Fabrication of Reverse Vending Machine

The Reverse Vending Machine (RVM) now becomes an automated plastic waste collection system with the user being rewarded for returning plastics bottles. This paper is focused on the design and implementation of an affordable miniaturized semi-automated Reverse Vending Machine (RVM) which detects bottle existence using ultrasonic sensor, verify the bottle weight with using load-cell setup and stores valid bottles in an in-house collection bin. When a good accept is given, a candy will thrown as the reward. This prototype is driven by an Arduino microcontroller, which collects information from the sensor, controls the dosing unit and all functions including the three LEDs and the buzzer.The prototype is a response to the growing threat of plastic pollution, and aims to fuel a culture of recycling in schools, colleges and public spaces.
