What are the Pods made of and are they certified compostible to Australian standards?

Our Pods currently have EN13432 (European-Bioplastics Certification) which is the international standard for composability. However, we are in testing currently for the additional AS4736 certification (Australian Bioplastics Certification) which is the EN13432 certification with an additional worm toxicity test. We have been told the capsule will pass this test but there is a slight delay in getting the certification. We are hoping to have this soon though.
