The problem

Coastlines are being overwhelmed

Climate change is taking its toll on our coastlines. Nations around the globe, from Puerto Rico to Barbados, are witnessing record amounts of sargassum choking their shores. These invasive blooms devastate wildlife, threaten tourism, and even affect the health of locals.

The solution

Collection is the beginning of the value chain

The Ocean Harvester is being developed to collect sargassum offshore before it reaches the beach and decomposes. Its strategic role is to help secure suitable biomass as feedstock for local biorefining — connecting collection with extraction, ingredients and industrial markets.

Its role in the Thalasso model

From collected biomass to valuable ingredients

The Harvester supports a larger processing-led system. Collected sargassum is intended to move into Thalasso's modular Micro-Biorefinery, where the biomass can be separated into valuable fractions including the platform's intended principal product lines: fucoidan, alginate and biostimulants.

Big impact, small emissions

Electric propulsion using proven aquatic technology — harmless to marine life and quiet in operation.

Stable at sea

Purpose-built for rough water conditions where most surface harvesters struggle.

100% autonomous

Unmanned operation, remotely controllable from the beach or from anywhere in the world.

High tech, low hassle

Designed for scalability, so a fleet can take on the capacity a region actually needs.

Available harvesting solution

Sargassum harvesting vessel by Máquinacero

Thalasso works with Máquinacero to offer a purpose-built vessel for collecting floating sargassum directly from the water, helping intercept biomass before it reaches beaches, marinas and coastal infrastructure.

The vessel can operate as a standalone collection solution or as part of a wider Thalasso sargassum management and processing system.
