How We Tested and Evaluated These Compostable Trash Bags
We compared each compostable trash bag based on certification transparency, material type, available sizes, leak resistance, tear strength, wet food waste handling, home vs industrial composting compatibility, bag thickness, sealing performance, storage stability and real-world buyer feedback.
Because compostable bags can lose strength when exposed to moisture, heat or long storage times, we also considered shelf life and practical kitchen use.

How to Choose Compostable Trash Bags
When selecting compostable trash bags, consider these key factors:
1. Certification
Look for recognized standards such as BPI, EN 13432, TÜV OK Compost (Home / Industrial), or AS 4736. Certification ensures the bag will break down properly without leaving harmful residue.
2. Composting Environment
Not all compostable bags work in the same conditions. Industrial compostable bags require high temperatures, while home compostable bags are designed for backyard systems.
3. Thickness and Strength
Thicker bags (20–30 microns) are better for wet or heavy waste, while thinner bags are suitable for light kitchen scraps.
4. Size Compatibility
Always match the bag size with your bin. A poor fit can lead to tearing and leakage.
Common formats include:
- 1–3 gallon food scrap liners
- 13-gallon kitchen trash bags
- 30–50L heavy-duty bins
- 120L–240L wheelie bins
Always check both volume and bag dimensions.
Compostable Trash Bags, Garbage Bags, Rubbish Bags and Refuse Bags
The terms compostable trash bags, compostable garbage bags, compostable rubbish bags and compostable refuse bags are often used differently by region, but they usually refer to the same product category: certified compostable liners used for food waste, organic waste or bin lining.
In the US, “garbage bags” and “trash bags” are common. In the UK and Australia, buyers may search for “rubbish bags” or “refuse bags.”
Compostable vs Biodegradable Trash Bags
Although the terms are often used interchangeably, compostable and biodegradable trash bags are not the same.
Compostable trash bags must meet strict standards such as:
- BPI / ASTM D6400
- EN 13432
- OK Compost HOME
Biodegradable bags may break down over time, but many do not meet strict compostability requirements or may leave behind microplastics.
For food waste collection and composting systems, certified compostable trash bags are generally the better option.
Home Composting vs Industrial Composting Bags
Not all compostable trash bags are suitable for home composting.
Many compostable products are designed for industrial composting facilities, where temperature and humidity are tightly controlled.
Home compostable bags must meet stricter conditions because backyard compost systems operate at lower temperatures.
Home Compost Certifications
- OK Compost HOME
- AS 5810
Industrial Compost Certifications
- AS 4736
- BPI / ASTM D6400
- EN 13432

Alternatives to Plastic Trash Bags
If you are looking for alternatives to plastic trash bags, there are several options depending on your waste type and disposal system.
1. Certified Compostable Trash Bags
The most practical alternative when composting systems are available.
2. Paper Bags or Liners
Suitable for dry waste but not ideal for wet food waste.
3. Reusable Bins Without Liners
The most eco-friendly option, but requires frequent cleaning.
For most users, certified compostable trash bags remain the most practical balance between convenience, hygiene, and environmental performance.
What Are the Best Compostable Trash Bags?
The best compostable trash bags are those that:
- have verified compostability certifications
- match your composting system
- provide enough strength for your waste type
- fit your bin size correctly
For most households, certified 13-gallon compostable kitchen trash bags are the best option.
For home composting, choose OK Compost HOME certified products.
For heavy-duty use, thicker compostable trash bags with reinforced seals perform better.
Are Compostable Trash Bags Really Better for the Environment?
Compostable trash bags can reduce plastic pollution when used correctly within composting systems.
Unlike traditional plastic bags, certified compostable bags are designed to break down into water, CO₂, and biomass under controlled composting conditions.
However, compostable bags only provide environmental benefits when disposed of properly through industrial or home composting systems.
If sent to landfill, compostable bags may not fully decompose because landfills lack oxygen and microbial activity.
For households with food waste collection or composting access, certified compostable trash bags are generally a more sustainable alternative to conventional plastic garbage bags.

If you are sourcing compostable trash bags in bulk for retail brands, distributors, municipal food waste programs or private-label packaging, ORIZON supplies certified compostable trash bags with OEM size, thickness, roll format, carton labeling and certification support.
