01 · What we do

A new generation of solutions, built from the sea.

Salacia transforms under-used marine biomass into renewable energy and sustainable materials, reconciling ecological responsibility with industrial competitiveness.

Marine biomass valorization

Macroalgae is a largely untapped resource — abundant, non-competing with agricultural land, and rich in convertible energy. We turn it into industrial value.

Low-cost renewable fuels

Fuels designed for the engines, transport systems, and logistics networks of today — decarbonization without requiring the replacement of existing infrastructure.

Circular industrial model

A lifecycle-based approach where waste is minimized and resources are systematically reused, recaptured, and revalorized across the value chain.

02 · Our Mission

Positioned at the intersection of energy transition, industrial innovation, and sovereignty.

Salacia is developing a disruptive technological solution to transform macroalgae biomass into low-cost renewable fuels and other sustainable outputs — supporting industrial competitiveness, ecological responsibility, and strategic autonomy.

04 · Team

Engineers building the sustainable energy model.

Salacia was founded in 2025 by engineers with the conviction that ecology and economic growth must be reconciled through better industrial systems.
