This article contributes to the issue of technological innovation to reduce food waste. It focuses on the case study of Too Good to Go among university students in Portugal. In this regard, the study aims to contribute to the current research on sustainable consumption patterns through technological innovation, highlighting ideas to promote the reduction of food waste through specific actions. With this aspiration in mind, this study analyses the Too Good To Go case study. It also uses a mixed-methods approach, using a survey to assess the target audience’s knowledge, use, and perception of the app, as well as their attitudes towards food waste and sustainable consumption. The aim is to explore how the app can be used to promote sustainable consumption through the circular economy and artificial intelligence. With 160 responses received, the results conclude that the strategies analyzed have the potential to reduce food waste and can play a significant role in promoting a more sustainable and circular food system, thereby engaging students and encouraging sustainable consumption behaviors.
