Let us be clear…that oxo-biodegradable plastic is not normally marketed for composting, and it is not designed for anaerobic digestion nor for degradation deep in landfill…
This is something of a retreat on the part of leaders of the ‘oxo’ industry. Unfortunately, while Dr. Scott claims that ‘oxo-degradables’ are not marketed as compostable or biodegradable in landfills, this direction has not filtered down to the wide array of additive suppliers, who routinely make extravagant green marketing claims for products based on oxo-degradable additives. Check out this sample: a simple Google search of the combination “oxo-biodegradable + landfilling“.
Now that the oxo-biodegradable industry leaders have begun to pinpoint where they believe that their additives have value, it is up to them to make the data available to address the following questions:
1. How long will it take (and under what conditions) for products using these additives to fragment, which is a precursor to the possibility of any biodegradation?
