Erriberitu is a space for the exchange of objects such as clothes, books and small electrical appliances designed and built by the students of the Global Digital Humanities course of Mondragon University during the 2022-2023 academic year. The students worked on the development of a temporary urban planning proposal focused on promoting the circular economy and sustainability at neighbourhood level. The students worked in 4 teams: Food, Exchange, Manufacturing and Education, each of them focused on developing an aspect linked to the circular economy. The group dedicated to the exchange built structures designed to store objects such as clothes, books, toys, and materials. The food team constructed a large mobile barbecue, intended for use by the neighbourhood in parties, gatherings, and activities, which has been donated to the neighbourhood association. The students from the manufacturing team created a map of the companies currently operating on the island, with the aim of fostering connections among them and promoting resource exchange. Meanwhile, the education team prepared informative panels with content aimed at spreading the principles of the circular economy. The result is a collection point open to anyone who wants to leave or take things, under the slogan "leave what you want, take what you need".

The project allowed the mobilisation of neighbourhood associations and local companies towards a collective goal. The possibility to collect items for free made the initiative financially inclusive and promoted reuse over mindless consumption. Such experiential learning paths can empower young people to be active agents of change at a local, tangible scale, providing them with the confidence and knowledge to implement projects beyond universities’ labs.
