Las Salinas remediation process moves forward with the beginning of excavations


The urban regeneration project in Viña del Mar took a new step forward with the official start of the operational phase in the South Section. This stage involves the necessary excavations of the land to collect the soil and form biopiles, a central technique in the bioremediation process that will allow the land to be decontaminated in a controlled and environmentally safe manner.

During this phase, samples will be taken and the soil will be classified, separating clean material from that which requires treatment. Then, biopiles -mounds designed to harbor microorganisms present in the soil- will be installed to naturally degrade contaminants, allowing for progressive progress in the site’s recovery.

The South Section is expected to be completely remediated by the end of 2027, giving way to the treatment of the North Section in 2028. The project involves an investment of US$1.3 billion, the generation of nearly 70,000 direct and indirect jobs, and the creation of a sustainable waterfront neighborhood with green areas, public spaces, stores, and mid-rise buildings.
