Food waste is one of the biggest environmental and economic challenges we face — and much of it happens long before the food reaches our plates. In this episode, we meet the people working to tackle the problem in different ways. We hear about the smart sensors which could help cut down waste by measuring when food has actually gone bad rather than relying on one-size-fits-all expiry dates. And in Scotland Myra visits the start-up turning waste from whisky production into fish food.
