Vertical gardens prove effective in improving indoor air quality

Researchers at the University of Seville have demonstrated the effectiveness of active vertical garden systems in improving indoor air quality in buildings. To do so, they worked inside a closed glass chamber installed at the Higher Technical School of Agricultural Engineering, where they found that after 24 hours, 96% to 98% of the pollutants used in the various experiments had disappeared. The work is published in the journal Atmospheric Environment.
