Methane gas produced according to an anaerobic digestion of organic wastes is introduced into digested separated water which is alkalized by a photo-culture of algae, whereby impurity carbon dioxide gas is removed by absorption. Accordingly, methane of high concentration is recovered and at the same time, by-product algae is recycled as feedstock, and thereby improving the yield of methane.
