Abstract
Rapid urbanization and shifting consumption patterns have led to an unprecedented increase in municipal solid waste generation, posing significant environmental and public health challenges. Traditional manual waste sorting is inefficient, unhygienic, and increasingly hazardous for waste management workers. This project presents the design and fabrication of an automated, smart Waste Segregation System capable of detecting and sorting mixed waste into three distinct categories: metallic, wet/organic, and dry/plastic. The physical architecture of the system consists of a hopper-fed conveyor belt driven by a high-torque DC motor, mounted on a durable structural frame. The intelligence of the system relies on an array of sensors integrated with an Arduino Mega microcontroller. An inductive proximity sensor is utilized to identify metallic objects, while a calibrated moisture/capacitive sensor detects organic and wet matter. Items that do not trigger these sensors are classified by default as dry non-metallic waste (such as plastics or paper). Upon material identification, the microcontroller processes the signals in real time and activates a mechanical sorting mechanism—consisting of servo-controlled flaps and pneumatic actuators—to direct the waste item into its designated collection bin. Experimental testing of the fabricated prototype demonstrated a high sorting accuracy rate of approximately [Insert your percentage, e.g., 92%] with an average processing time of [Insert time, e.g., 2–4 seconds] per item. The system successfully minimizes human intervention, increases recycling efficiency, and offers a cost-effective, scalable solution for smart city waste management initiatives.

Abstract
Effective waste management remains a critical challenge in many urban and rural communities, particularly in developing countries where improper disposal contributes to environmental pollution and public health risks. This project focuses on the design and fabrication of a waste segregation system aimed at improving the sorting of municipal solid waste at the source. The system is engineered to automatically separate waste materials into distinct categories such as biodegradable, non-biodegradable, and recyclable components using a combination of sensors, mechanical components, and control mechanisms.
The design incorporates affordable and locally available materials to ensure cost-effectiveness and ease of replication. Key components include a conveyor mechanism, sensing units for material identification, and sorting bins for categorized waste collection. The fabrication process involved assembling the mechanical framework, integrating electronic control systems, and testing the functionality of the system under different waste conditions.
Performance evaluation of the system demonstrated its ability to accurately segregate waste with improved efficiency compared to manual sorting methods. The results indicate that the system can significantly reduce human effort, minimize environmental hazards, and enhance recycling processes. This study concludes that the developed waste segregation system is a practical and sustainable solution for improving waste management practices, and it holds potential for adoption in households, institutions, and small-scale industries.
