UNNI Compostable Bags, 13 Gallon, 50 Count, Extra Thick 0.9 Mil
This UNNI 13-gallon compostable bag stands out for its impressive thickness (0.9 mil) and multiple certifications, making it a reliable choice for everyday kitchen waste. Compared with the lighter, less durable options like the UNNI 2.6-gallon bags, it offers greater capacity and strength, ideal for larger, regular trash cans. However, its bulkier size and thicker material may make it less flexible for smaller or more delicate waste streams. Its certification from BPI, CMA, and TÜV AUSTRIA provides peace of mind about its compostability, though it relies on commercial composting availability for full decomposition. This pick makes the most sense for households needing a sturdy, certified compostable bag that can handle regular kitchen waste without tearing.
Pros:- Extra thick (0.9 mil) for durability during daily use
- Certified compostable by multiple organizations, ensuring environmental credibility
- Fits standard tall kitchen cans comfortably
- Made from plant-based, sustainable materials
Cons:- Requires access to commercial composting facilities for proper disposal
- Bulkier and less flexible for small waste streams or tight spaces
Best for: Families or individuals with standard-sized kitchen trash cans who want reliable, certified compostable bags that handle daily waste without tearing.
Not ideal for: Those with small countertop compost bins or limited space, as the larger size and extra thickness may be cumbersome.
- Capacity:13 gallons
- Unit Count:50
- Item Weight:2.6 pounds
- Item Dimensions:6.42 x 4.41 x 4.41 inches
- Material:compostable
- Material Features:Compostable
Our verdict“This bag is best suited for households seeking a robust, certified compostable option that can stand up to everyday kitchen waste.”
13 Gallon Compostable Trash Bags (40 Count) — Leakproof Plant-based Thick (1.1 Mil) Tall Kitchen Garbage Bags — ASTM D6400 BPI Certified — Heavy-Duty Large Food Scrap Liner Bag with Handle-Tie
This 13-gallon bag is designed with a thicker, 1.1 mil construction, making it especially leakproof and suitable for wet or food-heavy waste. Its reinforced handle-ties improve ease of lifting and sealing, setting it apart from thinner, less reinforced alternatives like the UNNI 13-gallon bags. While the added thickness enhances durability, it also results in a tighter fit when the bag is full, and the heavier weight may be less convenient for some users. Certified by ASTM D6400 and BPI, it guarantees compostability and eco-friendliness. This pick is ideal for those who frequently dispose of moist, heavy, or messy kitchen scraps and need a leak-resistant solution.
Pros:- Thick (1.1 Mil) material for leakproof performance
- Reinforced handle-ties for easy lifting and sealing
- Certified compostable and eco-friendly
- Designed for large kitchen trash cans
Cons:- Less stretch and flexibility when fully loaded
- Tighter fit may cause tearing if overfilled
Best for: Home cooks or families generating wet waste who need leakproof, reinforced, compostable bags for daily food scraps and heavy kitchen waste.
Not ideal for: Users with small, countertop compost bins or those preferring ultra-light, flexible bags for dry waste, as the weight and thickness may feel restrictive.
- Capacity:13 gallons
- Count:40
- Material:Cornstarch, PBAT, PLA
- Thickness:1.1 Mil
- Dimensions:30″ H × 23.5″ W
- Material Features:Compostable
Our verdict“This bag excels for wet, heavy waste disposal where leak resistance and durability are priorities, especially in larger kitchens.”
Compostic Compostable Trash Bags, 13 Gallon Tall Kitchen, 50 Count
This Compostic 13-gallon bag emphasizes rapid, complete decomposition, breaking down fully within 12 to 24 weeks in home compost. Its tear-resistant design surpasses lighter, less durable options like the UNNI 2.6-gallon bags, making it suitable for typical household waste. Made from plant-based biopolymers, it leaves no microplastics, which is a significant advantage for eco-conscious users. The primary tradeoff involves its higher cost compared to standard plastic bags and the dependence on home composting conditions for timely decomposition. Compared to other options like the UNNI Extra Thick, it offers better eco-credentials and faster breakdown, but may require more careful handling to avoid tears during use.
