1. The aim of the project is to create a technological infrastructure to gather the services for the city in a single point, to optimise the use of energy, environmental, economic and IT resources. After the construction of the first outdoor prototype and its experimentation in the municipality of Castel Bolognese which started in October 2018, in 2019 the second prototype called PUNTOnet waste was built: an automated separate municipal waste collection center 2. The PUNTOnet waste system can be integrated with other infrastructures such as bus shelters, bicycle shelters, e-bike recharging stations, and with technological totems. This modularity enables the integrated provision of multiple smart services 3. Smart cities: Environmental sensors: The sensor network that monitors the main air quality parameters installed in the municipality of Castel Bolognese collected data on an hourly basis throughout 2019. These data show a seasonal variability linked to both climatic factors and human activities. In order to understand in detail the weight of each emission source (heating and traffic) in the urban environment, the data collected were processed with weather data, road traffic data and energy consumption data using advanced machine learning techniques.
