Abstract

To reduce plastic waste and integrate renewable sawdust into the circular economy, this research investigates the properties of sawdust-reinforced plastic (SRP), made from recycled high-density polyethylene (HDPE) and pine sawdust. The results show that adding sawdust to HDPE plastic reduces the density of the samples. A slight increase in compressive strength, up to 22.7 MPa, was also observed. Furthermore, the ultrasonic transmission speed decreased by 12.3%. This study suggests the potential for improving the processing of wafers and integrating them with nanomaterials to enhance their durability, as well as expanding the industrial applications of SRP. The results also provide a comprehensive experimental model that demonstrates the relationship between mixing ratios, structural composition, and function, thereby improving our understanding of the relationship between molecular structure and mechanical and acoustic properties.
