Application of HDPE Geomembrane in Waste Management System - Landfill
High-density polyethylene geomembrane is a thin film material produced by a specially formulated high-density polyethylene resin, through a blown film process. The two sides are flat and smooth, the thickness is usually between 0.75mm and 3.0mm, the width can be 1 to 8 meters, and the length is customized according to the engineering design and customer needs. This material not only has good flexibility, has a high permeability coefficient, but also has strong puncture resistance, high impact strength, good heat and cold resistance, excellent chemical stability and excellent weather resistance, anti-aging properties. These characteristics make HDPE geomemofilm can adapt to a variety of different harsh geological and climatic conditions, especially suitable for geological uneven settlement area engineering.

Landfills play a vital role in waste management systems. In order to ensure the effective operation and environmental protection of landfills, high-density polyethylene geomembrane (HDPE geomembrane), as an advanced impermeable material, is widely used in the construction and maintenance of landfills.
In landfills, HDPE geomembranes are mainly used to build impermeable layers to prevent landfill leachate from polluting groundwater. Leachate is the sewage with high concentration of pollutants produced by the inflow of rainwater and surface water and the decomposition of the garbage itself in the landfill process. The composition of this liquid pollutant is complex and it penetrates into the ground quickly, which poses a serious threat to the groundwater environment. With its extremely low permeability coefficient, HDPE geomemofilm can effectively prevent leachate from penetrating into the ground and protect the safety of the groundwater environment.
Applications:
Bottom impermeable layer:
Laying a layer of HDPE geomembrane at the bottom of the landfill to form a complete impermeable barrier, effectively preventing landfill leachate from penetrating into the ground. This layer is the key to the anti-seepage system of landfill, which is directly related to the environmental protection effect of landfill.
Slope impervious layer:
HDPE geomemofilm is laid on the slope of the landfill to prevent the loss of garbage and the leakage of leachate caused by rain erosion. The installation of anti-seepage layer of slope can further enhance the overall stability of landfill and reduce the risk of environmental pollution.
Covering layer:
Covering the surface of the landfill with a layer of HDPE geomembrane can prevent rainwater from directly washing the garbage and reduce the production of leachate. At the same time, the covering layer can also play a role in insulation and moisturizing, and promote the stabilization of garbage. It is of great significance to improve the treatment efficiency of landfill and reduce the operating cost.
