Passive particle traps

3D modeling and artificial intelligence

Call for projects from ADEME (AQACIA)

2021 – 2023

10 ha

Determine the best location for an experiment of particle traps in the city and evaluate their performance on a large scale


The French Environment and Energy Management Agency (ADEME) launched in 2020 a call for projects named AQACIA (Improvement of Air Quality: Understand, Innovate, Act). AIR&D responded to this call for projects alongside TrapAparT (SICAT) and ICPEES (Institute of Chemistry and Processes for Energy, Environment and Health – CNRS) and the team was awarded the project.

Within the framework of this project, the partners of the AQA3P project are developing and operating prototype passive traps (operating without energy input) to abate fine particles in the vicinity of major urban traffic routes in order to improve air quality in these areas which combine worrying pollution levels and high population density.

In this project, AIR&D is responsible for modeling the abatement of fine particles by the traps using 3D modeling and artificial intelligence in order to guide the conduct of on-site experiments and to evaluate their performance on a larger scale.
