The CityTree: Improve Air Quality With Moss by Green City Solutions

More than half of humanity lives in cities – and the trend is rising. Cities are clearly the living space of the future. And yet our most important resource, the air we breathe, is in many places so polluted that breathing is harming our health.
In the future we have in mind, fresh air in urban areas is available to everyone. That’s why we’ve developed the world’s first bio-tech filter to quantifiably improve air quality: The CityTree.
The CityTree combines natural moss filters with smart IoT technology. The result is perceptible fresh & clean air. As a shade giving, green oasis it creates a place of relaxation and interaction and enriches every urban space. The CityTree is the world’s first biotech fine dust filter for urban spaces.
Integrated moss modules bring the forest into the city and ensure that the air is verifiably and noticeably clean. We combine the natural filtering power of mosses with smart IoT technology.
With an automated irrigation and ventilation system, the CityTree can clean and cool the surrounding air. Independent studies show that up to 82% of the fine dust in the air is filtered directly through the moss and the air is also cooled by up to 2.5 °C.
Polluted air, and especially the fine dust it contains, attacks all human organs, leading to everything from heart and lung problems to dementia, cancer and skin diseases. Regarding Covid-19 studies indicate a clear correlation between fine dust pollution and higher mortality rates of Covid-19.
Cardiovascular or respiratory diseases caused by fine dust increase the risk of heavy Covid-19 diseases enormously. According to a comprehensive study by the Max Planck Institute air pollution could be a co-factor in 26 percent of Covid-19 deaths in Germany. Worldwide, they put the proportion at an average of 15 percent.
Moss has the natural ability to bind and metabolise fine dust. Additionally, mosses cool the ambient air by evaporating water on their enormously large leaf surface. These abilities can be used optimally for local improvement of air quality and make moss a sustainable regenerative fine dust filter with cooling effect. We bring nature back to the city and use our technologies to ensure the well-being of mosses and people.
