Аннотация:The degradation of polylactide (PLA) films of different structures under conditions ofcontrolled composting has been studied. We have demonstrated that PLA underwent degradationwithin one month in a substrate that simulated standard industrial composting. Regardless of theinitial structure of the samples, the number-average molecular weight (Mn) decreased to 4 kDawhile the degree of crystallinity increased to about 70% after 21 days of composting. Addition of aninoculant to the standard substrate resulted in the accelerated degradation of the PLA samples forone week due to an abiotic hydrolysis. These findings have confirmed that industrial compostingcould solve the problem of plastic disposal at least for PLA.
