In the town of Châtel-St-Denis, Switzerland, a start-up is leveraging artificial intelligence to make city cleaning more efficient worldwide.
It works by measuring urban litter in real time and spotting the areas that need urgent attention.
The idea, like many innovations, was born out of a problem. It was difficult for some Swiss cities to determine the number of street cleaning machines needed—the problem was that they couldn’t objectively determine how effectively they were tackling litter.
The solution was provided by start-up Cortexia, which has developed a pioneering system that maps out and measures the cleanliness of cities in real time.
