A circular vision of energy, drawn from the sea.

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.

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.

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.
