The bioeconomy is a new and essential paradigm for reducing our dependence on natural
resources and responding to the environmental threats that the Earth is currently facing. In
this regard, microalgae offer almost unlimited possibilities for developing a modern
bioeconomy given their metabolic flexibility and high biomass output rates, even when
produced under harsh conditions such as when treating wastewaters or using flue gases. In
this article, the microalgal contribution to important economic activities such as the
production of food and feed, cosmetics and health-related compounds is reviewed. Moreover,
microalgae’s potential contribution to emerging sectors is discussed, for instance, in the
production of biomaterials, agriculture-related products, biofuels, and providing services such
as wastewater treatment and the clean-up of industrial gases. The different microalgal
production technologies have also been analyzed to identify the main bottlenecks affecting
microa...
