Introducing the Marble Green Wall, which not only tackles issues of waste but also reclaims the true values of green walls in the first place: their air purification and their unanticipated beauty. Our concept repurposes discarded quarried marble slabs, or "remnants," as we seek out the unique substrates within distinct slabs to create a unifying wall-canvas. A more hands-on, less industrialized approach to designing green walls could push these ever-more frequent installations to their fuller potential, maximizing their grandeur and impact with carefully selected, untapped materials.
