The Great Atlantic Sargassum Belt, a thick mass of leafy, floating seaweed stretching across thousands of miles of ocean, is forecast to be a nuisance of record-breaking proportions this year.
Sargassum contains high levels of arsenic and heavy metals, organic contaminants, and marine debris. When it dries, it releases hydrogen sulfide, a gas that smells like rotten eggs and can cause respiratory problems.
Seaweed Greens has discovered how to remove these pollutants and turn sargassum into high-quality organic fertilizer and regenerative products.
