Five landfills were analyzed to provide a perspective of current practice and technical issues that differentiate bioreactor and recirculation landfills in North America from conventional landfills. The bioreactor and recirculation landfills were found to function in much the same manner as conventional landfills, with designs similar to established standards for waste containment facilities. L...

Leachate accumulation was found in Nakazono landfill, in Asahikawa, Japan because of an insufficient leachate collection and drainage system. In order to lower leachate level in the landfill and to promote stabilization of waste, many passive gas vents were installed as well as leachate collection vaults. This study aimed to evaluate the distribution and movement of leachate in the landfill by ...

Laboratory studies were conducted to investigate scrap-tire-shreds as a potential alternative to conventional gravel in the drainage layer of leachate collection system at the base of landfill. Performance of various physico-chemical characteristics of leachate after passing it through combined bed of scrap-tire-shreds and gravel for different combinations of thickness of scrap-tireshreds and g...

Abstract This work aims to identify the best treatment condition for removal of chemical oxigen demand (COD) and increase biodegradability in an advanced oxidative process photocatalytic ozonation with titanium dioxide (TiO2), applied remediation leachate produced at municipal landfill Campo Mourao, Parana. The experiment was carried out using a chamber system based on corona effect. A statisti...
