Abstract
Recently, it has been of great interest involving to mitigate the environmental impact by changing the plant processing waste towards the circular economy concept. This research was aimed to add value to waste from processing of Sanpatong sticky rice seedling. Disposable plate was made from starch foam mixed with waste from processing of Sanpatong sticky rice seedling by compression molding. The content of rice seedling waste was not more than 14 weight percent of starch foam. The compression condition is 170oC with the pressure of 14 MPa. The area, the thickness, and the density of disposable container are 144cm2, 1-2 mm. and 0.20-0.46 g/cm3, respectively. The disposable plate is light and the density does not depend on the content of waste of rice seedling. The flexural strength of disposable plate is about 3.2-3.5 MPa which is lower than that of commercial one. The water adsorption of disposable plate decreased when adding not more than 10wt% of kaolin and latex rubber in starch foam. Coating with polylactic acid on disposable container can also reduce the water adsorption.
