IoT systems for advanced urban waste management: RFID tracking, logistics optimization and data intelligence

Urban waste management is undergoing a radical transformation thanks to the adoption of IoT technologies and intelligent tracking systems. One of the most promising tools in this context is the use of RFID tags applied directly to bags or containers. This technology allows to identify each individual disposal, assigning it uniquely to a user, tracking its weight, frequency and compliance.

The main advantage is twofold: on the one hand, it is possible to obtain pay-as-you-throw systems that are fairer and more incentivizing; on the other hand, it opens up the possibility of optimising collection routes thanks to real-time data, also obtained from environmental sensors positioned on the bins, which signal the filling level or anomalous conditions.

The combined use of mobile RFID antennas (on board the vehicle) and fixed ones (on columns or strategic points of the city), together with devices capable of collecting and sending data to centralised platforms, also allows for the analysis of the entire disposal and handling cycle, improving the efficiency and transparency of the processes.

From an engineering point of view, RFID systems applied to waste collection require well-calibrated integration between:

- Passive tags on bags (UHF, EPC Gen2) resistant to hostile environmental conditions;

- Mobile RFID readers on board vehicle, synchronized with GPS systems to geolocalize each reading;

- Fixed stations equipped with RFID readers and NB-IoT or LTE-M connection for sending data in real time;

- Low-consumption microcontrollers for local control of events and temporary storage;

- Backend server with aggregation, verification and anomaly detection algorithms for the collected data;

- Intelligent dashboards for operators and public administrators, with live viewing and historical reporting.

The system can also be extended with modules for reading QR codes for special deliveries, or with digital scales for weighing at the time of collection.
A well-designed architecture must also include the management simultaneous monitoring of tens of thousands of tags and a robust and scalable network infrastructure.
