A City Tree is… well… what you can see in the photo. It is made of Plants and Moss that have a high level air purification ability making them really effective in cities, as 1 City Tree equals 275 normal trees in urban areas! A City Tree can furthermore cool the area around it and has a self-contained solar panel on top to provide for its power. Furthermore, it has a water collection tank for rain thus allowing it to self-water its ‘cells’.

Each ‘cell’ of the City Tree contains only moss and plants; no soil whatsoever. But not just any moss! It is special moss that helps taking care of fine dust concentration and then uses said dust as means to give minerals to the plants, negating the need for plant fertilisers. For every climate/country/region/city, there are different plants and moss that need be used in order to reach optimum productivity with the City Tree and while so far that was not such a great problem now that there are people interested from other countries about the City Tree, serious research is in order.

With a team of four –an Architect, a Mechanical Engineer, an I.T. and a Horticulturist– the company was created in 2014 and had three years of difficulties as it was really hard to impress the market. It is only now that they have started getting more widely known and are receiving commissions.

Aside from all these incredible facts about the City Tree, here are some further interesting facts about them:

  • Most of the material used in making each City Tree comes from the Region of Saxony.
  • The QR Code on each City Tree can be used for marketing or educational purposes.
  • It has two benches!

Day 3 and it’s the 1st day of April and the knowledge trek is in full swing! The day started with a quick feedback session for our trainer Dr Schmiedgen and then quickly went on to further the newly developed Projects.

Deepening the participants’ knowledge Dr Schmiedgen told of the Business Model Canvas; its Function, its Field of Application and its Value Proposition. It is a tool through which the possible Pains and Gains of a Project can be mapped together with methods to alleviate or magnify them, a map of all the communication and revenue channels available to one and a list of the Key Activities, Types of Resources and Key Partners all rolled into one. For more information, feel free to go to

But there was more! Before the day was done and Dr Schmiedgen bade us ‘Goodbye’ and we all went to our Day’s Study Visit everyone had to go through the ‘Shark Tank’, namely the 90 secs Elevator Pitch. Everyone had to watch a short film with different approaches to the Elevator Pitch, get in groups of twos, prepare for 15 mins and then present their Project in precisely 90 seconds. Ready? GO!

“If you can put your ideas into 200 characters, you are good to go.” – Dr Peter Schmiedgen
