Development of a Solar-Powered Smart Dustbin for Odor-Free, Pathogen-Controlled, and Health-Centrist Waste Management

This study presents an eco-friendly, dual-compartment smart dustbin designed to improve waste management by reducing odor, preventing contamination, and enhancing hygiene. The upper chamber (80%) collects solid waste and dries it using a solar-powered dryer to reduce volume, moisture, and bacterial growth. The lower chamber (20%) collects liquid waste, which is passed through a filtration system to remove harmful contaminants. A touchless infrared sensor enables automatic lid opening, ensuring hygienic and contact-free waste disposal. By separating wet and dry waste at the source, the system reduces odor, minimizes the release of gases such as methane and ammonia, and helps prevent the spread of bacteria like E. coli and Salmonella. With India recording nearly 1.7–2.1 million deaths annually due to pollution-related causes, this solar-powered smart dustbin offers a clean, sustainable, and health-focused solution for modern waste management. It supports better hygiene, protects public health, and promotes a cleaner environment.
