The dangers of pollution

Among the hours we spend at home, in the office, school, gym or shopping center, it is estimated that 90% of our city life takes place indoors. This is why indoor air quality has a fundamental importance for our health. In many areas of Europe, life expectancy is one year reduced due to air pollution and 90% of the population living in urban areas is exposed to unsafe levels of pollutants. Not seeing the smog does not mean being safe from it, if adequate countermeasures are not taken. The air in confined spaces, on average, is 5 to 10 times more unhealthy than outside due to the accumulation of pollutants.

 

domestic pollution

Pollution of domestic environments derives from products that we all have at home or in the office, both and coming from external agents. These products cause additional pollutants: fine dust, molds, mites, bacteria, carbon monoxide, nitrogen dioxide and a large family of molecules: “volatile organic compounds”. This category of compounds (VOCs) includes a series of substances, all containing carbon in complex mixtures, which easily evaporate already at room temperature. More than 300 are known, the best known are aliphatic hydrocarbons, terpenes, aromatic hydrocarbons, chlorinated hydrocarbons, alcohols, esters, ketones and aldehydes. In some cases their concentration in indoor environments may exceed that of outdoor. This class of compounds can cause short and long term damage to human health.

photocatalysis with visible light

photocatalysis with visible light

our solution to the problem of indoor pollution

Our technology uses doped titanium dioxide (TiO2) which is activated by the visible light generated by a special LED card calibrated on an adequate wavelength with visible light that gives the start of a process called oxidative photocatalysis. The patented substance applied on the filters, or upon various supports such as panel’s luminous screen, is photo-active, ie it is “activated” by LED visible light with calibrated spectrum, generating free radicals (molecules that instead of being neutral are charged and much reactive), which attack the polluting molecules (as well as viruses or bacteria) that pass by suction into the GearBox filter or which passes on the screen, breaking their chemical bonds and degrading them. For this reason, the pollutants don’t accumulate on the ceramic filters but they are transformed into non-harmful substances. The skilful mix between visible LED light and the high reactivity of doped TiO2, the result of years of research and experimentation, allows us to assert that WIVActive technology allows our lighting products to be safe for humans, animals and the environment as they do not release any harmful substances at the end of the sanitation process.

WIVActive patent

WIVActive patent

nanomaterial exclusive patent

Studies and research carried out by WIVA Group, in partnership with CE.RI.COL., have led to the development of a unique nanomaterial. The result is a TiO2 doped with nitrogen and silver nanoparticles together with particular chemical elements. This particular and unique mixture has allowed us to eliminate the use of UV rays to perform a photocatalysis process. The doped silver nanoparticles and TiO2 react with the water molecules present in the air, releasing free radicals, but also silver ions capable of oxidizing most of the organic VOC contaminants, breaking down nitrogen oxides (NOx), carbon monoxide and also to control and reduce the bacterial load due to fungi and bacteria. All without the creating of Ozone and UV.

exclusive patent on the production process

Having the possibility of making a nanoparticle-based coating process reproducible and therefore stable is a very demanding job. The coating and surface softening by means of an oven allows a secure fixing of the nanocomposite to the support.

exclusive patent for photocatalytic functionality

The WIVActive system uses a revolutionary optical scheme to obtain greater homogeneity and very low pressure drop, which is essential for filtration systems.

WIVActive plant

an european excellence

Wiva Group has designed and built under the scientific supervision of CE.RI.COL a production plant dedicated to sanitizing products. The plant represents an absolute European excellence in the treatment of nanocomposed materials. For the design of a production line with the characteristics necessary to meet the technological requirements suitable for treatment of nanocomposites, it took years of research and experimentation. The processes related to the treatment of elements, such as ceramic filters that are on board the GearBox as well as the coating of surfaces and materials inherent to sanitizing products, provides a certified industrial principle. All stages of this delicate process take place in our factory and this allows total control of all functions both technological and industrial.

“This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 862444”

The treatment plant with WIVActive technology is designed, according to the methods of Safe-by-Design (SBD), through the European project ASINA “Anticipating Safety Issues at the Design Stage of NAno Product Development”. The project is coordinated by the ISTEC Department of the CNR and is made up of 21 partners including Research Centers, Universities, European and non-European NGOs and companies, including Wiva Group.

the coating

The nanomaterials are applied to the surfaces through a specifically developed coating treatment. The mixing and fixing of the nanocompound is a process that requires absolute knowledge of the chemical dosages and temperatures suitable for softening the fine surfaces to let the nanotitanium to penetrate at a molecular level on the support to be treated. The particular chemical composition of this substance, based on a special patented formula of titanium dioxide doping with silver and other elements, ensures that it is activated simply thanks to the action of artificial visible light, even in the absence of UV rays.

certifications

The antiviral certification obtained by WIVActive technology is based on the analysis of the Bovine coronavirus virus (SsCoV-1). Bovine coronavirus represents the surrogate virus of all Betacoronaviruses (as per documentation released by the World Health Organization) which includes viruses such as OC43, HKU1, SARS-CoV and SARS-CoV-2 (COVID-19). This certification attests to the antiviral capacity of the WIVActive system to act on the digestion and reduction of the Betacoronavirus thanks to free radicals generated by the photocatalytic system activated with visible light with a calibrated spectrum.

The antibacterial certification obtained by WIVActive technology is based on the analysis of the bacterium Escherichia Coli, a microorganism belonging to enterobacteria (Enterobacteriaceae family), so called because they find their habitat ideal in the intestines of humans and various other animals. This bacterium was used by the Eurofins laboratory because it results be one of the most resistant and dimensionally important to verify the effective antibacterial action of the system WIVActive.

 

The substances capable of altering the quality of the indoor air can be classified as: chemical, physical and organic agents; they come in part from the outside (outdoor air pollution, pollen), but many are produced from the internal sources. The main internal sources of pollution are represented by occupants of the rooms, dust (receptacle for microorganisms), structures, building materials, furnishings and air conditioning systems. The chemical risk is mainly linked to the presence in the indoor air of the following chemical pollutants such as oxides of nitrogen, airborne particulate matter, volatile organic compounds and formaldehyde. The certifications obtained by the WIVActive system demonstrate the effectiveness of our technology and products.

Indoor pollutants

Le sostanze in grado di alterare la qualità dell’aria indoor possono essere classificate come: agenti chimici, fisici e biologici; provengono in parte dall’esterno (inquinamento atmosferico outdoor, pollini), ma molti sono prodotti da fonti interne. Le principali fonti interne di inquinamento sono rappresentate da occupanti degli ambienti, polveri (ricettacolo per i microrganismi), strutture, materiali edili, arredi ed impianti di condizionamento. Il rischio chimico è legato soprattutto alla presenza nell’aria indoor dei seguenti inquinanti chimici come ossidi di azoto, particolato aerodisperso, composti organici volatili e formaldeide. Le certificazioni ottenute dal sistema WIVActive comprovano l’efficacia della nostra tecnologia e dei nostri prodotti.
