The Backpacker’s Compostable Trash Strategy

Backcountry backpackers operate under Leave No Trace principles — pack out everything you pack in, leave the wilderness as you found it. The principle is clear and broadly accepted in the hiking community. The compostable angle gets complicated in practice. You bought compostable wrappers and packaging because they’re better than plastic. You’re now five miles into the backcountry and the LNT rules say you can’t bury them in the wilderness even though they would, theoretically, decompose. So what do you do?

The honest answer requires some specifics. The principles of Leave No Trace are right; they apply to compostable items the same as plastic items. The wilderness is not a compost facility. But there’s a more nuanced strategy than “treat all waste identically” that reduces what you carry out and aligns with both backcountry ethics and home-side composting practices.

This is the practical waste strategy for multi-day backpacking trips that takes both Leave No Trace and compostable end-of-life seriously.

The Leave No Trace Foundation

Quick refresher on LNT principles relevant to waste:

• Pack out everything you pack in. All wrappers, all containers, all food waste, all hygiene products. The wilderness gets exactly what it had when you arrived.

• Don’t bury food waste. Even biodegradable food waste attracts wildlife, alters local soil chemistry, and creates “garbage trails” where animals learn to forage where humans have been.

• Don’t leave compostable items expecting them to decompose. A banana peel takes years to decompose in many backcountry environments. An orange peel in a desert can persist for decades. “It’s natural” doesn’t mean “it disappears in this specific environment.”

• No human waste shortcuts. Cathole disposal in non-fragile environments at 6+ inches deep, well away from water; pack out in fragile environments (alpine zones, deserts, popular areas).

These principles apply regardless of what materials you bring. Compostable doesn’t equal “leave in the wilderness.” The wilderness isn’t a composting facility; the timescales for compostable items to actually decompose in cold, dry, alpine, or otherwise non-ideal conditions can be years.

What “Compostable” Means in This Context

A backpacker buying compostable items is making a different choice than buying plastic, but not the choice you might think.

The choice is about what happens at home, not in the wilderness. Compostable wrappers, BPI-certified packaging, paper bags — these matter because when you pack them out and dispose of them at home (or at trailhead trash if it’s headed to landfill), the lifecycle impact is lower than petroleum plastic. The compostable items still go to landfill or compost depending on infrastructure when you get home; they don’t go in the wilderness regardless.

So the strategy: choose compostable items for what you bring, knowing they’re “compostable when you get home” rather than “compostable in the field.”

What to Pack: Compostable-Forward Choices

A practical compostable-conscious packing list:

Food packaging:
– Foods in paper or compostable wrappers rather than plastic when available
– Bulk bin staples in your own reusable containers (silicone bags, fabric pouches, glass jars for short trips)
– Bars and snacks in paper-based wrappers (Lärabar, RXBar in older packaging, some Cliff bar lines)
– Avoid: foil-lined wrappers (most “biodegradable” foil-paper backpacking food packaging actually has aluminum that doesn’t decompose)

Cooking supplies:
– Reusable utensils (titanium spork, bamboo spork, compact stainless flatware)
– Fabric or silicone bowls instead of disposable
– Avoid: single-use plastic cutlery and bowls

Hygiene:
– Bamboo toothbrush and toothpaste tablets (in compostable packaging) rather than plastic toothbrushes and tubes
– Compostable wet wipes for face and hand cleaning (still pack out the used ones — see below)
– Cotton or wool bandanas rather than disposable hand towels

Trash storage:
– A dedicated trash bag for the trip (a freezer-grade Ziploc holds substantial trash for 2-4 days)
– Some hikers use specifically-designed odor-resistant trash bags for longer trips
– Compostable trash bags are an option but they degrade in moisture; a regular plastic Ziploc is often more practical

The point isn’t that every item is compostable — it’s that the items you can swap to compostable get the lifecycle benefit when you eventually dispose of them at home.

Food Waste Specifically

Food waste is where backcountry strategy gets specific.

Fruit peels (banana, orange, apple core): Pack out. Don’t bury. They take years to decompose in cool or dry environments and they attract wildlife.

Nut shells, seeds, fruit pits: Pack out. Same logic. Plus some (like apricot pits) take longer than the trees take to grow.

Cooking wastewater: Strain solids out, pack solids out. Strained water (mostly water with some food traces) can be poured on the ground 200+ feet from water sources, in non-fragile environments. Don’t dump cooking water near streams.

Grease and oil: Pack out. Don’t pour on the ground or in streams.

Crumbs and small particles: What you can sweep up with a paper towel goes out with the trash. What’s truly negligible (a few crumbs) is acceptable but minimize the volume.

Leftover meals: If you cooked too much, you eat the rest at the next meal or pack it out. Don’t dump pasta or rice into the wilderness.

The dedicated trash bag handles all of this. A freezer-grade Ziploc is reasonably odor-resistant for a 2-4 day trip; longer trips benefit from purpose-built containers.

Used Compostable Wipes

Wet wipes (compostable or otherwise) get used for face and hand cleaning, occasionally bathroom cleanup. The disposal:

Compostable wipes: Pack out. Don’t bury. Even compostable wipes don’t break down quickly in many backcountry environments. They join the trash bag.

Diaper-related wipes: Pack out. Always. The combination of wipe and contents is not appropriate for cathole disposal regardless of wipe material. Doubly-bagged in waste bag, packed out.

At home, separate the compostables: When you get home, the compostable wipes (clean ones, used for face/hand cleaning) can go to compost if you have access. Wipes used for bathroom contents go to trash regardless of material.

