 Such plastic is not designed to be compostable in open industrial composting facilities, according to ASTM D6400 or EN13432; but it can be satisfactorily composted in an in-vessel process.ASTM D6400 and EN13432, the standards for industrial composting, require oxo-biodegradable material to convert to CO2 gas within 180 days by industrial composting, which is faster than degradation in the open environment.A leaf is generally considered to be biodegradable, but it will not pass the ASTM composting standards, due to the 180-day limit.
