Choose the right compostable bag for your kitchen bin
The best compostable trash bags are the ones that fit your kitchen bin, hold everyday food scraps without splitting, and carry certification for the composting system you can actually use.
This guide compares ten compostable trash bags for two common jobs: small countertop food-waste caddies and standard 13-gallon kitchen cans. We look at size, published thickness, closure style, pack count and certification claims. A bag designed for an industrial composting facility is not automatically suitable for a backyard compost pile, so we separate those claims and flag products that need an exact-package check.
- Match bag capacity and dimensions to your bin
- Look for a named third-party compostability certification
- Separate home composting from industrial composting
- Compare closure style, thickness and price per bag
Our Quick Verdict
- Best overall for countertop bins UNNI 2.6-gallon bags combine a useful small-bin size, tie handles and multiple certification claims.
- Best for standard tall kitchen cans UNNI 13-gallon bags offer a 0.9-mil film, 50-count pack and BPI, CMA and OK compost HOME claims.
- Best drawstring pick Simply Bio offers a 1-mil drawstring liner; check the certification on the exact pack and your local collection rules.
- Most important buying check Confirm whether the bag is certified for home or industrial composting. Those labels are not interchangeable.
Prices and stock can change. We use product specifications and certification information rather than claiming to have performed independent tear or leak testing.
How We Selected These Compostable Kitchen Trash Bags
We compared the product information available from Amazon listings, manufacturer pages and certification directories. We did not conduct laboratory strength or composting tests, so we do not present seller performance claims as independently verified results.
We prioritized named third-party schemes and checked the distinction between commercial and home compostability against BPI guidance and product-directory entries.
We separated countertop liners from 13-gallon tall-kitchen bags and checked dimensions where listings supplied them.
Published thickness, drawstring or handle-tie designs, pack count and storage advice were included when available.
We considered pack size and current listed price as a snapshot, but avoided declaring a permanent cheapest option because prices and stock change.
A product being listed by a retailer as compostable is not the same as verifying the exact SKU in a certification directory. Where evidence was incomplete or inconsistent, we say so.

What Does Compostable Actually Mean?
A compostable bag is designed to break down under specified composting conditions. That is different from a vague ‘biodegradable’ claim, which does not by itself tell you how quickly a product breaks down, what conditions it needs or whether it leaves residues.
For buyers, the practical question is not simply whether a bag is called compostable, but where it is certified to compost and whether that system is available to you.
BPI explains that its Commercial Only certification applies to commercial compost facilities, while its Commercial & Home certification covers properly managed home compost bins as well. Its product directory lists certified commercial products; only entries marked ‘Yes’ in the home-certified column have the additional home certification. See the BPI certification explanation and BPI product directory.
In Europe, TÜV Austria’s OK compost INDUSTRIAL and OK compost HOME marks also distinguish the two environments. Do not treat ASTM D6400, BPI commercial certification, EN 13432 or an industrial compost mark as automatic proof of backyard compostability. And even a correctly certified bag may be rejected by a local composting service that does not accept liners.
Compostable vs. Biodegradable Trash Bags
Compostable and biodegradable are not interchangeable labels. A biodegradable trash bag may break down under some conditions, but the word alone does not specify a timeframe, the environment required or whether the material meets a recognized composting standard. A certified compostable bag is assessed against defined requirements for a particular composting environment.
When comparing compostable vs. biodegradable trash bags, look for a named certification and confirm whether it covers industrial or home composting. Do not assume that a bag labelled biodegradable can go into a food-waste collection bin, backyard compost pile or plastic recycling stream.
Best Compostable Trash Bags: 10 Reviews and Picks
These reviews cover the best compostable bags we found for small food-scrap containers and full-size kitchen cans. If you need the best compostable trash bags in a 13-gallon size, start with the full-size options; for countertop caddies, compare the 1.6- and 2.6-gallon liners. We also distinguish home-compostable products from bags intended only for industrial facilities.
1. UNNI 2.6-Gallon Compostable Bags — Best Overall for Countertop Bins
01
The strongest all-round small-bin choice in this group because the size, handle-tie closure and certification claims are clearly stated.
Best for: People with a 2.6-gallon countertop compost pail who want a tie-handle liner.
