More Details on Our Top Picks
Emily’s Choice Biodegradable Heavy Duty Trash Bags (50 count), 18 Gallon Capacity, 2 Mil Thickness
Emily’s Choice bags stand out for their combination of large capacity and durability, making them ideal for households generating significant compostable waste. Compared to the GreFusion Bags, they offer a thicker 2-mil build, which enhances strength for heavy loads but comes at a higher price point. Their high-performance LDPE material ensures biodegradability, though actual decomposition depends on environmental conditions, not always guaranteed in all composting setups. The custom flex fit reduces waste volume effectively, which is a plus for minimizing trash overflow. However, their cost and reliance on proper environmental conditions for biodegradation are tradeoffs. This pick is best suited for users who need heavy-duty, eco-friendly bags that can handle large amounts of waste regularly.
Pros:- Biodegradable and environmentally friendly
- Large capacity reduces trash volume significantly
- Durable 2 mil thickness for heavy-duty use
- Custom flex fit design for secure fit
Cons:- May be more expensive than standard trash bags
- Biodegradation depends on environmental conditions
Best for: Households with large compost bins and heavy waste loads who prioritize durability.
Not ideal for: Small apartment dwellers with limited space or infrequent composting needs, due to higher cost and larger size.
- Material:LDPE
- Capacity:18 gallons
- Count:50
- Thickness:2 mil / 50.1 Micron
- Technology:D2W Biodegradable Technology
- Dimensions:68.1L / 18 Gallons

13 Gallon Compostable Trash Bags Drawstring, Heavy Duty Extra Thick 1 Mil, 35 Bags
This roll of 35 compostable bags offers a solid balance of affordability and certification, making it ideal for eco-conscious households that want reliable disposal options without breaking the bank. Compared to the Compostic bags, these feature a slightly thicker 1-mil material, enhancing tear resistance and durability for everyday kitchen waste. Their ASTM D6400 and BPI certifications ensure compliance with strict composting standards, but they are less suited for composting facilities with limited acceptance or for long-term storage, as shelf life is around a year. The drawstring design simplifies waste handling, though the bags are only suitable for 13-gallon bins, limiting versatility. This product is best for users seeking certified compostable bags that balance cost with eco-friendly features.
Pros:- Made from biodegradable, compostable materials
- Tear-resistant and durable for heavy use
- Includes 35 bags per roll with drawstring for convenience
- Certified by BPI and ASTM D6400
Cons:- Limited to 13-gallon capacity
- Shelf life of approximately 1 year
- Requires access to local composting facilities
Best for: Home cooks and families wanting certified compostable bags for regular kitchen waste on a budget.
Not ideal for: Large households with high waste volume, as the 13-gallon size may fill quickly, requiring more frequent replacement.
- Capacity:13 gallons
- Size:25.2 in x 25.6 in
- Thickness:1 mil
- Bags per roll:35
- Certifications:ASTM D6400, BPI
Bottom line: This roll offers reliable, certified compostable bags ideal for budget-conscious households focused on environmental impact.
Compostic Compostable Trash Bags, 13 Gallon Tall Kitchen, 50 Count
Compared with thinner bags like the 13 Gallon Drawstring Bags, the Compostic bags emphasize tear resistance and strength, which makes them a reliable choice for tall kitchen bins. Their plant-based biopolymers decompose fully within 12 to 24 weeks, leaving no microplastics, which is a significant benefit over non-degradable options. The fully compostable certification and non-toxic, unscented profile appeal to eco-conscious users who want safe, home-compostable waste solutions. However, this strength comes with a higher price and their decomposition time can vary based on composting conditions, which might not be ideal for those seeking quick breakdown or using non-compatible composting facilities. This product is suited for users who want environmentally safe bags that can handle daily kitchen waste reliably.
Pros:- Extra strong and tear-resistant
- Fully compostable within 12-24 weeks
- Made from plant-based biopolymers
- Certified non-toxic and unscented
Cons:- More expensive than traditional plastic bags
- Decomposition time varies with compost conditions
Best for: Home composters needing extra-strength, fully compostable bags for daily kitchen use.
Not ideal for: Users with limited or no access to composting facilities, as the bags rely on proper composting conditions for full decomposition.
- Capacity:13 gallons
- Unit Count:50
- Materials:Biopolymers
- Material Features:Compostable
- Color:Light Green
Bottom line: This is an excellent choice for eco-conscious households seeking durable, home-compostable waste bags with reliable biodegradation.

