Summary:The present research work focused on fabricating Biodegradable Plate (BD plate) composed of rice husk ash, bagasse and corn starch which is harmless to the environment. Mechanical properties such as compressive strength, moisture absorption, solubility and infiltration time were examined in fabricated BD plate. Box–Behnken Design (BBD) and ANOVA analysis are employed to optimize the operating parameters includes raw material mix ratio, temperature on the die, pressure during the mixing process and time. Input factors such as temperature varies (80–100 ºC), pressure (1–3 bar), time (4–6 min) and Mix ratio (M1, M2 and M3) are coded into the BBD design. Lack of fit test, p and F value of the independent variables are calculated to confirm the significance of the regression model. Maximum compressive strength of 31 kgf is obtained at the optimal process parameters like temperature of 90 ºC, pressure of 2 bar, holding time of 6 min and Mix ratio of 2. The developed biodegradable plate serves as the alternative solution for plastic plates such that the developed plate withstands for 30 days free from fungus.
