This talk outlines our 2 demonstrator plants where nutrients in waste streams can be recovered and recycled in a circular economy through algae production. Microalgae consumes CO2, Nitrates and Phosphates as growth nutrients, along with sunlight, to create more biomass, a range of useful biomaterials and Oxygen. In this way, valuable products can be obtained from recycled materials resulting in a cost-effective process. Turning waste material into value added products thus reducing CO2 emissions