GreFusion’s smaller 1.2-gallon bags are tailored for compact countertop bins, making them perfect for food scraps and small waste loads. Their corn starch composition ensures they are fully biodegradable and meet strict standards, similar to the Superbio Food Scrap Bags, but with a slightly higher count for extended use. Their leak-proof and tear-resistant design makes them reliable for everyday small waste, and their size fits most tiny bins in kitchens or bathrooms. The main limitation is their size—these bags are not suitable for larger bins, which could necessitate multiple replacements.

Pros:- Certified biodegradable and compostable
- Leak-proof and tear-resistant

Bottom line: This product is perfect for small, frequent waste disposal in eco-conscious settings where space is limited.
SUPERBIO 1.6 Gallon Handle Tie Compostable Food Scrap Bags, 50 Count
This set of SUPERBIO 1.6-gallon handle-tie bags excels for those with compact countertop bins, providing a tear-proof, handle-tie design that simplifies disposal. Compared with larger-capacity options like Green Earth’s 13-gallon bags, these are ideal for small spaces but not suited for larger waste volumes. Their certification by BPI and OK compost INDUSTRIAL ensures environmentally friendly disposal, but they rely on industrial composting facilities, which aren’t available everywhere. The limited shelf life of about a year means they’re best used promptly, and their size restricts them to organics and small waste loads. These bags make the most sense for urban dwellers or those with limited kitchen space needing a dedicated, tidy solution for food scraps, not for heavy or non-organic waste.
Pros:- Certified compostable by BPI and OK compost INDUSTRIAL standards
- Tear-proof and sturdy handle-tie design for easy handling
- Perfect size for small countertop bins
Cons:- Limited to industrial composting facilities in some regions
- Shelf life of approximately 1 year
Best for: Homeowners with small countertop compost bins or urban residents needing compact organic waste solutions
Not ideal for: Households generating large amounts of waste or those without access to industrial composting facilities
- Capacity:1.6 Gallons
- Unit Count:50
- Item Weight:13.1 Ounces
- Item Dimensions:5 x 3 x 3 inches
- Material:Plant-based Bioplastic
- Style:Handle Tie
Bottom line: This pick is best for those with small-scale composting setups and access to industrial composting, but less suitable for heavy or diverse waste streams.
ANECO 100% Compostable Waste Bags 2.6 Gallon, Extra Thick Kitchen Small Compost Bags, 110 Count
Compared to the SUPERBIO small bags, the ANECO 2.6-gallon compostable bags are designed for a slightly larger capacity and boast extra thickness, making them resistant to rips and leaks during kitchen use. Their composition from cornstarch and plant-based materials ensures they fully break down in 6-12 months, meeting strict ASTM D6400 standards, which makes them suitable for home composting. However, their size limits them to smaller bins, so they aren’t ideal for larger waste loads, unlike the Green Earth 13-gallon bags. Their durability comes at the expense of some flexibility, as thicker plastic can be less pliable. They’re best suited for conscientious households wanting a durable, eco-friendly option for kitchen scraps, but not for heavy-duty or large-volume waste.
Pros:- Made from eco-friendly, fully compostable materials
- Extra thick and resistant to rips and leaks
- Meets ASTM D6400 certification for home and industrial composting
- Includes 10 bonus bags
Cons:- Limited to 2.6-gallon capacity, unsuitable for larger bins
- Decomposition time of 6-12 months may be slow for urgent waste disposal
Best for: Eco-conscious households needing durable, small-capacity compost bags for kitchen scraps
Not ideal for: Large families or those with bigger compost bins requiring higher volume bags
- Capacity:2.6 Gallons
- Unit Count:110
- Item Weight:1.7 Pounds
- Item Dimensions:16.5 x 16.3 inches

