Food waste is a massive problem. These sensors offer a solution


Food waste has become a critical global issue. Almost 10% of the 8 billion people on Earth are undernourished, but nearly a third of the food on our planet is trashed before it’s eaten.

A startup called Positive Carbon has proposed a solution. The Irish company has developed a sensor-based system that tracks, traces, and reduces food waste.

According to the startup, the tech has triggered 50% reductions in waste — saving over 4,000 tonnes of food. Designed for commercial kitchens, the tech can cut costs as well as litter.

Mark Kirwan, Positive Carbon’s CEO, told TNW that hotels, hospitals, workplaces, and university campuses could all reap the benefits.

 “Our technology is not just a tool for reducing food waste; it’s the driving force behind fostering a sustainable ecosystem that benefits businesses, the environment, and society at large,” he said.
