TECHNOLOGY FOCUS - BIOLOGY - Preferred Components: The system further comprises an oxidation unit for treating the pollutant-contaminated fluid stream before being received in the scrubber, where the oxidation unit oxidizes nitrogen monoxide in the pollutant-contaminated fluid stream. The bioreactor comprises: at least one chemostat formed with a conduit for growing algae in it, where the chemostat includes the input port for receiving the scrubber solution and for receiving a nutrient mix to form a medium for maximum algae growth, and the chemostat has an output port for passing the medium with algae growth from the conduit of the chemostat; a means for continuously moving the medium through the conduit of the chemostat at a predetermined fluid flow velocity; a plug flow reactor formed with a conduit having an input port for receiving the medium with algae growth from the chemostat; and a means for adding a modified nutrient mix to the medium with algae growth in the plug flow reactor, where the modified nutrient mix comprises a limited amount of a selected constituent to trigger high oil production in the algae growth. The device for processing the algae to form biofuel comprises: an apparatus for lysing the algae cells removed from the conduit to unbind oil within the algae cells; an oil separator for withdrawing the oil from remaining cell matter; and a reactor for receiving the oil from the oil separator and for synthesizing biofuel and glycerin from the oil, where the remaining cell matter is a byproduct and the glycerin is a byproduct, and the device for processing the algae further comprises a means for recycling at least one byproduct to the bioreactor to support growth of algae cells with high oil content. Preferred Method: The method further comprises: treating the pollutant-contaminated fluid stream before the scrubbing step, where the treating step includes oxidizing nitrogen oxides in the pollutant-contaminated fluid stream; continuously moving the medium through the conduit of the chemostat at a predetermined fluid flow velocity; and adding a modified nutrient mix to the medium with algae growth in the plug flow reactor, where the modified nutrient mix comprises a limited amount of a selected constituent to trigger high oil production in the algae growth. The processing step includes: lysing the algae cells removed from the conduit to unbind oil within the algae cells; withdrawing the oil from remaining cell matter; and synthesizing biofuel and glycerin from the oil.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The pollutants comprise carbon dioxide, sulfur oxides or nitrogen oxides. The scrubber solution comprises sodium hydroxide or sodium bicarbonate.
