For a more budget-friendly option, the UNNI Compostable Bags offers a solid blend of performance and affordability. If you need smaller liners, the GreFusion Compostable Bags are ideal for countertop bins. The challenge lies in balancing eco-friendliness with performance—thicker bags tend to be more durable but may cost more or contain less compostable content.

Key Takeaways
- Thicker bags (around 0.9-1 mil) generally provide better durability but can be slightly more expensive or less flexible in composting processes.
- Standards like ASTM D6400 or EN 13432 are essential to ensure true compostability, not just biodegradability.
- Size compatibility is crucial; over- or under-sized liners can cause messes or waste space, so measure your bins carefully.
- Handles and drawstrings add convenience but may vary in strength and ease of use depending on the brand.
- Cost per bag tends to decrease with larger pack sizes, but quality and compostability standards must still be a priority.

Simply Bio 13 Gallon Compostable Organic Bags Liners Drawstring, Heavy Duty Extra Thick 1 Mil, 49.21 Liter, 30 Bags
This option stands out for its combination of heavy-duty 1 mil thickness and certified compostability, making it suitable for households or small businesses aiming for reliable waste containment. Compared with the UNNI Compostable Bags, it offers slightly thicker material, which can handle heavier or sharper waste without tearing. However, its capacity is limited strictly to 13 gallons, which might be a drawback for larger waste loads. The drawstring feature simplifies disposal, and the certification to ASTM D6400 and EU EN 13432 assures eco-conscious consumers of its compostability. Still, availability can vary, and the thickness may not suffice for very heavy or mixed waste. This pick makes the most sense for users who prioritize durability and certified compostability in a standard-sized bin.
Pros:- Made from sustainable, plant-based materials
- Heavy-duty 1 mil thickness resists leaks and tears
- Certified compostable to international standards
- Includes convenient drawstring for easy handling
Cons:- Limited to 13-gallon capacity, not suitable for larger bins
- Thickness may be insufficient for very heavy or sharp waste
Best for: Homeowners or small restaurants needing durable, certified compostable liners for daily kitchen waste
Not ideal for: Large commercial facilities or bins exceeding 13 gallons, where thicker or larger capacity liners are required
- Capacity:13 gallons
- Number of Bags:30
- Material:Polylactic Acid (PLA) and PBAT
- Thickness:1 mil
- Dimensions:Width 23.7 in. x Height 29.4 in.
- Item Weight:2.1 pounds
Our verdict“This is ideal for eco-conscious users who need a reliable, certified compostable bag for standard kitchen waste.”
SUPERBIO 13 Gallon Compostable Kitchen Waste Bags with Handles
This pick is tailored for users who need reinforced handles and tear-proof durability, making it especially suited for outdoor or heavy kitchen waste. Compared to the UNNI Compostable Bags, the handles provide a more secure grip for disposal and tie-off, but the slightly thinner 0.87 mil material offers less resistance to very sharp or heavy debris. It is certified by BPI and OK compost HOME, ensuring eco-friendliness, yet its shelf life of about one year might be limiting for long-term storage. The larger dimensions (36.6 inches long) also accommodate more waste, but the bulkier size may be less convenient for small or tight spaces. This product makes the most sense for those prioritizing reinforced features and outdoor composting compatibility.
Pros:- Reinforced handles for easy tying and carrying
- Certified by reputable standards (BPI, OK compost HOME)
- Strong, tear-resistant material
- Suitable for outdoor and indoor composting
Cons:- Shelf life of roughly one year may limit storage
- Slightly thinner material than some competitors, less resistant to very sharp waste
Best for: Home gardeners or outdoor composters needing durable, handle-equipped bags for yard or kitchen waste
Not ideal for: Users seeking a budget-friendly option for small indoor bins, as the handles add to cost and bulk
- Capacity:13 gallons
- Material:PLA+PBAT
- Dimensions:22.8 in x 36.6 in
- Thickness:0.87 mil
- Number of Bags:30
- Shelf Life:1 year
Our verdict“This bag is best for users who need extra strength and handles for outdoor or heavy-duty kitchen waste management.”
