From the shoreline to the factory, Orev sustainably transforms ocean resources
into effective biosolutions for agriculture.
Seaweed and marine shells contain active molecules essential for plant growth and resilience. For over 20 years, Orev has been developing scientific processes to extract and concentrate these active compounds, transforming them into sustainable biosolutions.
At Orev, we oversee every stage of marine raw material transformation:
Valorization of local seaweeds (kelp, fucales…) and marine shells sourced from responsible supply chains in Brittany.
Cleaning, grinding, and preparation of biomass to preserve the integrity of active compounds.
Specific processes to isolate oligosaccharides, glycine betaines, hexols, and natural surfactants.
Development of marine extracts rich in active molecules, stable and standardized.
Combining these extracts with fertilizing elements (macro, secondary, and trace nutrients) to create biosolutions tailored to crops.
Laboratory and field trials to ensure performance and regulatory compliance.
By valorizing seaweed and shells from the local economy, Orev actively contributes to the circular economy. Each ton processed helps reduce dependence on chemical inputs and limits nitrogen and phosphorus discharges into the ocean. This is the guarantee of a more sustainable model that respects ecosystems.
At Orev, the sea is not just a backdrop: it is the source of modern, high-performance, and sustainable biosolutions, serving farmers and future generations.
