Many tech startups have introduced new solutions to food waste at the Consumer Electronics Show (CES) 2023 in Las Vegas. According to the United Nations, about one-third of food is wasted globally. The goal of the startups is to reduce the amount of food that’s being thrown away and to offer quick ways to compost food trash.

One of the startups in CES 2023 is OneThird by Dutch entrepreneur Marco Snikkers. Snikkers created an avocado scanner. The scanner, which is designed for supermarkets, was made to reduce the number of overripe avocados that people throw away. Currently, Snikkers is also working with growers of tomatoes, strawberries, and blueberries so that the scanner can be used for other produce.

Another device introduced at CES 2023 is the Orbisk food camera. It was created by entrepreneur Olaf van der Veen to scan food that’s going to be thrown away. According to van der Veen, there’s more food waste in restaurants in the U.S. than in Europe even after some surplus food is donated. The Orbisk can help restaurants understand their food disposal patterns. This may help them save money and reduce food waste.
