Abstract
Background: The growing focus on environmental sustainability and safety has heightened the demand for eco-friendly household materials. This study explores the development of a bio-based board using rice husk (RH), assessing its properties and potential for diverse applications. Methods: The board was formulated using 30 g RH powder, 2 ml glycerol, 4 g agar, 3 g calcium propionate, and 100 ml water. The study involved visual and textural evaluation, physical property testing, and microbial growth assessment. Practical utility was examined through the fabrication of various objects including boxes and candle bases, and material adaptability was tested by varying RH concentrations and additives. Results: The RH boards, with equal proportions of RH and RH powder, exhibited light weight and good physical characteristics. Microbial growth was limited to 39% under conditions of 37 °C and 95% humidity. The boards were moldable, with a smooth, easily colorable surface post-sanding, demonstrating shape stability and flame retardancy under prolonged heat exposure. Furthermore, the material demonstrates good compatibility; varying RH ratios, colorants, and preservatives yield different appearance effects and characteristics. Conclusions: This study successfully developed a sustainable, safe, and versatile RH board, showcasing significant commercial potential and suitability as an innovative eco-friendly material.
