Background

The City of Hürth relied on fixed collection routes for public waste bins, but actual fill levels varied widely across locations. As a result, half-empty bins were emptied unnecessarily while critical points overflowed, leading to wasted mileage, higher operating costs, and increased complaints due to “wild garbage.” The municipality recognized that manual, experience-based scheduling was no longer efficient or reliable. A data-driven solution with real visibility and predictive logic was required — one that could support precise route planning, reduce wasteful trips, and remain cost-effective, robust, and fast to deploy. This requirement triggered the project.

Challenges

Rigid collection routes

Trucks followed fixed schedules instead of responding to actual bin fill levels.

Limited bin-level visibility

Half-empty bins were emptied while overflowing bins went unnoticed.

Increasing illegal dumping

Overflowing bins led to more uncollected waste and citizen complaints.

Lack of scalable sensing

The city required cost-efficient sensors that deliver accurate, consistent data outdoors.

Solution

To tackle overflowing bins and inefficient collection, Stadtwerke Hürth AöR deployed 250 Milesight EM310-UDL Ultrasonic Distance Sensors in key public waste bins, connected via a hybrid LoRaWAN® network combining Helium community gateways with a few municipal UG65 gateways.

A federated AI model provided by dataMatters GmbH analyzes location-specific factors — including proximity to train stations, bus stops, kiosks, and snack bars — to predict fill levels for the next day. The system dynamically optimizes waste collection routes, ensuring trucks service only the bins that need attention, improving operational efficiency and reducing citizen complaints.

Results

The deployment of Milesight's EM310-UDL sensors in Hürth's waste management system has delivered measurable improvements:

Reduced Carbon Footprint and Optimized Routes

Predictive AI combined with precise sensor data reduced collection kilometers by up to 21% per week, lowering fuel use and CO2 emissions. Staff now follow demand-driven routes instead of fixed schedules, which reduces stress and improves job satisfaction.

Reliable Outdoor Performance

Long battery life, IP67 protection, and seamless LoRaWAN® integration ensured stable operation in diverse outdoor conditions, including rain, dust, and temperature extremes.

Scalable Deployment

Compatibility with existing infrastructure (Helium + UG65 gateways) and standardized data formats enabled rapid scaling, flexible sensor placement, and minimized CAPEX, supporting quick city-wide rollout.

Replicable and Privacy-Conscious

Federated AI enables predictive models to be shared with other municipalities without exposing sensitive data. Milesight's sensors integrate reliably with existing systems, ensuring smooth replication in new deployments.

Why Choose Milesight
