Citytree the panel able to reduce by 38% ultra-thin particles and by 17% black carbon
The panel, already in use in the largest international metropolises, is 4 meters high and covered with moss. Absorbs pollution and improves air quality
Citytree is the name of the mobile green innovation that is able to break down the concentration of fine dust and smog within a city.
It was tested as part of the European project "citytree Scaler", in which ENEA also took part.
How citytree works against pollution
During the tests at "citytree Scaler" - European project that aims to reduce pollution and improve air quality - It emerged that in the city of Modena - located in the most polluted area of Italy, the Po Valley - the device is able to reduce PM10 by up to 15%; but not only: the results show that ultra-fine particles decrease by 38% and black carbon by 17%.
It is a structure that has an autonomous and independent irrigation system, equipped with a specific system for rainwater collection, temperature and humidity detection, to ensure maximum efficiency and minimum water consumption.
The 3 meter long, 4 cm high and 60 cm deep mobile panel is covered with a rich variety of moss that can absorb up to 240 tons of CO2 per year in a surrounding area of about 200 square meters.
Citytree is ideal for all those cities with high pollution consumption that do not have many green areas and parks. In fact, in cities like London and Berlin, it has been installed both indoors and outdoors.
Between urban furniture and sustainability, to combat pollution
Citytree, for its innovative structure, combines urban furniture and sustainability, as it represents a plant filter with a power equal to 275 trees able to neutralize pollution and ensure clean air.
Felicita Russo, ENEA Researcher at the Atmospheric Pollution Laboratory states: "Technologies like citytree represent innovative solutions in continuous evolution and working on this area is one of the major interests of our laboratory. Certainly alone they cannot solve the problem of air pollution in the city, but they are still smart solutions to improve not only air quality but, more generally, the quality of life, protecting biodiversity, reducing the effects of heat islands and redeveloping the urban fabric with new places of aggregation"
