SargaCycle
SargaCycle intercepts invasive sargassum seaweed at sea before it reaches shorelines, then converts the fresh biomass into agricultural products such as liquid biostimulants and biochar. The company's offshore booms and pumps remove up to 16 tonnes per hour, and its biostimulant is designed to build crop resilience to drought, heat, and salinity while reducing reliance on synthetic fertilizers.

Problem
Invasive sargassum seaweed proliferates across the Caribbean, washing ashore in massive quantities that smother coastal ecosystems, harm tourism, and disrupt local economies. Coastal communities and environmental managers lack scalable, economically viable methods to intercept this biomass before it reaches shorelines and to prevent the ecological and economic damage it causes.
Solution
SargaCycle operates at sea to intercept invasive sargassum before it reaches coastal areas, then converts the collected biomass into high-value agricultural inputs through a circular process. The company produces liquid biostimulants that capture a unique "survival cocktail" from the seaweed, which triggers complex root architecture and enhances crop resilience to heat and salinity stress. SargaCycle also processes residual biomass into biochar, which improves soil water retention and restores soil microbiomes when applied. By replacing synthetic agricultural inputs with nutrient-dense, seaweed-derived extracts, the company helps farmers sustainably boost yields while addressing the sargassum crisis. Additionally, the operation generates high-integrity blue and green credits tied to carbon storage and ecosystem protection, creating a scalable model for climate resilience across the region.
Target Audience
Primary customers include agricultural producers and agronomy companies seeking sustainable, climate-resilient crop inputs, as well as environmental organizations and carbon credit buyers interested in verified blue and green carbon projects. The company also works directly with governments and hotel resorts across the Caribbean seeking to protect coastal ecosystems and tourism.
Features
- At-sea interception system with offshore booms and marine pumps that removes up to 16 tonnes of fresh sargassum per hour, 365 days a year
- Early-warning system combining satellite imagery (developed with the French space agency CNES) and drift models to forecast sargassum movement up to five days ahead
- Liquid biostimulant formulation derived from sargassum's natural stress-response compounds, independently third-party field-tested, promoting root development and tolerance to heat and salinity
- Biochar production from residual biomass that enhances soil water retention and supports long-term carbon storage
- Circular conversion process that transforms an environmental liability into a renewable agricultural resource stream, with nothing going to landfill
- Blue and green credit generation tied to measurable carbon sequestration and coastal ecosystem preservation outcomes
- Standardised refined sargassum supply for manufacturers, with heavy metals removed
