[GreenYes] Re: plastic? or wax? coated milk cartons

["Johnston, Glenn" <Glenn_Johnston@no.address>]

Dear All,
 
Remember that just because a material disintegrates under appropriate
conditions such as ISO 16929 and is not visible, it does not mean that
the material is biodegradable.  The only true way to determine
biodegradation is to run (ASTM D5338 or ISO 14855) Aerobic Degradation
of Plastic Materials under composting conditions which measures the CO2
evolution and shows thu carbon balance that the material is actual
biodegrade via in situ composting organisms and does not leave small
particles behind.

Sorry folks, it was a while ago that AF&PA did the study on
compostability of these. You may want to check in directly with them as
my source thought they might have more up-to-date information.
