As a major transit city on the Mediterranean, Marseille’s urban history and landscape are largely defined by the continuous flows of matter and energy over time. Amongst these interwoven flows, the waste flow is one of the striking focal points. This is not only because the city of Marseille has historically struggled to escape its "dirty" reputation, but also because of its urban landscape today, which has been constantly reshaped by waste as a result of various natural and social events. In this project, the site of research is further targeted at the area near the estuary of the Huveaune River where waste and water flows densely intersect in the city. The idea of infrastructure as an intertwined system will facilitate alternative imaginations of Marseille's waste recycling facilities in order to re-project their social and ecological impact.
