Quick Facts
The company Green City Solutions helps people in highly pollu-ted places to enjoy cleaner air and thus a better health and qua-lity of life. The biotech filters CityTree and CityBreeze developedfor this purpose combine a wide range of applications to makeideal use of urban space.
The basis of Green City Solutions is the idea of combining na-ture with digital technology. It utilizes the outstanding naturalability of living moss to filter fine dust and cool the ambient air.The interaction of sensors, intelligent ventilation, irrigation andsoftware makes the natural cleaning power of moss usable andmeasurable.
About the CityTree
The CityTree is a combination of street furniture and biofilter - a benchat the bottom, a moss-covered surface at the top, and complex tech-nology with an IoT interface inside. This opens up further applicationpossibilities, e.g. in the areas of smart city, (e-mobility) infrastructureand communication.
About the CityBreeze
The CityBreeze combines natural air filtration with digitalpresentation technology. On one side there is a green, vitalizingmoss wall with active filter technology and on the other a 75“ LEDscreen. The combination, unusual at first glance, makes sense: bothinformation and advertising as well as the selective improvementof air quality is placed where as many people as possible react andbenefit.
The active moss filters can remove up to 82% of fine dust from the air, measurably improving the air in the immediate vicinity
The performance and effect parameters were evaluated in extensive scientific measurements
Environmental performance can be detected, evaluated and controlled through the use of sensors
The CityTree is never „full“, as the fine dust is converted to natural biomass by the moss
Mosses thrive under controlled conditions in the moss farm up to 16x faster than in nature

The problem of air pollutionand the natural filter power of moss
Air pollutionIn the discussions about the global environmental problem of air pollution, the term „fine dust“ if often used. Fine dust refers to solid or liquid parti-cles that float through the air for a certain amount of time. Depending on the size, a distinction is made between PM10 (10 μm), PM2.5 (2.5 μm) andultra-fine particles (0.1 μm). These particles enter the human body through the respiratory tract and can cause disease and death.
The filter power of mossAir pollution is a complex problem and its fight requires the interaction of many players. Due to long planning and implementation phases, it is difficult for companies and cities to actually implement certain measures. That is why short-term air quality improvements play an important role.
FINE DUST GENERATORS
The Federal Environment Agency of Germany estimates that the local dust pollution mainly stems from the emissions from diesel vehicles and the dust swirled up by traffic.
AIR QUALITY IMPROVEMENTS
Cities and companies have several options to counter fine dust pollution - but these often require long planning and implementation phases.
HEALTH IMPACT
Depending on the particle size, fine dust penetrates the body to different depths, which can trigger a wide range of diseases, the most common are lung and cardiovascular diseases.
THE FILTER EFFECT OF MOSS
The ability of moss to bind fine dust and metabolize makes it the most sustainable and regenerative fine dust filter.
COMPOSITION OF FINE DUST
Fine dust consists of a complex mixture of solid and liquid tiny particles and is harmful to humans from a diameter of less than 10 micrometers.
FINE DUST FILTERS IN COMPARISON
Fine dust filters can help to improve the air quality in the city hot spots for citizens and employees. The CityTree’s moss has regenera-tive and carbon-neutral properties.

S. 11/10
The moss surface is comparable to the human lung. It isenormously absorbent due to the fine, thin leaflets. Thus,the 2 respectively 4m² of moss used in the CityBreeze andCityTree correspond to an active moss surface of 60 re-spectively 120m², which can absorb fine dust from the air.
The fine dust has a negative electrical charge and is at-tracted and bound by the positively charged moss surface.Most of the „prey“ is metabolized and biodegraded by mi-croorganisms and rendered harmless.
SUPERHERO MOSS
Mosses are capable of astonishing things: They bind finedust, some are antiseptic, antiviral and fungicidal; true all-rounders for air pollution control and health. With theinterplay of sensors, intelligent ventilation, irrigation andsoftware, we can increase their natural cleaning power andmake it usable and measurable.
A PIECE OF NATURE
Various moss species grow in the moss filters that can absorb and metabolise finedust. At the same time, they produce valuable oxygen and lower the air tempe-rature.
PLEASANT COOLING
Due to their enormous surface area, mos-ses store and evaporate large amounts ofmoisture. This leads to a cooling effect byup to 4°C and noticeably fresher ambientair .

How the CityTree worksThe way the CityTree works can be broken down into 4 steps:
The CityTree in numbersThe following key data serve for a better understanding of the CityTree:
SECRET SAUCE
The CityTree is the world’s first Bio-tech fine dust filter for urban spaces. With the integrated mosses, it brings nature into the city and ensures that the air is verifiably clean.
FUNCTIONALITY
Mosses are natural fine dust filters. Combined with smart IoT technology, an intelligently controlled irrigation system and ventilation, CityTrees clean and cool the surrounding air.
PROVEN IMPACT

In order to set up the CityTree, three steps are carried out: First we select a potential location based on desirability, then we check for its technical feasibility, and finally we customise the CityTree according to the use case.
Location attractivenessSelection of CityTree locations based on the criteria of air quality, quality of stay (user experience) and visibility.
Location feasibilitySelection of CityTree locations based on the criteria of air quality, quality of stay (user experience, attention) and data coverage.
Adaptation of the CityTreeThe CityTree experience can be enhanced with 4 different add-on packages: Connectivity, Communication, Infrastructure & Relaxation
ENVIRONMENTAL PERFORMANCEBy identifying locations with particularly high levelsof particulate matter and urban heat islands, theCityTree can be used where it is needed most.
QUALITY OF STAYWe create a place that invites to relax and take a deep breath. We therefore consider a wide range of external factors that influence the quality of stay.
VISIBILITYCityTrees not only improve air quality, but also offer a platform for media communication and human interaction with the right choice of location.
STAKEHOLDERDepending on the application, different stake holders should to be included in the installation. We help to ensure that all associated parties are involved.
APPROVALSBased on the use case, various permissions are required to set up CityTree. It is important to distin-guish between private and public terrain.
COMMUNICATIONWe help to tell your CityTree story in a way that at-tracts attention and is in line with your sustainability strategy and to educate citizens.
