Abstract
Social demand for developing new composite liner system is recently expanding larger to protect human health from landfill environmental problems caused by any leachate of harmful matters from waste deposits.
A colloid-pressurized system was proposed as the central component of composite barrier liners to make waste landfill of high quality in sound waterproof and prompt recovery system. We have developed a self-recovery system, which consists of geomembrane, geocomposite and colloidal liquid. The recovery test was carried out in the laboratory to investigate a governing factor required for a clay liner. The effect of saturated soil by salt water and new product of geotextile on quality of a waste landfill was also checked. Further we confirmed the automatically recovery system through a life-size test.
