Solution Pitch


The Problem

Sargassum invasions, driven by climate change, have severely impacted coastal communities, threatening ecosystems and public health, while affecting tourism and fishing. In 2023, over 20-million tons of sargassum were reported. Simultaneously, the agricultural crisis, fueled by reliance on synthetic fertilizers, contributes to environmental damage and CO2 emissions, exacerbating climate change.

The Solution

"Harvesting Hope from the Sea" is an innovative solution that transforms the environmental crisis of seaweed invasions, such as sargassum, into an opportunity for sustainable development. By collecting and processing sargassum from affected coastal areas, the project converts this macroalgae into valuable products. Currently, two main products have been developed: Marine Symbiotic, a biostimulant for agriculture that enriches soil, enhances crop yields, and reduces reliance on synthetic fertilizers, thereby promoting eco-friendly farming practices; and Marine Blossom, a product designed to extend the lifespan of fresh flowers. The solution engages local fishermen in the seaweed collection process, providing them with sustainable livelihoods and boosting the blue economy in the region to empower coastal communities. Ultimately, it aims to mitigate the hazardous impacts of sargassum, enhance environmental resilience, and create a thriving blue bioeconomy in the Caribbean.

What specific problem are you solving?
Seaweed invasions like sargassum are a growing global threat, affecting over 50 countries, generating more than 40 million tons annually, causing over USD 1.5 billion in losses, and endangering public health and ecosystems—a crisis rooted in unsustainable, synthetic and fossil-based industries such as agriculture, cosmetics, and materials.
What is your solution?
SOS Biotech (Sustainable Ocean Solutions for biotechnology) is a biotech company that provides an integrated solution across the full value chain of invasive seaweed management, from harvesting and environmental sanitation to processing and upcycling biomass (such as sargassum seaweed) into bio-based, low-carbon products. Seaweed is collected across multiple affected coastlines, delivering coastal clean-up services while securing sustainable feedstock for scalable biorefining. The resulting products are primarily focused on agriculture, reducing dependence on synthetic fertilizers while increasing crop resilience and protection against climate stress; these include Marine Symbiotic, Marine Soil, Marine Blossom and Marine Growth. SOS Biotech also develops high-value extracts and bioactives for adjacent sectors such as cosmetics, nutraceuticals, and biomaterials, including Atabey’s Nectar, Chlorovita, Escumaqua, and Alginaqua. By operationalizing ocean restoration through climate-smart agriculture and circular biorefineries, the solution turns invasive seaweed into a scalable climate asset powering low-carbon products, strengthening coastal livelihoods, and transforming industrial supply chains.
Who does your solution serve, and in what ways will the solution impact their lives?
Our integrated value chain enables SOS Biotech to directly benefit diverse stakeholder groups across coastal, agricultural, and industrial systems. Through invasive seaweed removal and environmental sanitation services, we support entire coastal communities in affected regions, including fishers, tourism operators, and local residents, improving public health, coastal ecosystems, and economic stability. In particular, fishers benefit from formal employment opportunities, training, and more stable incomes through participation in seaweed harvesting operations, strengthening livelihoods in climate-vulnerable coastal areas. Through our upcycle seaweed bio-based products that replace synthetic inputs, we benefit farmers and agricultural suppliers by improving soil health, increasing crop resilience to climate stress, and reducing dependency on synthetic fertilizers. Finally, by supplying seaweed as a raw material and specialized seaweed extracts to industries such as cosmetics, biomaterials, and nutraceuticals, we enable companies and consumers to reduce their carbon footprints and transition toward lower-carbon, climate-smart and ocean-positive value chains.
