This proposal for a Material Recovery Facility forms a stitch between the Long Walls strip and the City of Piraeus. Working into the existing transportation infrastructure surrounding the site, this project provides Athens with necessary waste infrastructure while incorporating space for public use and improved pedestrian accessibility. The public and operational elements of the program coexist, reimagining the city’s relationship with its infrastructure. In addition to the Material Recovery Facility, which processes building materials from demolished structures, this proposal includes rentable workshop spaces for local craftsmen, a marketplace, and a pedestrian bridge. Making use of the existing sectional change of the site, materials are input at the highest point of elevation and are processed along the site’s natural slope. Once materials reach the highway and train infrastructure, they are either sent out for distribution or remain on-site to be repurposed in the workshops and sold in the marketplace.