Green Earth Compostable Tall Kitchen Food Scrap Trash Bags, 13 Gallon, 50-Count
The Green Earth 13-gallon bags are designed to handle typical kitchen waste, fitting most standard bins with ease. Their certification in both the US and Europe confirms environmental compliance and responsible disposal. The 0.9 mil thickness provides strength and durability, reducing tears during handling, which sets them apart from thinner bags like the Simply Bio 1 Mil options. While they are a good all-round choice for larger households or those who prefer a single bag for daily use, their cost might be higher than regular non-compostable trash bags, and they require access to proper composting facilities. Use within a year is recommended to maintain performance. These bags make sense for eco-minded consumers with ample waste volume but are less ideal if you lack composting infrastructure or need a more budget-friendly option.
Pros:- Certified compostable in US and Europe
- Strong 0.9 mil thickness for durability
- Fits most 13-gallon kitchen cans
Cons:- Requires proper composting facilities
- Use within one year recommended
- Potentially higher cost than conventional trash bags
Best for: Households with 13-gallon bins and access to composting facilities looking for a strong, eco-friendly bag

Compared to thinner bags like Simply Bio, these are better suited for households that generate tougher waste or need a more secure, leak-resistant solution.

They are best for busy kitchens needing reliable, durable compostable bags that can handle varied waste types.
Pros:- Made from certified, compostable materials
- Strong and tear-resistant at 1 mil thickness
- Includes 30 bags per roll for frequent use

Best for: Busy households with large or tough organic waste needing durable, tear-resistant bags
Not ideal for: Small households or those without access to industrial composting, due to disposal limitations
- Capacity:13 gallons (49.2 liters)
- Size:25.2 in x 25.6 in
- Thickness:1 mil
- Certifications:BPI, OK compost INDUSTRIAL, SEEDLING
Bottom line: Best suited for high-demand kitchens that need tough, reliable compostable bags for larger or heavier waste loads.

Compared to the SUPERBIO drawstring bags, these are slightly less robust in tear-resistance but still perform well under typical kitchen demands.

Compared with the UNNI Bags, which are thicker and more durable, Matter bags offer comparable strength while emphasizing biodegradability.

Its 1.18 mil thickness makes it well-suited for kitchen, garden, or household waste, especially for users who need a versatile bag that can withstand tougher conditions.

