Many cities are finding
it hard to breathe

We’re doing something about it

Clean air in cities
worldwide

Here’s our solution

Air pollution

Pollutants such as particulate matter and nitrogen oxides have disastrous effects worldwide.

The idea –

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.

Living healthily with every breath

The global problem of highly polluted air in cities is a real one – even if it's more obvious in some places than in others. 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 air.

 

For a healthier future.
