Abstract

This project aims to study the brown algae Sargassum spp. which is landing in the Caribbean region and northeast of Brazil in order to better manage the biofouling by the algae and develop methods for valorization of the biomass. Sargassum are brown algae, originally found in the Sargasso Sea, located in the Gulf of Mexico. The flow of sargassum is becoming a serious environmental problem all over the Caribbean islands. In Guadeloupe alone, around 80000 tons of seaweed are stranded during the season. Similar situation is seen around the entire Caribbean region. Since the appearance of the first waves of Sargassum algae, several methods have been put in place concerning their collection in order to keep the beaches clean. Recovery processes are highly sought because 90% of the collected algae are currently stored without recovery. The lack of research initiatives necessitates a more in-depth exploration of Sargassum algae chemistry, targeted towards innovative applications and their development. Sargassum algae control solutions must therefore meet diverse needs including environmental, health and economic purposes. The current proposal comprises two steps including optimization of the Sargassum collection methods and processing and utilization of the biomass for valorization to produce value added products for multiple uses. These two steps will be supported by Life Cycle Assessment (LCA) as an environmental strategy in decision-making. The improved collection methods will enable efficient harvest of the biomass before they reach shores. The methods of valorization include, development of phytostimulants for agriculture, use as component of building materials, preparation of filtering membrane, production of nutraceutical substances, anticorrosive or dye products and value-composts. The developed technologies will be subsequently available for pilot scale production and future licensing for commercialization. It is expected that the successful completion of the research project will yield the meaningful ways to address the Sargassum problem and effective means for utilizing biomass. (AU)
