Polymeropolis, a floating city made of waste

As the temperatures of the Earth continue to rise, melting the polar caps and rapidly increasing the level of the tue, many countries have already started to urbanize the sea to avoid going underwater.

Following in the footsteps of the Buzan project from South Korea and Oxagon from Saudi Arabia, Estudio Focaccia Prieto proposes Polimeropolis, a giant group of floating cities that enclose lagoons of uncontaminated seawater to offer a new ecosystem sustainable housing.

Creating a metropolis in the depths of the Great Pacific Ocean, The project plans to clean up the heavily polluted mainland with a self-contained sustainable city built from self-capturing recycled plastic.

Polimeropolis also generates clean electricity and water on site with renewable systems. Principal architects Juan Manuel Prieto and Clara Focaccia present their visualizations through a series of Midjourney-generated drone shots done in collaboration with artist AI Maxi Araya.



Presented as a stepwise, scalable model of a city, the conceptual project comprises a sequence of mixed-use urban 'rings', each hosting a cluster of habitats while enclosing a massive ocean lagoon.

Surrounding the islands, the Estudio Focaccia Prieto team creates a waste collection boundary made of nets and vegetation associated with phytoremediation, which restrict the passage of microplastics and purify the water. This achieves a sanitized environment where marine and human life can flourish.

A giant floating island that cleans up the ocean and prevents humans from drowning in their own trash, Polimeropolis will be built primarily from recycled plastic waste found in the water.

The waste will be crushed and compacted on site in floating factories dedicated to producing the components of a fully recycled construction system. 

In addition, totally self-sufficient, the floating cities will generate their own resources and the movement of the tides will generate electrical energy while reverse osmosis will create drinking water. Food production will also be based on the cultivation of marine flora and fauna in the closed lagoons.
