Abstract-:The exponential rise in plastic waste, particularly from single-use PET bottles, presents a critical challenge to environmental sustainability. Conventional recycling approaches are often hindered by inconvenient manual processes, limiting public engagement. To counter this, the proposed Smart Reverse Vending Machine (RVM) offers an automated, user-friendly solution for the collection and preliminary sorting of plastic bottles. The system employs an Arduino Uno microcontroller, an IR sensor, and a load cell with HX711 amplifier to detect, validate, and weigh deposited bottles. In exchange, users receive immediate incentives such as coins, fostering responsible waste disposal habits. Designed with affordability and scalability in mind, this compact system is ideal for installation in high-traffic areas like malls, transport hubs, and educational campuses. The initiative aims to enhance recycling participation through real-time rewards and minimal operational complexity. Potential future enhancements include IoT connectivity, AI-based recognition, and digital rewards, positioning the system as a smart and sustainable waste management solution.
