We know that the progress of society is accompanied by the improvement of environmental awareness, and the application of geomembrane in mining and landfill sites is more and more extensive. As an important impermeable material, geomembrane can effectively prevent the diffusion of pollutants and protect the environment from damage.
Geomembrane is a kind of polymer synthetic material with excellent impermeability and chemical stability. In the mining industry, geomembrane is used for anti-seepage treatment of tailings ponds, effectively reducing the impact of harmful substances such as heavy metals on the surrounding environment. According to environmental experts, "Mine geomembrane not only improves the safety of tailings ponds, but also reduces the risk of environmental pollution."
Similarly, in landfills, geomembranes also play a vital role. It can effectively isolate the contact between garbage and soil, and avoid the leakage of leachate to pollute groundwater. A study on a large landfill site in China shows that the infiltration rate of leachate is reduced by more than 90% after using geomembrane as the impervious layer.
In addition, the geomembrane also has the advantages of simple construction and low cost. In practical engineering, the laying of geomembrane is faster than other impermeable materials, and the maintenance cost is low. According to the EPA, since the 1980s, operating costs at landfills have dropped by an average of 25 percent due to the adoption of geomembranes.
