Graya is a mobile app developed in Ivory Coast to fight food waste. It allows restaurants and supermarkets to offer their unsold products at reduced prices to consumers. Users can geolocalize close offers, receive notifications for new unsold products, and view detailed descriptions of available products. In addition to allowing institutions to track their waste reduction statistics, the application also encourages donations to charitable organizations. Graya’s economic model is based on a commission per transaction and advertising options, thus helping to reduce the economic losses of businesses while restoring purchasing power to consumers.
