The best compostable trash bag is the one that fits your bin, holds the waste you collect, and matches the composting system that will receive it. A small food-scrap liner, a 13-gallon kitchen bag and a liner for a commercial wheeled bin have different jobs. No single brand or thickness is the best choice for all three.
This guide helps you compare published products, then turn that comparison into a workable specification. You will find examples for small caddies, kitchen bins and larger organics programs, followed by the checks that matter when you buy in bulk.
Buying for a business? If you source bags for a retail brand, distribution range, commercial site or organics collection program, you may need a size, seal, roll format or carton configuration that a retail product cannot provide. ORIZON offers affordable compostable trash bags tailored for business buyers; we do not currently accept individual retail orders.
Quick Answer: Best Compostable Trash Bags Brand
| Your use case | Published product worth examining | Why it is a useful reference | What you still need to check |
|---|---|---|---|
| Small countertop food-scrap caddy | UNNI 2.6-gallon food-scrap bag | The product page publishes its capacity, thickness and compostability information. | Your caddy’s actual dimensions, current certification listing and collection rules. |
| Standard tall kitchen bin where home composting is required | Green Earth 13-gallon bag | Its product page publishes dimensions and home-compost information. | The exact product’s current certification and whether its shape and closure suit your bin. |
| Tall kitchen bin using an accepted commercial composting route | HoldOn 13-gallon drawstring bag | The published format combines a 13-gallon size with a drawstring and industrial-compostability information. | Local facility acceptance; the industrial claim does not establish home-compost suitability. |
| Commercial kitchen or institutional food-waste collection | BioBag 13-gallon liner | The published bulk format has a straight top and star-sealed bottom. | The current item specification, case pack, required certification and receiving facility. |
| Larger commercial bin | EcoSafe 33 × 39-inch liner | The product page gives a specific SKU, thickness, roll count and case quantity. | Fit with your actual bin, facility acceptance and the exact product documentation. |
These are published product examples, not laboratory-tested winners. Use them to identify the format and documentation you need. ORIZON has not independently tested every product above under the same tensile, puncture, leak or load conditions.
If you are developing your own range, compare the specification behind each product before asking a manufacturer to reproduce a retail bag’s appearance.
Start With the Waste Stream, Then Choose the Bag
A bag may fit a container perfectly and still be the wrong choice if the receiving program does not accept it. Before you compare brands, establish where the filled bag will go.
For a kitchen food-scrap caddy, you need to know how wet the scraps become and how often the bag is removed. For a restaurant or institutional kitchen, you also need to consider the load during lifting and transfer. For a municipal program, the hauler and receiving facility may have their own requirements for bags, labels and acceptable materials.
Ask these three questions first:
- What waste will the bag collect?
- Will the filled bag enter home composting, an accepting commercial composting facility, or ordinary trash?
- Has the receiving hauler or facility confirmed that it accepts this type of liner?
A compostability certificate does not replace the third question. Collection rules vary, and the US EPA advises you to check whether your local program accepts compostable plastic.
How to Choose a Compostable Bag That Fits and Holds Up
Measure the bin rather than relying on its capacity
Two bins marked “13 gallons” or “120 L” may have different openings and heights. Measure the opening, bin height and the amount of bag you want to fold over the rim. If your bin is rectangular or unusually narrow, send its dimensions or a photograph when requesting a custom liner.
For a 3-gallon food-scrap caddy, pay particular attention to the opening and usable bag length. A stated capacity tells you how much the bag can contain; it does not guarantee that the bag will stay in place on your caddy.
Match the construction to your handling method
A flat-top liner may suit a collection bin emptied with the container. A handle-tie or drawstring can make closing and carrying more convenient. A star-sealed bottom may be useful for some round bins and wet organic waste, while another construction may fit your container better.
Your sample test should reflect what people actually do: fill the bag with the intended waste, leave it for the expected holding period, remove it from the real bin, and carry it using the planned method.
Treat thickness as one specification, not a strength score
A thicker film is not automatically the most durable finished bag. Dimensions, formulation, seal quality, closure and load distribution also affect how it performs. Wet scraps, sharp stems and a long holding period can reveal problems that a dry, empty-bag inspection will miss.
If a supplier describes a bag as “heavy duty,” ask what load and handling conditions support that claim. When you compare two suppliers, test samples under the same conditions rather than relying on unrelated marketing descriptions.
Plan storage around your consumption rate
Ask for storage guidance for the specific product you intend to buy. Heat, moisture and long storage periods can matter when you purchase many months of stock at once. Your order quantity should reflect how quickly your customers or collection program will use the bags, not only the lowest available unit price.
Difference Between Home Compostable and Industrial Compostable Requirements
If your customers will put the bag in a backyard compost pile, check for home-compost certification covering the exact finished product. A product described only as commercially or industrially compostable should not be presented as suitable for home composting.
In the US, BPI’s product directory identifies certified items individually. Its listings distinguish commercial compostability from products that also carry a home-compost designation. Elsewhere, certification schemes and applicable requirements differ by market. Check the current certificate and its product scope before placing a mark on a custom bag.
