Netherlands-based startup SeaCrete has raised €100,000 in pre-seed funding for ocean concrete substitute that can be used for oyster recovery, as well as potential coral outplanting, sea grass relocation and urchin restoration. The company will use the funding to scale up its innovation, moving closer to practical applications in reef restoration and marine infrastructure.
SeaCrete, a spin-off from Wageningen University & Research, creates a substance that binds together oyster cultch, coral rubble or any other desired material. It is a paste-like material that can be molded into different shapes for specific applications and can last for months or years on the sea floor. It is designed to replace concrete which is often used for things like reef restoration but which has a high CO2 footprint and seems like putting non-natural substances in the ocean.
“We are developing a bio-based coating for concrete that helps increase biodiversity in marine environments,” said CEO Marc van der Peet. “That’s a pressing issue globally. Coral reefs are fading, and oyster populations are declining, both of which play a crucial role in healthy ocean ecosystems. Our material supports the rebuilding of oyster reefs and coral reefs. Until now, this was just a promising lab technology. With this funding, we can finally take the next step.”
The funding came from StartLife, an impact investment firm for the agrifood industry.
