Abstract
A CO.sub.2 fixation system for fixing Co.sub.2 gas existing in the atmosphere or in an exhaust gas emitted from factories and other burning sites. The system includes a fermenting tank for anaerobically fermenting organic wastes, whereby methane gas is produced. The methane gas is decomposed and hydrogen gas is produced. The hydrogen gas is reacted with the CO.sub.2 gas to produce carbon powder and water, whereby the CO.sub.2 gas is fixed to become harmless to the global warming.
