Best Disposable Compost Bags of 2025

"I absolutely love these bags! Good quality and great quantity! I've been using them for a couple of years now. They fit perfectly in my small compost container next to my sink, and I use them for disposing of old cooking oil after it cools down. No spills at all!"

"I've ordered these bags multiple times for my small compost pail, and I'm very pleased with the size and quality. I appreciate that they are compostable. I would have given them 5 stars, but I occasionally experience leaks. I always place a couple of paper towels at the bottom of the pail to keep it clean, then I put both the paper towels and the full bag into the compost bin."

"These bags are a game changer for my kitchen! I haven’t had any trouble with little flying bugs since I started using them for food scraps. Good quality with great thickness—I’m really impressed!"

"I've been using these bags for several years and have been very satisfied. They do take a little longer to degrade in a backyard compost bin, but I figure that's a reasonable compromise. My most recent order was clearly defective: the bags were a darker color, and they would split the entire length of the bag just by pulling them out of the box. I contacted the company, and a rep got back to me within 20 minutes. She suggested I check the date on the bags, and explained that they've had problems with expired bags being sold even through the “BioBag Store.” Sure enough, the date on the bags was 2020! She FedEx-ed me a new box (dated 2024) and these bags are fine. If you get a bad batch, check the manufacturing date! I do recommend these bags."

"I like these compost bags. They fit my little container perfectly. I can literally just throw the entire bag into the compost. The downside is that they aren't super sturdy. If my compost builds up too much liquid before I take it out, a hole opens up and everything falls through when I'm trying to pick it up."

"I learned that the Amazon fulfillment sent me bags made 5 years ago in 2019, so they were beyond the expiration date. After placing a new order and checking the date, the bag was great! It held well with about 12 gallons of dog poop that was heavy to lift into the trash can. Be sure to check the date right after receipt and return them if not within the last year. I want to love these, but they fail with almost every use - even bagging fluffy shredded paper! Don't waste your money!"

"These bags fit perfectly in my bathroom trash cans. They are not thin and have never torn. I’ve used them for the last 3 months without any leaks. There’s no drawstring, but I can easily tie the handles together. I would highly recommend these trash bags."

"I use these bags for my daily coffee grounds and other kitchen scraps, transferring them to my outdoor composter. They hide any smells and are very sturdy. I toss in some compost starter, add scraps throughout the week, and then start again. They are perfect for my needs."

"These bags fit just right in my little compost bin. I find them very convenient with the handles. They’re sturdy enough for my needs, but they might leak if there are liquids inside. I’ve purchased them multiple times and I’m quite satisfied."

"I mistakenly ordered the 2.6 gallon size for my 3 gallon mini-bin. Since I couldn’t return them, I donated them to Goodwill. I absolutely love the 3 gallon size; it makes disposal quick, neat, and easy. However, I have to be cautious with sharp flower stems, as the bags can be easily pierced. For most compostable waste, they work fine, but I double bag to avoid any mess."

"I live in Brooklyn and received a countertop bin for composting from DSNY. These bags fit my countertop bin perfectly. I had food scraps in the bag for about 4 days, and it held up without deteriorating. This is a great value and the size is just right. Now, I need to find the right size for my curbside bin!"

"I have this product on subscription, and while the quality has been inconsistent, I have experienced both great and weaker bags. The first box was excellent, while the second was flimsier and sometimes leaked. The third delivery was back to being leak-proof and of good quality. I’ll wait for my fourth delivery to decide if I’ll keep the subscription."

"After switching to this bag, I noticed a huge difference! No more leaks or tears; it's sturdy and dependable for my kitchen scraps."

"I use these bags for my biodegradable cat litter, and they hold up really well. I'm surprised by their strength, and I feel better about using them instead of regular plastic bags."

"I've been using these bags for years now and they are my first choice for composting. They break down quickly and keep my compost bucket cleaner."

"I've been using UNNI compostable bags for my kitchen food scraps and yard waste for a few months, and I'm very satisfied with their quality and performance. They are easy to use, fit well in my small kitchen trash can, and have a convenient handle. I've had no issues with tearing or leaking, and they help reduce moisture and mold in my compost pile. I highly recommend them!"

"Previously, I struggled with bags that tore at the bottom whenever I tried to pull them out. Now, with the UNNI bags, I have no issues at all. I definitely recommend them!"

"Overall, I'm pleased with these bags. However, my last order arrived in a mailer covered in fabric softener, which made me feel sick. It's been an issue with many shipments, and I hope it gets resolved."

"I've been using these compostable bags for years, and I really like them. They fit perfectly in my bedroom and bathroom garbage pails, and they've always proven to be very sturdy. It's great knowing they are compostable, and I plan to keep using them."

"These liner bags are ideal for kitchen compost bins. The extra thick material ensures there are no leaks, and they break down efficiently, making them an eco-friendly choice. I highly recommend them for anyone wanting to reduce their environmental impact without compromising on quality."

"I find these bags work perfectly for my small trash can in the bathroom and my kitchen compost. I regularly use baby wipes and have experienced no leaks so far. I change the bag weekly, and my compost bin in the freezer has held up for two weeks without any issues. Great price and product! The only downside is they can be a bit hard to tear off."

"After using BioBag bags for years, I decided to try these and was pleasantly surprised. They perform similarly, but I love how much smaller the box is and how easy they are to dispense. They hold up well in my compost bin, even with wet contents. So far, I haven't found a compostable bag that doesn't sweat, but I'm happy with these as long as the price stays competitive."

"I'm really impressed with the strength of these bags. I use the 3-gallon size for cat litter and other purposes. There was one time a bag ripped when I was holding it by just a couple of fingers, but overall, they handle the weight well. I wish they were a bit thicker, but the current thickness seems to balance price and performance effectively."

"I absolutely love these bags! I've started using them in my small bathroom trash cans, and they've performed wonderfully. I was worried about them breaking down in a humid environment, but they didn't. I also make sure not to add anything wet to them. Highly recommend!"

“I ordered these due to the mandatory compost law in NYC. They seal well, have no odor, and fit perfectly under my sink.”

“I find it hard to locate biobags for recycling food waste, but these bags are perfect for a single person or couple—not too large at all.”

“While they are smaller than I expected, they work great for my cat litter bin.”

"I really enjoy the soft feel of this bag, and it's the perfect size I was looking for. I appreciate the extra thickness, making it sturdy enough to carry from my kitchen to the outside waste can without breaking or tearing."

"This is my second order of these bags; they hold up well and are a great size for my kitchen counter scraps container. I'm quite satisfied with their performance."

"I was thrilled to find compostable bags since I dislike plastic and want to do better for the environment. However, I encountered an issue where several bags were sealed at the bottom, preventing me from using them fully. While the first few worked fine, it was disappointing to face quality issues with the rest. Still, I believe I can manage with them since they're soft and flimsy."
