At the heart of Rome, Mōns No.9 transforms Nuovo Mercato Esquilino into a layered system of closed-loop infrastructure and artificial nature. Rising above the market, an artificial mountain made of recycled plastic and curated waste turns disposal into architecture. Beneath its sculpted form, machines sort, shred, and melt plastic into panels and structure, while organic waste is composted, rainwater harvested, and rooftop gardens grow.

Inspired by Rome’s ruins and topography, Mōns No.9 treats waste as cultural curation — a monument to the Anthropocene that records our habits of consumption. This is not just a building with a waste system — it is the waste system: a living, self-sustaining terrain where nature is fabricated from waste and disposal becomes a public ritual of material memory.