Pros:- Fully compostable within 12-24 weeks in home compost
- Made from plant-based biopolymers, leaving no microplastics
- Extra tear-resistant and durable for household waste
- Certified non-toxic and unscented
Cons:- Higher price point than standard plastic bags
- Decomposition time varies with compost conditions
Best for: Eco-minded households with access to home composting who want a fully biodegradable bag that decomposes quickly and safely.
Not ideal for: Users without a home compost setup or in areas lacking composting facilities, since the decomposition relies on home composting conditions.
- Capacity:13 gallons
- Unit Count:50
- Materials:Biopolymers
- Material Features:Compostable
- Color:Light Green
- Item Form:Bag
Our verdict“This bag is best suited for eco-conscious households equipped for home composting seeking rapid, complete biodegradation of waste.”
UNNI 2.6 Gallon Compostable Bags, 200 Count, 10 Liter, Extra Thick 0.71 Mil
This UNNI 2.6-gallon bag is designed for small kitchen bins, offering a compact size with a thick (0.71 mil) construction that balances durability and flexibility. Unlike the larger 13-gallon options, it fits perfectly in countertop compost containers, making it ideal for daily use. Compared to the 100-count variant, this 200-count pack provides excellent value for frequent waste disposal. However, its smaller capacity means it’s less suitable for larger households or heavy waste loads, and the thickness, while substantial, may still be insufficient for very heavy or sharp waste. Its certified compostability makes it a strong choice for home composters prioritizing convenience and eco-friendliness in limited space.
Pros:- Made from certified compostable materials
- Extra thick (0.71 mil) for durability during daily use
- Large pack of 200 bags provides long-term supply
- Perfect fit for small countertop compost bins
Cons:- Limited capacity for larger households
- Not suited for very heavy or sharp waste loads
Best for: Individuals or small households with limited kitchen space who want reliable, durable compostable bags for daily food scraps.
Not ideal for: Large families or those generating significant waste, as its small capacity and size may require frequent bag changes.
- Capacity:2.6 gallons
- Unit Count:200
- Item Dimensions:4.6 x 4.13 x 4.06 inches
- Material:Compostable
- Thickness:0.71 mil
- Material Features:Compostable
Our verdict“This bag offers reliable, eco-friendly performance for small-scale composting in limited spaces, making it ideal for singles or small households.”
13 Gallon Compostable Trash Bags Drawstring Heavy Duty Extra Thick 1 Mil 35 Bags
This option stands out for its combination of durability and compostability, making it ideal for those who generate heavy waste or food scraps. Compared to the COMPOSTABLE TRASH BAGS – 13 GALLON, 80 COUNT, its extra thickness (1 mil) offers superior tear resistance, especially for mixed or heavier waste streams. The drawstring closure adds convenience, but the bags’ shelf life of about one year and potential incompatibility with some local composting programs are tradeoffs. It’s best for households or small food service operations that prioritize durability and compliance with ASTM D6400 standards.
Pros:- Made from biodegradable and compostable materials, compliant with ASTM D6400
- Extra thick 1 mil material provides tear resistance for heavy waste
- Includes 35 bags with convenient drawstring closure
Cons:- May not be accepted by all local composting facilities, limiting disposal options
- Shelf life of only about 1 year requires proper storage
Best for: Homeowners or small food businesses seeking durable, heavy-duty compostable bags for regular use.
Not ideal for: Those with limited storage space or who rely on local composting programs that do not accept ASTM D6400-certified plastics.
- Capacity:13 gallons
- Material:Biodegradable, Compostable, PBAT
- Thickness:1 mil
- Number of Bags:35
- Dimensions:25.2 in x 25.6 in
- Certifications:ASTM D6400, BPI
Our verdict“This pick is best suited for users needing sturdy, compostable bags that can handle tougher waste loads with reliable closure.”
SUPERBIO 1.6 Gallon Compostable Food Scrap Bags, Handle Tie, 50 Count
Designed specifically for countertop food scrap bins, the SUPERBIO 1.6 Gallon Bags excel in compact, food-focused waste collection. Compared with the larger 13-gallon options like EcoLipak 33 Gallon Compostable Trash Bags, these are perfect for small spaces and daily food scraps, with handle ties that make sealing easy. While their size limits them to kitchen counter use, their plant-based bioplastic ensures they are fully compostable, though they may not suit larger or outdoor waste needs. This makes them ideal for health-conscious households or small cafes focused on composting food waste.
