ComPlast Bags have undergone rigorous testing by approved authorities, demonstrating that they are 100% biodegradable, surpassing the aerobic biodegradation requirements for ASTM D6400, EN13432 and AS4736 certification. ComPlast products are non-toxic, a requirement for EN13432 and AS4736 certification. The following tests have been carried out by Organic Waste Systems (DWS), based in Belgium.

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%). Petroleum based plastic bags sometimes have a range of mineral and chemical accelerants added at the manufacturing stage to quicken their disintegration speed, which allow them to meet the composting standards.
Some petroleum based plastic bags have 50% plant-based material added at the manufacturing stage in order to qualify within the regulations as compostable.
ComPlast Bags are 99.5% organic material and take longer to decompose but, unlike petroleum bags, return to a natural state.
