The Sargassum crisis is missing critical infrastructure

Seasonal sargassum influx has become a persistent operational and economic threat across the Caribbean and Gulf regions. It damages tourism, erodes coastlines, and costs hundreds of millions annually — with zero value recovered.

45M tonnes

$200K+ per hotel

99.9% wasted

Annual sargassum biomass in 2025.  

Average large resort annually spend on reactive cleanup. No end in sight. 

Biomass lost to decomposition before value can be exracted

Reactive cleanup treats symptoms. SANDS is built for prevention.

T H E S O L U T I O N

The missing infastructure layer for the sargassum supply chain.

SANDS builds containerized, automated hardware that harvests sargassum fresh and preserves biomass quality for downstream processing, bridging the core logistics bottleneck that has prevented the supply chain from scaling.

Incentives to harvest seaweed before it rots, contaminating the beachfront and coastal environment.

Captures seaweed before it decomposes. Reduces transport volume by 8x via on-site pre-treatment.

A 40' shipping container in a hotel's service area — 2-3 tonnes/hr capacity, fully automated.

Stabilizes alginate, fucoidan, and other polysaccharides before bacterial decomposition destroys value.