Pros:- Made from biodegradable, plant-based bioplastic
- Strong, tear-proof with reinforced bottom for heavy food scraps
- Includes handle ties for secure closure
Cons:- Limited to 1.6-gallon capacity, unsuitable for larger waste
- Not compatible with standard kitchen trash cans of larger sizes
Best for: Individuals or small cafes managing daily food scraps in limited spaces.
Not ideal for: Users with larger waste volumes or outdoor composting needs, where bigger bags are necessary.
- Capacity:1.6 gallons
- Unit Count:50
- Material:Plant-based Bioplastic
- Style:Handle Tie
- Item Dimensions:5 x 3 x 3 inches
- Certifications:Compostable
Our verdict“This product makes the most sense for small-scale, food-only waste collection in compact spaces.”
Compostable Trash Bags – 13 Gallon, 80 Count, Unscented, Green
Compared with the 50 Count 13-Gallon Bags from other brands, these offer a larger quantity for a similar price, making them a practical choice for households with multiple small bins. Crafted from plant starch material, they are strong enough for typical household waste, with an octagonal bottom that helps prevent leaks under heavy loads. However, their size may not fit larger or irregular bins, and the color might not appeal to everyone depending on waste sorting preferences. They strike a balance for those needing reliable, eco-friendly liners across various small bins in home or office environments.
Pros:- Environmentally friendly and compostable in home composting facilities
- Strong, durable, with an octagonal bottom for better weight distribution
- Suitable for multiple small waste bins and household uses
Cons:- Limited to small bin sizes, not for large waste disposal
- Color may not match waste sorting preferences or aesthetic needs
Best for: Households or offices with multiple small waste bins needing consistent, compostable liners.
Not ideal for: Users with larger trash cans or seeking bags that fit irregularly shaped or larger bins.
- Size:24.8 x 31.4 inches
- Capacity:13 gallons
- Count:80
- Material:Plant starch (biomaterial)
- Certifications:ASTM D6400, EN 13432
Our verdict“This option is best suited for users managing multiple small waste containers seeking eco-friendly liners.”
13 Gallon Compostable Trash Bags, 50 Count
Compared to the 50 Count Compostable Food Scrap Bags, these bags focus on thicker, more durable construction with a double drawstring for secure handling. Made from plant starch (corn), they are designed to withstand heavier loads and resist tearing, making them suitable for outdoor or mixed waste. Their 13-gallon capacity fits most standard kitchen and outdoor trash cans, but their thicker design results in a higher price point and slightly bulkier feel. This makes them a solid choice for outdoor composting or heavier waste streams where durability outweighs cost.
Pros:- Thickened design for tear and leak resistance
- Double drawstrings facilitate easy tying and lifting
- Made from eco-friendly plant starch (corn)
Cons:- More expensive than thinner compostable options
- Designed primarily for 13-gallon bins, less flexible for smaller sizes
Best for: Home users or outdoor settings needing leak-resistant, durable compostable liners for larger or heavier waste.
Not ideal for: Those with small indoor bins or on a tight budget, as these tend to be more expensive than thinner options.
- Capacity:13 gallons
- Count:50
- Material:Plant starch (corn)
- Dimensions:24 in x 30 in
- Material Features:Double drawstrings, leak-resistant
Our verdict“This product is best for users needing heavy-duty, leak-proof compostable bags for outdoor or large waste loads.”
ECOLipak 33 Gallon Compostable Trash Bags, 50 Count
Compared with smaller 13-gallon options like the UNNI 13 Gallon Compostable Bags, the ECOLipak 33 Gallon Bags are designed for substantial outdoor or commercial waste. Made from PLA materials, they decompose within 3-6 months, and their large capacity makes them suitable for yard waste, restaurant waste, or outdoor cleanup. The sturdy construction and bottom seal enhance reliability, but their size limits indoor use and they require cooler, dry storage to maintain quality. This pick is ideal for those who need eco-friendly large waste bags that can handle outdoor conditions and bulkier refuse.
