Semi-aerobic (Fukuoka Method) landfill  Design/Supervision of construction/Technical advisory services

Technology / Service Summary

The "Semi-aerobic landfill structure" is to accelerates the stabilization of landfilled waste, promotes aerobic decomposition of landfilled waste, decrease of emission of greenhouse gases


Promoting the landfill internal atmosphere to be aerobic status, accelerating the stabilization of landfilled waste, promoting the aerobe decomposition of landfilled waste to suppress the emission of greenhouse gases such as methane and trying to accelerate early stability of leachate quality


By laying a perforated leachate collection pipe at the bottom of the landfill, placing crushed gravel . on it, and keeping the end of the leachate collection pipe over the top of the water surface level such as water collection pond, in order to enable to take air into the landfill layer through the pipes.


Methane gas and hydrogen sulfide suppression, odor improvement, early stabilization of landfills, improvement of water environment inside and outside the landfill site, early stabilization of leachate quality, and cost reductions related to spraying drugs during maintenance and management of the landfill

In Japan, there are more than hundreds of design and construction supervision work for the semi-aerobic landfill.
In Overseas, there are the following project reference;

1. Thailand / Tak province
Technical advisory of design and construction of new semi-aerobic landfill
Start of using: November 2016, landfill capacity: about 8,000m3 (L55m x W30m x d5m)

2. Palau / State of Aimeliik
Design and construction supervision work of new semi-aerobic landfill (participated as a JV member)
Start of using: November 2020, landfill capacity: about 385,000m3

3. Liberia / Cheesemamburg landfill
Technical training seminar for Japan's landfill technology (semi-aerobic landfill) related to the construction of new landfill funded by the World Bank (the work collaboration with Kyushu University)
