GUSTOS is an European project that promotes the prevention and reduction of food waste in school canteens in the Basque Country and Catalonia. We work to involve the entire educational community in building a more conscious, fair, and sustainable food model.
Through educational and gastronomic interventions, GUSTOS encourages reflection, action, and the measurement of food waste in each school.

Who we are
The project, coordinated by Ausolan and developed in collaboration with Elika, Espigoladors, GOe Tech and DARPA, combines technical knowledge, social innovation, and gastronomic expertise to achieve a common goal: to reduce food waste by 15% before 2027.
Beyond the numbers, we seek to create shared learning experiences and transform school canteens into true spaces for change that inspire a more sustainable future.

In GUSTOS, we design five interventions that combine educational and gastronomic strategies to address food waste from an integrated perspective, considering the school canteen as a living space for experimentation, critical awareness, and collective learning.
What types of interventions do we foster?
EDUCATIONAL INTERVENTIONS
We will implement three educational and training interventions in 10 schools in the Basque Country and Catalonia, with the objective of reducing food waste by at least 15% and fostering a shift in awareness toward more sustainable eating habits within the educational ecosystem.
Intervention 1: Training for school canteen staff.
Practical training addressed to the monitoring team so they can actively contribute to preventing and reducing food waste in the canteen, while promoting more sustainable habits together with the students.
Intervention 2: Educational games during the midday break.
Design and implementation of pedagogical games during the lunch break, with the goal of raising students’ awareness about food waste through playful and engaging activities that encourage critical observation and active students involvement in reducing food waste.
Intervention 3: Transformative pedagogical methodologies.
Application of the Service-Learning methodology so that students can research, think over and act regarding food waste, encouraging concrete initiatives that generate a positive impact in their immediate environment and integrating learning through action and community engagement.

GASTRONOMIC INTERVENTIONS
In GUSTOS, we use gastronomy as a driver of change to reduce food waste by at least 15% in 10 Basque Country and Catalonia school canteens. The interventions combine culinary creativity, education and participation to tailor the menus to the real tastes and needs of the students, and significantly reduce food waste in the canteen.
Intervention 1.
Using participatory methodologies, we co-create delicious, healthy and sustainable menus together with students and canteen staff.
Intervention 2.
In addition, we focus on the co-design of utensils that allow better portion control, avoiding excess and promoting more mindful consumption.
Small decisions in the kitchen trigger big changes for the planet!
PARTICIPATING SCHOOLS
Participating schools play a key role in the GUSTOS project. Thanks to their commitment, school canteens become vibrant spaces for learning, experimentation, and change, where students, canteen staff, and the wider school community work together to prevent and reduce food waste. The active involvement of each school allows for the implementation, measurement, and improvement of the project’s educational and gastronomic interventions, generating real-world learning and results that can be transferred to other educational contexts.
