Our Picks at a Glance
How To Choose The Best Green Compost Bags
Replacing your plastic liners with compostable ones is a simple switch, but not all green bags perform the same. A few specs make the difference between a bag that stays in one piece and one that turns into a soggy mess halfway to the curb.
Certification Is Everything
A bag labeled “biodegradable” or “eco-friendly” means almost nothing on its own. Look for third-party certification logos: BPI (Biodegradable Products Institute) for commercial composting in the U.S., OK compost HOME by TÜV AUSTRIA if you have a backyard pile, and ASTM D6400 as the standard those certifications rest on. Without these stamps, you cannot be sure the bag will break down in the time and conditions your local facility operates under.
Thickness Measured in Mils
The thickest plastic bags run 0.9 to 1.0 mils, and the same range applies here. A 0.87-mil bag is more prone to tearing at the seam during a heavy load, while a 0.9-mil or 1.0-mil bag handles wet scraps and weekly volume with noticeably fewer failures. Every tenth of a mil matters when you are hauling coffee grounds and melon rinds.
Drawstring vs. Handle Ties
Drawstrings let you cinch the bag shut without touching the contents, a small convenience that matters when the bag is full. Handle-tie bags (the kind with two flaps you knot together) are common on lower-count rolls and are fine for light kitchen waste, but they require a little more effort to close securely. Most owners prefer the drawstring once they have tried both.

In‑Depth Reviews
1. UNNI 13 Gallon Compostable Trash Bags, 50 Count
Our pick — over 4.5★ from 46,500+ verified ratings; the strongest balance of quality and price.
The crowd-favorite 0.9-mil liner that balances thickness, value, and triple certification.
You get 50 bags per roll for a 13-gallon tall kitchen can, each bag measuring 23.75 inches by 31.49 inches. That 0.9-mil thickness (a mil is one-thousandth of an inch) is the balance—noticeably thicker than a typical 0.87-mil bag and tough enough that buyers report “no tearing or leaking” during daily kitchen use. The bags are certified by BPI (Biodegradable Products Institute) under ASTM D6400 (the standard for compostable plastics in industrial facilities), by CMA (Compost Manufacturing Alliance) for field composting, and by OK compost HOME for backyard piles, so you are covered whether you send scraps to a municipal facility or dump them in your own heap.
The trade-off is handling. These bags have no drawstring or handle ties; you gather the open top yourself. That is a minor inconvenience compared to the confidence from a bag that does not split at the seam. A few owners note they tear if you yank them open too aggressively, but the consensus is strong: “Extra thick, strong, no tearing/leaking.” The bag is made from plant-based materials, and the manufacturer recommends storing it in a cool, dry place and using it within nine months for best performance. Skip this pick if you want a bag you can tie shut quickly—you will have to gather the top yourself.
Pros
- Extra thick at 0.9 mil for reliable daily use
- Triple-certified for both commercial and home composting
- 50-count roll stretches further than smaller packs
Cons
- No drawstring or handle ties—you knot the open top yourself
- Seam can tear if you snap the bag open too fast
for heavy loads: Reach for UNNI if you want the certified thickness and the widest composting compatibility without paying for features you do not need.
if few bags: You insist on a drawstring closure—this bag is a simple open-top liner.
2. ecobewus Certified Compostable 13 Gal Bags, 35 Count
Handle ties that hold, plus double certification that covers both the U.S. and Europe.
This 35-count box earns its spot on convenience. The handle ties make closing and carrying a full bin of food scraps much cleaner than wrestling with an open edge. Buyers consistently say the same thing: “Like the handles better than a drawstring bag.” The bags measure 35 by 24 inches, fitting most standard 13-gallon tall kitchen cans, and they carry the BPI certification for ASTM D6400 as well as the OK Compost Home certification from TÜV Austria (a European testing body), meaning they are tested for backyard piles too. If you hate fumbling with an open bag edge, this is the pick for you.
The star-seal bottom distributes weight evenly, so the bag does not split at the base under a moderate load. That said, like all compostable bags, it is vulnerable to very wet scraps. A smart habit is to let wet food waste drain a little before tossing it in. The manufacturer advises storing the bags in a cool, dry, dark place and using them within a year of purchase.
At 35 bags per box, you get fewer per purchase than a 50-count roll, but the handle-tie convenience and strong certification package make this a dependable daily driver. The biggest recurring caution is to avoid overloading the bag with heavy liquids, as the material will start to break down if left too wet for too long.
budget pick: Anyone who hates fumbling with an open-top bag and wants the neatness of handle ties without the cost of a premium brand.
needs durability: Avoid letting extremely wet scraps sit for days—the bag wall can weaken over time with high moisture.
3. ECOLipak 13 Gallon 50 Count Compostable Kitchen Trash Bags
A 50-count roll of surprisingly sturdy PLA bags that earn their praise from real owners.
