Market Development of HDPE Geomembrane in Landfill

In recent years, with the generation of a large amount of solid waste such as production waste, domestic waste, commercial waste and tourist waste, landfills have gradually become one of the final disposal methods of urban waste. The landfill is to lay solid waste in a thin layer of a certain thickness on a site with good anti-seepage performance, which is mechanically compacted, and then covered with soil for disinfection. In this process, a large amount of geosynthetic materials will be used. Then, in the field of sanitary landfill, geosynthetics are facing huge development opportunities.

    At present, the commonly used landfill liner technology methods include vertical water interception sheet pile, vertical water interception geological membrane, bottom sealing technology of rotary jet grouting, underground mud section and so on. The surrounding enclosures in sanitary landfills can be reinforced by means of anti-seepage, water isolation, isolation and reverse filtration, drainage, reinforcement, etc. Prevent landfill leachate from seeping out, guide the leachate to drain away, and recharge it to prevent garbage from sliding and being covered by garbage. HDPE geomembrane plays the main force of materials. As a polymer composite material, HDPE geomembrane has good tensile properties, strong corrosion resistance, high anti-aging properties, excellent physical and chemical properties, and has a service life of more than 50 years. Geomembrane and other geosynthetics are properly deployed according to environmental requirements, and the most reasonable design scheme has been introduced, which has become the most correct practice recognized by the market.

    In terms of future development, referring to the characteristics of sanitary landfills, the development and utilization of geosynthetic materials, the development and application of related monitoring and quality control technologies such as landfill liner leakage detection, etc. The optimization and specification of geosynthetics is also urgent.
