Verification Programme




The ABA launched Australian Standard 4736-2006, compostable and biodegradable plastics – “Biodegradable plastics suitable for composting and other microbial treatment” which is known as the ‘seedling logo’ certification system throughout Australia and New Zealand. The seedling logo clearly identifies and differentiates packaging materials as biodegradable and compostable. To be certified compostable and carry the seedling logo, suitable biopolymer materials must undergo a stringent test regime outlined by AS4736 and carried out by recognised independent accredited laboratories to the AS4736 standard.

Once successful testing is complete, application for formal certification can be made to the ABA directly via your supplier of biodegradable products. In turn the ABA has enlisted an independent third party testing laboratory to evaluate applications. If successful then an invitation is sent by ABA to license the seedling by payment of nominal fee and signing a license agreement. Successful applicants will then be licensed to use the logo along with their unique certification number.

The seedling logo is a symbol that the product’s claims of biodegradability and compostability as per AS4736 has been verified.

How to use the logo

Use of the seedling logo is available for use by both packaging material producers and their customers. The seedling logo can be printed on the finished product (eg. films, injection mouldings and bags) to market the product’s compliance to AS4736. Use of the seedling logo will ultimately help the end consumer, customers and/or municipal authorities to recognise compostable packaging and dispose of it accordingly. Importantly, the seedling logo will communicate the authenticity and independent verification of claims of compliance to AS4736‐2006.