UNNI’s 2. 6-gallon bag is designed for countertop food-scrap bins rather than full-size kitchen garbage cans. The listing gives dimensions of 16. 3 × 22 inches and a thickness of 0. 68 mil, with 50 bags on a roll.
That makes it a practical size for collecting fruit and vegetable peels, coffee grounds, eggshells and similar scraps before taking them to a compost collection point. The handle-tie top is useful because you can knot the bag without trying to twist the thin film into a tight neck.
The product listing identifies BPI, CMA and TÜV Austria OK compost HOME certifications. BPI explains that its commercial and home programs are separate certification schemes, so the home mark is particularly relevant if you plan to compost in a properly managed backyard system.
Check the mark on the actual package and local acceptance before buying. This is a liner for a small food-scrap caddy; don’t judge it against thick 13-gallon bags intended for heavier loads.
- 50 bags per roll
- Tie handles make the bag easy to close and carry
- Listing identifies BPI, CMA and OK compost HOME certifications
- Published size is 16.3 × 22 inches
- 0.68-mil film is not the thickest option in this roundup
- A small caddy bag is not a replacement for a 13-gallon kitchen liner
The strongest all-round small-bin choice in this group because the size, handle-tie closure and certification claims are clearly stated. For most countertop caddies, this is where I would start.
2. ANECO 2.6-Gallon Compostable Bags — Best Value Small-Bin Pack
02
A quantity-focused pick for small compost pails, provided the current 110-count pack and certification marks match the listing.
Best for: People who empty a 2.6-gallon countertop pail often and want a higher-count pack.
ANECO’s 2. 6-gallon bags stand out mainly for their pack count: the current Amazon listing describes 110 bags, including 10 bonus bags. The listed dimensions are 16. 5 × 16. 3 inches, which places the product in the countertop-caddy category.
That higher count can be useful if you empty your small food-scrap bin frequently and go through liners quickly. The listing claims home compostability and names ASTM D6400, BPI and OK compost HOME among its credentials.
Because retailer descriptions can change and certification applies to particular products, check the certification logos and product details on the current package rather than relying on broad ‘100% compostable’ wording alone.
The listing also does not provide a clear mil thickness in the details reviewed, so I would not rank it as the strongest bag on the basis of seller language. Its appeal is the combination of a familiar 2. 6-gallon size and a larger pack.
- 110 bags listed in the current pack
- Sized for 2.6-gallon countertop bins
- Retailer listing states home and industrial compostability claims
- Flat-top design is simple to fit over a small caddy
- Certification claims should be checked against the exact pack
- No published thickness figure was supplied in the product details reviewed
A quantity-focused pick for small compost pails, provided the current 110-count pack and certification marks match the listing. Before ordering, match the exact size and certification to your bin and composting setup.
3. SUPERBIO 1.6-Gallon Compostable Food-Scrap Bags — Best for Very Small Caddies
03
Choose this only when your caddy is genuinely small; the 1.6-gallon size is its main advantage.
Best for: Compact countertop pails, under-sink food-scrap containers and households that empty scraps frequently.
SUPERBIO’s 1. 6-gallon bags are made for compact food-scrap containers. The product details list a 6-liter capacity, dimensions of 16. 1 × 19. 3 inches and a 0. 63-mil thickness, with 50 bags per roll. A handle-tie top makes it easier to close the liner before carrying scraps to an outdoor bin or organics collection point.
The product description identifies BPI and OK compost HOME marks, but certification wording can be confusing: BPI’s commercial certification and home-compostability certification are separate.
Check the exact logos and certification information printed on the current product rather than assuming one mark covers both environments. This bag earns its place because some kitchen caddies are too small for a 2. 6-gallon liner. If your bin is a standard countertop size, the UNNI or ANECO 2.
6-gallon options will usually be a more sensible starting point.
- Compact 1.6-gallon capacity
- 50 bags per roll
- Handle-tie closure
- Listing specifies 0.63-mil thickness and 16.1 × 19.3-inch dimensions
- Too small for many countertop bins designed around 2.6-gallon liners
- The listing’s BPI and home-compost claims should be checked separately on the package
Choose this only when your caddy is genuinely small; the 1.6-gallon size is its main advantage. Before ordering, match the exact size and certification to your bin and composting setup.
