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.

International presence

How the brand leaves Spain

Ecoalga does not open a subsidiary in every country: it licenses the brand to an importer who knows the market and supplies product, local-language labelling and sales material. Romania has worked this way for several years, with country exclusivity and its own brand campaigns, including sponsorship of a mountain race.

Markets with active distribution: Spain and Romania.
