Our CEO Peter Sänger in the OECD Forum Network
In “𝗛𝗮𝗿𝗻𝗲𝘀𝘀𝗶𝗻𝗴 𝘁𝗵𝗲 𝗻𝗮𝘁𝘂𝗿𝗮𝗹 𝗽𝗼𝘄𝗲𝗿 𝗼𝗳 𝗺𝗼𝘀𝘀 𝘄𝗶𝘁𝗵 𝗜𝗼𝗧 𝗳𝗼𝗿 𝗰𝗹𝗲𝗮𝗻𝗲𝗿 𝗮𝗻𝗱 𝘀𝗺𝗮𝗿𝘁𝗲𝗿 𝗰𝗶𝘁𝗶𝗲𝘀”, the OECD Forum Network has published our CEO’s thoughts on moss, clean air and Green City Solutions’ active biofilters.
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.
According to tests with independent institutions, such as the TROPOS Institute for Tropospheric Research in Leipzig or the Institute for Air and Refrigeration Technology in Dresden, the active biofilters are able to clean up to 82% of fine dust from the air and cool the air by up to 4°C via evaporation.
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 or CityBreeze 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.
The OECD Forum Network is a “space to exchange knowledge and ideas, and co-create policy solutions to a wide range of social, economic and environmental challenges”. Here you could find “experts and thought leaders […] to discuss and develop solutions now and for the future”.
