A Smart E-Waste Collection Bin With Blockchain Based Token Incentivization

Abstract

Electronic waste (e-waste) management is a critical environmental challenge, particularly in developing countries like Uganda. This project presents an innovative approach to e-waste management by leveraging Internet of Things (IoT) technologies to monitor and manage e-waste collection efficiently. Our system integrates ultrasonic sensors, the ESP8266 Wi-Fi module, and the Arduino microcontroller to create a real-time e-waste bin monitoring solution. The ultrasonic sensors measure the fill levels of e-waste bins, transmitting the data to a central server via the ESP8266. The server, developed using the Laravel framework, processes and stores the data, providing real-time visualization through a web-based dashboard. This allows for timely monitoring and management of e-waste bins. Further- more, the system incorporates a token Incentivization and redeeming mech- anism to encourage proper e-waste disposal. Users receive reward tokens for disposing of e-waste, which can be redeemed for cash or cryptocurrencies. To enhance the security and transparency of the system, blockchain tech- nology is employed for record-keeping. Every transaction related to e-waste disposal, token issuance and redemption is securely recorded on the blockchain, ensuring an immutable and transparent record of all activities. This not only builds trust among users but also prevents fraudulent activities. Additionally, the notification system, utilizing Africa’s Talking SMS API, alerts recycling companies when bins approach full capacity, ensuring prompt collection and preventing overflow. This project not only streamlines the e-waste management process but also promotes environmental conservation by incentivizing proper e-waste disposal. The successful implementation of this system demonstrates the potential of IoT and blockchain in addressing real-world environmental chal- lenges, offering a scalable and cost-effective solution that can be adapted in other regions facing similar issues. This integration of IoT, blockchain, and token-based incentives highlights a comprehensive approach to sustainable e-waste management, aiming to improve recycling rates and reduce environ- mental impact. i
