The R&D department of JCDecaux developed the Filtreo bus shelter in response to a study commissioned from the INRA (French national institute for agronomic research), which highlighted the possible impact of urban greening on air pollution. Filtreo is designed to reduce passengers’ exposure to pollutants, particularly fine particles, at the kerbside. This is where concentrations are highest.
FILTREO: A PATENTED INNOVATION COMBINING A NATURAL LIFECYCLE WITH TECHNOLOGICAL INNOVATION
The roof of the Filtreo bus shelter is actually a carpet of moss that captures and absorbs pollutants. As a particularly hardy plant without roots, the moss develops naturally over the long term, nourished by airborne particles. The roof also includes a built-in ventilation system that sucks air in through the plant layer and blows it out again towards the passengers at the bus shelter.
An intelligent control system activates the fans whenever pollution levels peak. These low-consumption fans could be powered by solar energy.
