Abstract

Polylactic acid PLA is increasingly utilized as an alternative to petroleumbased polymers in order to reduce their impact on the environment The monomer of PLA is mainly produced from corn which in addition to its food utilization can be also used for the production of bioethanol or biofuels In this work the depolymerization chemical recycling of PLA pellets in a batch reactor at temperatures near the melting temperature of solid PLA has been investigated to produce lactic acid New experimental data are presented and a kinetic model is provided for a first analysis With a residence time less than 120 min a yield of lactic acid greater than 95  has been obtained at temperatures of 160 and 180 °C for pressure equal to water vapour pressure and a water/PLA ratio by weight equal ~10
