Smart. Clean. Sustainable.

Innovation at the service of Smart Cities.

We aim to have an impact on the environment and the quality of life.

To this end, we make the most advanced technologies transparent and easy to use for our clients. Our onboard intelligent vision measures city cleanliness with unrivalled accuracy, data is automatically made available via edge-to-cloud technologies, and we provide tools to obtain results from all such data. These innovations have been developed together with our partner cities, associations, universities and technology companies.

Clean City Index

An objective measure of cleanliness.

How is it possible to objectively assess the cleanliness of a place? The Clean City Index translates the perception of local residents through a score of 0 (dirty) to 5 (clean). With more than 20 years of experience, it can identify both the causes of dirt and the means to clean it. Learn more →

AI & Computer Vision

Bicycle equipped with Cortexia vision system

Different types of waste are detected and counted by artificial intelligence algorithms (CNN – Deep Learning). The smallest waste detected is a cigarette stub.

Depending on the geographical coverage required, measurement systems are installed on different types of vehicles: commercial vehicles, public transport, bicycles, etc. An app can be used to supplement index readings or report anti-social behaviour.

IoT, Edge to Cloud

Vehicles are equipped with a camera and a Cortexia-Box, which processes images directly on the vehicle (privacy-preserving). Data — waste types and quantities, position, time — is automatically transmitted via LTE to the cloud.

Cortexia-Box — onboard edge-to-cloud processing

Easy access to real-time data

Cortexia web interface — cleanliness data visualisation

The entire process, from measurement to data visualisation, is encrypted and monitored continuously. It requires no client infrastructure.

Results are visualised through a web interface. Data in GIS map form or curves over time, by location or type of waste, enable accurate diagnostics. Alarms are triggered for critical waste or dirt levels.
