SEPROSYS internal development

Our internal R & D activity allows us to develop new separation processes, as well as the applications of molecules extracted and purified according to our processes.


We have developed a marine macroalgae fractionation process line to recover polysaccharides, proteins, pigments and mineral salts.

In collaboration with the University of La Rochelle, we study the biological activities of these fractions.
