Algae communities as primary producers are essential elements of aquatic ecosystems and contribute significantly to oxygen production, carbon dioxide fixation, nutrient transport processes in water bodies. The use algae-based capture storage technologies does not produce harmful by-products that require disposal, the resulting algal biomass can be valuable across various industrial sectors. In this study, model experiments were conducted develop sequential absorption–microalgae hybrid CO2-capture methods. To facilitate CO2 from flue gases, wood ash (WBA), an agricultural by-product, was utilized for its alkaline properties, while gas scrubbing medium regenerated by algae restored alkalinity during their growth. our experiments, one goals determine optimal conditions achieving maximum growth shortest possible time. suitability WBA cleaning tested via simulation introduction. Moreover, a method developed dissolved inorganic content with OxiTop device monitoring changes pressure. applied closed, static, pressure-based respirometer originally designed biological activity microorganisms both solid liquid samples. addition, effects CO2-enriched extract on cultivation also analyzed, confirming it imposed no inhibition identifying concentration (10% WBA) optimally promoted initial determined.