4. UNNI 13-Gallon Compostable Kitchen Bags — Best Tall Kitchen Bag
04
The best-balanced full-size pick in this roundup: standard capacity, stated thickness and a broad set of certification claims.
Best for: Households with a standard 13-gallon kitchen can that want a product with multiple certification claims.
UNNI’s 13-gallon bag is the most straightforward recommendation for a standard tall kitchen can. The listing specifies a 49. 2-liter capacity, dimensions of 23. 75 × 31. 49 inches and a 0. 9-mil thickness. Each roll contains 50 bags.
Those details make it easier to check whether the liner will fit your can before ordering, and the thickness figure provides a more useful comparison point than an unsupported ‘heavy-duty’ label. UNNI identifies BPI, CMA and TÜV Austria OK compost HOME certifications for this product.
Its own product page also lists the dimensions, pack size and storage guidance. The flat-top format is simple, but it does not have the convenience of a drawstring when you want to close a full bag quickly. Store the roll in a cool, dry place and use it within the manufacturer’s recommended period.
If you want one full-size compostable bag to start with, this is the strongest all-round option in the current shortlist.
- Standard 13-gallon / 49.2-liter capacity
- 0.9-mil thickness and 23.75 × 31.49-inch dimensions
- 50 bags per roll
- Listing identifies BPI, CMA and OK compost HOME certifications
- Flat-top closure may be less convenient than a drawstring
- Compostable liners should be used and stored according to the stated shelf life
The best-balanced full-size pick in this roundup: standard capacity, stated thickness and a broad set of certification claims. For a standard 13-gallon kitchen can, this is the most balanced pick in the roundup.
5. SUPERBIO 13-Gallon Compostable Drawstring Bags — Best Industrial-Compostable Drawstring
05
A useful full-size drawstring option, but its industrial-composting limitation should be made clear.
Best for: People whose local commercial composting service accepts certified industrial-compostable liners and who prefer a drawstring.
SUPERBIO’s 13-gallon drawstring bags are a good match for readers who prefer a drawstring closure and have access to a commercial composting program that accepts liners. The listing specifies a 1-mil film, a 49. 2-liter capacity, dimensions of 25. 2 × 25. 6 inches and 30 bags per roll.
It identifies BPI commercial compostability and TÜV Austria OK compost INDUSTRIAL, alongside the Seedling mark and ASTM D6400 / EN 13432 standards. Those are industrial-composting claims; do not treat them as proof of backyard compostability.
The shorter height shown in the listing compared with some 13-gallon bags also makes it especially important to compare the dimensions with your bin before ordering.
This is a more specialized recommendation than UNNI: choose it for the closure style and the composting system you actually use, not simply because the title says ‘compostable’.
- 13-gallon / 49.2-liter capacity
- 1-mil thickness and 25.2 × 25.6-inch dimensions listed
- Drawstring closure
- 30 bags per roll
- The listing identifies BPI and OK compost INDUSTRIAL, not a home-compost certification
- Confirm local facility acceptance before using it for organics collection
A useful full-size drawstring option, but its industrial-composting limitation should be made clear. Before ordering, match the exact size and certification to your bin and composting setup.
6. Simply Bio 13-Gallon Compostable Drawstring Bags — Best Thicker Drawstring Option
06
A strong feature set on paper: 1-mil film, drawstring closure and a standard tall-kitchen capacity.
Best for: People who want a 13-gallon drawstring bag and value a published 1-mil thickness.
Simply Bio combines three features many shoppers look for in a tall kitchen liner: 13-gallon capacity, a drawstring closure and a stated 1-mil thickness. The listing gives dimensions of 23. 7 × 29. 4 inches and 30 bags per roll.
A drawstring is convenient when lifting and tying off a full bag, while the published thickness gives buyers a measurable point of comparison. The product listing names BPI, ASTM D6400, TÜV Austria OK compost HOME and OK compost INDUSTRIAL certifications.
As with all compostable liners, check the exact certification marks on the pack and confirm that the collection facility accepts them. The 30-count pack is smaller than UNNI’s 50-count option, so the price per bag matters more than the headline package price.
Simply Bio makes the most sense when drawstring convenience and the thicker listed film matter more to you than buying the largest pack.
