ComPlast Bags have undergone rigorous testing by approved authorities,
by Organic Waste Systems (DWS), based in Belgium.
We DO NOT however meet composting standards neither home nor Industrial because we are required to disintegrate 90% to pieces 2mm or smaller within 90 days. We disintegrate 85% within 90 days. We are working on a new formulation to meet this standard. Once met we will seek certification.
The following graph shows the tests that have been carried out.

|Standard Soil Biodegradation||60% at the end of test period.||ISO 17556||59.4%|

Please note that the ComPlast product disintegration levels approach, but do not yet meet the levels required for certification under EN13432 and AS4736 certification. However, after 12 weeks of aerobic composting 85% of a ComPlast test product will be in pieces 2mm in diameter or less (the requirement for certification is 90%).
What are bioplastics?
Recent testing done in New Zealand, by Scion, show that this product is a bioplastic basically made up of vegetable oils , cassava , starch with a marginal percentage of PCL. We continue to seek compostable certification as a Bioplastic.
