La Palma Implements Depressurization Systems for Volcanic Gases in Puerto Naos and La Bombilla

The Cabildo de La Palma and the Eduardo Torroja Institute collaborate on an innovative technique to extract CO2 from homes affected by the eruption.

The Cabildo de La Palma, in collaboration with the 'Eduardo Torroja' Institute of Construction Sciences, part of the CSIC, has launched a project to implement depressurization systems that extract volcanic gases in the towns of Puerto Naos and La Bombilla, following the eruption of the Cumbre Vieja volcano.

This initiative focuses on installing a technique that allows for the capture of carbon dioxide (CO2) accumulated in homes and its controlled redirection. The method involves placing specific ducts and extractors to remove CO2 from critical areas, such as basements and ground floors, and releasing it at uninhabitable evacuation points, where it naturally dissolves into the atmosphere without posing a risk to the population.

"This work is fundamental to provide certainty to residents, and the objective is to physically intervene in buildings to convert them into technically and sanitarily safe spaces."

The collaboration with the Spanish National Research Council center addresses the need for solutions backed by expertise in construction pathology and building physics. This technique complements other ongoing measures, such as the continuous monitoring sensor network and forced ventilation systems.

"This collaboration contributes to consolidating the island as an international benchmark in the application of scientific-technical solutions to catastrophes."
