Frictionless trays aid hygiene at checkpoint

07 April 2017

Norway-based CQRTS reports that its anti-microbial frictionless trays for checkpoints are now retailing at half the price of standard security trays.

CQRTS owner Frode Storkaas had an airport security tray tested at a lab in Oslo. The results showed contamination from bacteria and viruses.

"Given this problem, it is important to ensure that trays are cleaned regularly, but this simply doesn't happen," Storkaas said. "Only a handful of airports have a regular cleaning routine. In fact, many trays are simply discarded when they become too dirty to remain in use, which means after a period of about three years."

As a solution, CQRTS developed a tray lined with a special plastic mixed with silver ions. When these are exposed to the natural humidity in the air, oxidation takes place that effectively stops bacteria and viruses from reproducing.

"During a 24-hour lab test, during which one of my trays was exposed to temperatures of 35°C for 24 hours, the killing rate for MRSI, which is a multiresistant bacteria, was 99.99%," said Storkaas.

The sanitary properties of the CQRTS tray are insufficient in themselves to attract customers, so the company had to build a financial case for airports. Storkaas claimed that his tray sell for about EUR30 (USD32), whereas the conventional trays favoured by the airport industry usually cost EUR60 each.
