The Problem
Urban waste management operations often rely on static collection schedules and manual coordination. This approach leads to:
- Inefficient routing and fuel waste
- Delayed collection of full bins
- Poor visibility of real-time bin status
- Manual driver assignment processes
- Lack of automation in operational alerts
To improve efficiency and responsiveness, a smart and event-driven system was required to monitor bin fill levels, automatically assign drivers based on proximity, and notify stakeholders in real time.
The Solution
BinWatcher was developed as a distributed microservices platform designed to simulate and manage intelligent waste collection workflows.
The system is built around an event-driven architecture where services communicate asynchronously using Kafka, ensuring scalability and loose coupling.
Core Capabilities:
- Real-time bin monitoring through simulated IoT sensors generating fill-level data
- Threshold-based alerting system triggering automated workflows
- Intelligent driver assignment based on proximity and availability
- Automated email notifications for assignment and unassignment events
- Centralized administration dashboard for managing bins and drivers
When a bin exceeds its fill threshold:
- An alert is published to a Kafka topic.
- The driver-assignment service analyzes location data and selects the nearest available driver.
- The system assigns the driver and publishes an assignment event.
- The notification service automatically informs the driver via email.
If the bin fill level drops below the threshold, the system automatically unassigns the driver and sends a corresponding notification.
