2026 Port of Aarhus – Femern Fyrtårn

Danish Technological Institute (partner), Femern Fyrtårn

As part of the innovation project "Femern Fyrtårn," Stonereefs, in collaboration with the Danish Technological Institute, has developed a new low-emission material for its reef modules. The material is based on moler clay and limestone and reduces the CO₂ footprint by up to 66 % compared with traditional materials. The first reef modules produced in the new material are installed in the Port of Aarhus, where they both function as marine habitats and demonstrate the potential for more climate-friendly solutions within maritime biodiversity infrastructure.
