Artificial grass that improves air quality
SPORTS & LEISURE GROUP NV announces an exclusive and worldwide partnership with NANOAIR SOLUTIONS - PURETi to improve air quality with its artificial grass.
PURETi, is a product that improves air quality by breaking down nitrogen oxides (NOX ), sulfur oxides (SOX) and volatile organic components (VOC). NOX and VOC are harmful substances mainly from traffic, industry and agriculture. NOX and VOC form an important part of particulate matter, which, 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.
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, 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, SPORTS & LEISURE GROUP NV is able to reduce NOX by 70%.
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.
This groundbreaking innovation improves air quality and reduces the health problems of both players and the environment. In addition to the air-purifying effect, the artificial grass treated with PURETi also destroys fungi, algae and mold, kills all bacteria such as E.Coli / Staphilococcus aureus and reduces bad odors.
PURETi has already proven itself in various industries such as public transport, construction, medical world (operating rooms & cleanrooms) and is a “Dual Use Technology Partner” of NASA, Google, Apple, HP and Tesla. From now on PURETi is also available worldwide exclusively in the artificial grass of SPORTS & LEISURE GROUP NV under the brands Domo® Sports Grass, FUNgrass and Namgrass.
How does PURETi work?
 |
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 turns nearby oxygen (O2) and water vapor (H2O) in into 2 powerful cleaning agents:
|
 |
 |
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 and CO2 |  |
 |
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. |
