As the climate heats up, Grenada’s beaches have become swamped with rotting sargassum. But biotech can turn it into fuel, fertiliser and plasticPhotographs by Haron ForteauIt is hard to describe the putrid stench of the decaying sargassum seaweed blanketing miles of shoreline in Soubise, a fishing village in Grenada. The pungent odour wafts into passing vehicles, persisting long after they have left the Caribbean island’s coves, where the ocean has deposited masses of the seaweed, which turns red then black as it rots.Many residents of Soubise, one of the areas worst affected, say they have learned to live with the problem, which has plagued the island, and others like it, for years. Last week scientists in Florida said they thought they had identified a weather phenomenon in 2009 as the “tipping point” of the problem, which they said is caused by shifting winds churning up the ocean and bringing deepwater nutrient concentrations to the surface.Lindon Marast says the seaweed clogs t...
Sargassum seaweed accumulation plagues Caribbean shorelines, causing stench, economic disruption, and health concerns. However, initiatives are underway to transform this nuisance into a valuable resource, using biotech to convert it into fuel, fertilizer, and bioplastic. Companies like Seafields and SarGas are pioneering the process, with pilot projects demonstrating the feasibility of biogas production and the potential for a multibillion-dollar export market, offering economic and environmental benefits.
