it hard to breathe

We’re doing something about it

What we’re doing about it

The perfect combination
of plants and IoT

Certain moss cultures have the ability to filter pollutants such as particulate matter out of the air by binding them to the leaf surface and then integrating them permanently into their own biomass. This makes them ideal air purifiers. But in cities, where air purification is a great challenge, mosses are barely able to survive due to their need for water and shade. The combination of shade-giving plants, a fully-automated supply of water and nutrients and cutting-edge Internet of Things technology (IoT) can solve this problem. At the same time, the filter performance and the plants’ requirements can be measured and analysed. Put it all together and you have an intelligent, natural air filter for cities: the CityTree.

Here’s what the CityTree can do

This is the CityTree

With the environmental benefit of up to 275 normal urban trees, the compact and mobile CityTree improves the air measurably, cools it and protects the environment from noise.

So cities can breathe again

The global problem of highly polluted air in cities is a real one – even if it’s not always immediately obvious. People who live in cities, and by the year 2050 that will be 80% of the world’s population, are particularly affected. With the CityTree we want to make these cites into places that are good to live in. With clean and cool air. For a healthier future.
