People throw away a large amount food everyday because it goes bad or they just have no use for it. Sometimes you're only one ingredient away from being able to make something from what you have in your pantry, but that's not enough to drive all the way to the grocery store for. Asking your neighbor for a cup of sugar is old school, why not trade/purchase any item from each other's pantries? That's the idea behind Pantry. People would go onto this app and list their desired items as well as the items they have excess of in their pantry, and they would then contact each other and set up a trade.
