2026 SUMMER SCHOOL IN TOLEDO. FIFTH DAY June 26th The summer school is coming to an end. In the morning, we have been following the D. Quixote steps at the Consuegra hills. Castle and windmill visit inspired us all with the spiritual values of the famous character. And to finish the visit to Alvinesa’s biorefinery in Daimiel. Thanks to Diego Simon for his interesting explanations on the factory activities and how the company has moved from the traditional alcohol production to the polyphenols and healthcare products.
