*Time requirement for biodegradation is dependent on a number of environmental factors such as temperature, moisture, Ph level and the quantity & quality of microorganisms – degradation results may vary.
Here is another test (Bio-Methane Potential test) conducted by independent lab- Eden Lab – New Mexico.  This anaerobic test was conducted over 105 days and confirms a 28.4% rate of biodegradation of PE treated with ENSO RESTORE™.  It is important to understand that RESTORE™ is only being used at 1% to 99% PE – scientifically confirming that the PE is certainly biodegrading, since the rate (28.4%) far exceeds the load rate of RESTORE™ of 1%.
 
As explained to George (Continental Poly) burying a bag in soil (aerobic enviornment) is not the optimal disposal environment because it doesn’t contain the same microbes as found in landfills.  As you know, your bags won’t be buried by the consumer in their back yard, but rather disposed of in a landfill (anaerobic environment), which is why the proper testing needs to be applied.  Labs such as Eden Lab, replicates the landfill environment in their lab to achieve the most accurate results.
 
The proper “landfill” tests are:
ASTM D5988 (Aerobic “Litter” Test)  https://www.astm.org/Standards/D5988.htm
 
This independent test (Sept. 18, 2015) confirms a rate of 68.4% biodegradation of the PE film in 410 days.