UNNI Compostable Bags, 13 Gallon, 50 Count, Extra Thick 0.9 Mil
This model excels in offering extra thickness at 0.9 mil, providing a durable barrier for kitchen, bathroom, or office waste. Compared with the Simply Bio bags, it offers a slightly thinner but still robust construction, with reinforced sides for added strength. Its fit for standard tall kitchen cans makes it versatile for various indoor settings, yet its 9-month recommended use window might be limiting for long-term storage. The large 50-count roll offers good value, but commercial composting options may not be accessible everywhere, so it’s better suited for household use. The bags balance durability with eco-friendliness, but the slightly shorter shelf life is a consideration for storage planning.
Pros:- Made from plant-based, compostable materials
- Reinforced for extra durability
- Fits standard tall kitchen cans
- Good value with 50 bags per roll
Cons:- Use within 9 months for optimal performance
- Limited availability of commercial composting options
Best for: Eco-conscious households seeking durable, standard-size compostable bags for daily kitchen or office waste
Not ideal for: Large-scale commercial use or outdoor composting, where heavier or larger capacity bags are needed
- Capacity:13 gallons / 49.2 liters
- Quantity:50 bags
- Thickness:0.9 mil
- Material:Plant-based, compostable
Our verdict“This bag provides a durable, eco-friendly option for households wanting reliable compostable liners for everyday use.”
Biodegradable 13-17 Gallon Code-Q Trash Bags (50 Pack) | Heavy-Duty Tall Green Kitchen Bags with Drawstring | Fits Standard Cans | Eco-Friendly D2W, 30 Micron Thick, 25.6″ x 33.5″
This option is designed for users who need heavy-duty, larger capacity bags that can handle tough waste like yard debris or larger kitchen loads. With a thickness of 30 microns, it surpasses many competitors like the Simply Bio, providing extra strength for sharp or heavy waste. The use of oxo-biodegradable D2W technology means faster breakdown, but it may not meet strict compostability standards, which could be a concern for some eco-conscious buyers. Its size (up to 17 gallons) makes it flexible, but the higher cost and thicker material may be unnecessary for those with smaller or less demanding waste streams. This bag is well-suited for outdoor use or heavy-duty indoor applications where durability is a priority.
Pros:- Heavy-duty 30-micron thickness for tough waste
- Biodegradable with faster breakdown via D2W technology
- Secure drawstring closure for convenient handling
- Fits 13-17 gallon cans
Cons:- More expensive than lighter, standard compostable bags
- Oxo-biodegradable D2W may not meet strict compost standards
Best for: Yard waste collectors or outdoor composters needing robust, large-capacity liners
Not ideal for: Indoor users with small, light waste, as the thicker material might be overkill and more expensive
- Capacity:17 gallons
- Material:Medium Density Polyethylene, Biodegradable, Decomposable
- Material Thickness:30 Micron
- Item Dimensions:25.59 x 33.46 inches
- Unit Count:50
- Color:Green
Our verdict“This bag is best suited for those needing sturdy, large-capacity liners for outdoor or heavy-duty waste disposal.”
UNNI 2.6 Gallon Compostable Bags, 100 Count, 10 Liter, Extra Thick 0.71 Mil
This product excels for small-scale waste needs, as its compact 2.6-gallon capacity and extra-thick 0.71 mil material make it ideal for food scraps or small bins. Compared with the larger Simply Bio or UNNI 13 Gallon options, this offers a very tailored fit for countertop or under-sink bins, with the advantage of extra durability. The high quantity (100 bags) provides excellent value, but its small size limits versatility for larger waste streams. The certification of compostability makes it suitable for home composting, but commercial composting options may be limited depending on local facilities. It’s perfect for those who want a reliable, eco-friendly solution for small kitchen scraps without the bulk or cost of larger liners.
