- Corn-starch: Corn starch itself can be used in combination with other biodegradable polymers to create compostable films. It’s a readily available and renewable resource.
- Cellulose: Derived from plant fibers (e.g., wood pulp, cotton), cellulose can be processed into films suitable for compostable bags.
Compostability Standards
To ensure a bag is truly compostable, look for certifications from reputable organizations. These certification verify that the bag needs specific standards for biodegradation and non-toxicity.
- ASTM D6400: Bags that meet ASTM D6400 standard for compostability in industrial composting facilities are referenced by BPI (Biodegradable Products Institute) in North American.
- OK compost INDUSTRIAL &OK compost HOME: TÜV AUSTRIA offers several certifications, including “OK compost INDUSTRIAL” (for industrial composting), “OK compost HOME” (for home composting), and “OK biodegradable SOIL” (for biodegradation in soil). These certifications are widely recognized in Europe.
- EN 13432: The European standard for commercial compostable.
- AS 5810: The standard is verified as home compostable by Australasian Bioplastics Association (ABA)
- AS 4736: The bag with “compostable” and “AS 4736” logo are certified by Australasian Bioplastics Association (ABA).
