Project Description

Our plan is a novel project that returns plastic waste—once considered a mere nuisance—back to nature through the medium of "artificial reefs." While traditional artificial reef projects using concrete and steel were undoubtedly initiated to support marine ecosystems, they contain paradoxical flaws: high carbon emissions during manufacturing, toxic heavy metal leaching from corrosion, and high pH alkalinity that adversely affects marine life. This project marks a new turning point for artificial reefs through a shift in materiality. Lightweight and highly processable plastic will drastically reduce carbon emissions during manufacturing and transportation. The most significant difference lies in utilizing waste that must be disposed of, rather than consuming precious resources like concrete and steel.

At this point, a critical question may arise: "Is this plastic artificial reef just adding another massive piece of trash to the ocean?" In reality, if a plastic structure were simply placed in the sea as-is, while not immediately toxic, it would eventually generate a new problem: microplastics. Symbolically and functionally, this structure represents the return of plastic to nature. It functions as an underwater landmark that can revitalize local communities through eco-tourism and spark broader environmental awareness. The high processability of 3D printing enables adaptive geometries. Our primary design is inspired by the organic shape of a conch shell. Strategically placed perforations allow the structure to 'breathe' with the ocean, providing diverse micro-currents, shelters, and spawning grounds for marine species.

Experientially, as time passes, the structure is gradually engulfed by coral. Ultimately, every surface becomes colonized, allowing what began as human-made waste to seamlessly transition into a living part of nature. The solution lies in a dual-layered natural coating that encapsulates the structure. A near-nontoxic graphite paint layer completely blocks the release of microplastics. Furthermore, applying a micro-current through this graphite paint generates a natural limestone layer. This electro-deposited limestone shares similar properties with natural coral, drastically increasing the survival and settlement rates of coral polyps (baby corals).

Ultimately, this project is perfectly suited for a volume of 10 cubic meters. This specific scale is highly optimized for fabrication using large-scale 3D printers. Additionally, it is the ideal dimension for the entire project lifecycle, ensuring maximum efficiency in transportation, installation, and modularization.
