In Europe, a large-scale landfill renovation project is underway. In order to prevent pollution of surrounding soil and groundwater caused by leachate from garbage, a large number of geomembranes were used for anti-seepage treatment in this project. These geomembranes come from well-known local manufacturers in Europe, and their product quality and performance have undergone strict testing and certification. The project team also adopted the method of stacking multiple layers of geomembranes to further improve the anti-seepage effect. The implementation of this project not only effectively solves the environmental pollution problem of landfills, but also promotes the application and development of the European geomembrane industry in the field of environmental protection.
