CityTree handles polluted air like 275 normal trees

City Tree

How about a green unit that has the same health effect on citizens as 275 urban trees do, but it only needs the space of just one tree? It is possible with the CityTree, a new patented system, developed by a German start-up.

Combine expertise in architecture, informatics, engineering and horticulture and you’ve got: Green City Solutions. This German company was founded in March 2014 by four guys with an ambition to develop highly efficient and sustainable solutions to improve the environment for the cityscape of tomorrow.

Now, the start-uppers already are multi-award winners. Their vision is seen and wanted by many cities in the world.

World wide solution

The company has a unique solution for a world wide problem. Every day 90 percent of cities’ inhabitants breathe polluted air which becomes the cause of every 7th death worldwide. The major components of air pollution are nitrogen oxides, ozone and especially fine dust (PM). At the same time the global population goes urban and in 2050 80% of world’s population will live in cities.

Green City Solutions addresses this global problem by combining a special, vertical installed moos culture, with an own developed Internet-of-Things (IoT) technology for its optimal maintenance. This patented product, the CityTree, is a four meter-high, three meter wide and 60 centimeters deep, freestanding unit.

Moss and vascular plants

It combines specific moss cultures with vascular plants. These eat particulate matter (PM), nitrogen dioxide and ozone; stuff we do not want to inhale. The plants filter 240 tons of CO2-equivalents per year in total. They can be adapted to any environment.

The construction contains sensors collecting environmental and climatic data, to regulate and control the unit and ensure that the plants survive. Thus, the CityTree has the same effect as up to 275 urban trees, but requires 99% less space and 5% of the cost. Thanks to solar panels and rain water retention systems, the unit requires only a few hours of maintenance per year.
