City Tree – Modules to absorb urban pollution
A short description of the NBS project
A Berlin-based company has launched an urban air filter which it calls a “CityTree”. The unit includes a screen of moss and other plants that its maker says offers the same environmental benefits as 275 trees.
In an innovative way, the CityTree combines the natural abilities of mosses with intelligent IoT technology. The cost-effective, low-maintenance and flexibly implementable biofilter improves the quality of life in cities considerably.
