Caution for application of "Fukuoka Method" (Semi-aerobic landfill technology)

Abstract

The “Fukuoka Method” is a technology for activation of reduction of organic material using aerobic microorganisms through providing an aerobic environment to the extent possible inside landfills to lessen the burden on the environment and promote stabilization. However, unless there is a minimum amount of moisture in the landfill layer, the microorganisms are not active and degradation also does not make progress. Therefore, in regions where precipitation is low, in addition to ensuring a soil covering to the extent possible for preventing the landfill waste material from drying out, storage, and circulation of leachate in the landfill must also be considered to ensure that leachate does not flow out of the landfill and to ensure there is a sufficient amount of water in the landfill.
