Abstract - The improper disposal of medical waste continues to pose severe threats to both public health and environmental sustainability, particularly in densely operated healthcare facilities. Traditional waste collection systems often struggle with inefficiencies such as delayed pickups, overflowing bins, and lack of accountability, all of which can lead to hazardous outcomes. In response to these challenges, this project proposes an intelligent, IoT-based waste management system tailored specifically for hospitals and medical centres. By deploying sensors that continuously monitor bin fill levels, the system generates automated alerts when predefined thresholds are reached. Integrated GPS functionality allows real-time location tracking of bins, aiding in efficient waste collection logistics. A centralized platform manages status updates and role-based notifications, enabling hospital staff and waste handlers to stay coordinated and informed throughout the disposal cycle.
This technology-driven approach promotes a cleaner, safer, and more sustainable medical environment by automating routine tasks and improving operational responsiveness.
