F. Gabriel Acien Fernandez is a Full Professor at the University of Almería. His main research line deals with the development of microalgae-based processes for CO2 abatement and wastewater treatment and for the production of agricultural products, animal feeds, and human food. He is also interested in the valorisation of greenhouse co-products and wastes. In this sense, Prof Acién participated in a large number of international and national projects and contracts with companies. He was the coordinator of the H2020 SABANA project, focused on the sustainable production of biofertilisers and aquafeeds from waste using microalgae and is currently the Coordinator of the SABANA Demonstration Plant located in Almería.
