Mosses are an important ally in the fight against air pollution and global warming because they feed on airborne pollutants: Some mosses use the ammonia from vehicle emissions as a nutrient; others bind and metabolise fine dust. In addition, all mosses are small sponges since they also draw water from the air, they do well to absorb and store a lot of moisture if the humidity is high. Via this evaporation, a considerable cooling of the air occurs.
At Green City Solutions, we not only made the mosses viable in the cities by combining an active filter system with vertical moss mats and intelligent technology, and supplying them with their own bio-algorithm, but we also measurably improved quality of and cooled the surrounding air. The polluted, heated air gets actively sucked into and pushed through the filtering moss mats.
In addition to the air-purifying and cooling effects, the mosses are also good for the climate.
And that’s not all!
Since space in cities is limited, the moss filters have been equipped with smart additional benefits: they serve, for example, as a seating area in a fresh air zone or integrate free WiFi. Equipped with a large LCD screen, the moss filters CityTree
can be used as a digital advertising or information medium in the streets, on large buildings, during events or in shopping malls. To clean the air at a large scale, a free-standing wall element called WallBreeze
has also been developed.
