Poly(lactic acid) (PLA) is a biodegradable thermoplastic polymer used in various applications, including food packaging, 3D printing, textiles, and biomedical devices. Nevertheless, it presents several limitations, such as high hydrophobicity, low gas barrier properties, UV sensitivity, brittleness. To overcome this issue, study, biochar (BC) produced through pyrolysis of bio-mass waste was incorporated (1 wt.%, 2wt.%, 3 wt.%—PLA 1, PLA 2, 3) to enhance thermal mechanical properties composites. The impact temperature on the kinetic parameters, physicochemical characteristics, structural banana orange peels for use added investigated. biomass were characterized by proximal analysis thermogravimetric (TGA); meanwhile, composites tensile straight, TGA, differential scanning calorimetry (DSC), electron microscopy (SEM), atomic force (AFM). results indicated that presence improved hygroscopic characteristics Tg from 62.98 °C 1 wt.% 80.29 wt.%. Additionally, found strength increased almost 30% compared with 1. Young’s modulus also 194.334 MPa PLA1 388.314 PLA3. However, elongation decreased 14.179 (PLA 1) 7.240 mm (PLA3), maximum degradation shifted lower temperatures ranging 366 PLA-1 345 PLA-3 samples, respectively. From surface analysis, observed these samples relatively smooth, but small microcluster BC aggregates visible, especially composite. In conclusion, incorporation into promising method enhancing material performance while maintaining environmental sustainability recycling waste.
