SargaCycle intercepts invasive sargassum seaweed across the Caribbean before it reaches shorelines, converting the biomass into agricultural biostimulants and biochar. The company's circular process transforms an environmental crisis into crop-enhancing products that improve root architecture, heat and salinity resilience, and soil health. SargaCycle also generates blue and green credits through its carbon-storing, ecosystem-protecting operations.

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.
Features
- At-sea interception system that collects invasive sargassum before it reaches shorelines, protecting coastal ecosystems and tourism infrastructure
- Liquid biostimulant formulation derived from sargassum's natural stress-response compounds, 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
- Blue and green credit generation tied to measurable carbon sequestration and coastal ecosystem preservation outcomes
