A research team including the CNRS and l’Université des Antilles has just launched an 18-month interdisciplinary research project, largely financed by Ademe, on the brown seaweed known as Sargassum that has periodically invaded the coasts of the West Indies since 2011. The central objective is to find a way to repurpose this seaweed, which is a cause of public health problems in the Caribbean region. The project will be presented on October 3 during the 15th Regional Cooperation Conference in the Antilles-French Guiana.
