Sustainable businesses are on the rise and it's hard not to understand why. In addition to the tempting incentives that governments are offering, consumers have also become more aware and tend to choose more and more companies.eco friendly. Not to mention the fact that technology is moving in this direction in the long term (it has to if we are to survive). The more companies decide to go green, the technology becomes cheaper and more practical, making the economic incentive even stronger. We collected six young businesses andstart-upsThey are seizing the moment and changing the world.
Considering that trees and plants are capable of absorbing pollutants, this became the starting point for GCS. They were especially fixated on moss as certain strains are especially good at neutralizing pollutants like nitrous oxide and ozone until they are introduced into their own biomass. Combining this natural property with state-of-the-art technology they have created City Tree. It is a facility slightly larger than a billboard, which can be placed anywhere in the city and is equivalent to 275 trees, reducing pollution by 30% in a radius of up to 50 meters.
The most important thing is that a single specimen can absorb nitrogen dioxide and airborne particles as 275 natural trees would, feeding on the pollutants it captures, report its young creators.
Lacking trunk, branches and foliage, this "tree" is a type of green wall created with biotechnology whose key to its surprising performance lies in the plant matter that forms it: the moss, and its intelligent design.
This particular green wall concentrates the advantages of a small forest thanks to the technology of its manufacture: moss plates that do not require soil, arranged on a mobile structure that can be placed on sidewalks or squares and help to improve the environmental quality of the city.
The moss filters the air and placed in the 2.8 meters per side panel designed for this purpose, it can absorb 250 grams of suspended particles per day, capture up to 240 metric tons of CO2 per year, and transform them into nutrients or biomass.
Each City Tree can reduce air pollution by up to 30% in a 50-meter radius, with 99% less soil and 95% cost-effective, says D. Honus, CEO and co-founder of the company that developed this novel “tree”, Green City Solutions (GCS).
Among the properties of this novel tree is the speed of creation -in just six hours it can be installed-, it is easy to maintain because it has its own irrigation system taking advantage of rainwater, and it is operated with electricity obtained from solar panels.
How does it work
It also uses Internet of Things technology to collect and analyze data on air quality and the condition of the City Tree itself. The company has also used this idea for other circumstances, including a pollution-swallowing music school in Krakow, Poland, in which the roof is covered by these types of bushes.
The sensors installed in the green panel measure and regulate the humidity of the soil, temperature and water, other sensors measure the quality of the air and evaluate the performance of the installation.
The creation of each new “tree” responds to the climatic and environmental conditions of the selected moss species and its adaptation to the city in which it will be placed. To date 25 cities in various countries already have copies of City Tree.
These environmental, technological, time advantages (it is not necessary to wait years for the vegetation to cover its environmental functions) and other properties such as the small space it occupies, make each City Tree cost up to 28 thousand dollars per decade, that is, , almost 30 times more than a natural tree.
Among the criticisms that this measure to combat pollution receives is its high cost and that it is limited to the effects of pollution. On the other hand, as it only impacts 50 meters away, it is seen as a very small "solution" compared to the serious environmental problems of cities that continue to spread.
Although City Tree does not equal an authentic tree, neither in its natural beauty, shade, freshness, or as a niche for birds and other types of life, given the interest of companies and people, the company works on different versions and sizes of this installation green that can be placed inside homes and in other types of spaces.
Meanwhile cities such as Paris, Oslo, Brussels, Glasgow and Hong Kong already have their own City Trees, intelligent trees that feed on and usefully digest the pollutants around them.
