Seaweed could help build the cities of tomorrow | A common form of seaweed, piling up on tropical beaches, could be used to make eco-friendly concrete
Once a harmless drifter in the Sargasso Sea, an algae known as sargassum is now flooding tropical beaches, from Brazil to the Caribbean, with stinky, toxic piles. As it rots, it releases gases like ammonia and methane, turning paradise into a health hazard.
Once a harmless drifter in the Sargasso Sea, an algae known as sargassum is now flooding tropical beaches, from Brazil to the Caribbean, with stinky, toxic piles. The life cycle assessment (LCA) revealed a promising finding: materials made from sargassum seaweed outperformed traditional expanded clay in terms of environmental impact. That finding led researchers to a bold conclusion: microwave-sintered sargassum clay isn’t just viable, it’s a smart way to tackle the seaweed surge along tropical coastlines.
