How we work
Three commitments behind every batch
Ecoalga is an industrial supplier: each project is assessed on its application, volume and documentation needs before any commercial proposal.
Specialisation in Ulva
The whole company is built around the professional use of Ulva green seaweed, from cultivation to processing.
Controlled process
Sourcing, processing and product development under internal traceability, batch by batch.
Applied research
Scientific collaboration with public research centres to study and develop new industrial applications.
Production
Own cultivation, own processing
Ulva is harvested and processed in our own facilities in Huelva. This keeps origin, handling and batch documentation under our control, which is what industrial buyers and laboratories need.
Scientific collaborators
Research partners
Documented collaboration with public research centres, including the SEAWINES project (2021–2025) on Ulva ohnoi in viticulture.
