer from all water bodies for all waste disposal, including TP.
Not packing out TP in high-use or sensitive areas	Creates “toilet paper trees,” pollutes the environment, degrades the experience.	When in doubt, pack it out. Use a dedicated bag for used TP. This is standard practice in many national parks and wilderness areas.
Using excessive amounts of TP	Takes longer to break down, more waste to manage.	Be mindful of how much you use. Often, a few squares are sufficient. Consider alternatives like a bidet bottle if you’re concerned about cleanliness and TP use.
Not properly disguising catholes	Leaves visible signs of human impact, makes the area look messy.	After filling the cathole, scatter leaves, pine needles, or other natural debris to make the spot blend in.
Assuming TP decomposes instantly	Leads to improper disposal and environmental impact.	Understand that decomposition takes time and depends on conditions. Always plan for the possibility that it won’t break down immediately.

Decision rules (simple if/then)

Here’s how to make the call on TP disposal.

• If the area is a designated campground with toilets, then use the provided facilities because they are designed for waste management.
• If you are in a wilderness area or backcountry, then check the specific regulations for that area regarding waste disposal because rules can vary significantly.
• If fire restrictions are in place, then do not bury TP in a cathole where you might also have a fire; pack it out instead because burning waste can be dangerous and illegal.
• If the ground is very wet or saturated, then consider packing out TP because decomposition will be very slow, and it might not break down at all.
• If the ground is very dry and hard, then packing out TP might be easier than digging a proper cathole and ensuring the TP decomposes, because digging can be tough.
• If you are using a portable toilet system, then follow the manufacturer’s instructions for TP disposal because these systems have specific requirements.
• If you are unsure about local decomposition rates or regulations, then err on the side of caution and pack out your toilet paper because it’s the most responsible choice.
• If you’re using multi-ply or scented TP, then pack it out because these types break down much slower than single-ply, unscented varieties.
• If you’re in an area with very limited soil or microbial activity (like desert or alpine environments), then pack out your TP because decomposition will be extremely slow.
• If you have any doubts about leaving TP behind, then pack it out because it’s always better to be safe than sorry and leave no trace.
• If you are camping with a group, then establish a clear system for waste management beforehand to ensure everyone knows the plan for TP.

FAQ

How long does it take for toilet paper to decompose in a campfire?

It burns. That’s the point. Just make sure it’s fully extinguished. Don’t leave smoldering embers.

Can I use baby wipes instead of toilet paper?

No. Baby wipes are generally not biodegradable and take a very long time to break down. Pack them out. Always.

What if I can’t dig a cathole because the ground is too rocky?

If digging is impossible, you must pack out all solid waste and toilet paper. Use a sealable bag.

Does freezing weather affect toilet paper decomposition?

Yes. Freezing temperatures can significantly slow down or halt microbial activity, pausing decomposition until it thaws.

Is there a difference between regular TP and camping TP?

Yes. Camping or septic-safe TP is designed to break down much faster in water and with less agitation than standard household TP.

What happens if I just leave TP in the woods?

It’s unsightly, can be spread by animals, and doesn’t decompose quickly enough to avoid leaving a trace. It’s also disrespectful to the environment and other users.

How do I properly dispose of TP in a vault toilet?

Most vault toilets are designed to handle toilet paper. Just toss it in. Check for any specific signs posted at the toilet facility.
