Integrated microalgae-based biorefinery for wastewater treatment, industrial CO2 sequestration and microalgal biomass valorization: A circular bioeconomy approach
Open accessAbstract
Microalgae are widely used in a variety of fields, including agriculture, the environment, medicine, cosmetics, food, and feed. They are used as feedstock for sustainably produced chemicals and biofuel. However, the production of microalgal-derived products is economically unprofitable. Integrated biorefinery based on microalgae-derived products is one of the long-term solutions that could be economically and environmentally viable with zero waste. This review emphasizes the integration of wastewater treatment with CO2 biosequestration from industrial flue gas and proposes an integrated biomass valorization strategy based on microalgae biorefineries. A model of integrated biorefinery with a techno-economic analysis and the possible microalgae-derived products that can be valorized after domestic wastewater and flue gas use as low-cost inputs for microalgae culture are also proposed.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
