A Proposed IoT Based Smart Waste Bin Management System with An Optimized Route: A Case Study of Ghana

Waste management in Ghana has in recent times been a subject of discourse that pervades most of its industrial cities. The provision of waste bins at vantage points by waste management institutions is not enough to solve the problem of the current management system. In this paper, a proposed method that uses multiple solutions to address the issues of spillage and inefficient collection scheme is presented. The system provides a monitoring platform for the waste management institution to handle the alert records by creating orders for the garbage collectors/drivers which can be accessed via a mobile application system. The proposed system includes a smart waste bin which has a microcontroller-based system constructed and affixed to the top of the bins to detect bin level status and communicate to drivers and management office via SMS and application system. A work order is created once a utilizes is full which can be received by the drivers and routing system regarding the state of bins distributed within a specific geographic area that can be assessed on the drivers' phone. The system implantation works successfully, making it possible to monitor waste bin status in real-time but occasionally had high latency which was primarily due to the use of GSM module for GSM/GPRS connectivity.
