The Strength of Light:

The problem of air pollution in large towns and cities is a major issue when it comes to safeguarding the environment and creating conditions of well-being for the population. Pollutants are created by human activities (vehicle traffic, heating, industrial production) and they build up in the lower part of the atmosphere in the absence of wind or rainfall. The measures taken by the Administrations in order to contend with this phenomenon have always been passive actions: fewer hours in which heating is permitted, restrictions to the use of vehicles. A decade of research first led to the creation of light activated substances, i.e. ones able to eliminate many of the pollutants, and then to a range of decorative products for façades capable of reducing pollutants harmful for man's health. Use of building materials is the simplest way for distributing light activated substances over vast areas with the utmost efficacy and a minimum extra cost.

Several organizations have been involved in trying to find solutions to limit contaminants in the air, unfortunately it is harder to get rid of pollutants than to simply slow down the contamination in urban, farm and industrial areas. The solution has come in the form of Eco-Active products that in an inexpensive form can contribute to the betterment of air quality indoors and outdoors, EcoVitali has been a pioneer in the development of this technology around the World, with innovative solutions that not only slow down pollution but effectively destroy the new contaminants created. From this perspective is essential to understand the importance of this approach and the great benefits to health and environmental challenges that are faced presently.

The possibilities are endless in the form of several products and practically infinite methods of applications in different settings and substrates, the contamination reduction capacity of our products comes accompanied with other active functions, for a list of the direct environmental, economic and health benefits.

Laboratory Tests:

Laboratory tests to assess the polluting characteristics of products with photocatalytic activity have been conducted with special equipment and equally pioneering test methods. The test to ascertain the efficacy of photocatalysis against nitrogen oxides (NOx) is conducted by using a chamber with a known volume into which NO2 is blown.

 This, diluted with the air in the chamber, reaches a previously established polluting concentration. The chamber contains an NO2 analyzer, a chemiluminescence analyzer, a UV lamp as light energy source and a sample of the tested product. Different tests at established light intensities are conducted and the concentrations of pollutant in the chamber are measured after the photocatalytic reaction accomplished by the sample.

 Up to 91% of the NO2 has been eliminated in certain laboratory conditions. When it comes to particulate matter, the efficiency of these photocatalytic products is evinced when these particles deposit on the surfaces of the products: the organic part is catalyzed, while the carbonaceous metal part remains unaltered. Further laboratory tests have also shown that photocatalytic products are efficacious against VOC.

 Pigmented organic compounds deposit on the surfaces exposed to the air. These compounds mainly consist of exhaust gas produced by the exhaust pipes of vehicles, pollutants from industrial and domestic activities, moulds, etc. These are the deposits that cause the exterior appearance of buildings to deteriorate. Photocatalysis acts by eliminating the organic molecules but indirectly, it also reduces the negative effect of the dirtying action caused by simple dust. This latter is able to cling to the surface of the buildings thanks to the organic molecules there. If these are no longer able to build up, the amount of dust is minimal and easy to remove. According to recent studies and the research into photochemistry applied to building materials conducted over the past few years, Vimark has developed the new Ecoaria Line in collaboration with Italcementi. This line comprises light activated products able to eliminate the organic and inorganic substances that are responsible for air pollution.

The new product range includes mineral finishes for protecting and decorating façades, facing mortar for fair-faced wall construction, products for protecting industrial floors and street furniture.

Additionally with more than a thousand studies performed by institutions, laboratories and Universities our technology is tested beyond any other has been in the last decade, this has come to represent one of the most reliable sources of environmental cleaning reliability to date.
