PURETI: artificial grass that improves air quality

Domo® Sports Grass introduces a new line of artificial grass products powered by PURETi that improve air quality.

Air pollution is responsible for 7 million deaths worldwide every year.

What is PURETi

PURETi is a photocatalytic nanotechnology that, once activated by UV or sunlight, starts a chemical process that uses oxygen (O2) and humidty (H2O) in the ambient air to generate Hydroxylradicals (OH-) and Superoxide-anions  (O2-). These are powerful cleaning agents that convert air-polluting molecules such as NOX, SOX and VOCs into harmless components.

PURETi is the only photocatalytic product tested with success in the consortium of ISCAPE https://www.iscapeproject.eu/about/consortium, the ambitious European Horizon 2020 project that aims to reduce the ecological footprint of European cities and improve air quality. By integrating PURETi to the production process of artificial grass, Domo® Sports Grass is able to reduce NOX by 70%. 

How does PURETi work?

Traffic, industry and agriculture generate NOX and VOC Traffic, industry and agriculture generate Nitrogen Oxigens (NOX) and Volatile Organic Compounds (VOCs) which form an important part of particulate matter that, according to research by the WHO (World Health Organization), is responsible for 7 million deaths worldwide every year. In addition, nitrogen compounds also threaten the biodiversity of nature reserves.

Activated by sunlight PURETi starts a chemical process that uses oxygen (O2) and humidity (H2O) in the ambient air to generate 2 powerful cleaning agents:

  • Hydroxylradicals (OH-)
  • Superoxide-anions (O2-)
PURETi converts water molecules in the ambient air into hydroxyl radicals (OH and O2)
O2 radicals convert NOX into mineral nitrates Superoxide-anions (O2-) oxidizes NOX into harmless mineral nitrates that are consumed and recycled by plants.
Hydroxylradicals (OH-) turn VOC into water steam (H2O) and a small / residual amount of CO2. OH-radicals convert VOC into water steam (H2O) and a small / residual amount of and CO2
The Air purifying efficiency of PURETi on 1 m2 of artificial grass can be related to 1 fully grown tree    

The air-purifying efficiency of PURETi on 1 m2 of artificial grass from Domo® Sports Grass can be compared to 1 mature tree.

An artificial turf football pitch powered by PURETi neutralizes 188 kg NOx per year, which corresponds to the NOx emission of 200 Euro 5 cars that run 20 km a day for a year.

PURETi is now available on following products:

Benefits

  • Improvement of air quality
    According to the World Health Organization (WHO), air pollution is responsible for 7 million deaths worldwide yearly. Artificial grass powered by PURETi reduces up to 70% of harmfull NOX.
  • Antibacterial
    Due to the photocatalytic oxidiation PURETi is a new and innovative way to keeping sports pitches free of mould, moss and algae and results in a big reduction of the costs on maintenance.
  • Ecologic 
    Artificial grass powered by PURETi no longer needs treatments with biocides or other products to keep them free of growth of mould, moss and algae.
  • Durable 
    Artificial grass powered by PURETi has an increased UV stability and outperforms all other artificial grass qualities in terms of durability.
  • Odor elimination
    PURETi oxidizes organic components and maladors at molecular level. Thanks to artificial grass powered by PURETi you will smell the freshly improved the air quality.

Research

Research shows that an artificial grass football pitch powered by PURETi neutralizes 188 kg NOX per year, and it also demonstrates that the air-purifying effect increases with surface area. This corresponds to the NOX emission of 200 Euro 5 cars that run 20 km a day for a year.

The air purifying effect of 1m² artificial grass powered by PURETi is comparable with 1 mature tree towards NOX and VOC degradation. Consequently, a football field of 8,000 m2 powered by PURETi can be considered the equivalent of 8,000 mature trees, which corresponds to a forest of approximately 20 hectares.

PURETi reduces the NOx by 70%. 

PURETi reduces the NOX by 70%.

Anti-bacterial

PURETi prevents growth of mould, moss and algae.

On the pictures displayed, fungal pieces were placed on 2 samples of artificial grass, one of which powered by PURETi. PURETi almost completely degraded the mold after 6 weeks.

 

PURETi in other industries

Besides artificial grass, lots of other industries have been using PURETi because of the wide range of environmental, economic, and health benefits.
