Groupe Roullier

Enabling earth and mankind to produce the best



Groupe Roullier was founded in 1959 on the port town of Saint-Malo (Brittany, France). The group establishes its first facility for grinding red calcareous algae; maërl, whose particular characteristics make it the ideal conditioner for acidic soils.

 Committed for almost 60 years to Plant Nutrition, to Animal Nutrition and to the Food-industry, the Groupe Roullier leans on its industrial and technical excellence, its unique business model and a dynamic innovation labs.  Through these years, it has always continued to develop its expertise and skillsets in marine biotechnology, by launching new original amendments, fertilizers and biostimulants based on seaweed extracts, in more than 110 countries.  

 In 2016, the Global Innovation Centre Roullier open its doors in Saint-Malo. With its exceptional facilities and human expertise, focused on cutting edge initiatives to bring marine bioactive substances to market ,this new interdisciplinary state of the art facilities demonstrates the scale of the Group's ambition: to maintain its market leadership while answering  the challenges of tomorrow’s Agriculture







One major aim of the IDEALG Project (www.idealg.ueb.eu) is to consolidate and enhance knowledge and competences for the development of the macroalgae uses in France, based on major breakthroughs in the field of seaweed genomics and genetics.

 IDEALG is completing its 6th year and has provided numerous developments and consequent scientific productions. In particular, the project can highlight the development of tools for genetic, chemical and mathematic analyses to better understand the physiology, the metabolism and the growth of the seaweeds in their environment.

 The development of biological tools mainly concerns the model brown algae Ectocarpus. Quantitative genetics methods  in Ectocarpus, as well as the analysis of biosynthetic pathways of components of interest such as phlorotannins or mannitol, provided new tools that now can be adapted to new seaweed species like  Saccharina latissima that are ofcommercial interest and amenable for genetic breeding.

 Furthermore, the work in IDEALG resulted in the elaboration of the first complete maps of brown and red seaweed metabolic pathways (ECTOGEM & ChondrusGEM).

 New valorization opportunities are being pursued for applications in green chemistry notably organic surfactants, but also in the field of Hygiene and Health to fight against bacterial biofilms.

 Some bacteria associated to seaweed are sources for important molecules, especially enzymes that are used to extract the constituents of seaweed into high value added compounds for the purpose of industrial applications or to develop new  biotechnological processes.

 Impact studies on natural seaweed species are being carried out before their exploitation and the results will lead to a better management of the resources.

 In parallel, a SWOT analysis for algoculture was put in place in cooperation with the seaweed industry as a reference for decision-making processes. Moreover, the analysis of the ecosystem services for an algoculture project was useful to set up compensatory measures.

 Social and economic studies were also conducted towards the development of potential markets for edible seaweeds as well as Life Cycle Assessments of seaweed aquaculture and biorefining.

 Numerous innovative and research projects have been initiated through IDEALG, such as the H2020 GENIALG Project (www.genialgproject.eu) started in January 2017. Today, IDEALG’s collaborative platform is welcoming as many as 30 companies.



Synoxis Algae


Synoxis Algae is the brand of the French plastics processing company Synoxis, for biotechnologies.

It is specialized in design and building of micro-algae cultivation systems.

Synoxis has been involved for more than 20 years into the micro-algae sector as a plastics processing expert for different well-known research laboratories.

Synoxis Algae has developed, together with IFREMER and NANTES UNIVERSITY, an air-lift and tubular technology for Photobioreactors. Its specific feature consists into creating a whirling movement of the fluid which will significantly limit the attachment of biofilm on the pipes’ walls, therefore greatly increasing productivity of the system.

This patent protected technology has since then been adapted on LUCY, a 16-liters photobioreactor.

Efficient, accessible and agile, LUCY stems from the convergence of the worlds of sea-farming and research laboratories.

Synoxis Algae’s businesses are:

-          Manufacturing of standard photobioreactors (LUCY)

-          Design and building of customized photobioreactors

-          Development and construction of specific algae-growing equipment (paddle-wheels, pools, barrels, etc…)
