Our Mission

Our mission is to rebuild coral reefs to sustain a healthy ocean for life below water and to bring back abundant marine biodiversity. Our well-designed reef made of 3-D printed clay reefs create a solution to regenerate damaged reef, restoring reef ecosystem services such as biodiversity,




Coral reefs protect coastlines from storms and erosion, provide jobs for local communities, and offer opportunities for recreation. They are also are a source of food and new medicines. Over half a billion people depend on reefs for food, income, and protection. Yet, a warming planet means a warming ocean, and a change in water temperature—as little as 2 degrees Fahrenheit—can cause coral to drive out algae. Coral may bleach for other reasons, like extremely low tides, pollution, or too much sunlight. Only 20% of global tropical reefs are in good condition with roughly half having collapsed in recent years.

How rrreefs can scale global reef regeneration with your support

rrreefs is a Swiss-based Not-For-Profit organization pioneering a scalable solution for ecosystem regeneration, through the use of modular 3D printed clay structures to support and enhance coastal ocean life. Ocean acidification, pollution, and overfishing are ever-present threats to ocean life and rrreefs believes that these challenges can be overcome in part by simply creating more spaces rebuilding lost habitats to support the ocean’s existing biodiversity.

Their innovative hollow lego-like brick lattice provides a profound number of niches for ocean life, in a way augmenting the natural role of coral reefs on the ocean floor. Each brick has a finely textured eco-engineered surface, offering a home to hundreds of organisms each.

As a completely modular system, their synthetic reef supports be constructed to complement natural tides and topography, providing erosion protection and a wide variety of niches. The bricks are 3D printed in clay and heat treated, providing an ideal substrate for corals to attach to and grow. Better yet, this design can be produced locally using open-source plans, creating new jobs globally in ecosystem restoration.

Ultimately this biodiversity gives a food source and growing medium for new corals to take root, turning a man-made structure into a vibrant and diverse biological community.
