Imagine a platform that could bridge the gap between those with excess food and those in need of it. efridge aims to be that solution. These communal fridges, located in grocery stores, would allow individuals and retailers to deposit their spare ingredients. Customers could use the app to locate the nearest shared fridge containing the ingredients they require. They could also “open the fridge” and search the items they need in efridge. Users can gain points with any kinds of activity (providing or consuming items). Points can be used for cash back to improve users loyalty. Equivalently, users can exchange a free meal for homeless people with significantly less points to boost social sustainability.
