Collect trash and provide a couch

Retrash is a sustainable project designed for the rest areas of the Primavera Sound Festival in Barcelona. The project has two functions: to collect waste from the festival attendees and to reuse this waste as the padding inside temporary seats. Bottles and plastic cups used during the festival are collected in Retrash’s PVC container, which, once full, is covered to provide a hexagon-shaped pillow.