Pros:- Extra thick 0.71 mil for durability
- Made from plant-based, compostable materials
- Perfect fit for small kitchen or countertop bins
- High quantity offers good value
Cons:- Limited capacity unsuitable for large waste loads
- Use within 9 months recommended for best performance
Best for: Home cooks or small office spaces needing durable, compact compostable waste bags
Not ideal for: Larger households or outdoor use, where bigger capacity or heavier waste is common
- Capacity:2.6 gallons / 10 liters
- Quantity:100 bags
- Thickness:0.71 mil
- Material:Plant-based, compostable
Our verdict“This bag is best for small households or kitchens seeking a durable, eco-friendly liner for food scraps and small waste containers.”
AYOTEE 13-15 Gallon Tall Kitchen Biodegradable Trash Bags, 60 Count
This option stands out for its balance of eco-conscious materials and reliable leak protection, making it ideal for those who want to reduce plastic waste without sacrificing durability. Compared with Compostable Trash Bags – 13 Gallon Tall Kitchen Garbage Liners, it offers a similar capacity but with a thicker material (1.18 mil versus 0.9 mil), which translates into better wet waste containment. However, its less robust performance in highly saturated conditions is a tradeoff to note. The dispenser box adds convenience for frequent kitchen use, especially in busy households. Overall, this pick makes the most sense for eco-minded consumers who need a sturdy, large-capacity bag that simplifies waste management while being biodegradable.
Pros:- Eco-friendly and biodegradable, reducing plastic waste
- Strong and leak-proof for wet waste up to 5 days
- Large size fits 13-15 gallon trash cans
- Dispenser box for easy, organized use
Cons:- Not suitable for highly saturated or heavy liquids
- May be less durable in extremely damp conditions
Best for: Eco-conscious households seeking reliable, large-capacity biodegradable bags for wet kitchen waste
Not ideal for: Homes with extremely wet or heavy liquids, as the bags may leak under saturation
- Capacity:13-15 gallons
- Material:Plant-based, biodegradable cornstarch blend
- Dimensions:23.6″ x 31.5″
- Thickness:1.18 mil
- Count:60 (4 rolls, 15 per roll)
Our verdict“This bag is ideal for eco-conscious users who prioritize strength and capacity in their biodegradable kitchen liners.”
Compostable Trash Bags – 13 Gallon Tall Kitchen Garbage Liners, Unscented, 80 Count, Green
This pick makes the most sense for those looking for a straightforward, environmentally friendly bag for everyday kitchen or office waste, with the added benefit of a clear green color for content identification. Compared with AYOTEE 13-15 Gallon Bags, it offers a slightly smaller capacity (13 gallons versus 15), but emphasizes durability and leak resistance, making it a solid choice for general waste disposal. Its plant-based bioplastic material is suitable for backyard composting, unlike some thinner options. A potential drawback is the higher cost relative to non-compostable alternatives, which might deter budget-conscious buyers. Overall, this product suits those who want a reliable, compostable bag that blends seamlessly into various environments.
Pros:- Eco-friendly and compostable material
- Strong and durable with leak resistance
- Suitable for various household uses
- Clear green color for content visibility
Cons:- Limited to 13-gallon bin sizes
- Green color may not match all decor
- Potentially higher cost compared to non-compostable bags
Best for: Homeowners or small offices seeking durable, compostable liners compatible with standard 13-gallon bins
Not ideal for: Large households with heavy or wet waste that demand maximum capacity or strength
- Capacity:55 liters
- Count:80
- Item Weight:3 pounds
- Item Dimensions:6.5 x 2.75 x 11.8 inches
- Material:Plant-based bioplastic
Our verdict“This bag is perfect for eco-conscious users needing a durable, versatile compostable liner for everyday waste.”