ECOLipak hits a notable price-per-bag ratio with 50 bags on a single roll, and the owners confirm they hold up. These bags measure 24 by 32.28 inches at 0.87 mil—just a hair thinner than the UNNI 0.9-mil—yet multiple owners describe them as “surprisingly durable” and say they handle everything from food scraps to leaves without tearing. The material is polylactic acid (PLA), a compostable plastic made from corn starch, and it carries both BPI certification for ASTM D6400 and OK Compost Home certification.
The thickness gap is small but worth flagging: at 0.87 mil versus the UNNI’s 0.9 mil, these are about 3% thinner. In practice, the difference is negligible for kitchen scraps, but if you regularly pack the bag to the brim, the thinner seam is a little less forgiving. One owner who uses them for cat litter reports no tearing after a full week. The manufacturer gives these a 10-to-12-month shelf life from the manufacturing date, and they note the bags have a mild scent from the corn materials.
tear resistant: Budget-conscious households that want a 50-bag supply with dual certification and don’t mind an open-top liner.
needs knot: The 0.87-mil wall is thinner than the top pick—fine for standard loads but less ideal for sharp-edged or very heavy waste.
4. AYOTEE Compostable Trash Bags 13 Gallon, 45 Count
The thickest bag in the lineup at 1.18 mils, designed for people tired of wet-bottom failures.
AYOTEE sets itself apart with a thickness of 1.18 mils, noticeably thicker than the 0.87-mil and 0.9-mil options above. That extra heft translates into a star-seal bottom that stays leak-proof under pressure. Owners are clear about this: the bag “held 13 gallons of food/party waste without tearing” and “feels like regular plastic.” The material is Plastarch (PSM), a plant-starch extract, and the bags are certified compostable under ASTM series standards.
The side effect of that thickness is reduced flexibility. The bag is more rigid than thinner PLA bags, meaning you have to be deliberate about fitting it around the rim of your can. A few owners note that the bag feels somewhat “brittle” if you poke it with a sharp object. But for the user who has dealt with one too many leaks from thinner compostable liners, this is the most reliable choice. The 45-count comes as three rolls of 15 bags each, which makes it easy to stash one roll under the sink and keep the others in storage.
green choice: Anyone who prioritizes leak resistance above all else—the 1.18-mil wall is the heaviest in this guide and earns consistent praise for staying intact. If you have had bags split on you before, this is the one to try.
large bins: People who need a more flexible bag that conforms easily to an irregular-shaped can—this one is stiffer.
5. HECTOLIFE 13 Gallon, 50 Count Compostable Trash Bags
A 50-bag drawstring roll that owners say works just like regular plastic but better for the planet.
HECTOLIFE brings a double-layer drawstring to the table, and that detail alone changes the daily experience: you cinch, lift, and go without touching the contents. The bag measures 24 by 30 inches and fits 13-gallon tall bins, with the manufacturer specifying it fits round cans under 15.3 inches in diameter or rectangular cans with a perimeter under 48 inches. The material is plant starch (corn), and the bag carries BPI certification, OK Compost, and Seedling certification from TÜV.
Owners point to the drawstring as the standout feature—it ties securely without snapping off, even when the bag is full. The reinforced claim is the “thickened design” meant to prevent leaks, though a handful of owners note the top can tear slightly when you pull it over the bin rim. The biggest mismatch is fit: some buyers find the bag too loose on their specific can, while others say it is exactly right. Measure your can’s opening before buying to avoid a loose fit.
bulk buy: You want the convenience of a drawstring on a large 50-count roll that is just as tough as standard plastic bags for everyday food waste.
wet trash: The bag is on the looser side for some 13-gallon cans—measure your bin perimeter against the 48-inch spec to be sure.
6. Cleanomic Compostable Trash Bags with Drawstring, 13 Gallon, 25 Count
A smaller-count premium roll that owners describe as silky-smooth and unusually reliable for a compostable bag.
Cleanomic trades higher per-bag cost for a refined user experience. The bag is BPI certified and made with a “silky-smooth” flexible material that feels closer to a traditional plastic liner than the crinkly feel of many plant-starch bags. Owners who tested several options report switching to Cleanomic because it rips less during installation and holds up well against coffee grounds and cat litter. The drawstring closure works reliably, and the bags are fragrance-free and powder-free.
The catch is the 25-count box—you get half the bags of a typical 50-count roll. For a household running a full-size kitchen can, that means buying more frequently. The manufacturer also recommends using the bags within six months of purchase and storing them away from heat and sunlight, a tighter window than the 9-to-12-month shelf life of other brands. Still, for owners who value a bag that behaves like a regular trash bag, “these were so sturdy” is the common refrain.
easy tie: Households that are willing to pay a little more per bag for a smoother, drawstring-friendly experience that feels indistinguishable from plastic.
tight budget: The 25-count means frequent reordering, and the six-month shelf life demands mindful storage.
