(CNN) - An online startup wants to make a refrigerator full of leftover food a thing of the past.
The website and smartphone app "Leftover Swap" will be a place for you to sell, say, an uneaten half of pizza.
The company says it wants to prevent food waste, while promoting eating local and building communities.
