The transformation of the Tres Xemeneies area into a residential and tech hub with 1,783 homes requires addressing a legacy of industrial pollution. Studies costing 350,000 euros will identify toxins from former paint and pesticide factories. Private firms like Inditex will also invest over 5 million euros to clean their designated plots in the Avinguda de la Platja sector.

While land decontamination is synchronized with the 2027-2033 construction schedule, the coastal area remains a concern. The Ministry for Ecological Transition has yet to set a date for cleaning heavy metals from the beaches, which have been closed to the public for a decade due to health risks.
