waste management
The Copia app is one of the coolest apps to ever come out. The purpose of this app is to connect those with surplus food, food that is going to get tossed with people who have food needs. The idea for this app came from Komal Ahmad. Anyone can download the app, take a picture of your food to unload, and send the picture in. 
The app will connect with a pickup team who will come get the food and take it to distribution people, who connect with those in need.
This app is a great leap in hunger relief.
