Revolutionizing waste management system through the development of an i-smart trash bin solid waste sorter

This study presents a structured approach to creating an efficient waste management solution capable of segregating papers, plastic bottles, and metal cans. Following a developmental research design, the study progresses through three main phases: design and construction, development and programming, and performance evaluation. In the design phase, this study integrates electronic components such as inductive proximity sensors, ultrasonic sensors, servo motors, LEDs, LCD, a buck converter with an Arduino ATMEGA 2560 microcontroller, and a backup power source from solar energy to operate each bin with an 11-gallon capacity. The development and programming phase implements a sophisticated waste management system using Arduino IDE, incorporating sensor inputs to classify and sort waste items accurately. Results showed an overall accuracy rate of 97% in waste segregation with a minimal error of 6%, where paper waste achieved 100% accuracy, while a 97% accuracy rate was seen in both plastic bottle and metal waste. These findings underscore the prototype's potential as a reliable waste management solution, contributing to more effective and sustainable waste segregation practices. Further enhancements can be explored to optimize functionality and usability, ensuring continued innovation in waste management technology.
