As brands move toward more sustainable packaging, the term “compostable bag” is appearing on more food packaging, retail bags, produce bags, mailers, and organic waste bags.
But not all compostable bags are designed to break down under the same conditions.
For packaging buyers, one of the most important distinctions is:
Home compostable bags vs. industrial compostable bags.
The short answer is simple:
Home compostable bags are designed to break down under relatively low-temperature, less-controlled home composting conditions, while industrial compostable bags require the controlled temperature, moisture, aeration, and microbial activity found in commercial composting facilities.
Understanding this difference can help brands choose the right materials, certifications, disposal claims, and packaging specifications for their target market.
A home compostable bag is designed to biodegrade and disintegrate under conditions similar to those found in a properly managed household compost pile or compost bin.
Unlike commercial composting facilities, home compost systems normally operate at relatively low and fluctuating temperatures. Conditions vary according to climate, moisture, aeration, compost volume, and how frequently the compost is turned.
Because these conditions are less controlled, packaging intended for home composting must be capable of breaking down without relying on the sustained high temperatures commonly used in industrial composting.
Common home compostability certifications and standards buyers may encounter include:
OK compost HOME
AS 5810 in Australia
NF T 51-800 in France
EN 17427 for certain home-compostable carrier bags
DIN CERTCO home compostability certification schemes
Certification requirements vary by market and product type, so buyers should always confirm which certification applies to the intended sales region.
An industrial compostable bag, sometimes called a commercially compostable bag, is designed to break down in controlled industrial or municipal composting facilities.
These facilities manage conditions such as:
temperature,
humidity,
oxygen,
microbial activity,
composting time,
and material turnover.
Industrial composting typically operates at substantially higher and more consistent temperatures than household composting.
For packaging sold in Europe, EN 13432 is one of the most widely recognized standards for industrially compostable packaging.
Depending on the market, buyers may also encounter standards and certifications such as:
EN 13432
ASTM D6400
AS 4736
EN 14995
OK compost INDUSTRIAL
Seedling certification
Meeting one industrial compostability standard does not automatically mean that a bag is suitable for home composting.
Factor | Home Compostable Bags | Industrial Compostable Bags |
|---|---|---|
Composting environment | Household compost pile or bin | Commercial or municipal composting facility |
Typical temperature | Lower and variable | Higher and controlled |
Composting conditions | Less predictable | Professionally controlled |
Degradation period | Generally longer | Generally faster under controlled conditions |
Certification examples | OK compost HOME, AS 5810, NF T 51-800 | EN 13432, ASTM D6400, AS 4736 |
Consumer convenience | Can be suitable for households with composting access | Requires access to an accepting composting facility |
Disposal claim | “Home compostable” only when appropriately verified | “Industrially compostable” or “commercially compostable” |
Infrastructure dependency | Lower | Higher |
The most important takeaway for buyers is that “compostable” alone is not specific enough.
A packaging specification should ideally state the composting environment and applicable certification.
Not necessarily.
Home compostability may sound like the more environmentally attractive option, but the right solution depends on how the packaging will actually be used and disposed of.
For example, home compostable bags can make sense when:
consumers commonly have access to home composting,
the packaging is likely to be contaminated with organic material,
local regulations support home compostable products,
and the bag has been independently certified for its intended claim.
Industrial compostable packaging may be more suitable when:
municipal food waste collection is widely available,
compostable packaging is accepted by local facilities,
the application requires specific mechanical or barrier performance,
or the brand is operating within an established commercial composting system.
The most sustainable packaging is not simply the material with the strongest environmental claim. It is the packaging that matches the product, market, collection system, and realistic end-of-life pathway.
One of the biggest purchasing mistakes is assuming that materials described as “biodegradable,” “bio-based,” or “eco-friendly” are automatically compostable.
They are not interchangeable terms.
A material may be produced partly or completely from renewable biological resources while still being non-compostable.
Biodegradation depends heavily on environmental conditions such as temperature, moisture, oxygen, microbial activity, and time.
A more meaningful packaging claim is:
Certified home compostable
or:
Certified industrially compostable
rather than simply:
Biodegradable bag.
When sourcing compostable packaging, buyers should therefore request certification documents for the finished product or relevant packaging construction, rather than relying only on general sustainability statements.
Certification requirements depend on where the packaging will be sold.
For industrially compostable packaging, buyers frequently look for compliance with:
EN 13432
This standard evaluates factors such as biodegradation, disintegration, compost quality, and limits on certain substances.
The Seedling and OK compost INDUSTRIAL marks are commonly associated with industrial compostability certification.
For home compostability, certification schemes such as OK compost HOME or relevant national and product-specific standards may be applicable.
ASTM D6400 is commonly referenced for plastics designed to be composted in municipal or industrial aerobic composting facilities.
Buyers should also evaluate labeling requirements and local or state regulations before marketing a product as compostable.
Two standards are particularly relevant:
AS 4736 — commercial/industrial compostability.
AS 5810 — home compostability.
This distinction is especially useful for buyers because it clearly separates products intended for commercial composting from products intended for home compost environments.
