The marine renaturalisation project in Alcudiamar is delivering excellent results ten months after its launch.

After ten months in operation, the Alcudiamar renaturalisation project is significantly increasing biodiversity, marine biomass and CO₂ fixation capacity. This is backed up by the initial scientific results of the project, developed in collaboration with the Spanish technology company Ocean Ecostructures.

In April 2025, ten biomimetic micro-reefs (Life Boosting Units®) (LBUs) were installed. Among the results obtained in this first monitoring, there has been a 56% increase in the number of species in the port thanks to the implementation of this technology. In total, 38 native species have been recorded, including five species of juvenile and mature fish of commercial interest, which have found their habitat in the renaturalisation units. The greater richness of functional groups on these structures indicates the presence of a healthy and balanced community.

The biomass generated by the LBUs reached 82 kg, representing a 20% increase in attached marine life compared to other areas of the port where no intervention has taken place. In terms of CO₂ fixation—a parameter that indicates the amount of carbon dioxide equivalent captured by the organisms colonising the micro-reefs—the LBUs accumulated 35 kg, representing an increase of 19%.

The results confirm that these structures are helping to transform the port environment into a more complex, diverse and healthy habitat, promoting the presence of fauna, increased biomass and higher environmental quality. This progress consolidates Alcudiamar as a benchmark in the development of nature-based improvements for port infrastructure.

The project is being developed in collaboration with Ocean Ecostructures, a technology company specialising in solutions for the large-scale renaturalisation of marine biodiversity. Its Life Boosting Units® (LBUs) biomimetic micro-reefs incorporate the unique and pioneering Bio Boosting System® technology, which allows complex and resilient ecosystems to be created in a very short time.
