As pet ownership rises, so does the challenge of managing pet waste responsibly. Dog poop, often seen as a nuisance, raises an important question: Can it be composted? While composting is a celebrated eco-friendly practice, dog feces introduce unique challenges.
This guide explores the science, methods, and safety measures behind composting dog waste, offering pet owners a sustainable alternative to landfills. Let’s dig into the details!
What Is Composting Dog Poop?
Composting dog poop involves breaking down organic waste into nutrient-rich material through controlled decomposition. Unlike regular composting, this process requires special attention to pathogens and temperature. Dog feces contain bacteria like E. coli and parasites, which demand high-heat composting (thermophilic) to neutralize. When done correctly, the result is a safe, soil-like amendment—though it’s best used for non-edible plants.

What’s in Dog Poop?
- Organic Matter:Undigested food, proteins, fats.
- Pathogens: Bacteria (Salmonella), parasites (roundworms), and viruses.
- Nitrogen: High levels, which can imbalance compost if not managed.
–Chemicals: From medications or processed diets.
These components make dog poop riskier than vegetable scraps, necessitating careful handling.
Regular Compost vs. Dog Poop Compost
| Factor | Regular Compost | Dog Poop Compost |
|---|---|---|
| Input Materials | Fruit scraps, leaves | Only dog waste |
| Temperature | 90–130°F | 140°F+ for pathogens |
| End Use | Vegetable gardens | Non-edible plants only |
| Decomposition | 2–6 months | 6–12 months |
Can Dog Poop Go in Compost?
If you’re short on space, can you skip special systems and compost dog poop the old-fashioned way? The answer depends on safety priorities.
Home composting is risky without a dedicated, high-heat setup. Most backyard piles won’t reach temperatures needed to kill pathogens. Certified compostable bags (BPI/OK COMPOST) are safer for curbside programs.
Alternatives to DIY
- Industrial Composting:
- Some cities accept compostable-bagged pet waste
- Requires BPI-certified bags (e.g., ORIZON’s ASTM D6400 compliant)
- In-Ground Digesters:
- Enzyme-activated systems (e.g., Doggie Dooley)
- Bury waste away from water sources
Mythbuster: “Biodegradable” ≠ “Compostable.” Only bags with certifications break down safely in facilities.
Where Can I Find Compostable Poop Bags?
Not all “eco-friendly” bags are equal. Here’s how to spot truly compostable options for guilt-free cleanup.
Look for BPI or OK COMPOST certifications on bags. These guarantee they’ll break down in industrial facilities without microplastic residue. ORIZON’s plant-based PBAT/PLA bags meet global standards for pet waste composting.
Certifications to Trust
- BPI (USA): ASTM D6400 compliant
- OK Compost INDUSTRIAL (EU): EN 13432 certified
- Home Compostable (AS5810): Breaks down in backyard piles
Tip: Avoid “oxo-degradable” bags—they fragment into microplastics.
What Bin Does Dog Poo Go In?
Tossing poop in the wrong bin spreads germs or wastes compost efforts. Follow these rules by disposal method.
Compostable-bagged poop goes in green (organics) bins only if your local facility accepts pet waste. Otherwise, use general waste bins—never recycling, as bags contaminate streams.
Disposal Guidelines by Type
| Bag Type | Accepted Bin | Notes |
|---|---|---|
| Certified Compostable | Green/organics | Verify with local facility |
| Plastic | General waste | Never recycling |
| Unbagged | Trash (may violate laws) | Illegal in parks in AU/NZ/EU |
Always check municipal rules—Sydney accepts compostable bags, while Melbourne restricts pet waste in organics.
Can Dog Poop Be Composted?
Yes, dog poop can be composted, but it must be done carefully and safely.
Because dog poop contains harmful bacteria and parasites, it cannot go into regular compost piles used for food gardens. To safely compost dog poop, you need:
- A hot composting system that reaches 60°C (140°F) or more
- A dedicated compost bin just for pet waste
- Proper materials like sawdust or leaves to mix with the waste
- Time and regular turning for proper breakdown
The finished compost should only be used on non-edible plants like lawns, trees, or flowers.
Does Dog Poop Go in Compost or Garbage?
In most cases, dog poop should go in the garbage, unless:
- You are using a pet-specific composting system
- Your city has a special dog poop composting program
Never add dog poop to regular compost bins or green waste bins unless it is clearly allowed by your local composting rules.
If you’re using compostable dog poop bags, those still need the right composting setup—they don’t break down properly in landfills or in regular trash.
Conclusion
Composting dog poop requires specialized methods to avoid health risks. For hassle-free solutions, use certified compostable bags and check local disposal rules.
FAQ
Is Pet Waste Compostable
Yes, but with major caution. Pet waste (dog/cat/rabbit/etc.) is technically compostable, but it requires very specific conditions to kill pathogens and parasites. Most home compost systems cannot safely handle it.
Is It Safe to Compost Dog Poop?
Only in high-heat (>140°F) systems or industrial facilities. Home piles rarely reach safe temps.
Is Dog Poop Bad for Compost?
Yes, if untreated. It introduces pathogens and acidity that harm plants and soil balance.
How Long Does It Take to Compost Dog Poop?
6–12 months in ideal conditions. Cold weather slows decay significantly.
Does the Composted Product Have an Odor?
Properly processed compost smells earthy. Foul odors mean incomplete breakdown or excess moisture.
