Synopsis : In a country flooded with salt water, Bangladeshis build a new ground by extracting salt from seawater, pervasive in most parts of the country. Able to reconfigure seawater desalination techniques (already used today in the middle east), they transform the brine (obtained through electrodialysis) into a construction material. The sodium chloride present in the water passes from a disordered liquid state to an ordered rigid material. Thereby, salt, once responsible for the biotic transformation of Bangladesh and the disappearance of good soil, is being used in the development of an artificial, hybrid nature of architectural elements and rocks salt.
