The escalating generation of Municipal Solid Waste (MSW) necessitates efficient source-level segregation to maximize recycling and composting rates while mitigating environmental impact. Conventional manual sorting is labor-intensive and error-prone. This paper presents an automated Smart Waste Segregation System designed to precisely classify and separate waste into wet (organic) and dry (recyclable) categories at the point of disposal. The system utilizes a moisture sensor integrated with a microcontroller (e.g., Arduino or PIC) to accurately differentiate between waste types based on moisture content. A servo motor controls a physically route the waste into its respective compartment. Furthermore, an ultrasonic sensor is implemented to continuously monitor the fill-levels of the bins, and an IoT-based communication module transmits real-time alerts to waste management authorities, thereby optimizing collection logistics. This cost-effective, automated solution significantly enhances sorting accuracy, reduces contamination, and promotes a more efficient and sustainable approach to urban solid waste management.
