Reprocessed polylactide: Studies of thermo-oxidative decomposition

► The behavior of reprocessed PLA under combustion is assessed by TGA/FT-IR. ► The function TDB and the parameter ZDT are applied to assess thermal stability. ► The evolution of the kinetic parameters [Ea, lnA, f(α)−n] with α is assessed. ► The technologies for the control of gases can be transferred to treat reprocessed PLA. ► The combustion of reprocessed PLA can be efficient.