- 13-gallon / 49.2-liter capacity
- 1-mil thickness
- Drawstring closure
- 30 bags per roll; dimensions listed as 23.7 × 29.4 inches
- Smaller pack than 50-count alternatives
- The listing’s multiple certification claims should be checked against the exact packaging
A strong feature set on paper: 1-mil film, drawstring closure and a standard tall-kitchen capacity. Before ordering, match the exact size and certification to your bin and composting setup.
7. Compostic 13-Gallon Compostable Kitchen Bags — Best Home-Composting Claim to Verify
07
A potentially useful option, but its home-compost claim needs careful SKU-level verification.
Best for: Shoppers interested in home-compostable bags who are willing to check the exact third-party certification on the pack.
Compostic’s 13-gallon starter pack is listed as 50 bags sized for standard tall kitchen bins. The retailer description calls the bags home compostable and plant-based.
There is also a useful certification distinction worth spelling out: BPI’s online product directory lists Compostic’s USRB13GL50PK 13-gallon 50-pack under commercial compostable kitchen food-scrap bags, but the directory does not mark that entry as home-certified.
That does not settle every other certification claim the manufacturer may make, but it means readers should look for the actual DIN CERTCO or other home-compostability certificate on the specific package before putting these bags in a backyard pile.
If you use a municipal or commercial organics program, check that it accepts this product. Compostic is worth considering, but I would not repeat the listing’s broad home-compostable language without that qualification.
- Standard 13-gallon size
- 50 bags in the listed starter pack
- Product listing describes the bags as plant-based and home compostable
- BPI directory lists the Compostic USRB13GL50PK 13-gallon 50-pack for commercial compostability
- The BPI directory entry does not show this SKU as home-certified
- The retailer’s home-compost claim should not be confused with the BPI commercial certification
A potentially useful option, but its home-compost claim needs careful SKU-level verification. Before ordering, match the exact size and certification to your bin and composting setup.
8. OrangeBio 13-Gallon Compostable Trash Bags — Best Documented Home-Compost Option
08
One of the clearest home-compost options in this list because the brand publishes the certification claim on its own product page.
Best for: Shoppers who specifically want a 13-gallon liner with a stated home-compostability certification.
OrangeBio’s 13-gallon bags are designed for standard tall kitchen cans and food-scrap collection. The product details specify 24 × 31. 5-inch dimensions, a 0. 9-mil thickness and a 50-count pack.
Most importantly, OrangeBio’s own product page identifies BPI certification and TÜV Austria OK compost HOME and INDUSTRIAL credentials for this product. That gives readers a more direct manufacturer source for the home-compostability claim than a generic retailer phrase.
The Amazon listing showed limited stock when checked, so availability may change; compare the brand’s direct listing with Amazon before ordering. Even with a home-certified bag, follow the composting instructions and avoid assuming that every backyard pile has ideal conditions.
OrangeBio is the most clearly documented option here for readers who specifically want a tall kitchen bag that carries both home and industrial compostability claims.
- 13-gallon capacity and 24 × 31.5-inch dimensions
- 0.9-mil thickness
- 50 bags per pack
- OrangeBio’s product page identifies BPI and TÜV Austria OK compost HOME and INDUSTRIAL certifications
- The Amazon listing showed limited stock at the time checked
- Check current price and stock before deciding
One of the clearest home-compost options in this list because the brand publishes the certification claim on its own product page. Before ordering, match the exact size and certification to your bin and composting setup.
9. BioBag 13-Gallon Compostable Tall Kitchen Bags — Best Established Brand
09
A credible brand-led option, especially for shoppers who value a specialist organic-waste product maker.
Best for: Shoppers who prefer a specialist compostable-bag brand for collecting kitchen food waste.
BioBag is a long-established specialist in bags and films for collecting organic waste. The Amazon listing for this 13-gallon product identifies BPI certification and ASTM D6400 compliance, and the pack contains 48 bags arranged as four rolls of 12.
BioBag’s own certification page explains the standards and certifying bodies used across its range, including ASTM D6400, EN 13432, BPI and TÜV Austria. However, certifications can vary by individual bag and SKU, so check the packaging for the exact product you receive rather than assuming every BioBag liner is home certified.
