7 reasons why landfills need geomembranes
The main reasons for using geomembranes in landfills are seepage prevention and environmental protection. Here are some specific reasons:
1.Prevent groundwater pollution:
Waste in landfills can produce harmful leachate called leachate or landfill leachate. As an anti-seepage layer, geomembrane can effectively prevent these harmful substances from penetrating into groundwater, thereby preventing groundwater from being polluted.
2.Protect the soil:
Geomembranes prevent leachate from seeping into the ground and contaminating the surrounding soil. This is vital to maintaining the quality of ecosystems and land.
3.To avoid surface water contamination:
Prevent harmful substances in landfills from entering nearby rivers, lakes or other surface water bodies through leachate, thereby protecting the water quality of water bodies.
4.To prevent the spread of leachate:
Geomembranes effectively confine leachate within the confines of the landfill, preventing leachate from spreading to the surrounding environment and causing a wider environmental impact.
5.Comply with regulations and standards:
Regulations and environmental standards in many countries and regions require the use of geomembranes or other anti-seepage materials in landfills to ensure the environmental friendliness and sustainability of the landfill.
6.Extending landfill life:
Geomembrane can effectively slow down the penetration rate of harmful substances in landfills and help extend the service life of landfills. This is important in reducing the need for new landfills and slowing down the consumption of land resources.
7.Improve landfill operation efficiency:
The use of anti-seepage layers can reduce leachate treatment and management costs and improve the efficiency of landfill operations. This includes reducing the resources and equipment required to collect, treat and dispose of leachate.
Overall, the use of geomembrane is an effective technical means that helps minimize the negative impact of landfills on the surrounding environment and is in line with the principles of sustainable development.
