Few people eat an orange peel, but it is edible. We do eat the peels of other fruits, like peaches and apples. The peel is a kind of durable, biodegradable packaging. The fact that these fruits come in their own built-in packaging is convenient. It means they do not have to be sold in boxes or bags.
That idea is the inspiration behind a company that David Edwards has founded. He wants to change the way we package and eat food. His vision is that one day you will go to the supermarket and, instead of buying cartons of juice and cans of soup, you will fill your cart up with balls of food and drink.
