The project aims to implement on an economic scale the production and valorization of SCO's from algae and/or yeasts. A high valorization potential is expected: (1) use of high value oil fraction (EPA, GLA, DHA,...) in food application, (2) lower value fraction in biodiesel production and (3) as chemical building blocks. Second target is valorization of side streams in order to further increase economics (cell mass, CO2, organic waste, .....).
