It is a young spin-off of ETH Zurich and aims at the global regeneration of coral reefs, the organization rrreefs based in Zurich.<\/p>\n
Founded in October 2020, the team has developed an artificial reef structure as a modular system made of 3D-printed bricks of pure clay and has already installed it at a pilot site in San Andr\u00e9s in Colombia. In the meantime, initial successes have been seen in the form of increased coral growth as well as a greater variety of fish.
\nIn terms of size and design, the reef structure can be individually adapted to local topographies and flow conditions of the seawater. The surface structure of the artificial reef stones supports the settlement as well as the survival of coral larvae and thus promotes the reproduction and growth of corals as well as their adaptation to new environmental conditions.<\/p>\n
In 2023, Marie Griesmar, Ulrike Pfreundt, Hanna Kuhfu\u00df and Josephine Graf plan to establish rrreefs as an environmental social enterprise.<\/p>\n
