Invasive sargassum blooms and surging organic waste are wreaking havoc on coastal ecosystems and economies—especially across the Caribbean, Mexico, and, more recently, Africa. Sargassum blooms have surged by 600% over the past decade, impacting more than 300,000 livelihoods in the Caribbean alone. These invasive mats stagnate in shallow bays, blocking access to ancestral fishing grounds and forming dense layers that choke coral reefs, seagrass beds, salt marshes, and mangroves—ecosystems vital for carbon storage, biodiversity, and coastal protection. Gravely, 90% of coral reefs are projected to die off by 2050. Marine species like fish, dolphins, and lobsters become entangled; sea turtles and seabirds lose critical nesting grounds. In 2021, over 1.3 million tons of sargassum washed ashore, disrupting fisheries, deterring tourism, and threatening public health as it decomposes, releasing methane and heavy metals into the environment. At the same time, intensifying storms and hurricanes are generating massive volumes of palm fronds and woody debris. Organic waste now makes up 33% of landfill volume, producing up to 70% of methane emissions—a greenhouse gas 25 times more potent than CO₂. Together, these dual crises are accelerating ecosystem collapse, deepening poverty, and heightening food insecurity across already vulnerable coastal regions.

Every year, mountains of sargassum invade coastlines and rot onshore. Simultaneously, worsening storms bury communities in fallen palm fronds and green waste. But what if these twin crises could power a solution? We’ve created a circular, community-powered model that transforms organic waste into new life. Partnering with local communities, resorts, and governments, we intercept sargassum before it decays in bays or on beaches. Electric boats, carts, and UTVs collect it ecologically, alongside storm debris—minimizing harm to shorelines and preventing methane release. At our upcycling sites, the biomass is shredded, sorted, and transformed. Through pyrolysis, we create biochar that locks away carbon and restores soil. Using windrow composting techniques, we produce nutrient-rich compost blends. And with our proprietary microbial formula, we neutralize the heavy metals often found in sargassum—ensuring safe, regenerative soil products. The result is a closed-loop system that diverts waste from landfills, sequesters carbon, and revitalizes land for small farmers, orchards, and reforestation efforts. With additional investment, we can also scale renewable energy generation during processing. Modular and locally driven, our model is designed to adapt globally—turning crisis into opportunity for coastal communities everywhere.

Our solution is designed to directly support the coastal communities most affected by sargassum blooms and green waste. Take the tourism-dependent resorts and local governments, for example—millions of dollars are spent annually to support these communities, but when beaches are covered in rotting seaweed, tourism plummets, and so does income. Then there are the small artisanal fisheries, whose ancestral fishing grounds are blocked by dense mats of sargassum, leading to a drastic decrease in fish catches and threatening their livelihoods. We also work with small farmers and orchards, such as the 150 women in Mexico who run nearby plantations. These farmers struggle with declining soil health due to erosion and lack of regenerative inputs. Our solution creates a circular, community-powered model that addresses all these challenges. By intercepting and upcycling sargassum and storm debris, we’re helping to clear shorelines, restore soil, and create economic opportunities—turning waste into valuable resources. The result? A revitalized ecosystem, increased resilience, and a brighter future for coastal communities that rely on the ocean, agriculture, and tourism to thrive.