If your customers use curbside collection, ask the hauler or composting facility what it accepts. A home-compost designation does not automatically override a collection program’s rules. Likewise, a commercially certified bag is not a claim that the bag will compost in landfill.
For a custom project, certification availability depends on the applicable current certificate and your final finished-bag specification. Dimensions, thickness, colour, printing and other changes need to be reviewed before you make a product claim or use a conformity mark. You can review ORIZON’s company and certification information as part of that discussion.
Best 2.6- to 3-Gallon Compostable Trash Bags for Food Waste
For countertop compost bins and small kitchen food-scrap caddies, 2.6- to 3-gallon bags are usually the most practical size range. Among the products reviewed here, UNNI is a strong choice for buyers looking for a documented 2.6-gallon option, while Green Earth stands out when a true 3-gallon size is preferred. Glad is relevant for municipal or commercial composting applications where the specific product is accepted, while EcoSafe offers another program-oriented food-scrap liner option.
Do not choose only by stated gallon capacity. Actual width, length, thickness and caddy shape can differ between brands, so measure the bin before buying.
| Product | Published size and construction | Published composting information | Best use and what to check |
|---|---|---|---|
| UNNI 2.6 Gallon Small Food Scrap Waste Bags | 2.6 gal / 9.84 L; 0.71 mil; 100-bag option published | BPI/ASTM D6400, OK compost HOME and CMA information published | Good documented option for countertop food-scrap bins. Check the caddy dimensions and storage period. |
| Glad Certified Compostable Bags, Small 10 Litres | 10 L / approximately 2.6 gal; 20 bags; thickness not clearly shown | ASTM D6400; BPI and BNQ certification information published for municipal composting | Mainstream small-bin option. Do not assume it is home compostable; check local program acceptance. |
| Green Earth 3 Gallon Compostable Trash Bags | 3 gal; 16.9 × 17.7 in; 0.71 mil; 100 bags per roll | BPI/ASTM D6400 and OK compost HOME information published | Useful where a true 3-gallon size and published home/commercial scope are required. |
| EcoSafe Small Food Scraps Bag, product CBR1617-6 | 2.5 gal / 9.5 L; 16 × 17 in; 0.6 mil; easy-tie format published | EcoSafe states its compostable liners are BPI certified and CMA approved | Suited to residential or program-based food-scrap collection. Verify the current product sheet and case format. |
When selecting compostable food-waste bags, measure the caddy opening and height, consider how long wet scraps will remain in the liner, and confirm whether the bag will enter home or commercial composting. Sharp scraps such as bones and stems can also affect performance.
Best 12- to 13-Gallon Compostable Kitchen Trash Bags
Standard tall kitchen bins commonly use 12- to 13-gallon liners, but capacity alone does not guarantee fit.
| Product | Published size and construction | Published composting information | Best use and what to check |
|---|---|---|---|
| BioBag 13 Gallon Compostable Liner, item 13G2229 | 13 gal; straight top and star-sealed bottom; verify the current technical sheet for dimensions and thickness | Certified-compostable product information published | Commercial kitchens, food service and institutional organic-waste collection. Confirm facility acceptance and case format. |
| Green Earth 13 Gallon Compostable Trash Bags | 13 gal; 23.75 × 29.375 in; 1 mil; 50 bags per roll | BPI/ASTM D6400 and OK compost HOME information published | Standard kitchen bins requiring published home- and commercial-compost information. |
| Simply Bio 12–13 Gallon Heavy Duty Drawstring Liners | 12–13 gal; 29.4 × 23.7 in; 1 mil; 30-count drawstring format | BPI, OK COMPOST and Seedling claims; ASTM D6400 and EN 13432 listed | Tall kitchen bins where a drawstring is preferred. Treat performance descriptions as manufacturer claims. |
| HoldOn 13 Gallon Compostable Tall Kitchen Bags | 13 gal; 24 × 27 in; 0.98 mil; 40 bags per box; drawstring | BPI Certified Industrially Compostable | Standard tall kitchen bins entering an accepted industrial composting system. Do not represent this SKU as home compostable. |
| Natur-Bag 13 Gallon Compostable Bags | Retail pack: 23.5 × 29 in and 0.8 mil; industrial 13-gallon SKU also published | BPI and TÜV Austria information published; ASTM D6400 and EN 13432 listed | Retail, commercial and organics-diversion programs. Verify the exact retail or industrial SKU before comparing specifications. |
The difference between home and industrial compostability matters. A 13-gallon bag designed for industrial composting should not be represented as backyard compostable unless the exact finished product also carries appropriate home-compost certification.
B2B buyers developing a retail or commercial product can review ORIZON’s 13-gallon compostable trash bag manufacturing page for custom dimensions, thickness, closure, printing and packaging options.
How to Compare Published Brands Without Guessing About Performance
Product pages are useful when they tell you exactly which bag is being described. UNNI publishes a 2.6-gallon food-scrap format; Green Earth publishes dimensions for its 13-gallon bag. Those details make the products easier to compare for bin fit. They do not, by themselves, establish which bag will survive the heaviest wet load.
