The Balearic Islands Port Authority (APB) takes a decisive step to protect the species that inhabit the port of Mahón

The Balearic Islands Port Authority (APB) is taking a decisive step to protect the species that inhabit the port of Mahón with the tender for the mapping of the distribution of habitats and sensitive species of its seabed. The project, funded with an investment of more than 330,000 euros, will provide an essential scientific tool for planning the future of the port while respecting the environment.

The port of Mahón, one of the largest natural ports in the Mediterranean, has unique environmental features that make it a space of great ecological value. With this study, the APB will be able to know precisely which species live in its waters, where they are located and in what conditions they are found, ensuring that any future action takes into account the protection and conservation of this unique environment.

The resulting maps will serve as a basis for decision-making, planning of new actions and long-term environmental monitoring, reinforcing responsible, sustainable port management aligned with current environmental regulations.

Furthermore, the project goes beyond mapping, as it includes the organisation of open 0technical and educational workshops to disseminate the results. The aim is to bring the knowledge that is created closer to citizens and professionals and to ensure that the actions and infrastructure work in the port of Mahón are carried out with greater information, care and respect for the marine environment.

This initiative has its origin in previous experiences in the port, when it was necessary to halt works in the cove of Cala Corb when the presence of a species of coral endemic to the area was detected. This finding highlighted the importance of forward planning and having detailed and rigorous information that allows port activity to be compatible with the preservation of the marine environment.

The deadline for submitting applications to participate in the tender will remain open until March 2. With this project, the Balearic Islands Port Authority reaffirms its commitment to the protection of marine biodiversity and to a port development model that takes care of the environment that makes it possible.

Industrial circularity and energy symbiosis: the Rotterdam Port model

Rotterdam Port has established itself as a model in Europe in sustainability and advanced resource management, transforming its traditional role as a logistics hub into a circular industrial ecosystem. This model, based on energy and industrial symbiosis, demonstrates how collaboration between companies, authorities and energy actors can transform the waste of one activity into the raw material of another, driving a new blue economy paradigm applied to the port environment.

At the heart of this strategy is the Porthos project, which promotes the creation of the first European hydrogen and carbon capture (CCS) corridor. Through this shared infrastructure, the port manages the transport and storage of CO2, offering companies a new service model called “Carbon as a Service” (CaaS). This collective solution reduces individual implementation costs and speeds up the decarbonisation of the entire port community.

Rotterdam also leads pilot projects for chemical recycling and the production of sustainable aviation fuels (SAFs). Through advanced pyrolysis processes, marine plastic waste and non-recyclable industrial flows are converted into clean energy, while the port's thermal system captures waste heat from industrial plants and transports it through a network of pipes to heat homes and urban buildings. In this way, the port literally completes the thermodynamic cycle of energy in its metropolitan environment.

The real technological leap lies in the evolution of the port business model. The Rotterdam Port Authority not only manages logistics, but also administers material and energy flows, transforming the site into a circular refinery where no waste ends up in the sea. This approach meets the most ambitious goals of the European blue economy and transforms the port into a catalyst for industrial innovation and applied sustainability.

For the Spanish port platform, the Dutch case represents a roadmap towards sustainable competitiveness. While Singapore leads in terms of data management and Rotterdam in energy circularity, Spanish ports have a strategic opportunity to adapt these models through innovation funds and public-private cooperation.

Brine-fed electrolytic reefs

Port innovation and marine sustainability are making progress thanks to initiatives promoted or supported by the Balearic Islands Port Authority (APB), which acts as a catalyst for new technological solutions in the maritime and port spheres. Among the outstanding projects is the proposal Brine-fed electrolytic reefs, developed by Irp engineering and the University of Alicante and a finalist in the Timón Awards, in which the APB is a partner.

This innovative solution turns waste brine from desalination plants into an opportunity for ecological regeneration. Its technology allows reefs to be "grown" through electrolysis processes on light metal mesh placed at discharge points, exploiting the high ionic concentration of the brine to accelerate the formation of a calcium carbonate and magnesium carbonate coating‑. The result is a structure with a texture and porosity similar to that of a natural rocky substrate, suitable for the colonisation of filter-feeding benthic communities.

Once the desired thickness and roughness conditions are achieved, these modules are installed in marinas and ports as green infrastructure, contributing to increasing biodiversity and improving the quality of the port ecosystem. In addition, the proposal incorporates an underwater observatory suspended from fixed or floating pontoons, with glass floor sections that enable direct observation of the reef and its development, together with salinity, pH, turbidity and temperature sensors. Its integration of educational and environmental communication components reinforces the link between the port and the general public.

The project exemplifies the type of applied and sustainability-oriented innovation that the APB seeks to promote: solutions that not only mitigate impacts, but also generate environmental, social and informative value in the Balearic Islands port environment.
