Meanwhile, the UNNI 2.6 Gallon Compostable Bags are ideal for small kitchens or compost bins due to their compact size and extra thickness. These options reflect common tradeoffs: larger, thicker bags tend to cost more and may be overkill for some uses, while smaller bags may lack the strength for heavier waste. Continue reading to see how each product compares and find the best fit for your eco-conscious needs.

Key Takeaways

• Thicker bags generally offer better durability but tend to be more expensive per bag.
• Size variety is critical—choose smaller bags for compost bins and larger ones for kitchen trash to avoid waste.
• Certifications like ASTM D6400 or EN13432 ensure true compostability, not just biodegradability.
• Bulk packs provide better value but may include sizes or qualities that don’t match specific needs.
• Drawstring handles improve usability but can sometimes compromise bag integrity if not well-made.

More Details on Our Top Picks

1. 13 Gallon Compostable Trash Bags, 50 Count, Eco-Friendly Biodegradable Garbage Bags with Drawstring

   

   Best Overall for Versatility and Certification

   View on Amazon

   This option stands out for combining high environmental standards with practical features. Made from plant starch, these bags are certified by BPI, OK COMPOST, and Seedling, ensuring reliable compostability—an advantage over alternatives like UNNI 2.6 Gallon Bags, which lack multiple certifications. The thickened design reduces leaks and tears, making them suitable for diverse waste streams, from kitchen scraps to outdoor yard waste. However, their size limits their use to bins under 15.3 inches in diameter, unlike larger-capacity bags that can handle more waste in one go. Compared with thinner options, these offer better durability, but the tradeoff is a slightly higher price and limited capacity. Overall, they are best for environmentally conscious households seeking certified compostable bags that fit standard kitchen bins without sacrificing durability.

   Pros:

   • Certified by multiple reputable standards ensuring true compostability
   • Thickened design prevents leaks and tears during use
   • Versatile for indoor and outdoor waste disposal
   • Eco-friendly and biodegradable, reducing plastic waste

   Cons:

   • Limited to bins with a diameter less than 15.3 inches
   • Capacity restricted to 13 gallons, not suitable for larger bins

   Best for: Eco-minded homeowners who want certified compostable bags for various waste types and value durability.

   Not ideal for: Large households with bigger bins or those needing bags for heavy, sharp waste beyond 13 gallons, as the size and strength may be limiting.

   • Size:24 inches x 30 inches
   • Capacity:13 gallons
   • Count:50 bags
   • Material:Plant starch (corn) material
   • Certifications:BPI, OK COMPOST, Seedling
   Our verdict

   “This bag set offers a reliable, certified compostable choice for those seeking versatile, eco-friendly waste disposal in standard-sized bins.”

2. BPI Certified Compostable Trash Bags 13 Gallon, 30 Count

   

   Best for Heavy-Duty Leak Resistance

   View on Amazon

   Compared with the first option, this set emphasizes extra thickness—being three times thicker than regular compostable bags—which makes it better suited for messier waste like food scraps or garden debris. The 0.91 mil thickness enhances tear and leak resistance, a key advantage over thinner bags like the UNNI 2.6 Gallon Bags, which may rip under heavy loads. These bags are also certified for rapid breakdown in home or industrial composting within 90-180 days, making them a strong eco-conscious choice. However, their larger size makes them incompatible with small or compact bins, and proper storage is required to maintain their integrity over time. This choice makes the most sense for users prioritizing durability and leak prevention over capacity or size flexibility.

   Pros:

   • Three times thicker than standard compostable bags for added durability
   • Leak and tear resistant, suitable for messy waste
   • Certified to break down efficiently within 90-180 days
   • Safe for indoor use around kids and pets

   Cons:

   • Requires careful storage to prevent degradation over time
   • Not suitable for waste exceeding 10 lbs or sharp objects

   Best for: Families or individuals with messy waste who need durable, leak-resistant bags for standard 13-gallon bins.

   Not ideal for: People with smaller countertop or compost bins, as the size and thickness may be excessive and less practical.

   • Size:23.6 in x 31.5 in
   • Capacity:13 gallons
   • Thickness:0.91 mils
   • Material:Plant-based (corn starch and biodegradable resin)
   • Count:30 bags
   Our verdict

   “This bag set excels for those needing heavy-duty, leak-resistant compostable bags in standard kitchen sizes, with some storage precautions.”

