Photosynthetic carbon dioxide sequestration and pollution abatement

A system and method for producing biofuel from pollutant-fed algae are disclosed. Specifically, the system includes a scrubber with a chamber for receiving a pollutant-contaminated fluid stream. Further, a scrubber solution is received in the chamber for scrubbing the pollutant-contaminated fluid stream. Also, the system includes a bioreactor that is provided with an input port to receive the scrubber solution with pollutants for use as nutrients to support algae cell growth. Further, the system includes an algae separator that removes the algae from the bioreactor and a device for processing the algae into biofuel. In order to recycle the scrubber solution, the algae separator is in fluid communication with the scrubber. With this arrangement, the effluence from the bioreactor may be recycled for use as the scrubber solution.
