2. Fukuoka Method~Overview of Fukuoka Method~

Development of the Fukuoka Method(Semi-aerobic Landfill Structure)

Landfill sites around 1970 in Fukuoka City

Japan, like many developing countries such as African countries today, usedanaerobic landfills and open dumping until the 1960-70s.

Environmental problems such as toxic
leachate and foul odor

Joint experiments with Fukuoka University
to improve landfills, aiming to purify leachate11Three major landfill structures① Anaerobic•High emissions of harmful substances

Wastematerialsuch as CO2, methane, etc.

•Waste is moistened in anaerobic conditions

Leachate② Aerobic

•Easy treatment of leachate•High construction and maintenancecosts. (Air-pipes are constructed topump in air into the waste layers.)

③ Semi-aerobic•Relatively low emissions of harmful
substances such as CO2, methane, etc.

2. Fukuoka Method~Fukuoka Method Global Network~Challenges and Supports to Expand Fukuoka Method

Cases ofimproper
designandconstruction

Cases oflack ofcontinual
maintenance

There caused various issues after introducing
and implementing Fukuoka Method.

In order to promote proper Fukuoka Method

Proper understanding of the basic principles of "Fukuoka Method“and human resource development are important.

Fukuoka Method Global Network(FMGN)21

The Fukuoka Method Global Network (FMGN) was established as it is important to properly understand the basic principles ofthe Fukuoka Method and to develop the human resources to use it.
