Algal biomass dual roles in phycoremediation of wastewater and production of bioenergy and value-added products

Abstract Algal biomass has been gaining attention over the last decades as it is versatile and can be used in different industries, such wastewater treatment bioenergy industries. Microalgae are mixotrophic microorganisms that have potential to utilize nitrogen phosphate (nutrients) remove organic matters from streams. Phycoremediation an intriguing cost-efficient technique simultaneously heavy metals while removing nutrients matters. The cultivated produced algal a promising candidate sustainable feedstock produce biofuels (e.g., biodiesel, bio-alcohol, bio-oil) value-added products biochar, glycerol, functional food, pigments. algae suspended cultivation systems, WSP HRAP, efficient methods for shallow ponds with no mechanical aeration less required energy consumption, but when short HRT minimum evaporation losses key points PBRs recommended. It was reported biosorption bioaccumulation two techniques of phycoremediation. Studies showed among current processes conversion biofuels, transesterification lipids pyrolysis were found most techniques. This review paper investigates applications phycoremediation wastewater, productions by reviewing articles mainly published five years. Graphical abstract
