KMB and LWB Become Hong Kong’s First Franchised Bus Companies to Adopt Nano-Photocatalyst Technology to Step up Compartment Cleaning

Passengers are particularly concerned about the health status of public areas during the coronavirus outbreak. KMB and LWB recently cooperated with a local technology company to adopt “Nano-Photocatalyst” spraying technology to medically disinfect the bus fleet, becoming Hong Kong ‘s first franchised bus companies to introduce the technology. Tests show that this disinfecting technology can kill and inhibit more than 99.9% of viruses, bacteria, formaldehyde and other volatile organic substances with a long-term effect. KMB and LWB have started to work on photocatalyst protection for their entire fleets, aiming to provide clean compartments for the public and their employees.

The “Nano-Photocatalyst” technology adopted by KMB and LWB has been internationally certified. After medical-level disinfection, seats, handrails, and other areas in the compartments will be coated with a disinfecting protective film. After absorbing light energy, this layer of nano-photocatalyst protective film will continuously release electrons and form reactive oxygen, instantly disinfecting, sterilising and decomposing pollutants on the surface of objects. Even in the absence of light, the nano-photocatalyst can still operate for up to eight hours, so that the disinfecting process will not be interrupted. 

The “Nano-Photocatalyst” can last for three months after spraying once. KMB and LWB will maintain daily cleaning of their bus compartments with disinfectants to protect the health of passengers and staff members.