Pros:- Large 33-gallon capacity for outdoor or yard waste
- Decomposes in 3-6 months, suitable for outdoor composting
- Certified by BPI and OK Compost for industrial and home composting
Cons:- Has a corn-based scent that may be off-putting to some users
- Shelf life limited to about 10-12 months, requiring proper storage
Best for: Landscapers, outdoor homeowners, or restaurants managing yard or large-scale waste needing eco-friendly disposal.
Not ideal for: Indoor users with small bins or those who prefer biodegradable bags with longer shelf life for inside use.
- Capacity:33 gallons
- Unit Count:50
- Material:Polylactic Acid (PLA)
- Dimensions:33.08 in x 38.98 in
- Certifications:BPI, OK Compost
- Shelf Life:10-12 months
Our verdict“This pick fits users who need large, eco-friendly waste bags for outdoor or commercial waste with quick decomposition times.”
ANECO 100% Compostable Waste Bags 2.6 Gallon (110 Count)
This option stands out for those needing a small, eco-friendly bag that fits most 2.6-gallon containers. Compared with larger bags like UNNI’s 13-gallon options, ANECO’s bags are perfect for kitchen scraps or garden waste in limited spaces. Their plant-based cornstarch material ensures full compostability within 6-12 months, a clear advantage over non-compostable alternatives. The extra thick design offers resistance to rips and leaks, making cleanup less messy. However, their limited capacity means they aren’t suited for larger or outdoor waste collection, and they won’t perform well outside of a composting setup without proper facilities. This pick makes the most sense for those with small bins focusing on composting at home or in community gardens, not for general trash collection.
Pros:- Made from fully compostable cornstarch, decomposing in 6-12 months
- Extra thick and resistant to rips and leaks, reducing messes
- Certified for both home and industrial composting standards
Cons:- Limited to 2.6-gallon container size, not suitable for large waste
- Not designed for outdoor storage or long-term outdoor use
Best for: Home composters with small bins needing eco-friendly, space-efficient bags
Not ideal for: People with larger outdoor waste needs or no access to composting facilities
- Capacity:2.6 gallons
- Count:110
- Item Weight:1.7 pounds
- Item Dimensions:16.5 x 16.3 inches
- Material:Cornstarch
- Material Features:Compostable
Our verdict“This compact, plant-based bag suits small-scale composting setups but isn’t ideal for larger or outdoor waste needs.”
UNNI Compostable Bags, 13 Gallon, 200 Count, Extra Thick 0.9 Mil
Compared with ANECO’s smaller bags, UNNI’s 13-gallon bags are designed for larger waste volumes, making them ideal for busy kitchens or office bins. Their plant starch composition is independently certified for compostability, and the extra thickness of 0.9 mil offers enhanced durability against leaks and tears, even with heavier waste. This makes them a strong choice for users who want reliable strength without sacrificing eco-friendliness. However, these bags require access to commercial composting, which isn’t available everywhere, and their recommended use within 9 months might be inconvenient for long-term storage. They are less suitable for small, indoor composting systems or users without composting infrastructure. This makes them better suited for environmentally conscious households handling larger waste loads, where durability and certification matter most.
Pros:- Made with plant-based, compostable materials
- Extra thick at 0.9 mil for reliable durability and leak resistance
- Independently certified for compostability (BPI, CMA, OK compost HOME)
Cons:- Requires access to commercial composting, not always available locally
- Use best within 9 months for optimal performance, which may affect long-term storage
Best for: Larger households or small businesses needing robust, eco-friendly kitchen waste bags
Not ideal for: Individuals with small, indoor compost bins or no access to composting facilities
- Capacity:13 gallons
- Count:200
- Material:Plant starches
- Thickness:0.9 mil
- Dimensions:23.75 in x 31.49 in
- Certifications:BPI, CMA, OK compost HOME
Our verdict“This large, durable compostable bag is ideal for bigger waste loads in settings with proper composting facilities, but less suited for casual or small-scale users.”

