As plastic pollution becomes a growing global concern, governments around the world are introducing regulations aimed at reducing plastic waste and encouraging the use of sustainable materials.
One important area of policy development is compostable packaging regulations. These regulations define the requirements that packaging materials must meet in order to be labeled as compostable.
Understanding these regulations is essential for manufacturers, distributors, and brands that want to market compostable packaging products internationally.
This guide explains the major compostable packaging regulations and certification standards used around the world.
Why Compostable Packaging Regulations Exist
Without clear regulations, many packaging products could make misleading environmental claims.
Terms such as “biodegradable” or “eco-friendly” can be confusing and may not guarantee that the material breaks down safely.
Compostable packaging regulations help ensure that products:
• break down under controlled composting conditions
• do not release harmful substances
• do not contaminate composting systems
• meet recognized environmental safety standards
These rules help protect both consumers and composting infrastructure.
Major Compostable Packaging Standards
Several internationally recognized standards define the requirements for compostable plastics.
These standards typically evaluate biodegradation, disintegration, and environmental safety.
ASTM D6400 (United States)
ASTM D6400 is one of the most widely used compostable plastic standards in the United States.
The standard specifies requirements for plastic materials that can biodegrade in industrial composting facilities.
Materials must meet strict testing criteria related to:
• biodegradation rate
• disintegration during composting
• heavy metal limits
• plant toxicity

EN 13432 (European Union)
EN 13432 is the European standard for compostable packaging materials.
It defines the technical requirements for packaging to be considered industrially compostable within European waste management systems.
EN 13432 testing includes:
• biodegradation tests
• disintegration tests
• heavy metal limits
• ecotoxicity evaluation
This standard is widely used across Europe.
BPI Certification
The Biodegradable Products Institute (BPI) certification program is widely used in North America.
BPI certification verifies that products meet ASTM D6400 or ASTM D6868 compostability requirements.
Products that pass certification can display the BPI compostable logo, indicating that they meet industry compostability standards.
AS4736 and AS5810 (Australia)
Australia uses two compostable standards depending on composting conditions.
• AS4736 – industrial composting
• AS5810 – home composting
These standards help ensure compatibility with Australia's organic waste collection programs.

Labeling Requirements for Compostable Packaging
Many regions require strict labeling rules for compostable products.
Labels must clearly indicate:
• certification logos
• composting conditions
• disposal instructions
Incorrect or misleading labeling can result in regulatory penalties or product recalls.
Proper labeling helps consumers dispose of packaging correctly.
Regional Regulatory Trends
Compostable packaging regulations vary across different regions.
Europe
Europe has some of the most advanced packaging regulations in the world, including strict rules on plastic reduction and compostable packaging certification.
United States
The United States regulates compostable claims through standards such as ASTM D6400 and certification programs like BPI.
Some states also enforce specific labeling requirements.
Australia
Australia has adopted compostable certification standards such as AS4736 and AS5810 to ensure compatibility with organic waste collection programs.
Asia-Pacific
Many countries in Asia-Pacific are introducing new regulations to reduce plastic pollution and encourage biodegradable packaging solutions.
Challenges in Compostable Packaging Regulation
Although regulations are expanding worldwide, several challenges remain.
These include:
• inconsistent standards across regions
• limited composting infrastructure in some countries
• confusion between biodegradable and compostable products
Improving international standardization and waste management systems will be important for future industry development.
Future of Compostable Packaging Regulations
The regulatory landscape for compostable packaging is expected to evolve rapidly.
Future developments may include:
• stricter plastic reduction policies
• expanded composting infrastructure
• stronger labeling requirements
• international standard harmonization
As governments continue to address plastic pollution, compostable packaging regulations will likely become more comprehensive.
Conclusion
Compostable packaging regulations play a critical role in ensuring that environmentally friendly packaging materials meet strict safety and performance standards.
By understanding global compostable standards such as ASTM D6400, EN 13432, BPI certification, and AS4736, businesses can ensure compliance and successfully enter international markets.
As sustainability becomes a priority worldwide, these regulations will continue to shape the future of packaging innovation.