BioBag and EcoSafe provide examples of information relevant to commercial buyers. The BioBag 13-gallon page identifies its item and construction. The EcoSafe 33 × 39-inch page lists a SKU, thickness and case format. You still need to verify the latest documentation and test the product against your own program.
Is a BioBag suitable for home composting? Do not decide from the brand name. Check the exact BioBag item and its current home-compost documentation if backyard composting is your requirement.
Is an EcoSafe bag suitable for a commercial facility? Check the exact item’s documentation, then confirm acceptance with the facility that will actually receive it. The two checks answer different questions.
For a private-label or municipal project, you may find that none of the retail examples has your required size, roll count or printed instructions. At that point, move from brand comparison to a defined manufacturing specification.

Compare Bulk Best Compostabale Bags Quotations on the Same Specification
A low price per bag is not useful if the quotations describe different bags. Give each supplier the same project brief and compare the answers against the same fields.
| Field to align | What you should provide or confirm |
|---|---|
| Application | Food scraps, commercial organics, office waste or another defined use |
| Bin and bag size | Bin opening and height; required bag width, length and overhang |
| Performance conditions | Expected contents, approximate load, moisture, holding time and handling method |
| Construction | Flat or star seal; flat top, handles or drawstring |
| Film | Proposed thickness and finished-bag weight |
| Packing | Bags per roll, rolls per carton, carton markings and pallet requirements |
| Market and claims | Destination market, receiving program and required finished-product documentation |
| Commercial terms | Quantity for each SKU, sampling, production lead time and agreed shipping term |
If the dimensions, film weight, packing or shipping term change, the quoted unit price may change with them. For a multi-size range, specify the planned quantity of each SKU instead of giving one combined volume.
You can use ORIZON’s MOQ and lead-time guide when planning a custom order. Its standard custom-production starting point is approximately 500 kg per specification or design; the number of bags or rolls depends on the weight and configuration of the finished product. Trial or sample arrangements may differ from the mass-production MOQ.
What to Send for a Custom Compostable Trash Bag Review
You do not need a finished technical drawing to start. An existing bag, bin measurements or a brief description of the collection program can provide a useful first reference.
Send what you know:
- your business type and destination market;
- the waste the bag will collect and where it will be processed;
- bag dimensions, bin dimensions or a reference sample;
- expected load and how the bag will be lifted or moved;
- preferred closure, colour, printing and packing;
- estimated order volume for each size or design;
- any certification or labeling requirement specified by your customer or receiving program.
ORIZON can then review the proposed bag specification, manufacturing options and the certification information relevant to that finished product. Founded in 2009, ORIZON reports an approximately 20,000 m² manufacturing site, 16 automatic production lines and approximately 500 metric tons of monthly manufacturing capacity. Capacity is a production-planning figure; it does not establish certification for any particular custom bag. Review the company evidence.

FAQ
What are compostable bags made of?
Compostable trash bags can use different formulations, including starch-based components and polymers such as PLA and PBAT. “Plant-based” does not, by itself, establish that a finished bag is compostable. When you source a bag, check the finished product’s certification scope and intended composting conditions rather than relying on the name of one ingredient. European Bioplastics explains the material categories.
Are compostable bags really compostable?
A bag can be compostable under the conditions covered by its verified finished-product certification. You still need to distinguish home from commercial composting and confirm that the receiving program accepts the bag. You should not interpret a compostability claim as a promise that the bag will break down in landfill. EPA guidance
What are the most durable compostable kitchen trash bags?
You cannot identify a universal winner from thickness or customer reviews alone. Compare finished bags under the same wet-load, puncture, holding-time and lifting conditions. If you are purchasing for a brand or food-waste program, request samples and record how each bag performs in your actual bin and collection process.
Are biodegradable trash bags good?
The word “biodegradable” alone does not tell you where or how quickly a bag will break down. If your purpose is compostable food-waste collection, look for suitable finished-product compostability evidence and confirm acceptance with the receiving program. Avoid assuming that a biodegradable bag will break down after ordinary trash disposal. FTC guidance on environmental claims
What are the best compostable trash bags available for home use?
First decide whether you mean use in a household bin or composting in a backyard pile. For a small food-scrap caddy, UNNI’s 2.6-gallon bag is one published option to compare. For a larger kitchen bin, Green Earth’s 13-gallon bag publishes home-compost information. Neither is an independently tested durability winner in this guide. Verify the exact product, bin fit and current certification; if you use curbside collection, check its acceptance rules.
How do you choose a 3-gallon compostable bag for wet food scraps?
Measure your caddy opening and height, then consider how wet the contents become and how long they stay in the bag. Test whether the full bag can be removed using your normal method. A “3-gallon” label alone does not tell you enough about fit or wet-waste handling.
What should you include in a bulk inquiry?
Provide your destination market, application, bag or bin dimensions, estimated volume for each SKU, preferred closure and packing format. Include your customer’s certification requirements and any instructions from the receiving composting program. Approximate measurements are enough for an initial specification review.
