As part of a pilot project to improve air quality in Ludwigsburg, filtration expert MANN+HUMMEL has donated a CityTree to the city. With the CityTree, MANN+HUMMEL would like to test sensors for fine dust or other harmful gases, in order to use them in future digital products.
Urban living spaces are increasingly exposed to environmental pollution. Together with partners from the Living Lab innovation network of industry, science and administration, the City of Ludwigsburg is pursuing various projects to improve air quality in Ludwigsburg. In several trials, the network partners and the Department of Civil Engineering and Green Areas want to examine the extent to which mosses can contribute to improving air quality.

The City Tree developed by Green City Solutions GmbH is a mobile and smart biological air filter that combines air-purifying mosses with Internet of Things (IoT) technology. The moss protected by cover plants is supposed to bind fine dust, produce oxygen and cool the air. Using Internet of Things technology (IoT), environmental data can be collected in real time and combined in a cloud. In addition, the CityTree has an irrigation system. A built-in tank enables self-sufficient water and nutrient supply. The CityTree is also equipped with its own energy supply system. Installed solar panels generate energy for operation, which can be stored in batteries.
The network partners tested the effectiveness of the CityTree in its surroundings in the middle of the city and also checked whether the moss filters CO and other possible harmful gases from the air. The needs of the plants are also the focus of the analyses.