Buyers should not assume they can.
Industrial compostable materials are normally tested under conditions designed to simulate controlled commercial composting.
A household compost pile may never reach or maintain comparable temperatures.
As a result, an industrially compostable bag may remain visible for much longer in a home compost system or may not adequately break down under those conditions.
Unless the packaging also carries appropriate home compostability certification, it should not be marketed as home compostable.
From a material-degradation perspective, a product designed to compost under lower-temperature home composting conditions may also be capable of biodegrading under higher-temperature composting conditions.
However, actual acceptance depends on the composting facility.
Commercial compost operators may have their own rules regarding certified compostable plastics, packaging formats, food-service items, liners, labels, and contaminants.
Therefore, brands should not assume that every composting facility will accept every certified compostable bag.
Local infrastructure should always be checked.
Depending on product requirements and local regulations, compostable flexible packaging may be considered for applications such as:
Suitable structures may be developed for selected products including snacks, bakery products, produce, dry foods, and other applications where required shelf-life and barrier properties can be achieved.
Fresh produce and supermarket applications are among the most recognizable uses of compostable films.
Retail carrier bags can be designed using certified compostable materials, subject to local bag regulations.
Compostable liners can be particularly useful for collecting food waste where the bags are accepted together with organic waste.
Certain e-commerce businesses use compostable mailers as an alternative to conventional plastic shipping bags.
However, packaging buyers should remember that compostability is only one performance requirement.
A commercially viable package must also meet requirements for:
tensile strength,
puncture resistance,
seal strength,
moisture barrier,
oxygen barrier,
product shelf life,
printing,
storage,
and transportation.
Before placing an order, packaging buyers should ask more than:
“Is this bag compostable?”
A better supplier qualification checklist includes:
The supplier should provide a specific answer rather than using the general term “compostable.”
Ask whether the packaging is tested or certified according to standards such as EN 13432, ASTM D6400, AS 4736, AS 5810, or another relevant specification.
Material certification does not always automatically cover every finished packaging construction.
Printing inks, adhesives, zippers, valves, labels, coatings, and other components can affect the final package.
Compostability alone does not determine whether a packaging structure can protect coffee, snacks, pet food, frozen foods, powders, or other products.
Barrier requirements should be evaluated separately.
Certification and labeling requirements can vary between Europe, North America, Australia, and other regions.
Clear disposal information helps reduce consumer confusion.
Examples may include:
Home Compostable
or
Industrially Compostable — Check Local Collection
depending on the verified end-of-life pathway.
There is no universal answer.
Choose home compostable packaging when consumers realistically have access to suitable home composting conditions and the packaging is certified for that environment.
Choose industrial compostable packaging when an established commercial organic-waste collection and composting system exists in the target market.
For multinational brands, the decision may need to be made market by market.
A packaging structure that works well in Australia, for example, may face different certification, infrastructure, and labeling requirements in the United States or Europe.
That is why compostable packaging should be treated as an end-to-end packaging system, rather than simply as a material substitution.
Before approving your next compostable packaging project, confirm:
What product will the bag contain?
What shelf life is required?
What barrier performance is required?
Will consumers use home or municipal composting?
Is composting infrastructure available in the target market?
Which compostability certification is required?
Does certification apply to the finished bag?
Are inks, adhesives, closures, and accessories compliant?
What environmental claim will appear on the package?
Are local labeling regulations satisfied?
Answering these questions early can prevent expensive packaging redesigns, incorrect sustainability claims, and consumer confusion.
Home compostable bags are designed to biodegrade under lower-temperature household composting conditions. Industrial compostable bags are designed for controlled commercial composting facilities with higher and more consistent temperatures, moisture, and aeration.
No. EN 13432 is primarily associated with packaging intended for industrial composting conditions. A product claiming home compostability should have suitable home-compost certification or compliance for the applicable market.
ASTM D6400 primarily covers plastics intended for composting in municipal or industrial aerobic composting facilities. Buyers should not use ASTM D6400 alone as proof of home compostability.
Depending on the market, examples include OK compost HOME, AS 5810, NF T 51-800, or other applicable home-compost certification schemes and standards.
No. “Biodegradable” describes the ability of a material to biodegrade under certain environmental conditions, while certified compostability requires compliance with specific criteria and composting conditions.
Yes. Compostable packaging can be customized in dimensions, printing, closure options, film structures, and other features, but each component should be assessed to ensure that the required compostability claim remains valid.
They can be suitable for selected food applications, but compostability does not automatically guarantee sufficient oxygen, moisture, aroma, grease, or light barrier performance. Packaging should be engineered according to the food's shelf-life requirements.
The difference between home compostable and industrial compostable bags is not just terminology — it determines where and under what conditions the packaging is designed to break down.
For packaging buyers, the safest approach is to verify three things before sourcing:
Where will the packaging be composted?
Which certification supports the claim?
Does the finished package meet the required product performance?
Choosing the right compostable packaging means matching material performance, certification, local infrastructure, consumer behavior, and disposal conditions.
