Unlocking thevalue of seaweed
Our oceans are out of sync. Thalasso builds tools to scale seaweed management, bringing balance to the ocean and benefits to coastal communities.
The challenge
Our coastlines are being invaded
Climate change has caused unprecedented blooming of sargassum — and it's threatening coastal economies, livelihoods, and ecosystems.
Balancing ecosystems
When seaweed grows where it's supposed to, it promotes healthy oxygen levels, creates a refuge for marine life, and improves the health of coastal ecosystems.
Promoting tourism
Proper management of harmful algal blooms avoids having to close beaches and promotes touristic activity on the shorelines.
Supporting communities
From fishing to harvesting, a healthy seaweed ecosystem provides vital livelihood opportunities for coastal communities.
Boosting economies
A valuable resource, seaweed can be transformed into valuable end products from plastic alternatives to biofertilizers.
How we work
A practical approach for community-led sargassum management
01
Bloom
We coordinate with coastal communities to closely monitor sargassum blooms.
02
Harvest
We collect the seaweed before it hits the shore and becomes a hazard.
03
Assess
We holistically assess both the negative and potentially positive impacts of blooms.
04
Value
We transform seaweed into valuable bi-products, ready to commercialize.
What we're building
Two tools, one end-to-end response
Alongside our advisory work, we're developing the physical infrastructure the sargassum challenge actually needs — from the moment a bloom appears offshore to the moment it becomes a valuable product.
In construction — halfway there
The Micro Biorefinery
A mobile, containerized biorefinery that converts sargassum into high-value chemical compounds close to the coast — keeping the value in the communities that live with the problem.

Concept in development
The Ocean Harvester
An autonomous, electric harvester built to lift sargassum out of the water before it reaches the coastline. High tech, low hassle — designed to scale into a community-led response.

Thalasso Advisory
Real-world knowledge, at your service
We've launched Thalasso Advisory to support governments, municipalities, hotel associations, ports, marinas, and businesses dealing with recurring sargassum events. Whether the challenge is collection strategies, processing opportunities, infrastructure planning, or long-term management, we're always happy to discuss practical, science-based solutions.

From Coastal Crisis to Blue Economy Opportunity
As record amounts of sargassum continue to impact coastlines across the Caribbean and other regions of the tropical Atlantic, it is becoming increasingly clear that this is no longer a seasonal inconvenience, but a long-term environmental and economic challenge. Recent research and media coverage point to the need for a shift in strategy - from reacting after the seaweed reaches shore to managing it proactively offshore.

Why We Believe Distributed Modular Biorefineries Are the Future of Sargassum Management
At first glance, large centralized processing plants seem like the obvious answer to the sargassum crisis. In reality, the challenge is far more complex. Here's why we believe a modular approach makes more sense.

Sargassum: More Than a Beach Nuisance
Sargassum is more than a beach nuisance. As it decomposes, it can affect public health, damage infrastructure, and create significant economic challenges for coastal communities.
