step is the hydrolysis which reduces the molecular weight of the
PLA, and the second step is the assimilation by the microorganisms
[5]. Apart from this general understanding, biodegradability of
plastics in composting conditions is affected by several interconnected
physical and environmental factors that cannot be
simulated in simple laboratory tests. As matter of fact, the only way
to determine the compostability of a plastic is to carry out biodegradation
test methods [6,7].