The honest answer for many backpackers: it’s all going to landfill via the campground trash anyway, so the wipe material matters less in the field than at home. Choose compostable for the home-side benefit; treat them all as pack-out trash in the field.

Human Waste

Briefly worth covering because compostable wipes and toilet paper come up.

Standard cathole disposal: 6-8 inch deep hole, 200+ feet from water, trail, and camp. Cover when done. Acceptable in non-fragile environments where soil and biological activity will process the waste over time.

Toilet paper: In many areas, you can bury TP in the cathole. Plain unbleached TP biodegrades reasonably; the bleach in white TP is mostly oxygen-bleach now (not chlorine) so the impact is similar.

Compostable / wet wipes: Don’t bury. Even compostable wipes don’t break down at cathole speeds. Pack out.

Pack-out areas: In sensitive ecosystems (alpine, desert, heavily-used popular areas, glacier travel), pack out all human waste using WAG bags or similar. The destination is appropriate-handling at trailhead or home.

Compostable wag-bag products exist but are still single-use in the field — you pack them out and dispose at home. They’re an upgrade over plastic wag bags but not a “compost in the field” solution.

The general principle: in the field, treat everything as pack-out trash. At home, separate the compostables from the actual trash and dispose of each appropriately.

Trip-End Trash Sorting

When you get back to the trailhead or home, the work isn’t done.

At trailhead: If trailhead has trash service, that service typically goes to landfill. Any compostable items you packed out end up in landfill via this route — the lifecycle benefit was the choice of compostable over plastic, not field-side composting.

At home: This is where compostable choice pays off. Sort the trash bag:

• Food scraps (peels, cores, etc.) → home compost or municipal organics if available
• Compostable wrappers and packaging → same destination if your local infrastructure accepts them
• Compostable wipes (clean ones) → home compost
• Petroleum plastic items, foil-lined wrappers, anything not compostable → trash
• Items contaminated with bathroom contents → trash regardless of material

The 30 minutes of sorting at home turns “pack out everything” into “everything that can be composted, gets composted; everything else goes to trash.” The compostable items finally find their way to the appropriate destination.

What Compostable Doesn’t Solve

A few items where the compostable choice doesn’t help much in backpacking context:

Backpacker-specific freeze-dried meals. Most have foil-lined pouches that don’t compost regardless of what the brand claims. Look for newer brands using paper-only packaging if you care about this; otherwise treat as standard plastic packaging.

Energy bars with foil interior. Most “wrapper” packaging on bars has aluminum interior layer for moisture barrier. The wrapper is not actually compostable. Some specific products (newer Lärabar runs, certain RXBar variants) use paper-only packaging.

Tea bags in field. Some tea bags have nylon mesh that doesn’t compost. Pack out tea bags regardless of brand; sort at home.

Ziploc bags as trash storage. The trash bag itself is plastic, not compostable. Reusable for multiple trips.

For these items, the choice is between buying the compostable version (where available) at premium price or accepting the conventional version. Both choices are defensible; the “compostable in the field” claim doesn’t apply either way.

What This Adds Up To

A 4-day backpacking trip for one person typically generates:

• 30-50 food wrappers
• 5-15 wet wipes
• A pile of crumbs and small food residue
• Some toilet paper (potentially buried; potentially packed out)
• Used cooking wastewater (handled via gray water disposal)
• Used water filter cartridges, broken gear, occasional medical waste

Total carry-out volume: usually fits in a gallon Ziploc with room to spare. Total weight: usually under a pound at trip end.

If half of this is compostable items packaged in compostable wrappers, the home-side composting handles roughly half. The other half goes to landfill. The split between landfill and composting at home is the “save” from making compostable choices in the field.

For trips at population scale (thousands of backpackers per year per popular trail), the cumulative effect of compostable choices is meaningful. For individual trips, the personal benefit is modest but the principle (matching what you buy to what you can dispose of properly at home) is sound.

The Pre-Trip and Post-Trip Routine

The compostable-conscious backpacker’s routine bookends the trip itself:

Pre-trip: Choose compostable packaging where available. Repackage bulk food into reusable containers. Pack a dedicated trash bag. Skip items with foil-lined or plastic-only packaging where alternatives exist.

During trip: Pack out all waste. No exceptions for “compostable” items. Treat the trash bag as a single category until you get home.

Post-trip: Sort the trash bag. Compostables to compost; non-compostables to trash. Wash and reuse the trash bag for the next trip.

The pre-trip and post-trip work takes 30-60 minutes total. The during-trip discipline is the same as standard LNT. The compostable choices show up at the home-side disposal step.

The Honest Backpacker’s Truth

Backpacking generates waste. The wilderness ethics require packing it out. The compostable angle reduces the lifecycle impact of what you pack in but doesn’t change the field-side disposal rules.

The framing that helps: “I’m choosing compostable because at home, compostable means something. In the field, it’s just trash that needs to come back with me.” That framing avoids the temptation to treat compostable items as field-disposable, while still capturing the lifecycle benefit when you actually dispose of them at home.

For most weekend warrior backpackers and serious wilderness travelers, this is the realistic answer. The wilderness is not a composting facility; your home (or your municipality’s organics program) is. Match the choice to that reality, and the compostable choice produces real environmental benefit even though the field-side handling looks identical to packing out plastic. The benefit shows up at the moment your compostable wrapper goes into the home compost bin instead of the trash, not while you’re hiking.

Background on the underlying standards: ASTM D6400 defines the U.S. industrial-compost performance bar, EN 13432 harmonises the EU equivalent, and the FTC Green Guides govern how “compostable” can be marketed on packaging in the United States.