Factors to Consider When Choosing Compostable Trash Bags
When selecting compostable trash bags, understanding the key factors can help you avoid common pitfalls and ensure you get the best value. While many options look similar, subtle differences in size, material, and certifications can significantly impact performance and eco-friendliness. Here are the main considerations to keep in mind:Size and Capacity
Matching the bag size to your trash bin is essential to prevent overflows or excessive waste. Common household sizes include 13-gallon and smaller options like 2.6 gallons. Oversized bags can be wasteful, while undersized ones might not contain all waste properly. Always measure your bin before buying to choose a bag that fits well and maximizes eco benefits.
Thickness and Durability
Thicker bags, typically measured in mil (thousandths of an inch), tend to resist tearing and leaks better, especially with heavier or wetter waste. However, increased thickness can also reduce flexibility and increase cost. For general kitchen waste, 0.9 to 1 mil offers a good balance between strength and flexibility, while thinner options might be suitable for lighter waste or small bins.
Certification and Eco-Standards
Genuine compostable bags should carry certifications like ASTM D6400 or BPI. These labels verify that the product has been tested and meets specific standards for biodegradability in commercial composting facilities. Without certification, some products may only be biodegradable in theory or after long periods, which diminishes their eco value. Always check for reputable certifications to ensure environmental impact is minimized.
Cost and Value
Bulk packs often offer better per-bag prices, making them attractive for frequent use. However, larger packs can be less manageable if you only need a few bags at a time. Consider your household size and trash volume when buying in bulk, and weigh the cost savings against storage and usability concerns.
Handling and User Features
Features like drawstrings or handles can make bag removal and disposal easier, especially if you deal with wet or heavy waste. While these features add to the cost, they improve hygiene and convenience. Decide whether such features are worth the extra expense based on your comfort and waste volume.
Frequently Asked Questions
Are compostable trash bags strong enough for heavy or wet waste?
Many compostable trash bags are designed to handle typical household waste, including wet or slightly heavier loads. Thicker options, such as those measuring 0.9 Mil or more, generally provide better tear resistance and leak protection. However, no bag is completely impervious to very wet or heavy waste, so it’s wise to choose a thicker, certified product if you expect to handle such waste regularly.
Can I compost all types of biodegradable trash bags in my home compost bin?
Most certified compostable bags are intended for commercial composting facilities, which operate under specific conditions not always replicable at home. Some bags labeled as compostable may not break down fully in a home compost bin, especially if it’s colder or less aerated. Always check for labels like ASTM D6400 or BPI, and consider whether your home compost setup can meet the conditions needed for proper breakdown.
Do compostable trash bags cost significantly more than regular plastic bags?
Indeed, compostable bags tend to be more expensive per unit than traditional plastic bags due to their eco-friendly materials and certification costs. Bulk purchasing can help offset this difference, but the price premium reflects the environmentally responsible sourcing and biodegradability. If sustainability is a priority, paying a bit more can be justified; otherwise, weigh this against your budget.
How long do compostable trash bags take to decompose?
The decomposition time for compostable bags varies depending on environmental conditions and thickness. Certified bags typically break down within 90 to 180 days in commercial composting facilities. Home composting may take longer and is less predictable, especially if the conditions are not ideal. It’s best to treat these bags as a part of a proper composting process to realize their full eco benefits.
Are there any common mistakes to avoid when choosing compostable trash bags?
One common mistake is assuming all biodegradable or compostable labels are equal — always check for reputable certifications. Another is selecting bags that are too thin or too small for your waste, which can lead to leaks or overflows. Additionally, using compostable bags in regular landfill conditions won’t produce the intended environmental benefits, so it’s important to use them in appropriate composting setups. Proper sizing, certification verification, and understanding the end-of-life process are key.
Conclusion
For those seeking an all-around reliable choice, the UNNI Compostable Bags, 13 Gallon, 50 Count offers a solid balance of strength, size, and eco-certification, making it ideal for most households. Budget-conscious buyers will appreciate the 13 Gallon Compostable Trash Bags (40 Count) for its affordability without sacrificing basic performance. If premium quality and durability are your priorities, the 13 Gallon Compostable Trash Bags Drawstring Heavy Duty 1 Mil stands out. Beginners or those new to compostable products should start with certified, moderate-thickness options to ensure performance without complexity. For specific needs like small kitchen waste or large capacity, select based on size, features, and environmental standards to match your daily routine.”
