GreenGuard is a long-lasting photocatalytic coating powered by doped titanium dioxide for large, high-traffic spaces or livestock facilities. Activated by UVA light, it continuously destroys viruses, bacteria, mold, spores, and VOCs from air and surfaces — creating safer spaces without toxic chemicals. 

While GreenPure is a directly applied powder, GreenGuard refers more to an installed service/technology: e.g. photocatalytic coatings applied on walls/ceilings and special UV lamps that, when switched on, activate these coatings. The aim is to continuously eliminate viruses, bacteria and fungi from the premises and the air, achieving environments with a higher level of hygiene without the need for chemical sprays.

Where is GreenGuard used? It was conceived for airports, airplanes, hospitals and public spaces, but it also has applications in farms, hatcheries, milking parlors, veterinary laboratories or anywhere where airborne biosecurity is crucial. For example, in a chicken house, GreenGuard complements GreenPure by attacking airborne pathogens that can cause respiratory disease.

How does it work? GreenGuard takes advantage of photocatalytic technology: surfaces coated with a nano-material (TiO₂ doped with silver and nitrogen, for example) that under UV-A light produces radicals that oxidize and destroy microorganisms. It is installed in a fixed manner: UV light equipment in strategic areas (ceiling, ducts) and/or coated panels on the walls/passages. Once in operation, nothing special is visible - the light may be invisible UV - but in the environment viruses and bacteria are neutralized on contact with the active surfaces. The system is designed to operate 24/7 safely: the UV-A light used does not produce ozone or harm people/animals present.

Key benefits: What does GreenGuard bring to a customer?

• Continuous and autonomous disinfection: Unlike traditional disinfectants (which act only at the moment of application), GreenGuard protects constantly while the UV lamps are on. This means that even between cleaning days, the air and surfaces are being sanitized. For example, in an airport, contagions are reduced in waiting rooms; on a farm, the microbial load is lowered between batches without daily manual intervention.

• Proven efficacy against pathogens: Advanced photocatalysis removes viruses (including coronavirus, influenza), bacteria (Salmonella, E. coli, Listeria) and fungal spores in the air with high efficiency (>90% reductions in airborne microbial load are typically achieved in the first few hours). This improves biosecurity: less risk of airborne disease outbreaks. Pilot studies on farms with similar systems showed 10% improvement in conversion and less respiratory disease in animals exposed to decontaminated air.

• Low maintenance and operating cost: GreenGuard has a relatively simple installation (lamps and initial photocatalytic coating application). It then only requires changing UV lamps every few hours of use (e.g., annually) and occasional dusting of the panels. It does not consume chemicals or generate waste; the electrical consumption of the lamps is low. This makes it sustainable and economical in the long term compared to routinely fumigating or filtering the air with expensive HEPA systems.

Applicable in critical environments: Ideal for places where you can't be constantly spraying disinfectant. Think of a veterinary hospital: GreenGuard keeps the environment sterile without wetting equipment or disturbing animals. Or a poultry hatchery: it helps prevent the spread of pathogens between eggs, with no residue to affect the chicks. Even in the offices of agricultural companies, a GreenGuard module improves air quality for employees (added value in post-pandemic times).
