PURPOSE:To suppress the activity of a methanogen and to effectively decompose and stabilize an organic matter by suppressing the generation of methane in the presence of a sulfate ions in a waste matter to the extent that oozing water from the waste matter is not made acidic. CONSTITUTION:The sulfate ion (SO4) scattering to a waste piling facilities 4 is obtained by the oxidation of H2S contained in the oozing water 6 in the oozing water treatment facilities 5. In the case of shortage with only the returning sulfate ions SO4, e.g. Na2SO4 solutions may be scattered. By providing sulfur monitor 8, the concentration of the sulfur component in the oozing water 6, namely the state of sulfate ion (SO4), hydrogen sulfide ion (HS and hydrogen sulfide (H2S), etc., in the waste material layer of the waste material piling facilities is usually monitored. In the case of the shortage of sulfate ions (SO4), the increase in the quantity of the returning water or the scattering of Na2SO4 solution, etc., is used. By this method, the generation of the gaseous methane is suppressed, and, the unfavorable influence on human body and plants, etc., odor problem and the application of remaining lands are solved. Thus, this method is useful for preventing the warming of the earth's atmosphere.
