Their solution is a large metal box which blasts shopping carts with ultraviolet light to kill germs.

“We have the equivalent of 2,000 suns in terms of UVC power received by the cart. So, the viruses have no chance of getting out,” says designer Jean Demarteau.

Exposure to UVC, a short-wave ultraviolet light, kills or inactivates microorganisms.

Three stores in Belgium are currently trying the machines.

“We asked the customers to disinfect the trolleys themselves and after a few months there was a lot of waste. We immediately took the offer to buy this machine. It’s simply practical,” says supermarket owner Henri Bormans.

The basic model of the cart cleaner costs just over $8,000.

Other countries are also trying to harness this cleaning power.