How We Picked
In selecting these products, I focused on key factors that matter most to eco-conscious consumers: performance, durability, certification standards, and usability. Products were evaluated based on their thickness, material quality, ease of use, and whether they meet recognized compostability certifications like BPI or ASTM D6400. I also considered value for money, availability in different sizes, and overall environmental impact. The ranking reflects a balance between these factors, prioritizing bags that combine reliability with true compostability and affordability for most consumers.Factors to Consider When Choosing Best Compostable Trash Bags
Choosing the best compostable trash bags involves understanding a few essential factors that impact performance, environmental benefits, and value. Not all compostable bags are created equal—some may break down faster, while others may be too thin or expensive for regular use. Being aware of these differences can help you avoid common pitfalls like buying bags that aren’t certified or are too fragile for your waste. Here are key considerations to keep in mind when making your decision.Certification Standards
Look for bags certified by reputable organizations like BPI (Biodegradable Products Institute) or meeting ASTM D6400 standards. These certifications guarantee that the bags will break down properly in commercial composting facilities and won’t contaminate the compost. Non-certified options may not decompose fully or could introduce plastics into your compost, defeating the environmental purpose. Always verify certification labels before purchasing to ensure authenticity.
Thickness and Durability
The thickness of compostable bags, usually measured in mils, directly affects their strength and resistance to tearing. Thicker bags (1 Mil or more) are better for heavier or moisture-laden waste, reducing leaks and spills. However, overly thick bags might be less flexible in composting environments and could slow down decomposition. Conversely, thinner bags may be less durable but can break down faster—so consider your waste type and frequency of use when choosing.
Size and Fit
Choosing the right size ensures the bag fits your bins snugly without excess material sticking out. Smaller sizes are perfect for countertop or small yard waste bins, while larger options suit outdoor compost piles or yard debris. Misjudging size can lead to waste spillage or the need for frequent replacements. Measure your bins and select bags that provide a secure fit without excess slack.
Environmental Impact and Decomposition Time
Not all compostable bags decompose at the same rate. Some are designed to break down within a few months, while others may take longer depending on material composition and environmental conditions. Consider your local composting setup—whether it’s industrial or home composting—and select bags that align with that environment. Faster decomposition reduces waste buildup and supports a more sustainable cycle.
Price and Value
While premium, certified bags often come with a higher price tag, they may offer better durability and environmental assurance. Cheaper, uncertified bags might save money upfront but could compromise on quality or environmental standards. Evaluate how often you’ll need to replace bags and whether paying a premium aligns with your eco-goals. Bulk purchasing can also offer better value for regular use.
Frequently Asked Questions
Are compostable trash bags suitable for outdoor use?
Many compostable trash bags are designed for outdoor use, especially those with thicker material and stronger drawstrings. However, their decomposition rate depends heavily on environmental conditions such as temperature and moisture. For yard waste or outdoor composting, choosing bags that are certified and durable ensures they handle the load without tearing prematurely. Keep in mind that in colder or less humid conditions, decomposition may slow down, so select bags with appropriate specifications.
Can I use compostable trash bags for non-food waste?
Yes, compostable bags are suitable for various types of organic waste beyond food scraps, including yard waste, paper, and biodegradable packaging. However, avoid using them for non-organic waste like plastics or contaminated materials, as this can interfere with composting processes. Always check the certification and intended use on the packaging to ensure compatibility with your waste stream.
How do I dispose of compostable trash bags properly?
To dispose of compostable trash bags correctly, place organic waste inside and then put the bag into a composting facility if available. For home composting, ensure the bag is certified for industrial or home composting and follow local guidelines. Do not throw them in regular trash, as they won’t break down properly in landfills. Proper disposal maximizes their environmental benefit and supports sustainable waste management.
Are all compostable bags free from plastics?
Most certified compostable bags are made from plant-based materials like cornstarch or PLA, which do not contain traditional plastics. However, some cheaper options may include additives or blends that are not fully compostable. Always check for certification labels like BPI or ASTM D6400 to confirm the absence of plastics and the ability to decompose fully in composting conditions.
Is thickness more important than certification when choosing a compostable bag?
Both factors are important but serve different purposes. Certification ensures the bag is environmentally safe and will break down properly, while thickness influences durability. For heavy or moist waste, a thicker bag combined with certification provides peace of mind that it will hold up without tearing. For light, everyday use, thinner certified bags may suffice, especially if quick decomposition is desired.
Conclusion
If you’re searching for the best overall compostable trash bag that balances strength, certification, and value, Emily’s Choice Biodegradable Heavy Duty Trash Bags are the top pick. For those on a budget or with light waste, the Compostic Compostable Trash Bags offer reliable performance at an affordable price. If you prefer premium quality with top certifications, the UNNI Compostable Trash Bags stand out, especially for eco-conscious households. Beginners or casual users should consider smaller sizes like the GreFusion Bags for easy handling. Ultimately, your choice depends on your waste type, budget, and environmental priorities—this guide helps align those factors with your ideal product.
