Outline of Final Research Achievements

The main finding of this study is the air pathway in landfill and its mechanism. By use of gas tracer test in full size landfill, air is induced from leachate collection pipe, and it moves through solid waste layer, then discharged to passive gas vent. This mechanism was well matched with natural ventilation model. Because temperature and gas velocity can be index to know the magnitude of aeration around gas vent, extensive survey was conducted to know the degree of aeration in municipal and industrial solid waste landfill. Since gas flow was detected in a landfill in which leachate is accumulated at the bottom, gas vent is primarily important to provide exit and air can be induced from peripheral gas vents instead of leachate collection pipe.
