Green Earth
Nano Science, Inc., Canadian environmental and nanotechnology solutions
developer recently received approval from Canadian Food Inspection Agency (CIFA)
for its GENS NANO - self-sanitizing photocatalyst coating.
GENS NANO - photocatalyst coating is part of a revolutionary 3-Dimensional
Air and Surface Purification System that utilizes natural mineral titanium dioxide
(TiO2) for surface purification in combination with HVAC air purification systems
utilizing UV-C ultraviolet light. Both, titanium dioxide and UV-C purification
technologies are environment friendly and a unique solution to growing problem
of surface and air bio-contamination risks faced by food processing facilities,
food transportation, poultry farming and public buildings.
Titanium dioxide itself has no toxicity to microbe and the cell. Only after
the irradiation of light such as fluorescent or UV light, natural mineral TiO2
activates its unique photo catalytic properties. In the presence of light and
humid in the air, titanium dioxide oxidizes, converts complex organic molecules
into water and carbon dioxide. Photo catalytic power of titanium dioxide successfully
destroys bacteria cell’s wall and its membrane, and reacts with cell’s
components, which inhibits bacteria’s activity and ultimately results
in the death and decomposition of bacteria, thus eliminating bad odours created
by a living or decomposing bacteria and also reduces risk of bacteria spread.
GENS NANO 3-D Air & Surface Purification System not only improves indoor
air quality but also effectively reduces organic based compounds (ammonia &
ethylene gases, VOC’s), organic based odours, bacteria (e.coli, listeria,
bird flu, mould). In practise, cleaning and disinfection of interior surfaces
such as ceilings and walls causes considerable trouble, high consumption of
chemical detergents and water, intensive labour and consequently high costs.
Any disinfection done today protects surfaces only for few minutes or few hours.
Installation of advanced self-sanitizing coating protects building’s interior
such as walls, ceilings and other treated areas for years depending on surface
type and treated areas. Once coated, surface remains self-sanitizing provided
that enough light is present to activate photo catalytic effect of titanium
dioxide. Various tests proved that treated surfaces, when illuminated by light,
efficiently control and restrain bacteria growth reducing risk of surface bio-contamination
and legal liabilities from potential bacteria outbreaks. Canadian technology
brings additional benefits for the environment and the facility such as: less
water and chemicals needed to disinfect walls and ceilings, less impact on the
environment, improved indoor air quality and reduced building maintenance costs.
There is never too little bio protection when it comes to schools, offices,
hospitals and food facilities. Installation of self-sanitizing natural mineral
coating on walls and ceilings together with UV-C air purification system inside
those facilities will help to reduce to a minimum any potential risk of bio-contamination
and even could prove to be utilized for defence in bio terrorism.
