The heritage protection entity ARK has asked the Balearic Islands Port Authority (APB) not to grant the concession for the future liquid waste plant planned for the port of Palma, as it believes that it would directly affect the heritage value of the San Carlos Castle"One of the most valuable elements" of the area.

The MÉS party for Mallorca has revealed the Balearic Islands Port Authority's (APB) project to build a "major liquid waste facility" at the Sant Carles dock in the port of Palma. This infrastructure would be designed to manage flammable and hazardous materials, including those originating from outside the port. The eco-sovereignist party warns that this initiative poses "an immediate and serious threat" to Sant Carles Castle and the Portopí Signal Tower, both listed as Cultural Heritage Sites (BIC). MÉS's representative in Congress, Vicenç Vidal, and the MÉS spokesperson for Palma, Neus Truyol, explained at a press conference that the project violates heritage protection regulations and demanded urgent action from all the administrations involved. "Turning this space into a waste disposal plant is an attack on heritage, the landscape, the environment, and common sense. No responsible government should allow it," Vidal declared.
