There have been many research involving to mitigate the environmental impact by changing the plant processing waste towards the circular economy concept. The basic approach would be 3R (Reduce, Reuse, and Recycle)
Therefore, this research was aimed to recycle approach by adding value to waste from processing of Sanpatong sticky rice seedling. Disposable container was made from starch foam mixed with waste from processing of Sanpatong sticky rice seedling by compression molding method. The content of waste of rice seedling was not more than 14 weight percent of starch foam. The compression condition is 170oC with the pressure of 13.8 MPa. The area, the thickness, and the density of disposable container are 144 cm2, 1-2 mm. and 0.20-0.46 g/cm3, respectively. The disposable container is light and the density does not depend on the content of waste of rice seedling. The flexural strength of disposable container is about 3.2-3.5 MPa which is lower than that of commercial one (4.18 ? 0.45 MPa). The water adsorption of disposable container 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.
