<br/><br/> Increasing consumption of poultry has been associated with piling up enormous wastes in<br/>the amounts of chicken bones that are disposed of in landfills, causing environmental<br/>pollution, odor problems, attraction of vectors, and poor management of this waste. At the<br/>same time, there is an increasing demand for sustainable and locally produced bone-derived<br/>materials for agricultural and food-related applications. Processing bone in existing<br/>technologies is expensive, energy-intensive, and designed for industrial-scale operations,<br/>making them unsuited for small farms or households or microenterprises. The purpose of<br/>this capstone project is to design, fabricate, and evaluate a low-cost, portable pulverizer for<br/>chicken bones, which addresses the problem being discussed here. A hammer mill-based<br/><br/>pulverizing mechanism was developed utilizing a direct drive system with a 220 V single-<br/>phase AC motor, and safety features were embedded on the machine. To make it<br/><br/>economically feasible, materials used were very affordable and locally available. The meat<br/>bones used as a test sample were cleaned, heat-treated, and mechanically processed to test<br/>the performance of the machine. The efficiency of the prototype was evaluated by the<br/>Technological University of the Philippines (TUP) Evaluation System concerning<br/><br/>pulverization efficiency, particle size uniformity, functionality, safety, durability, and cost-<br/>effectiveness. The machine effectively converts processed chicken bones into fine powder<br/><br/>homogeneous in size and can be used in agriculture and possibly food-grade applications,<br/>whereas manual labor and operational risks are reduced.<br/>Keywords: Chicken Bone Waste, Bone Pulverizer, Hammer Mill, Agricultural Waste<br/>Recycling, Low-Cost Machine Design,
