Smart Waste Management: Enhancing Recycling through Automated Metal Detection and IoT Integration

Abstract

Abstract. Inefficient waste collection and contamination of recycling streams hinder efforts towards environmental sustainability. This paper presents the development of a Smart Bin that integrates metal detection and sorting functionalities that segregates metal from domestic waste. The system is designed to enhance recycling efficiency and support environmental sustainability. The system employs an ultrasonic sensor to monitor the fill level of the bin, while a load cell is utilized to measure the bin's weight, ensuring accurate tracking of waste accumulation. By integrating the system with the Internet of Things (IoT) platform Blynk, real-time monitoring and warning capabilities are made possible. This integration allows the Smart Bin to send instant updates on its fill level and weight, ensuring timely waste collection and preventing overflow. Thus, metal waste is automatically identified, separated, and reported, facilitating safe and efficient metal recycling. This paper details the design and development of the Smart Bin system, exploring its potential to contribute to a more sustainable waste management approach. The study highlights the potential of Smart Bin technology to support green initiatives and contribute to more sustainable urban environments.
