What are the effects of using rice hull ash as a filler in WPC on planter mechanical properties?

Using rice hull ash (RHA) as a filler in Wood-Plastic Composites (WPC) has shown significant potential in enhancing the mechanical properties of planters. RHA, a byproduct of rice processing, is an eco-friendly and cost-effective material that improves the strength, durability, and thermal stability of WPC. Studies indicate that incorporating RHA into WPC matrices increases tensile and flexural strength while reducing material weight. Additionally, RHA's porous structure enhances water resistance, making it ideal for agricultural applications like planters. This sustainable approach not only reduces waste but also lowers production costs, offering a viable alternative to traditional fillers. Further research is needed to optimize RHA ratios for maximum performance in WPC-based planters.
