As everyone's environmental awareness continues to improve, pet owners are increasingly inclined to choose environmentally friendly and practical compostable dog feces bags when dealing with dog excrement. This type of product can not only effectively avoid environmental pollution, but also ensure a worry-free user experience.
As a manufacturer of compostable bags in orizon, today I will help you sort out all aspects of compostable feces bags in detail, so that you can buy with confidence and use happily.
Why Choose Compostable Dog Waste Bags?
Traditional plastic dog waste bags are cheap, but they pollute the environment and take hundreds of years to decompose. The mountains of plastic waste have become a major problem for the global environment. Compostable dog waste bags (plant-based dog waste bags) use plant-based materials such as corn starch and biopolymers, which can decompose quickly under the right conditions, truly achieving "use and no harm".
These bags usually undergo strict environmental certification (such as ASTM D6400, BPI certification) to ensure degradation performance, and will not only decompose on the surface like some "degradable plastics". Choosing compostable bags not only reflects the owner's sense of responsibility for the environment, but also avoids the embarrassing broken bags and smell leakage during cleaning.
What Are the Compostable Certifications?
The most important thing to choose a truly environmentally friendly compostable dog poop bag is to see whether it has obtained authoritative certification. Mainstream certifications include:
ASTM D6400: Certified by the American Society for Testing and Materials, which ensures that the product can be completely degraded under industrial composting conditions and ultimately produces non-toxic residues.
BPI certification (Biodegradable Products Institute): Certified by the American Biodegradable Products Institute, independent third-party testing is more authoritative.
EN13432: EU standard, which also recognizes that the product can be decomposed into water, carbon dioxide and biomass within a specified time.
How to identify: Check whether the packaging or detail page is marked with the above labels and numbers. Certified brands usually display these qualifications in a high-profile manner. Be cautious about products that are not strictly certified, such as "degradable plastics" and "partial decomposition".
How Easy Are Plant-Based Dog Poop Bags to Use?
Size selection: Generally, there are three sizes: small, medium, and large (such as 7"x8", 9"x13"). Large dog families are recommended to choose large sizes.
Roll packaging: Most compostable poop bags are in rolls (15-20 per roll), which is convenient for daily carrying and use.
Packing box and hook: Many brands will give away packing boxes and hooks, which are convenient for hanging on the leash or waistband when going out, especially for owners who love to travel or walk their dogs for a long time.
Easy tear line design: Good humanized design, so that the bag can be operated with one hand without embarrassment.

Compostable Dog Poop Bag Types and Materials Comparison
Type | Main Material | Compostable | Price Range | Suitable Users | Pros and Cons Summary |
---|---|---|---|---|---|
Plant-Based Biopolymer Bags | Cornstarch, PLA, etc. | Yes | Medium-High | Eco-conscious users | Quickly decomposes in industrial composting, more expensive |
Degradable Plastic Bags | Mixed materials with degradants | Partially | Medium | Budget-conscious eco users | Longer degradation time, may leave residues |
Traditional Plastic Bags | Polyethylene (PE) | No | Low | Cost-conscious practical users | Not eco-friendly, difficult to decompose |
Plant-based materials such as PLA (polylactic acid) and corn starch products are the key to achieving true compostability.
Environmentally Friendly Dog Poop Bags Price and Cost-Effectiveness
Packaging specifications: Commonly 60, 120, 270, 540, etc. Large packages have lower unit prices and are suitable for multi-dog families.
Mainstream brands: Earth Rated, Greener Walker, Doggy Do Good, UNNI, etc., with reasonable average prices and reliable quality.
Price range: Certified compostable poop bags generally range from 0.25 to 0.5 yuan each, and in the long run, the cost-effectiveness is higher than that of cheap plastic bags (the "invisible value" of protecting the environment is greater).
How to Choose a Compostable Dog Poop Bag
Environmental certification
Bags marked with ASTM D6400 and BPI certification on the market are trustworthy choices. These certifications ensure that the bags can be completely decomposed into harmless substances in an industrial composting environment (high temperature and high humidity). Don't be deceived into buying fake environmentally friendly products that "add degradants but are difficult to degrade".
Durable and leak-proof design
Look at the thickness of the bag. Generally, the thickness of high-quality compostable bags is 0.8mm or above to ensure that they are not easy to break. In actual use, leak-proof design (such as heat-sealed seams) and pulling resistance are the key to avoiding embarrassment.
Size and easy unrolling
You can choose the corresponding size according to the size of your dog: 7"x8" bags can be used for small dogs, and 9"x13" size is suitable for large dogs. The roll design needs to be easy to tear and easy to carry. The packaging box with clip hooks is a thoughtful little helper for urban owners to walk their dogs.
Additional functions
Some compostable bags will be available in unscented and slightly scented versions for selection. Unscented products are more environmentally friendly and healthier, while scented products can temporarily cover up odors. In addition, whether the product comes with environmentally friendly packaging or paper packaging also reflects the brand's intentions.

FAQ
How long does it take for a compostable dog poop bag to decompose?
Generally speaking, under standard industrial composting plant conditions, it can be completely decomposed in about 90 days. The cycle will be longer in a home composting environment, but it is still much better than traditional plastic.
How to confirm that the bag you bought is truly compostable?
Check the packaging for ASTM D6400 or BPI certification marks, and read the ingredient list carefully to confirm whether it is plant-based material rather than ordinary plastic with added degradants.
What is the difference between compostable bags and degradable bags?
Compostable bags must meet the standards of being completely degradable and safely converted into compost; degradable bags may simply degrade and leave microplastics, and the harm to the environment still exists.
Are there reusable dog poop bags on the market?
Most of them are disposable items, and repeated use is risky and unhygienic.
