Abstract Scope |
The purpose of this study was to develop biodegradable PBAT/PLA packaging that promotes the circular economy by incorporating plant wastes from the agro-industry, contributing to environmental conservation, maximizing the use of resources, and reducing the dependence on non-renewable resources. In this study, composites based on PBAT/PLA, lignin (LIG), and rice husk ash (RHA) were prepared. First, using electron beam irradiation at 30, 60 and 90 kGy, the LIG was modified. Then, the LIG, irradiated LIG, and RHA were incorporated into a PBAT/PLA blend using a twin-screw extruder. Filaments produced were 3D printed by FDM. Non-irradiated and irradiated LIG were characterized by FTIR and XRD analysis. The composite samples were characterized by tensile tests, SEM, DSC and XRD analysis. According to results the incorporation of 5wt% of irradiated LIG and 5wt% of RHA into PBAT/PLA blend and 3D printing led to obtaining of composites with suitable properties for several industrial applications. |
