Artesian landfill liner system: numerical and cost optimization models for preliminary design

Sanitary landfilling is the solid waste disposal technique most widely practiced today. In conventional landfill design, the leachate generated in the landfill is contained by a low conductivity liner constructed at the base of the landfill. However, due to the inherent limitations of natural materials and the inevitable imperfections of installing plastic or rubber liners, escape of leachate is inevitable in conventional landfills. The concept …