3. Compostable Trash Bags, 13-15 Gallon Tall Kitchen Garbage Bags, Heavy Duty Unscented, 60 Count

   

   Best for Heavy Household Waste and Odor Control

   View on Amazon

   This pick makes the most sense for households handling a variety of waste, including food, diapers, or litter, thanks to its strong, durable design made from renewable cornstarch blends. Its capacity of 13-15 gallons offers flexibility for larger bins, outperforming smaller capacity options like UNNI 2.6 Gallon Bags. The odorless feature makes it suitable for sensitive environments, unlike some thinner, scented bags that can be overpowering. The main tradeoff is the higher cost compared to conventional plastic bags, and industrial composting facilities are often required for full breakdown, which might limit some users. Compared to the first product, this bag emphasizes strength and odor control, fitting well into busy household waste routines.

   Pros:

   • Strong and durable to prevent tearing from heavy or sharp waste
   • Odorless and unscented, suitable for sensitive environments
   • Fits 13-15 gallon cans with ease
   • Made from renewable, eco-friendly materials

   Cons:

   • Higher price point than conventional plastic bags
   • Full breakdown requires industrial composting facilities

   Best for: Households with mixed waste streams seeking strong, odorless bags for 13-15 gallon bins.

   Not ideal for: Users with smaller bins or those who want lower-cost options for infrequent light waste, as it is more expensive and designed for heavier use.

   • Capacity:13-15 gallons
   • Material:Plant-based cornstarch blend
   • Thickness:1.18 mils
   • Count:60
   Our verdict

   “This bag set is ideal for eco-conscious households needing durable, odorless, large-capacity compostable bags for everyday household waste.”

4. ANECO 100% Compostable Waste Bags 2.6 Gallon (110 Count) with 10 Bonus Bags

   

   Best for Small-Scale, Everyday Countertop Use

   View on Amazon

   This option makes the most sense for those with small countertop or bathroom bins, offering a high volume of 110 bags at a reasonable price. Made from plant-based materials like corn starch, these bags are fully compostable and meet ASTM standards, but their small capacity limits their use to light waste like food scraps or small litter bins. The extra thickness at 0.71 mil improves durability over thinner options, though they may still be less resistant to heavy or sharp waste compared to larger, thicker bags. Compared to the UNNI 2.6 Gallon Bags, these include bonus bags at no extra cost, making them a cost-effective choice for daily composting. However, their decomposition time of 6-12 months might not suit urgent waste disposal needs.

   Pros:

   • Made from 100% plant-based, certified compostable materials
   • Extra thick for durability in small waste applications
   • High quantity with 110 bags and bonus extras
   • Fully compliant with composting standards

   Cons:

   • Limited to 2.6-gallon waste, unsuitable for larger bins
   • Decomposition takes 6-12 months, not immediate

   Best for: Individuals or small families using countertop compost bins who prioritize quantity and full compostability.

   Not ideal for: Users with larger or heavy waste needs, as the capacity and durability may fall short for bulkier trash.

   • Capacity:2.6 gallons
   • Count:110 (including 10 bonus)
   • Material:Plant-based, corn starch
   • Standards:ASTM D6400, OK Compost
   Our verdict

   “Perfect for small, daily countertop composting with an emphasis on quantity and full compostability, but not for larger waste volumes.”

   → See it on Amazon →

5. UNNI 2.6 Gallon Compostable Bags, 100 Count, Extra Thick 0.71 Mil

   

   Best Budget Choice for Small Bins

   View on Amazon

   This product is tailored for budget-conscious consumers needing small, durable compostable bags for daily use. Its 2.6-gallon capacity and extra thickness of 0.71 mil make it suitable for food scraps and small waste bins, outperforming thinner, less durable options. However, compared with the first product, it lacks multiple certifications, which might concern buyers seeking verified standards. Its smaller size and lower cost make it ideal for those who want a large number of cheap, reliable bags for frequent use, but industrial composting facilities are often necessary for full breakdown. The main tradeoff involves balancing the lower price with the potential variability in environmental certifications and decomposition times.

