🗞️ Driving the news: Grenada is leading an ambitious regional effort to transform sargassum seaweed — an annual environmental and economic menace — into a source of renewable energy, fertilizer, and green products
• With support from the EU and growing private-sector interest, the island nation plans to process 10,000 tons of sargassum by 2026
• Startups like SarGas are already converting sargassum into biofuel, powering bakeries and eyeing electricity generation for the national grid
🔭 The context: Since 2011, massive blooms of sargassum — fueled by rising ocean temperatures and nutrient runoff — have inundated Caribbean shores each summer, affecting tourism, fisheries, and coastal health
• Removing the decaying algae costs millions annually and emits methane when dumped
• Grenada’s strategy, developed with partners such as Último Recurso and Climate Analytics, seeks to convert this burden into an asset through biogas generation, sustainable fertilizers, and even cosmetic ingredients
🌍 Why it matters for the planet: Repurposing sargassum aligns with climate goals by reducing methane emissions, cutting diesel use, and enhancing regional energy security
• Bioenergy derived from local seaweed can replace imported fossil fuels, reducing costs and emissions while supporting circular economies in vulnerable island states
• However, technical and financial barriers — from heavy metal content in seaweed to the cost of bio-refineries — highlight the need for targeted investment and infrastructure
⏭️ What's next: Grenada is poised to select pilot companies this summer to begin scaling sargassum processing
• Efforts will also focus on forecasting systems, floating barriers, and international partnerships to stabilize supply chains
• Meanwhile, startups like SarGas aim to expand production capacity, and international firms are exploring higher-value exports
💬 One quote: “We shouldn’t just see sargassum as a menace, but as an opportunity.” – Jerry Enoe, Grenada’s special envoy for oceans
📈 One stat: Grenada’s first planned sargassum-to-energy plant could process up to 8,000 tons of seaweed per year, generating electricity while avoiding the emissions of approximately 2,000 cars
