Disposing of compostable bags correctly is essential to make sure they truly benefit the environment. Simply throwing them away without knowing the right steps can prevent proper breakdown and harm the planet.
With compostable bags becoming more common, understanding how to dispose of them properly—whether through home or industrial composting—is key. This guide will help you navigate the process easily and effectively.
By learning these steps, you’re helping reduce plastic waste and support a healthier Earth. Let’s get started on how to dispose of compostable bags the right way!

Understanding Compostable vs. Biodegradable vs. Plastic
Compostable bags are designed to break down under specific conditions into natural elements like water, CO2, and biomass. They typically require a composting environment—either industrial or home-based—to fully degrade.
Biodegradable bags, on the other hand, can break down naturally over time, but the process is less controlled and may still leave behind microplastics.
Plastic bags are made from petroleum-based materials that take hundreds of years to degrade and often pollute ecosystems.
When buying compostable bags, look for certifications such as:
- BPI Certified Compostable (U.S.)
- EN 13432 (Europe)
- TÜV Austria OK Compost
These labels indicate that the product has met stringent standards for compostability.
Compostable Bag Disposal Steps
| Step | Description |
|---|---|
| Step 1: Read the Label | Check if the bag is home or commercial compostable; avoid vague “biodegradable” labels. |
| Step 2: Check Local Options | Confirm if local programs accept compostable bags; if not, trash disposal may be required. |
| Step 3: Avoid Compost Contamination | Do not mix bags with recycling or non-organic waste; empty bags before composting. |
| Step 4: Home Compost Test | Cut and place bags in an active compost pile; check after 30 days for breakdown. |
| Step 5: Use Alternatives | Use reusable containers and minimize compostable bag use when possible. |
Step 1: Read the Label Before You Toss
Before disposing of a compostable bag, it’s important to understand what type you have. Home compostable bags are suitable for backyard compost bins, while commercially compostable bags require the high heat and controlled conditions of industrial facilities.
Always read the label—look for terms like “Home Compostable” or “Commercially Compostable” and check for official certifications or logos. Avoid bags labeled only as “biodegradable,” as this term is often vague and not a guarantee of proper breakdown.
Step 2: Check Your Local Composting Options
Not all municipalities accept compostable bags in their green bins or curbside composting programs. To find out, visit your city or county’s waste management website, use directories like Earth911 or FindAComposter.com, or contact your local recycling center directly. If no commercial composting is available, the bag may have to go in the trash, which defeats its eco-friendly purpose.
Step 3: Avoid Common Mistakes That Contaminate Compost
Even with good intentions, compostable bags can cause contamination if disposed of incorrectly. Common mistakes include tossing them into the recycling bin (they are not recyclable), using commercially compostable bags in a home compost system, or leaving non-compostable contents inside the bag. Always empty the bag and ensure only organic waste is present before composting.
Step 4: Home Composting? Do a Degradation Test
If your bag is labeled “home compostable,” it should break down in a backyard compost pile. However, the speed of degradation can vary. A simple test involves cutting the bag into smaller pieces, placing them in the warm, moist center of an active compost pile, and checking after 30 days. If the material is still intact, your composting conditions may need improvement.
Step 5: Explore Alternatives and Smarter Habits
Even compostable bags have an environmental footprint. Reducing single-use products is always the better choice. You can use reusable containers, jars, or silicone pouches, line your compost bin with newspaper, or go without a liner entirely. Only rely on compostable bags when absolutely necessary to minimize waste.
How to Store Compostable Bags to Keep Them Fresh
To keep compostable bags fresh and effective, store them in a cool, dry place away from heat and humidity. Excess moisture and warmth can cause the bags to start breaking down prematurely, so choosing a pantry or cupboard is best.
Avoid exposing the bags to direct sunlight, as UV rays can degrade the material over time. Keeping them in their original opaque packaging or inside airtight containers will help protect them from light and air.
Make sure to store the bags away from heat sources like ovens, radiators, or other appliances that emit warmth. High temperatures can damage the bags and reduce their lifespan.
Use your bags on a first-in, first-out basis. This means using older bags before newer ones to prevent any from sitting unused too long and potentially deteriorating.
Handle the bags gently and avoid folding or crushing them sharply, as this can compromise their strength and usability.
Finally, if you store the bags for extended periods, check them occasionally for signs of damage such as brittleness or unusual odors to ensure they’re still in good condition.
Best Compostable Bags for Different Needs (Kitchen, Pet Waste, Yard)
Kitchen Compostable Bags
These bags are designed to handle food scraps and moist waste without tearing. They are often thinner for easy disposal but remain durable enough to prevent leaks. Look for ones certified for home composting if you plan to compost at home.
Pet Waste Compostable Bags
Pet waste bags need to be extra strong and leak-resistant to contain liquids and solids safely. They usually have thicker material and secure seals to prevent odors and messes.
Yard Waste Compostable Bags
Yard waste bags are larger and more robust to carry heavier loads like leaves, grass, and small branches. They are built to withstand outdoor conditions and rough handling during collection.
Suggestion:
Selecting the right bag type for each use helps ensure effective composting and minimizes environmental harm.
Common Myths About Compostable Bags Debunked
Compostable bags don’t always break down quickly everywhere—they often need industrial composting conditions like high heat and moisture to fully degrade.
They cannot be placed in regular recycling bins because they contaminate the recycling process.
Not all bags labeled “biodegradable” or “compostable” meet strict standards—look for certifications like BPI or EN 13432.
Using compostable bags improperly, such as throwing them in the trash, can prevent them from breaking down and reduce their environmental benefits.
Compostable bags aren’t a perfect solution; reducing single-use bags and opting for reusable alternatives is still the best way to minimize waste.
FAQ
Q: Can I throw compostable bags in the regular trash?
A: It’s best not to. Compostable bags need specific composting conditions to break down. Throwing them in trash usually sends them to landfill where they won’t decompose properly.
Q: Are compostable bags safe to put in my home compost bin?
A: Some are designed for home composting, but many require industrial facilities. Check the label to confirm if home composting is suitable for your bag.
Q: Can I recycle compostable bags with regular plastics?
A: No. Compostable bags are not recyclable with plastics and can contaminate recycling streams. Always dispose of them through composting channels.
Q: What should I do if my local compost program doesn’t accept compostable bags?
A: Look for drop-off locations or programs nearby. If none exist, consider reducing use or switching to reusable bags until proper composting options are available.
Q: How do I prepare compostable bags before disposal?
A: Empty the bag of any non-organic waste and avoid mixing plastics or other contaminants. Clean, empty bags compost best and break down faster.
Conclusion
Proper disposal of compostable bags ensures they break down as intended and support a circular waste system. Knowing your local composting options and handling bags correctly helps protect the environment.
Keep in mind, not all bags compost the same way, so always check labels and guidelines to avoid contamination and waste.
