This research investigates a novel solution to sustainable product design through the use of rice bran, a large-scale agricultural by-product, as the major raw material for the production of biodegradable bowls. With escalating concern for environmental issues caused by plastic waste and the pressing need to create environmentally friendly replacements, this research examines the potential for converting rice bran, typically waste or utilized at minimal levels as animal feed, into a viable biodegradable product. The project highlights the viability and advantages of this solution for small farmers, especially in rice-growingareas, providing them with an alternative source of income and waste reduction. The study includes the development of rice bran composite tableware through the combination of rice bran with plant-based binders and additives, followed by low- cost, small-scale moulding techniques. The resulting bowls underwent extensive testing for determination of mechanical strength, water resistance, thermal stability, and biodegradability. Through the process of turning waste into wealth, this method not only helps in environmental sustainability but also supports circular economy tenets and rural development objectives. We assessed the effects of the RH to starch ratio (w/w %), pressing temperature (°C), and duration (minutes) on the hardness, colour variation, and density of the bowls, with the goal of optimizing the manufacturing process. A cost-effective manual die machine has been designed to process agricultural residues, enabling rural smallholders and women entrepreneurs to produce valuable products, thereby fostering circular economies and sustainable income. This research presents an innovative approach to addressing plastic waste while simultaneously enhancing the livelihoods of individuals in rural communities through the introduction of biodegradable rice bran bowls.
