For this project, the Franz Stock high school sent two young students pursuing the BTSA DATR (Development, Animation of Rural Territories) course on a 60-day outgoing professional mobility program. Higher Education Establishment is mobilizing to offer students a functional approach to economic organizations involved in the circular economy or social and solidarity economy, which is a "speciality" of the training offer. The vocational mobility project was therefore focused on Spain, in the Southern region of Andalusia to be more precise, where the young students were able to appreciate, in comparison with French realities, structures involved in new forms of collaborative economy (cultural offer managed by associations and re - use of so-called second-hand textile goods).
