Test Data
Test with a mulch film (thickness 20㎛)
July 19, 2014 August 19, 2014 August 26, 2014
The above pictures show the decomposition process of the mulch film we have installed to test ourselves in 2014.
In 2013, before that, we provided our mulch film for a research at a Canadian university and got some test results as below in a report of 'Analysis of Aspergillus oryzae degradation of commercial agricultural mulch films composed of poly(butylene adipate-co-terephthalate) and poly(lactic acid)'.
"Though not a direct measure of biodegradation, the loss in mass of the mulch film supports the indication of biodegradation
via hydrolysis of the ester bonds.
Of the vessel incubation (44 days), Willeap film showed the greatest change in mass, being significantly greater than that of the
Abcde film (p =0.014) (Table 4).
During the cutinase assay incubation (15 days), Willeap film showed an even greater significant change in mass than either film
in vessel incubation (p = 0.006)."