GreFusion Compostable Bags 1.2 Gallon, 125 Count, Fits Small Countertop Bins
This product excels for users with limited space or small waste bins, such as in bathrooms or compact kitchens. Its size (1.2 gallons) and fit-specific dimensions (diameter ≤ 10 inches, height ≤ 11 inches) mean it won’t work in larger cans, but its leak-proof, odor-resistant features make it ideal for sensitive environments. Compared to larger capacity options like AYOTEE 13-15 Gallon Bags, it emphasizes eco-friendliness and convenience for small-scale waste. Its frequent need for replacement if waste volume is high could be a downside. Overall, this makes a strong choice for those prioritizing small, eco-friendly liners for daily use in limited spaces.
Pros:- Certified compostable and environmentally friendly
- Leak-proof and tear-resistant for heavy waste
- Odor-resistant to keep small spaces fresh
- Fits small countertop bins perfectly
Cons:- Limited to small-sized bins only
- May require frequent replacement in high-waste scenarios
- Specific size may not fit larger bins
Best for: People with small countertop or bathroom trash bins needing eco-friendly, leak-proof liners
Not ideal for: Homes or offices with high waste volume, where frequent bag changes would be inconvenient
- Capacity:1.2 gallons
- Count:125
- Dimensions:15.7 inches x 15 inches
- Material:Corn starch
Our verdict“This pick is perfect for small spaces where eco-friendly, leak-proof liners are needed without bulk.”

This heavy-duty option stands out for its extra thick (1 mil) construction and drawstring closure, making it ideal for handling food scraps and organic waste that can be messy or heavy. Compared with AYOTEE 13-15 Gallon Bags, it emphasizes durability over capacity, with a focus on tear resistance and reliable handling. Its certification by BPI and ASTM D6400 ensures proper compostability, but its smaller quantity (35 bags) and higher thickness mean it might be less suitable for high-volume waste or larger households. The need to dispose of waste promptly to prevent odors is a key consideration. Overall, this bag makes sense for users who want a tear-resistant, compostable bag for kitchen organics that won’t rip during transport.
Pros:- Made from certified compostable materials
- Heavy-duty and tear-resistant for reliable use
- Drawstring for easy handling
- Suitable for organic food scraps
Cons:- Limited quantity (35 bags) for high-volume use

- Capacity:13 gallons
- Size:25.2 in x 25.6 in
- Thickness:1 mil

Our verdict“This bag is ideal for eco-conscious individuals needing a durable, organic waste container liner for kitchen scraps.”

This product is tailored for those with small waste needs, such as kitchen scraps or outdoor composting, thanks to its 2.6-gallon capacity and plant-based materials that fully break down within 6-12 months. Compared to larger bags like Compostable Trash Bags – 13 Gallon, it offers a more specialized solution for garden or small kitchen use, with the added benefit of 110 bags plus 10 bonus ones. Its durability and resistance to rips make it suitable for outdoor use, but its limited size means it won’t replace larger capacity bags for heavy or voluminous waste. The requirement for a proper composting setup might limit its appeal for some users.

Pros:- Made from eco-friendly, compostable materials
- Extra thick and resistant to rips and leaks

Our verdict“This product is best suited for eco-conscious gardeners or small households with limited organic waste needs.”
SUPERBIO 13 Gallon Compostable Drawstring Kitchen Waste Bags, 30 Count
This set of SUPERBIO 13-gallon compostable bags stands out for combining certified eco-friendliness with tear-resistant durability, making them ideal for everyday kitchen waste. Compared to the UNNI Compostable Bags, which are slightly thicker but lack the same industrial certification, SUPERBIO offers peace of mind on environmental standards. However, their availability in commercial composting facilities can be limited, and they should ideally be used within a year to maintain quality. The tear-resistant design minimizes messes during removal, but the recommended disposal timeframe is tight for organic waste. These bags are best suited for households with access to reliable composting options and a focus on certified sustainability.
