What is the ValgOrize project?

In the marine world, there is an amazing diversity of micro and macro algae: there are several thousand species, ranging from unicellular algae to specimens several metres long.

Today, some of them are harvested from wild stocks and/or cultivated for food production.

In Asian countries, seaweed is a basic ingredient of gastronomy: fresh, dried, powdered or cooked, they exist in all these forms.

In Europe, the market is developing step by step, but stakeholders know the importance of these marine plants for the future of our food.

With their nutritional benefits and a production that seems sustainable, the algae have a bright future ahead of them.

The ValgOrize project brings together producers and scientists to work together on: « Seaweed, the solution for tomorrow’s food ».

The aim? Develop a sustainable and controlled production of micro and macro-algae and optimise processing methods in order to take care of sanitary and taste quality in Europe: two major aims to be achieved.

What is the role of Nausicaa?

As a partner of the ValgOrize project, Nausicaa confirms its commitment to a responsible and innovative use of marine resources and is fully in line with the Blue Society concept.

The promotion of algae consumption is along the same lines as the Mr.Goodfish programme. ValgOrize enables to organise awareness raising events and activities to speak about the seaweed consumption with partners and the general public.

Nausicaa is in charge of the promotion of the project and its results in France, and is using and developing its expertise in promoting seafood products to stakeholders and the general public.

Who are the partners of the ValgOrize project?


ValgOrize has received funding from the Interreg 2 Seas programme 2014-2020 co-funded by the European Regional Development Fund under subsidy contract No 2S05-17.

Get to know algae better

To eat them, you need to know how to recognize them!

Within the framework of the ValgOrize project, various education tools have been developed to raise awareness among the general public about the recognition and consumption of certain micro and macro algae.

Morphology, nutritional benefits and consumption patterns are some of the topics covered in these sheets.

As the project unfolds over time, gradually more algae species will be presented over time.

Do you know how seaweed arrives on your plate?

To answer, 5 cartoons have been created, to explain the seaweed cycle:

  1. Cultivation of micro and macro algae
  2. Harvesting
  3. Processing
  4. Consumption (culinary benefits and health benefits of seaweed)
  5. The role of algae in the treatment of polluted water

Algae are chlorophyllous aquatic marine plants without roots, leaves, flowers or seeds.

Micro-algae or microscopic algae make up the phytoplankton and are at the base of marine food chains.

What is the name of the algae culture?

1. Algae is not cultivated
2. Seaweed farming
3. Algaeculture

A – 2 : Seaweed farming




Global production of algae was 3 million tonnes in 2018.

Around 75% of the seaweed collected ends up on plates, while the rest is used as a gelling agent in the food industry.
