How is oxo-biodegradation different from compostable?
Oxo-biodegradable plastics degrade as a result of physical and chemical oxidation impact, the molecule in chains are fractured into smaller and smaller pieces and after a certain point biodegradation takes over and all that will remain is H2O, CO2 and biomass. Compostable plastics degrade as a result of aerobic and anaerobic bacterial activity. Unlike conventional plastics and oxo-biodegradable plastics, bio-polymer plastics are made by starch (usually corn or sugar) – PLA materials. Definitions of the types on degradable plastics: Oxo-biodegradable plastic or Biodegradable plastic- a plastic designed to undergo a significant change in its chemical structure under specific environmental conditions resulting in a loss of properties and thereupon actions of micro-organisms completes the degradation/biodegradation (as described in ASTM D 6954-04). Compostable plastic – a degradable plastic in which the degradation results from the action of naturally occurring micro-organisms such as bact