Pros:- Made from biodegradable and certified compostable materials
- Tear-resistant and durable during use
- Certified by reputable standards (BPI, OK compost INDUSTRIAL)
Cons:- Limited availability of commercial composting facilities in some areas
- Shelf life of about 1 year if stored improperly
Best for: Environmentally conscious households that prioritize certified compostability and durability in kitchen waste disposal
Not ideal for: Homes without access to commercial composting facilities or those seeking budget-friendly, long-term storage options
- Capacity:13 gallons (49.2L)
- Dimensions:25.2 in x 25.6 in
- Thickness:1 mil
- Count:30 bags per roll
- Certifications:BPI, OK compost INDUSTRIAL, SEEDLING
- Standards:ASTM D6400, EN 13432
Our verdict“This pick is best for eco-conscious users who want certified, durable bags for daily kitchen waste, provided they have access to suitable composting options.”
13 Gallon Compostable Trash Bags – 100 Count
This set of 100 compostable bags made from plant starch (corn) offers a cost-effective solution for frequent waste disposal. Unlike the SUPERBIO option, which is more premium and certified for industrial composting, these bags prioritize bulk affordability and versatility, suitable for both indoor and outdoor use. Their thickened, tear-resistant design minimizes leaks, but they may be less suited for heavy, wet organic waste compared to the SUPERBIO bags. Additionally, their size fits most standard 13-gallon cans, though they might not work well with larger or unusually shaped bins. This product makes the most sense for families or community groups seeking economical, eco-friendly waste options without sacrificing performance.
Pros:- Cost-effective for high-volume use
- Made from biodegradable plant starch (corn)
- Thickened and leak-resistant design
Cons:- Limited to 13-gallon capacity, not suitable for larger bins
- Less certification compared to premium options like SUPERBIO
Best for: Large households or community groups needing a budget-friendly, eco-conscious bag bulk option
Not ideal for: Users with oversized or non-standard bins over 15.3 inches in diameter, or those requiring industrial-grade certification
- Capacity:13 gallons
- Count:100 bags (2 rolls of 50)
- Material:Plant starch (corn)
- Dimensions:24 inches x 30 inches
- Certifications:BPI, OK COMPOST, Seedling Certified
Our verdict“This bulk pack is perfect for budget-minded users seeking reliable, eco-friendly waste bags for regular household use, as long as their bins are standard-sized.”
Compostable Trash Bags – 8 Gallon, 150 Count, Green, Unscented, Durable & Thick
This set of 8-gallon compostable bags provides a compact, environmentally friendly option for smaller waste bins, such as those in offices or kitchens. Compared with the larger 13-gallon options like SUPERBIO or the bulk 13-gallon set, these are tailored for medium-sized containers. Their tear-resistant, sealed octagonal bottom enhances leak prevention, but their thinner 0.5 mil material means they might be less durable for very wet or heavy organic waste. Their unscented design keeps odors neutral, making them suitable for indoor use. However, their size limits their use to smaller or medium bins, and they are typically more expensive per bag than larger-volume options. This makes them ideal for users needing a reliable, eco-friendly solution for smaller waste volumes.
Pros:- Eco-friendly and certified compostable
- Strong, leak-proof design with sealed bottom
- Unscented for odor control
Cons:- Limited to 8-gallon capacity, not suitable for larger bins
- More expensive per bag compared to larger pack sizes
Best for: Homeowners or small office managers with medium-sized (8-gallon) bins seeking a sturdy, eco-friendly bag option
Not ideal for: Large households or outdoor waste collection where bigger or more robust bags are needed, due to size and durability limits
- Size:21 x 25.2 inches
- Thickness:0.5 mil
- Capacity:8 gallons
- Count:150
- Material:Plant starch (biomaterial)
- Certifications:ASTM D6400, EN 13432
Our verdict“This set is ideal for small to medium households and offices wanting a reliable, eco-friendly, and leak-resistant compostable bag for everyday use.”
