Development of the <strong>Fukuoka</strong> Method(Semi-Aerobic LandfillStructure)<strong>Fukuoka</strong> <strong>City</strong>’s landfill around 1970(Hatta Landfill )Until the 1960~70s、Japan, like many other Asian countries today, usedanaerobic landfillsLead to environmental problems suchas toxic leachate and foul odorThe start of experiments to improve landfills, aimingto purify leachate
Experiments <strong>by</strong> <strong>Fukuoka</strong> <strong>City</strong> and <strong>Fukuoka</strong> UniversityAn Test Plant was constructed at Hisayama Landfill in 1973Left: Aerobic landfill experiment, Right: Improved anaerobic landfill experiment
Impact of <strong>Fukuoka</strong> Method: Leachate TreatmentAnaerobic landfill90%decomposedSemi-aerobic landfill99.9%decomposedAnaerobicAerobicAerobic landfillPassage of time (years)Improvement over time of the landfill structure and leachate’s biological oxygendemand (BOD) (combusible waste)
There are essentially 3 landfill <strong>method</strong>s1AnaerobicWaste• High emissions of harmful substances such as CO2,methane, etc• Waste is in a leachate state2AerobicWaste(Cross-section)• Relatively less emission of harmful substancessuch as CO2, methane, etc• Easy treatment of leachate• High cost of construction and maintenance<strong>Fukuoka</strong> Method3Semi-aerobic (Cross-section) • Relatively less emission of harmfulsubstances such as CO2, methane,etc• Easy treatment of leachate• Low construction andmaintenance costs14