7. Stout by Envision Compostable Trash Bags, 13 Gallon, 45 Count
The bag that owners describe as the toughest eco option, holding up to a week of diaper use.
Stout walks a different path: the bags are manufactured in America by Envision, a company that provides employment to people who are blind or visually impaired. The durability here stands apart. Owners call them “the best compostable bags” and “5x stronger than Glad,” with the highest focus on durability—that aspect alone earned 153 mentions from buyers. The ASTM D6400 certification means they are engineered for composting in industrial facilities, and the 24-by-30-inch size fits most tall 13-gallon bins.
The toughness comes with a small compromise: the bag is thicker and more brittle than some competitors, meaning it can rip rather than stretch if punctured by a sharp object. A few owners also report that the fit runs slightly small for some cans. But the overwhelming sentiment is that Stout handles heavy, wet loads—diapers, cat litter, full kitchen scraps—without leaking. The mission-driven production is an extra reason to choose it, but the bag earns its spot on performance alone.
strong material: Anyone who needs a bag that survives heavy, wet, or sharp waste and appreciates a product made by an organization employing blind and visually impaired workers.
high volume: The thick material is less forgiving if punctured—avoid loading it with pokey items like broken glass or sharp vegetable stalks.
8. SUPERBIO 13 Gallon Compostable Drawstring Kitchen Waste Bag, 30 Count
A 1.0-mil drawstring bag that carries BPI, Seedling, and OK compost INDUSTRIAL certification.
SUPERBIO hits the 1.0-mil thickness mark, giving it a small but real durability advantage over the 0.9-mil and 0.87-mil options. The 25.2-by-25.6-inch dimensions mean it is slightly shorter in height than many 13-gallon bags, but it still fits most standard tall bins. The drawstring closure is a welcome convenience, and the bag carries BPI certification (commercial composting only), Seedling, and OK compost INDUSTRIAL, so it is fully approved for municipal facilities.
Owners call the bag “leak-proof” and “sturdy,” noting it handles yard waste and kitchen scraps without issue. The manufacturer warns that the bag has a shelf life of about one year and that waste should be emptied within three days when holding organic material with strong acidity. The biggest practical downside is the 30-count roll: you get fewer bags per purchase than a traditional 50-count, and the bag height is a little shorter, meaning it may not cover the rim of a very tall can as generously. If you have a tall kitchen can, check the fit before buying.
wet waste: A 1.0-mil drawstring that meets the strictest industrial composting standards—ideal for households participating in municipal green-waste programs.
sensitive nose: 30 bags per roll is a smaller supply, and the shorter bag height may not fully wrap over the rim of a very deep tall can.
9. HoldOn Compostable Tall Kitchen Drawstring Bags, 13 Gallon, 40 Count
A triple-ply bag built for those who need the ultimate insurance against wet-bottom failure.
HoldOn uses a three-layer construction made from PBAT, PLA, and cornstarch, designed to prevent leaks where most bags fail: the bottom. The 40-count box measures 24 by 27 inches, making these bags slightly shorter than the standard 31-inch height of many competitors. The drawstring is reinforced and “multi-way flex,” and the company is a Certified B Corp, adding a mission-driven angle to the purchase. BPI certification covers the commercial composting standard.
The durability gets strong praise—owners say “this is the bag I needed” and note it “does not split or tear” even with regular kitchen waste. However, the trade-off is that the drawstring ties can snap off if the bag is overloaded, a flaw mentioned by a few long-term buyers. The bag also requires taking out the trash every 2 to 3 days for optimal freshness, which is a faster cadence than some households prefer. At 40 bags per box, the per-bag cost lands in the premium range, but for owners who have had disastrous leaks from other compostable brands, the triple-ply construction justifies the price.
big bins: You have dealt with leaks from other compostable bags and want the strongest multi-layer construction available in a drawstring format.
sharp items: The drawstring tie can break under very heavy loads, and you will need to empty the bag every few days to prevent moisture-related weakening.
Understanding the Specs
Mil Thickness
One mil equals one-thousandth of an inch (0.001 inch). A 0.87-mil bag is thinner and more prone to seam tears; a 1.0-mil or 1.18-mil bag offers noticeably more puncture resistance. This is the single most useful number for predicting whether a bag will survive a full can of wet kitchen scraps. Most standard kitchen bags sit between 0.87 and 1.18 mils.
BPI Certification
The Biodegradable Products Institute tests bags against the ASTM D6400 standard, verifying that at least 90% of the material breaks down into CO2 within 60 days under industrial composting conditions. BPI certification is the gold standard in the U.S. Some bags add OK Compost HOME certification, which tests at lower temperatures for backyard piles. A bag without both may not break down as intended in your local facility.
