Energy demand
Economic development requires abundant, reliable energy. Fossil fuels still dominate that demand despite their environmental cost.
About Salacia
A circular vision of energy, drawn from the sea.
Salacia was founded on a simple conviction: ecology and economic growth are not opposing forces. They can — and must — be reconciled through better industrial systems and better energy models.
01 · Our Story
From conviction to company.
Salacia — Sustainable Solutions was founded in France in 2025 by engineers François-Melchior Le Tourneau and Oscar Paetzold, driven by the belief that ecology and economic growth can be reconciled through better industrial systems and better energy models.
The founding vision emerged from a deeper analysis of how modern economies function. Durable economic development remains inseparable from access to abundant, reliable energy — yet fossil fuels still occupy a disproportionate and unsustainable place in that equation.
The founders investigated alternatives, including conventional biomass, before identifying the structural limits of terrestrial biomass: land-use constraints, competition with agriculture, and limited scalability. That analysis led them to a strategic resource far larger and far less exploited — marine biomass.
From that insight, Salacia was established to develop a new generation of sustainable solutions capable of producing renewable energy and low-impact materials, while supporting industrial competitiveness, ecological responsibility, and greater national and regional sovereignty — especially for France and the European Union.
A feedstock with material character
Sargassum and other macroalgae carry a distinct biochemical profile: water content, lipids, minerals, and organic polymers that make them candidates for thermochemical conversion. What appears as waste is, in fact, feedstock.
02 · The Challenge
Decarbonization without dismantling the economy.
Modern economies depend on engines, transport systems, storage networks, and industrial logistics designed around liquid fuels. Replacing all of that infrastructure overnight is neither feasible nor financeable — but leaving it unchanged is not an option either.
Land-based limits
Terrestrial biomass faces unavoidable ceilings: finite arable land, direct competition with food production, and constrained scalability.
Infrastructure inertia
Real-world decarbonization must work with the transport, storage, and industrial systems already in place — or it will not happen at scale.
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
03 · Our Approach
Marine biomass, transformed for the infrastructure of today.
Salacia is developing a disruptive technological solution to transform macroalgae biomass into low-cost renewable fuels and other sustainable outputs — compatible with existing engines, transport systems, storage networks, and industrial logistics.

Drop-in fuel
Circular & resilient
This compatibility is deliberate. By producing drop-in fuels rather than requiring entirely new infrastructure, Salacia enables near-term decarbonization without waiting for the replacement of the systems modern economies depend on.
Beyond the technology itself, Salacia is designing a broader lifecycle-based economy — one in which waste is minimized and resources are systematically reused, recaptured, retransformed, and revalorized. The goal is not only to reduce carbon intensity but to restore resilience and autonomy to strategic sectors.
Thermochemical conversion — at the core of our process
Our process centers on thermochemical conversion: controlled temperature and pressure conditions that break down complex organic matter into liquid fuel precursors. No drying step. No land requirement. Built for marine feedstocks.
- Marine collection: Macroalgae & coastal biomass
- Pre-processing: Preparation & conditioning
- Conversion: Salacia transformation
- Fuel outputs: Renewable drop-in fuels
- Co-products: Circular valorization
- Resilience loop: Local industrial re-use
