“Oxo-biodegradable plastics are designed to biodegrade in ANY environment. It can’t be guaranteed where a customer will dispose of waste, therefore we have a technology that is an insurance policy on covering any environment it goes to. That includes, municipal waste, recycling centers, or even litter (accidental or otherwise).
“The important thing to note is that ASTM D6400 and D6868 is an industrial composting standard. That is not a home composting standard because there is no such thing as a home composting standard. Industrial composters are massive composting facilities that exert lots of energy and water to keep the material in ideal conditions for slow incineration, which is what is happening to the material. It should also be noted that D6400 is under critical review at ASTM because it does not meet the needs of industrial composters nation wide, who have begun to turn away ‘industrial compostable’ products. They take up to 180 days to meet the requirements of the standard, which is 90 days longer than most composters want it to last.
“On top of that, if a product approved under BPI guide lines, or ASTM D6400 guide lines, and ISN’T disposed of in an industrial composter, then it remains as waste and nothing will change that. Therefore, it’s an effective technology in only very specific conditions.
“However, an oxo-biodegradable plastic will both degrade and BIODEGRADE in a home composter, unlike other technologies. Because the technology doesn’t require water and high heat to perform, it means there is lots of flexibility.
“Unicorn Bags will have a hard time getting on the BPI list because the Biodegradable Plastics Institute is solely run by PLA, Starch, and composting companies. They do not let technologies like oxo-biodegradables into their ‘club’ since they don’t use one of their technologies. None of our products will pass composability testing because those tests were designed ONLY for hydro biodegradable resins (PLA, starch, etc). It’s essentially saying you want to judge a motorcycle on safety standards designed for a car. ASTM D6954 is the standard guideline for testing Oxo-biodegradable materials.”This document from the Oxo-Biodegradable Plastics Foundation explains more about this material. -Lou-
