Abstract
The recovery of carbon dioxide (CO_2) is one of the most important topics to improve global environments. The exhausted gases from power generator using petroleum and coal or incinerator include more than 10% of CO_2 which is excellent source for the multiplication of plants in which photosynthesis occurs with CO_2 and water. The higher the concentration of CO_2 is, the more the reaction rate gains. We have studied and found the species of green algae useful for recovery of CO_2 and the proper condition to best growth of the algae under the high concentration of CO_2 in a continuous flow water bath. However, the contact of solid (green algae) and gas (CO_2) is difficult to manage in the industrial scale. The whole system, the target and the technology will be presented.