   Pros:

   • Extra thick at 0.71 mil for durability
   • High quantity at 100 bags per roll
   • Made from plant-based, compostable materials
   • Cost-effective for frequent small waste disposal

   Cons:

   • Fewer certifications compared to premium options
   • Limited to small waste bin sizes, not suitable for larger trash

   Best for: Small household or office users needing affordable, durable compostable bags for countertop or small waste bins.

   Not ideal for: Larger households or those with heavy, sharp waste, as the capacity and durability may not meet their needs.

   • Capacity:2.6 gallons
   • Unit Count:100
   • Thickness:0.71 mil
   • Material:Compostable plant-based
   Our verdict

   “This set offers affordable, durable compostable bags for small waste bins, ideal for budget-conscious users.”

6. Simply Bio 13 Gallon Compostable Trash Bags Liners Drawstring, Heavy Duty Extra Thick 1 Mil, 30 Bags

   

   Best Heavy-Duty Compostable Bag for Durability

   View on Amazon

   This option stands out for its thick 1 mil plant-based material that offers superior durability compared to thinner bags like the UNNI 3 Gallon Compost Bags. It is ideal for households generating heavier waste, thanks to its leak-resistant, extra-strong construction. While it is more expensive than standard compostable bags, its sturdy build makes it suitable for frequent, demanding use. The drawstring adds convenience, but the higher cost may deter budget-conscious buyers who only need occasional use. Compared with lighter options like the Compostic Tall Kitchen Bags, this bag’s robustness comes at a premium, but it excels in handling tougher waste without tearing.

   Pros:

   • Heavy-duty 1 mil thickness for tough waste
   • Leak-resistant and durable for reliable use
   • Includes convenient drawstring closure

   Cons:

   • Higher price point compared to thinner or simpler bags
   • Limited to compostable waste, not general trash

   Best for: Homeowners or small businesses needing a reliable, heavy-duty compostable bag for kitchen or commercial waste

   Not ideal for: Casual users who want budget-friendly, everyday compost bags for light waste and are willing to accept less durability

   • Capacity:13 gallons
   • Material:PLA and PBAT
   • Thickness:1 mil
   • Size:23.7 x 29.4 inches
   • Bags per roll:30
   Our verdict

   “This bag is best suited for users prioritizing strength and durability over cost, especially for demanding composting needs.”

7. Compostable Trash Bags – 13 Gallon, 80 Count, Unscented, Green

   

   Best for Versatility and Home Use

   View on Amazon

   Compared with the Simply Bio bags, this set offers a slightly larger quantity at a similar price, making it a good choice for households needing frequent replacements. Its octagonal bottom enhances strength and leak-proof performance, making it suitable for kitchen, bathroom, or small office waste bins. The bags are certified to meet ASTM D6400 and EN 13432 standards, ensuring easy composting where facilities are available. However, their size limits them to smaller bins—larger trash cans may require bigger bags or multiple bags, unlike the heavier-duty options. This model’s eco-certifications and reliable performance make it ideal for environmentally conscious users who manage small to medium waste streams.

   Pros:

   • Eco-friendly, certified compostable material
   • Leak-proof with reinforced octagonal bottom
   • Suitable for various small waste bins and multiple settings
   • Odorless and safe for home composting

   Cons:

   • Limited to small bin sizes, not suitable for large trash cans
   • May be more expensive than conventional plastic bags

   Best for: Home users or offices with small waste bins who want a reliable, eco-friendly option

   Not ideal for: People with large trash cans or heavy, bulky waste who need a more robust or larger capacity bag

   • Size:24.8 x 31.4 inches
   • Capacity:13 gallons
   • Material:Plant starch (PSM)
   • Count:80
   • Certification:ASTM D6400, EN 13432
   Our verdict

   “This bag works well for small waste streams in eco-conscious environments but isn’t designed for large or heavy waste loads.”

   → See it on Amazon →

8. UNNI 3 Gallon Compost Bags, 100 Count, Extra Thick 0.71 Mil, Compostable Kitchen Bin Liners

   

   Best for Small Kitchen Waste and Daily Use

   View on Amazon

   This pick makes the most sense for small-scale composting in kitchens, especially when compared to larger, heavier-duty bags like the Simply Bio 13 Gallon option. Its 0.71 mil thickness balances durability with ease of use, and the compact size fits perfectly into small bins. While not suited for large or heavy waste, its certified compostability and thick design make it ideal for daily food scrap collection. The limited capacity means it’s less versatile for larger households or commercial settings, and it has a shorter recommended use window of 9 months. Overall, this bag’s small size and durability are tailored for everyday kitchen use where space and convenience matter most.

