eco Greenwares definition of Biodegradable and Compostable
We have done a lot of research on the definition of Biodegradable and Compostable products. You can find more info on our website at http://www.ecogreenwares.com/index.html. What is degradable Plastic? A degradable plastic which undergoes a significant change in its chemical structure under specific environmental conditions resulting in a loss of some properties. There is no requirement that the plastic has to degrade from the action of "naturally occurring microorganism" or any of the other criteria required for compostable plastics. What is Biodegradable Plastic? A Biodegradable plastic in which the degradation results from the action of naturally occurring microorganisms such as bacteria, fungi and algae (ASTM D 6400-99) What is Compostable Plastic? A plastic that undergoes degradation by biological processes during composting to yield CO2, water, in organic compounds, and biomass at a rate consistent with other compostable materials and leaves no visible, distinguishable or toxic residue (ASTM D 6400-99) What causes the process of biodegradation to begin? A biodegradable product will only biodegrade if it is in an environment which includes moisture, heat, and microorganisms. Without those three components, there will be no biodegradation.