This product is a reasonable choice for shoppers who prefer an established compostable-bag brand and want a tall-kitchen format. Its 48-count pack is slightly smaller than the UNNI and OrangeBio 50-count options, so compare price per bag before deciding.
- 13-gallon tall-kitchen format
- 48 bags total across four rolls of 12
- Product listing identifies BPI certification and ASTM D6400
- BioBag publishes a dedicated certifications page
- Pack count is lower than 50-count alternatives
- Exact pack and certification should be checked before assuming home compostability
A credible brand-led option, especially for shoppers who value a specialist organic-waste product maker. Before ordering, match the exact size and certification to your bin and composting setup.
10. If You Care 13-Gallon Certified Compostable Tall Kitchen Bags — Best Simple Certified Food-Scrap Bag
10
A small, simple option with a BPI commercial listing; it is not the pick for backyard composting.
Best for: People who want a small pack of a recognizable compostable food-scrap bag for a tall kitchen bin.
If You Care’s 13-gallon tall kitchen bags are a compact pack option for readers who do not need 30 or 50 liners at once. The Amazon listing identifies a 12-count pack for food scraps and kitchen waste. BPI’s online catalog lists If You Care SKU J25065 as a certified 13-gallon compostable tall kitchen bag.
The catalog’s home-certification column is blank for this product, so it should be treated as a commercial-composting option rather than a backyard-compostable liner.
That is an important distinction: BPI states that its catalog lists commercially compostable products, and only entries marked in the home-certified column have that additional certification.
The small pack is convenient for occasional use or trying the product, but the cost per bag may be high compared with 30-, 48- or 50-count rolls.
- 13-gallon tall-kitchen capacity
- 12 bags per pack
- BPI’s directory lists If You Care SKU J25065 as a certified kitchen food-waste bag
- Straightforward choice for occasional food-scrap collection
- Only 12 bags per pack
- BPI directory does not mark this SKU as home-certified
- Not the best value for households that use liners daily
A small, simple option with a BPI commercial listing; it is not the pick for backyard composting. Before ordering, match the exact size and certification to your bin and composting setup.
What to Look for in Compostable Kitchen Trash Bags
This is the most important distinction. BPI’s catalog lists commercially compostable items; a separate home-compostability mark or certification is needed for backyard composting.
Gallon capacity is useful, but dimensions determine whether the bag reaches over the rim and leaves enough room to tie or close.
Flat-top, handle-tie and drawstring bags have different advantages. A tie handle is easy to knot; a drawstring can be more convenient on a full-size can.
A published mil measurement can help compare bags, but it does not prove puncture or leak performance by itself.
Compostable films can be more sensitive to heat, moisture and long storage than conventional plastic liners.
A certified bag may still be rejected by a municipal or commercial composting program.
How to Choose the Right Bag Size
1.6 to 2.6 gallons — countertop compost pails
Small compostable bags are designed for fruit and vegetable scraps, coffee grounds, eggshells and other food waste before emptying the caddy. A 1-gallon compost bag may suit a very compact pail, while 1.6- to 2.6-gallon liners fit many common countertop bins. Check actual width and height because bags with the same stated capacity can fit very differently.
13 gallons — standard tall kitchen cans
A 13-gallon liner is a common size for a full-height kitchen can, while an 8-gallon compostable bag may be a better match for a smaller kitchen bin. Match dimensions to the can and leave enough overhang to close the liner without stretching the film. Capacity alone does not tell you whether the bag will fit.
Larger bags are not automatically better
Thirty-gallon and larger compostable liners are often intended for yard waste, commercial bins or oversized containers. They are not automatically suitable replacements for a standard kitchen bag. This guide focuses on kitchen sizes rather than oversized yard-waste bags.
If you are searching for the strongest compostable trash bags or heavy-duty compostable trash bags, compare the published film thickness, dimensions and bottom construction. A higher mil number can be a useful specification, but it does not prove puncture resistance or leak performance. We have not independently lab-tested these bags, so we do not label any option the strongest based on an unverified claim.
Tips for Using and Storing Compostable Bags
- Store unused rolls in a cool, dry place away from direct sunlight, heat and moisture.
- Buy only the quantity you can use within the shelf life stated by the manufacturer.
- Avoid leaving wet food scraps sitting in a liner for several days; follow the product’s instructions for maximum storage time.