   Pros:

   • Extra thick 0.71 mil for durability
   • Fits small kitchen compost bins perfectly
   • Certified compostable and environmentally friendly

   Cons:

   • Use within 9 months for optimal performance
   • Limited capacity unsuitable for larger households

   Best for: Individuals or small families needing daily compost collection in small kitchen bins

   Not ideal for: Users with large or heavy waste streams or those needing long-term storage of waste

   • Capacity:3 gallons / 11.35 liters
   • Quantity:100 bags
   • Thickness:0.71 mil
   • Dimensions:16.9 x 17.7 inches
   • Certifications:BPI, CMA, OK compost HOME
   Our verdict

   “This bag is ideal for daily food scrap collection in small kitchens but isn’t suitable for larger or long-term composting needs.”

   → See it on Amazon →

9. Compostic Compostable Trash Bags, 13 Gallon Tall Kitchen, 50 Count

   

   Best for Fast Decomposition and Household Waste

   View on Amazon

   Compared to other 13-gallon bags like UNNI or the Simply Bio, the Compostic bags are designed for quicker breakdown, decomposing fully within 12-24 weeks in home compost settings. Their extra tear-resistant, tall design makes them particularly suited for tall kitchen bins, providing a tidy fit and reliable strength. The biodegradable packaging and soy-based inks add to their eco credentials. However, they may require a home compost setup for full decomposition—without such facilities, they risk behaving like conventional waste. This makes them a smart choice for eco-conscious households committed to timely composting, but less practical where composting infrastructure is absent.

   Pros:

   • Eco-friendly, fully compostable within weeks
   • Extra strong and tear-resistant for household waste
   • Designed for tall kitchen bins

   Cons:

   • Requires home composting setup for full breakdown
   • Limited to 13-gallon bins

   Best for: Eco-minded households with access to home composting setups seeking rapid decomposition

   Not ideal for: Users without composting facilities or those needing long-term storage of waste

   • Capacity:13 gallons
   • Count:50
   • Dimensions:23 x 28 inches
   • Material:Plant-based biopolymers
   • Certifications:DIN CERTCO home compostable
   • Tear Resistance:Extra strong
   Our verdict

   “This bag is best for households committed to quick composting, provided they have the right setup for full decomposition.”

10. UNNI 13 Gallon Compostable Bags, 50 Count, Extra Thick 0.9 Mil

    

    Best Reinforced Durability for Large Waste Loads

    View on Amazon

    Compared with the Simply Bio 1 mil bags, this UNNI model offers a thicker 0.9 mil construction, making it better suited for handling heavier, more demanding waste. Reinforced for added strength, these bags are designed to resist tearing during typical household chores, especially when managing tall kitchen waste or mixed refuse. Their higher durability comes with a slightly higher price and the same size constraints as other 13-gallon options—limiting their use to smaller or moderate waste streams. They are certified compostable by multiple organizations, making them a sustainable choice. This bag is ideal for those who need extra toughness but are willing to pay a premium for it.

    Pros:

    • Extra thick 0.9 mil for enhanced durability
    • Reinforced to resist tearing
    • Certified compostable by reputable organizations

    Cons:

    • More expensive than thinner alternatives
    • Limited to 13-gallon capacity, not for large-scale waste

    Best for: Households that generate heavier waste or want an extra durable compostable bag for kitchen or bathroom use

    Not ideal for: Users with very large waste volumes or who prioritize low-cost options without reinforced features

    • Capacity:13 gallons / 49.2 liters
    • Number of Bags:50
    • Thickness:0.9 mil
    • Dimensions:23.75 x 31.49 inches
    • Certification:BPI, CMA, OK compost HOME
    Our verdict

    “This bag is ideal for users needing reinforced strength for demanding waste but at a higher cost compared to standard options.”

