Abstract	Food waste forms a major portion of municipal solid waste and is a significant contributor toenvironmental pollution when disposed of improperly. Most households continue to discardbiodegradable waste in landfills, leading to greenhouse gas emissions and health hazards. This study focuses on the design and development of a low-cost, hand-operated food shredder compostersuitable for domestic use. A primary survey was conducted to assess household food wastegeneration, disposal practices, and user interest in manual composting systems. Based on the survey responses, a simple, durable, and cost-effective prototype was designed using mild steel as theprimary material. Material selection was optimized using the Multi-Criteria Decision Making(MCDM) method by evaluating factors such as cost, strength, ductility, weldability, corrosion resistance, recyclability, and availability. Mild steel was found to be the most suitable material forfabrication, offering a balance between strength, manufacturability, and affordability. The proposedcomposter efficiently shreds and processes household food waste into smaller biodegradable particles, facilitating rapid composting while minimizing energy use and environmental impact.
