A new coating technology can be applied to food processing plant interiors to inhibit odors and reduce bacterial contamination, according to its developer, Canadian-based Green Earth Nano Science.

The technology uses titanium dioxide (TiO2). Once a surface is coated with TiO2, it remains self-sanitizing as long as enough light is present to trigger its photo catalytic effect. This destroys a bacteria cell’s wall and membrane, and reacts with the cell’s components, inhibiting the bacteria’s activity.

Since the coating does not use chemicals or wastewater, it reduces both environmental footprint and operational costs.