11. SUPERBIO 1.6 Gallon Handle Tie Compostable Food Scrap Bags, 50 Count

    

    Best for Small-Scale Food Scraps and Ease of Use

    View on Amazon
    This option stands out for its tailored size and added convenience features like handle ties, making it ideal for small countertop compost bins. Compared with the 1.6-gallon bags from product B0BVHZP857, SUPERBIO’s reinforced bottoms and tear-proof design provide greater durability under heavier loads, but its shelf life of about 1 year means it requires timely usage. The handle ties simplify removal and transfer, reducing mess, yet the packaging variability might affect ease of ordering. Designed specifically for food scraps, its size and reinforced features make it a practical choice for those who compost frequently in small spaces. However, it may not work well with larger or commercial compost setups, which demand bigger or more robust bags.
    Pros:

    • Tailored for small kitchen compost bins with handle ties for easy removal
    • Reinforced bottoms and tear-proof design enhance durability
    • Certified compostable with eco-friendly credentials

    Cons:

    • Shelf life of about 1 year requires timely use to prevent degradation
    • Limited capacity may be inadequate for larger household composting needs

    Best for: Homeowners with small countertop compost bins who prioritize durability and ease of handling.

    Not ideal for: Users needing long-term storage or larger capacity composting, as the shelf life and size limit versatility.

    • Capacity:1.6 gallons (6L)
    • Dimensions:16.1 in x 19.3 in
    • Thickness:0.63 mil
    • Count:50 bags per roll
    • Certifications:BPI, OK compost INDUSTRIAL, TÜV Seedling
    • Shelf Life:Approx. 1 year
    Our verdict

    “This pick makes the most sense for users who want a compact, durable, and easy-to-handle compost bag for small food scraps.”

12. 1.6 Gallon Tie Handles Compost Trash Bags, 120 Food Scrap Bags, Compostable Kitchen Waste Bags, EN13432 & ASTM D6400 Certified

    

    Best for Larger Volume Kitchen Waste with Strong, Eco-Friendly Design

    View on Amazon
    Compared with SUPERBIO’s smaller, handle-tie bags, this set offers greater volume and quantity, making it suitable for larger households or frequent composting. Its biodegradable materials like corn starch and PBAT guarantee eco-friendliness, and the strong construction ensures reliable use during food waste collection. The easy-tie handles improve convenience, but proper storage is critical to prevent premature degradation, especially given its limited 18-month shelf life. While it’s bulkier and more versatile for kitchen waste, the specific storage conditions might pose challenges for some users. If you prioritize quantity and durability over size, this model provides a compelling balance of eco-friendliness and strength.
    Pros:

    • Biodegradable and made from environmentally friendly materials
    • Strong, durable construction suitable for daily kitchen use
    • Easy-tie handles for secure and mess-free closure

    Cons:

    • Must be stored properly to prevent degradation, complicating long-term storage
    • Limited shelf life of about 18 months may require careful inventory management

    Best for: Larger households or busy kitchens needing a high-volume, durable compost bag that handles frequent waste collection.

    Not ideal for: Individuals with limited storage space or who require long-term storage, since its shelf life is limited and proper storage is necessary.

    • Capacity:1.6 Gallon
    • Dimensions:28 in x 13.8 in + 4.7 in x 0.7 mils
    • Number of Bags:120
    • Certification:EN 13432 & ASTM D6400
    • Material:Biodegradable (corn starch, PBAT)
    • Shelf Life:18 months
    Our verdict

    “This pick fits best for those needing high-volume, eco-conscious composting with reliable strength and convenience for frequent use.”

How We Picked

The products were evaluated based on a combination of durability, size options, compostability certifications, value, and user convenience features like drawstrings or handles. We prioritized bags that meet industry standards such as ASTM D6400 or EN13432, ensuring they break down effectively in composting environments. The ranking also considers price per bag and overall usability, balancing affordability with performance. Our goal was to identify options suitable for different household needs while maintaining transparency about potential tradeoffs, such as thickness versus cost or size versus strength.

Factors to Consider When Choosing Compostable Trash Bags

When choosing compostable trash bags, it’s important to consider factors beyond just the environmental labels. Size compatibility ensures the bags fit your bins without excess waste, while durability prevents leaks and tears during use. Certifications confirm the bags truly decompose in composting conditions, not just biodegrade. Price per bag can vary significantly based on thickness, size, and brand, so evaluate what offers the best value for your specific needs. Additionally, features like drawstrings or handles can improve usability but may influence the bag’s strength, especially if quality is compromised. Being aware of these broader considerations helps you make an informed decision that balances environmental impact with practical use.

