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.

02 · Impact

Three reinforcing pillars.

Ecological

Valorize an under-used marine resource, reduce fossil-fuel dependency, and build a circular model where outputs are reused rather than discarded.

Carbon reduction Circular economy Marine resource

Industrial

Produce renewable fuels compatible with existing infrastructure, preserving industrial competitiveness while accelerating the energy transition.

Drop-in fuels Infrastructure compatible Scalable process

Sovereign

Restore strategic autonomy to critical sectors - particularly in France and the European Union - through a locally integrated supply chain.
