Mango seeds from agro-industry represents an environmental problem due to the amounts of by-products produced. Conversely, poly (lactic acid) (PLA) is a potential green alternative to conventional plastics. The goal of this study aimed to develop a biocomposite based on PLA and mango's by?product for rigid packaging. Six biocomposites were obtained by extrusion/injection processing using formulations with PLA as a matrix and up to 20% by weight of mango seed's by-products (integument or/and kernel). The materials were characterized by chemical analysis; helium pycnometry; particle size distribution; scanning electron microscopy/energy dispersive X-Ray (SEM/EDX), X-Ray diffraction (XRD); Fourier transform infrared spectroscopy (FTIR); thermal gravimetric analysis/differential thermogravimetry (TGA/DTG); differential scanning calorimetry (DSC), and mechanical analysis. Fourier Transform Infrared Spectroscopy (FTIR) bands and DSC transitions related to starch were higher in the kernel, while more cellulose bands were found in the integument. Kernel presented thermal degradation in the biocomposites, specifically the sample PLA+20 wt% kernel. For the other compositions, it was possible to observe that they could keep their morphology. Significant improvements in both mechanical and barrier properties were found in the formulation with 20 wt% integument (an increase of up to 38% in elastic modulus). Therefore, this study suggests that biocomposites developed from PLA / Integument / Kernel have potential as a new biomaterial for rigid food packaging systems.
