A cleaner and healthier benefits people so that clean air is important for people’s health and the environment, essential for making sure our cities are welcoming places for people to work and live. Therefore, it might be significant to control levels of air pollution and improve air quality.

This might be the world’s first intelligent biological filter to quantifiably improve air quality. This mossy living wall with the pollution absorbing power equivalent to hundreds of trees has been installed in some cities such as Berlin, Amsterdam, London and Newcastle upon Tyne and gradually it might also be increased to install in other cities around the world. As a background to create it, this is a response to research, which showed that approximately 9,000 Londoners and 50,000 Britons die prematurely each year due to respiratory, cardiovascular, and other illness associated with pollutants.

Mossy living wall in Newcastle upon Tyne

This mossy living wall can take up 1 % of the space that would be needed to produce the same air-purifying results using 275 real trees and it costs £17,600 to install. So, it can also reduce the required cost and space to plant real trees in urban space. Additionally, its structure can collect rainwater and automatically redistribute it using by solar panels and its system has also cooling impacts on surrounding area, helping to combat the urban heat island effect.

Key features of the mossy living wall

Mosses for cleaner air: Different types of moss bind environmental toxins such as particulate matter and nitrogen oxides while generating oxygen at the same time.

Cutting edge IoT (Internet of Things) technology: Integrated LoT technology delivers comprehends information on performance and status as well as environmental data on the City Tree’s surroundings.

Variable ventilation: Controllable ventilation technology allows to be intensified, meaning that the filter effect can be increased as required.

Optimum watering: Water supply is either connected or independent, thanks to a fully automated irrigation system.

Energy provision: Solar panels can provide energy.

Pleasant cooling effect: Mosses can keep large quantities of moisture and the considerably increased evaporation surface creates an enormous cooling impact.
