These ‘Reef Cubes’ Are a Plastic-free Alternative to Artificial Reefs and a Dream Home for Lobsters, Crabs, and Fish

These ‘Reef Cubes’ Are a Plastic-free Alternative to Artificial Reefs and a Dream Home for Lobsters, Crabs, and Fish

Artificial reefs are crucial in protecting offshore wind farms from powerful tides, yet the ones being used often contain plastic, which can be detrimental to marine life. To remedy this, a start-up named ARC Marine has developed a biodiversity-boosting, a plastic-free alternative called reef cubes.

These genius reef cubes are made from recycled aggregate and sand. According to the company, this reduces carbon emissions by 90% compared to the processes used to make common types of cement. The interlocking of the reef cubes creates more real estate for lobsters, crabs, and fish. Plus, they have a porous surface, which boosts the growth of marine plants. So, it’s a win-win.



The ultimate goal of the implementation of these alternative reefs is “to protect vital offshore installations from storms and erosion while also encouraging marine biodiversity.” Essentially, these reef cubes are “building blocks for the ocean” says Tom Birbeck, CEO, and founder of ARC Marine.
