Abstract

This study aimed to investigate the degradation behavior and surface morphology of polylactic acid (PLA) biocomposites reinforced with sugarcane bagasse fibers (SCBF). The biocomposites were fabricated using the vacuum bagging technique with fiber loadings of 0, 22, 24, and 26 wt%. Their performance was evaluated through a 21-day soil burial test, water solubility test, and surface morphology analysis using a digital optical microscope. The results revealed that the incorporation of sugarcane bagasse fibers enhanced the biodegradation rate of the PLA biocomposites under soil burial conditions. The highest weight loss (17.02%) was obtained for the biocomposite containing 26 wt% SCBF after 21 days of burial, which was attributed to microbial activity and the hygroscopic nature of the natural fibers. In contrast, the addition of SCBF reduced the water solubility of the biocomposites due to the formation of a denser fiber network within the PLA matrix, which restricted water penetration and improved structural integrity. Morphological observations confirmed surface degradation after soil burial, as evidenced by the formation of cracks, fissures, and voids on the biocomposite surface. Overall, the incorporation of sugarcane bagasse fibers effectively improved the biodegradability of PLA biocomposites while maintaining lower water solubility, highlighting their potential for environmentally friendly packaging applications.

Abstract

This study aims to examine the mechanical properties, surface morphology, and biodegradability of polyvinyl alcohol-potato starch biocomposites with lemon peel powder as a filler. The biocomposites were produced by solution casting with 1%, 2%, and 3% fillers of lemon peel powder. Mechanical properties were tested to determine tensile strength in accordance with ASTM D882. The addition of lemon peel powder increased tensile strength as the percentage content increased. The highest tensile strength was 4.82 MPa in polyvinyl alcohol-potato starch biocomposites containing 3% lemon peel powder. This indicates that lemon peel powder effectively improves bonding with the matrix and produces stronger interfacial bonds. However, the flexibility of the biocomposites decreased with increasing lemon peel powder content, as indicated by a decrease in elongation. Furthermore, the biodegradation of the biocomposites showed that the biocomposite with the highest lemon peel powder content (3%) exhibited the fastest degradation rate, reaching 65.22% after 15 days of testing. These results indicate that the presence of lemon peel powder improves the mechanical properties of the biocomposite without reducing its biodegradability. These findings indicate that biocomposites made from polyvinyl alcohol and potato starch with lemon peel powder are a promising sustainable plastic alternative, combining strength, flexibility, and degradability.
