Abstract:Polylactic acid (PLA) is a bio-based plastic that is biodegradable under
appropriate conditions of temperature, humidity and oxygen, which are
achieved in the composting process. The objective of this work is to
formulate a mathematical model that predicts the biodegradation of
polylactic acid in composting processes. We performed a qualitative
analysis of the reduced composting mass system, which is non-linear and
non-autonomous. First, the reduced model was transformed into an
autonomous system, showing that… Show more
