By replacing a significant portion of the cement in the concrete mix, the Port is lowering the carbon footprint of the project and establishing a new circular pathway to build future Port infrastructure.

The first Coastalock units are installed, with hundreds to follow suit in the coming months. The biodiversity and ecosystem uplift will be tracked through a rigorous monitor program including AI-powered underwater cameras provided by Copenhagen based Anemo Robotics.

This project is a great example how innovative material design, engineering, and ecology can come together to deliver scalable, nature-inclusive marine infrastructure. Delivering multiple benefits from circularity and CO₂ reduction to coastal protection and biodiversity enhancement.
