Turning sargassum into drop-in fuel.
Salacia transforms marine biomass into renewable fuels and low-impact materials - compatible with the engines, networks and industries today’s economy already runs on.
Building the future where economic growth and sustainability are compatible.
A coastal burden measured in millions of tonnes.
Every year, sargassum strands on Caribbean and West African coasts - smothering beaches, releasing hydrogen sulphide as it rots, and forcing costly clean-ups. Today it is treated as waste. It is, in fact, an under-used feedstock at industrial scale.

Beyond the limits of terrestrial biomass.
Conventional biomass faces structural constraints that limit its scalability. Marine biomass offers a fundamentally different resource base.
Terrestrial biomass
- Land use pressure
- Freshwater competition
- Food & feed conflict
- Agricultural constraints
- Scalability ceiling
Marine biomass
- No arable land required
- Vast marine resource base
- Coastal valorization potential
- Wet biomass compatible
- Circular industrial model
From the shoreline to the fuel tank, in three steps.
Wet macroalgae go in; liquid fuel precursors come out. No drying step, no arable land, no new distribution network.
-
01
Collection
Sargassum is collected at sea and on shore by coastal partners and conditioned for processing.
-
02
Thermochemical conversion
Controlled temperature and pressure break down the organic matter into liquid fuel precursors - built for wet marine feedstock.
-
03
Drop-in fuels
The liquid fractions are refined toward diesel-like, marine and, in time, aviation routes that existing engines already accept.
From coastal burden to industrial resource
Marine biomass stranding along tropical and subtropical coastlines is both an ecological challenge and a strategic opportunity. Salacia’s process begins where the problem is most visible - transforming what arrives on shore into a clean, scalable industrial feedstock.
Early-stage, and specific about it.
Salacia is at laboratory proof. Here is what is in place today - no more, no less.
- Roadmap Phase 1 of 6 - laboratory proof Integrated batch process chain, 2026–2027
- Research Mines Paris – PSL Thermochemical conversion, high-pressure processes, experimental validation
- Supply French Departments of the Americas Coastal collection partners; site of the first industrial demonstration
- Company Founded 2025 in France Engineer-led SAS, supported by Pépite PON
