In Catalonia alone, every day, 720,000 kg of food is thrown away. This wasted food, totaling 260,000 tons per year, is equivalent to the food needs of 500,000 people for one year. Remix el Barrio was born with the ambition to propose a learning space to encourage and nurture new practices based on food-waste crafts. It is the result of a pilot program where various designers learn about biomaterial design and explore projects with food scraps using artisanal techniques and digital fabrication. Remix El Barrio was created in the regenerative district of Poblenou, more specifically in the ecosystem of Fab Lab Barcelona, where designers united to co-produce new forms of crafts from their individual aspirations, benefitting from regular peer-learning sessions, access to machines and tools, and learning from the maker open source culture present all over the place. Each designer has initiated a creative design driven material innovation approach where they identify a recurrent local food waste case, learn about its characteristics, investigate how to best collect and process it, and imagine future applications and material life-cycle narratives.