How We Picked
The products in this roundup were selected based on their certification for compostability, durability, size compatibility, and user reviews. I prioritized bags that meet recognized standards like ASTM D6400 or EN 13432 to ensure they truly break down in composting environments. Performance factors such as thickness, strength, and ease of sealing were also key. Price and pack size were considered to provide a balanced view for different budgets and needs. The ranking reflects a combination of these factors, focusing on products that deliver reliable eco-friendly performance without sacrificing usability or value.Factors to Consider When Choosing Compostable Trash Can Liners
Choosing the right compostable trash can liners involves understanding several key factors. Not all compostable bags are created equal—some focus on strength, others on environmental certification, and some on size compatibility. Making an informed choice can prevent frustration from bags tearing or not fitting properly. Here are the main considerations to keep in mind before purchasing.Certification and Standards
Look for bags certified under recognized standards like ASTM D6400 or EN 13432. These certifications ensure the bags will break down in commercial composting facilities within a reasonable time frame. Non-certified bags may only be labeled ‘biodegradable’ without guaranteed compostability, which can lead to environmental concerns or disposal issues.
Thickness and Durability
Thicker bags (around 0.9-1 mil) tend to resist tears and leaks better, especially when handling wet waste. However, thicker bags may also be less flexible or slightly more expensive. Balance your needs for durability with environmental impact, as some thinner bags still meet compostability standards.
Size and Fit
Accurately measure your trash cans before buying. Overly large or small liners can cause spills or waste space. Many brands specify their bags’ dimensions—matching these to your bin size ensures a snug fit, reducing the risk of tearing or slipping inside the can.
Ease of Use and Features
Features like drawstrings or handles can make bag removal and sealing easier. Consider whether these features add convenience without compromising strength. For example, a drawstring that tears easily isn’t helpful, so check reviews for real-world performance.
Cost and Pack Size
Prices per bag decrease with larger packs, but consider your actual usage and storage space. Higher-quality bags may cost more upfront but can save money over time by reducing waste from tears or leaks. Balance your budget with the need for reliable, eco-friendly performance.
Frequently Asked Questions
Are all compostable trash bags suitable for home composting?
Not necessarily. Many compostable bags are designed for commercial composting facilities, which operate at higher temperatures and specific conditions. Some bags are suitable for home composting if they meet certain standards, but always check the packaging or product details. For home composting, look for bags explicitly labeled as suitable for that environment to ensure they break down properly without leaving residues.
Can I use compostable liners in my regular trash can?
Yes, compostable liners can be used in standard trash cans, provided they fit well. They are a good eco-friendly alternative to traditional plastic bags, especially if you separate waste for composting. Just ensure the bags are the right size and thickness for your waste volume, and that you dispose of them in appropriate composting facilities when possible.
Do thicker compostable bags take longer to decompose?
Thicker bags might take marginally longer to break down because of their density, but the difference is usually minimal if the bags meet appropriate compostability standards. The key is choosing bags with the right balance of thickness for durability and certification for quick breakdown. Thicker bags often last longer during use but still should compost within a reasonable timeframe under proper conditions.
Are compostable trash bags more expensive than regular plastic bags?
Generally, yes. Compostable bags tend to cost more because of the materials and certifications involved. However, the price difference diminishes with larger pack sizes, and many find the environmental benefits worth the extra cost. Investing in certified compostable bags helps ensure they truly break down and don’t add to plastic pollution.
What should I do if my compostable bag tears in the trash can?
If a bag tears during use, it’s a sign that the thickness or quality might not be suitable for your waste type. To prevent this, opt for bags with higher mil ratings if handling wet or heavy waste. Also, ensure the bag fits well in your bin—overstuffing can increase the risk of tears. Regularly inspecting your bags and choosing reputable brands can reduce this issue.
Conclusion
For those seeking the best overall performance, the Simply Bio 13 Gallon Compostable Organic Bags offers excellent durability and reliable compostability. Budget-conscious buyers will appreciate the value of the UNNI Compostable Bags, which balance affordability with eco-friendliness. If you’re new to composting or want small liners for countertop use, the GreFusion Compostable Bags provide a simple, effective solution. For premium quality and advanced features, consider higher-end options that meet strict standards, especially if your waste volume is high or you need extra strength. Ultimately, your choice should reflect your specific waste management needs, environmental priorities, and budget constraints.