- Do not overfill the bag or drag it across sharp edges. Compostable films can be more sensitive to punctures than conventional plastic.
- Check whether your local composting program accepts certified liners before putting one in the organics cart.
- Never put compostable plastic bags in conventional plastic recycling unless your local program explicitly instructs you to do so.
Are Compostable Bags Better Than Regular Plastic Trash Bags?
They can be a better fit when your household separates food scraps and has access to a composting system that accepts the specific bag. In that situation, a certified liner can make food-scrap collection cleaner and more convenient. But a compostable bag sent to landfill does not deliver the same benefit as one accepted and processed by an appropriate composting facility.
Conventional plastic bags may be stronger, cheaper and more widely accepted for ordinary trash collection. Compostable liners can cost more, need careful storage and may be rejected by some compost programs. The environmental advantage therefore depends on the full disposal route, not just the material claim printed on the roll.
Where to Buy Compostable Kitchen Trash Bags
Amazon has a broad selection of compostable trash bags, including small food-waste liners and 13-gallon tall kitchen bags. When comparing compostable trash bags on Amazon, check the exact size, pack count, current price per bag and certification marks rather than relying on the listing title alone. Prices, stock and product descriptions can change.
For brands such as UNNI, OrangeBio and BioBag, the manufacturer’s certification page can help clarify which claims apply to the product family; still check the exact SKU on the package.
Frequently Asked Questions
Compostable Kitchen Trash Bags FAQs
Are compostable kitchen trash bags actually compostable?
They can be, when the exact product has a recognized certification and is processed under the conditions that certification requires. Check the certification and local facility rules; the word ‘compostable’ alone is not enough.
What is the difference between home-compostable and industrial-compostable bags?
Industrial composting uses controlled conditions and higher temperatures. Home-compostable certification is tested for the lower and more variable conditions of a properly managed backyard compost system. A commercial certification does not automatically cover home composting.
Can I put BPI-certified bags in my backyard compost?
Only if the exact product also carries a home-compostability certification. BPI distinguishes Commercial Only from Commercial & Home certification, and its product directory marks home-certified items separately.
What size compostable bag fits a kitchen trash can?
A standard tall kitchen can commonly uses a 13-gallon bag. Countertop food-scrap pails usually need a 1.6- to 3-gallon liner. Check dimensions as well as capacity.
Are compostable bags leakproof?
No bag should be assumed completely leakproof. Thickness, bottom seals, how wet the scraps are and how long waste sits in the bag all affect performance. Avoid overfilling and follow the manufacturer’s storage instructions.
Can compostable bags go in the recycling bin?
Generally no. Compostable liners can contaminate conventional plastic recycling. Use the organics stream only when your local program accepts that exact type of liner.
Do compostable bags break down in a landfill?
Not necessarily. Many compostable products are designed for aerobic composting conditions, not the low-oxygen environment of a landfill. Their intended benefit depends on being collected and processed by an appropriate composting system.
How should I store compostable trash bags?
Keep them in a cool, dry place away from heat, moisture and direct sunlight. Check the manufacturer’s shelf-life guidance and avoid buying more rolls than you can use within that period.
What are the best compostable trash bags for kitchen use?
For small countertop food-waste caddies, UNNI’s 2.6-gallon bags are the best all-round pick in this roundup. For a standard 13-gallon kitchen can, start with UNNI’s tall kitchen bags. Choose a product with a home-compostability certification if you plan to compost it at home, and check local acceptance first.
Which Compostable Kitchen Trash Bags Should You Buy?
- For a countertop compost caddy, start with UNNI 2.6-gallon bags; choose SUPERBIO 1.6-gallon only if your bin is especially small.
- For a standard tall kitchen can, UNNI 13-gallon is the most balanced pick in this comparison.
- If you prefer a drawstring, compare Simply Bio and SUPERBIO, but pay attention to whether the certification is home or industrial.
- If backyard composting is your goal, look for a home-compostability certification on the exact SKU and confirm the bag suits your setup.
There is no single compostable liner that is best for every kitchen. The right bag is the one that fits your bin, performs adequately for the waste you collect and is certified for the composting environment you can actually use. Check the exact package, store it properly and follow your local composting rules.
