Abstract
The present research work focused on developing Biodegradable tableware composed of rice straw and plasticizers like sorbitol, polyvinyl alcohol (PVA). In the manufacture of the concentration of sorbitol used was 20%, 30%, 35%, and 40% and PVA used was 2%, 5%, and 10% by weight dry ingredients. Mechanical properties such as tensile strength, compressive strength, water absorption, were studied in fabricated BD plate. Maximum compressive strength of 55.79 kgf and tensile strength of 40.79 mpa is obtained at the optimal concentration of sorbitol and PVA is 30% and 5% respectively. The developed biodegradable tableware serves as the alternative solution for plastic tableware such that the developed plate withstands for one month free from fungus
