The Municipality of Athens has contracted an integrated cleansing management system that will put 12,100 RFID tags on its waste bins and 145 RFID readers on its refuse collection vehicles, alongside on-board weighing, fill-level sensors and telematics across a fleet of 360 vehicles. The programme is described by its subcontractor as the largest IoT-based waste management digitisation project undertaken in Greece to date.
One caveat matters before the numbers: the municipality’s own project page places this sub-project at Phase 1, the implementation study, with a pilot operation scheduled before full production rollout. The equipment counts below are contracted scope, not an installed base. Nothing here says 12,100 tags are already on bins in the street.
Who is building it
The system is being delivered by the OTE Group, the Hellenic Telecommunications Organization and Greece’s largest telecoms group, with EmDoT SA as subcontractor. EmDoT is an Athens-headquartered technology company that develops IoT platforms for waste management, oil and gas supply chain management and roadside assistance. The delivery sits on OTE’s e-track platform combined with EmDoT’s waste subsystems, marketed as Dot.Waste, Dot.Weighing, Dot.SmartBins, Dot.Platform and Dot.Capacity Management. The municipality states the programme is being run to PRINCE2, which suggests a formal stage gate before the pilot converts to production.
The hardware, in full
- 12,100 RFID tags fitted to waste bins, each carrying a unique identifier read automatically at the point of collection.
- 145 RFID readers fitted to refuse collection vehicles for bin identification.
- 360 vehicles fitted with GPS and telematics units covering position, speed and fuel monitoring, integrated with the municipality’s traffic office despatch system.
- 50 vehicles equipped with weighing systems built into the bin lifting mechanism, recording a weight per bin into the central database.
- 1,000 wireless fill-level sensors in bins, reporting waste level in real time to feed dynamic routing.
- In-cab terminals for drivers and crews to receive instructions from the control centre, plus an Android and iOS app carrying maps, notifications and job instructions.
- Central platform comprising cloud servers, the fleet and cleansing management application, a business intelligence layer of dashboards, KPIs and reports, and APIs for interoperability with the municipality’s existing systems.
The ratio of 145 readers to 12,100 tags is the interesting number. A bin identification system only pays back when the reader is on the vehicle rather than in the depot, because the read has to happen in the two or three seconds the lifter arm is in motion. Athens is fitting readers to a subset of the 360-vehicle fleet, which implies the tagged bin stock is served by specific rounds rather than by whichever vehicle happens to be passing. That is a normal design, but it makes round allocation and reader availability an operational constraint the municipality has to manage, not just an IT one.
What a bin identification system actually delivers
For readers coming to this cold: putting a tag on a bin and a reader on the lifter gives you a timestamped, geolocated record that a specific bin was emptied by a specific vehicle. Pair that with the lifter weighing and you get a weight against that same bin. From there you can prove service delivery, chase missed collections with evidence rather than assertion, measure recycling capture by street or by property, and, if policy allows it, bill on the basis of what a household or business actually presented. EmDoT states that Dot.Waste supports Pay-As-You-Throw models and compliance with EU Waste Framework Directive 2008/98/EC, though the Athens documentation published so far frames the benefits in operational and environmental terms rather than as a charging scheme.
The frequency question the paperwork does not answer
Neither the municipality nor EmDoT has published the air interface frequency of the 12,100 bin tags, and it is worth understanding why an RFID reader would want to know. Frequency choice drives the physical build of the whole installation. A sub-135 kHz system tolerates dirt, moisture and the metalwork of a lifter arm well but works at short range, which forces the antenna onto the comb or the lifting arm itself, close to the tag, and makes the harness a wear item on a machine that cycles hundreds of times a day. A UHF system reads at much greater distance, which allows the antenna to be mounted on the vehicle body away from the mechanism, but it is more sensitive to the reflective environment of a steel hopper and more likely to read a bin that is standing nearby rather than the one on the lifter. Both approaches are in service across European municipalities and both can be built to EN 14803 or DIN 30745, the standards that cover bin identification and RFID data exchange; conformance to either never implies a frequency, since they span both sub-135 kHz and 868 MHz. Until Athens publishes the technical specification, the mounting design and the read reliability targets are the parts of this contract worth watching.
Budget and funding
The two published budget figures do not match, and both are worth recording. The Municipality of Athens gives the sub-project budget as EUR 1,733,149.78 excluding 24% VAT, or EUR 2,149,105.73 including VAT. EmDoT, in its announcement of the partnership on 11 July 2025, gives a project budget of EUR 1,695,059.35 with EUR 844,028.20 of European Union funding. Neither document reconciles the difference, which most likely reflects different scope boundaries or a contract value against a funded value.
The money comes through the “Development of Digital Products and Services” programme of the National Recovery and Resilience Plan Greece 2.0, the Greek government’s recovery plan funded by the European Union’s NextGenerationEU instrument, which has been a significant driver of municipal IoT procurement across Greece since 2021.
On results, EmDoT’s own material reports up to a 20% reduction in operational costs from its solutions, and cites 1,000 smart bins in operation with a 12% reduction in overfilled bins and no increase in route duration or distance. Those are the vendor’s figures rather than independently verified Athens outcomes, and the Athens deployment has not yet reached a stage where it could produce its own.
Greek outlet TA NEA reported on 22 July 2026 that 20 new vehicles had entered the municipal cleansing fleet fitted with GPS and a system for reading identification cards on the blue recycling bins, so bin identification is already being exercised in the field ahead of the full 12,100-tag rollout.
