Pirólisis de residuos de bioplásticos: Productos obtenidos del ácido poliláctico (PLA) Productos obtenidos del ácido poliláctico (PLA)

Abstract

Pyrolysis of bioplastics waste may offer an alternative waste treatment option, allowing the recovery of resources. Bioplastics have taken special interest in the industry. They could be an alternative to conventional petroleum based plastics. Polylactic acid (PLA) is a bioplastic that has gained big interest during the last two decades. Pyrolysis of bioplastics waste may be economically and environmentally attractive. In order to obtain optimal energy recovery with an appropriate composition of emitted products, pyrolysis treatment has to ensure the adequate conditions. In this work, the thermal degradation of PLA was studied by pyrolysis coupled with gas chromatography and mass spectrometry detection. The test conditions allowed to identify and quantify the major compounds produced during thermal degradation of PLA.
