Study of pro-oxidant additive containing plastics i.e. plastics which are designed to degrade in the unmanaged natural environment (open-air, soil, aquatic) through oxidation and other processes which includes ?oxo-degradable plastics, oxo-biodegradable plastics and those containing biotransformation additives. The study indicates that there is no reliable data to substantiate the claim that OXO?s biodegrade in real conditions across a range of environments and climates.