Size and Fit

Choosing the right size is essential to avoid waste and ensure the bags fit your bins properly. Smaller bags, like 2.6-gallon sizes, are perfect for kitchen compost bins or small waste containers, while 13-gallon bags suit standard kitchen trash cans. Oversized bags can be wasteful and harder to manage, especially if they don’t fit snugly. Conversely, overly small bags may tear or overflow when filled beyond capacity. Take measurements of your bins before purchasing, and consider whether a pack includes different sizes for various uses.

Durability and Thickness

Durability depends largely on the bag’s thickness, measured in mils. Thicker bags, such as those with 0.9 mil or more, tend to resist tears and leaks better, especially when handling heavier or wetter waste. However, increased thickness often results in a higher price per bag. For light waste, thinner options may suffice and save money, but they risk tearing if overloaded. Consider your typical waste load and moisture level to select a bag that balances strength with cost-effectiveness.

Certification and Compostability Standards

Not all biodegradable claims are equal. Look for bags certified under standards like ASTM D6400 or EN13432, which guarantee the product will break down within specific timeframes in commercial composting facilities. These certifications are a sign that the bags are truly eco-friendly and won’t persist in landfills or harm compost quality. Be cautious of bags labeled simply as biodegradable without certification, as they may not fully decompose or may require industrial conditions to do so.

Cost and Value

Price per bag varies widely, often influenced by thickness, size, and brand reputation. Bulk packs tend to offer better overall value, but it’s important to ensure the included sizes match your needs. Sometimes, paying a premium for a certified, thicker, or more durable bag translates into fewer leaks and less frustration—worth considering if you generate heavy or wet waste regularly. Conversely, if you only need occasional use, smaller or less expensive packs might be more economical.

Ease of Use and Additional Features

Features like drawstring handles or tie closures enhance convenience, especially when disposing of wet or heavy waste. These features can also prevent spills and make bag removal easier. However, poorly designed handles or overly bulky drawstrings may compromise the bag’s integrity, causing tears or difficulty filling. Consider how often you’ll need to replace or empty bags, and whether additional features justify any extra cost or potential durability tradeoffs.

Frequently Asked Questions

Are compostable trash bags suitable for all types of waste?

Compostable trash bags are best suited for organic waste, such as food scraps and yard waste, that will go into composting systems. They are typically not designed for non-organic trash like plastics or metals. Using them for wet or heavy waste can sometimes cause tearing if the bags aren’t sufficiently thick or strong. Always check the product specifications to ensure they match your waste type and volume to avoid leaks or tears.

Can compostable trash bags be used in regular landfills?

Yes, compostable trash bags can be used in regular landfills, but their eco-friendly benefits are most effective when they are composted properly. In landfills, the conditions are often anaerobic and not optimized for decomposition, so they may persist longer than in composting facilities. If your goal is to reduce plastic waste, using them in conjunction with composting is the best approach, but they are not a solution for waste disposal in all environments.

How do I know if a compostable bag is truly eco-friendly?

Look for certifications like ASTM D6400 or EN13432, which verify that a product will biodegrade within a specific time in industrial composting conditions. These standards ensure the bags are not only biodegradable but also compostable, meaning they break down into non-toxic components that enrich the soil. Avoid products that only claim to be biodegradable without certification, as they may not decompose fully or quickly enough to make a real environmental difference.

Are thicker compostable bags worth the extra cost?

Thicker compostable bags generally provide better tear resistance and can handle wetter or heavier waste without leaking. If you frequently dispose of moist or bulky waste, investing in thicker bags can save money by reducing spills and the need for frequent replacements. However, for light, dry waste, thinner options may suffice and help keep costs down. Weigh your typical waste load and budget to decide whether the added durability justifies the price.

Can I use compostable trash bags with regular trash liners?

Yes, compostable trash bags can replace standard liners in most household trash bins. They are designed to fit typical sizes and can be used just like conventional bags. Just ensure they are certified compostable and suited for the waste you intend to dispose of. Keep in mind that they are best used for organic waste to maximize their environmental benefits; mixing with non-organic waste does not diminish their utility but reduces the composting value.
