  • Landfill Liners Vary by Application

    It was in 1991 that the Environmental Protection Agency promulgated its Criteria for Municipal Waste Landfills that set location restrictions, design and operating standards, groundwater monitoring requirements, corrective actions, closure requirements, and more for landfills. It was these rules that mandated that landfills be lined on the sides and bottom before waste is deposited and capped on ...

  • The use of kaolinite/zeolite mixtures for landfill liners

    The use of kaolinite/zeolite mixtures as alternative landfill materials has been studied. The ratios of kaolinite/zeolite used were K/Z = 0.1, K/Z = 0.2 and K/Z = 0.3. To determine the geotechnical and physicochemical properties of the mixtures, their optimum moisture content, which provides the best compression out in the field, was determined by a compaction test. Also, tests for unconfined ...

  • Locating Geomembrane Liner Leaks under Waste in a Landfill

    Abstract An Electrical Leak Imaging and Monitoring (ELIM SM) survey was used to locate leaks under 2.5 meters of stabilized waste in an active geomembrane-Iined landfill. The landfill is lined with two 2-mm thick HDPE geomembranes that are separated by a geonet drainage layer. The primary liner is covered with 600 mm of drainage sand and 2.5 meters of stabilized waste for a total cover ...

  • Locating Leaks in Geomembrane Liners of Landfills Covered With a Protective Soil

    ABSTRACT The electrical leak location method was used to locate leaks in the geomembrane liners of single-lined and double-lined landfills covered with a protective soil cover. The landfills ranged in size from 0.40 hectare (one-acre) to 3.2 hectares (eight-acre). Water in the leak detection system under the primary liner indicated the primary liners were leaking. The principal of ...

  • The Basics of Slope Stability Analysis for Geosynthetics

    Slope stability analysis is vital to preventing slope failures in a variety of engineering applications including landfill design, roads, dams and embankments, to name a few. Proper analysis anticipates both natural and manmade slopes and failure of foundations and retaining walls. This blog covers the necessity of slope stability analysis, how to conduct the analysis and the role of ...

  • Evaluation of geomembrane, amended soil and composite liner system as lining materials for chromium decontamination in landfill site

    A comprehensive laboratory and field–scale study was performed to explore the efficacies of geomembrane, amended soil liner material and composite liner packs for using as containment liner systems for attenuating chromium transport emanating from a chrome laden solid waste disposal site. Soil samples were collected from the site and were admixed with different amended materials, such as rice ...

  • Empire landfill, Taylor, Pennsylvania

    Empire Landfill in Taylor, PA is situated on a 600-acre site, with 203 acres currently under permit for waste disposal. In anticipant of current and future environmental concerns, the management of Empire Landfill, Inc. has ensured that the landfill exceeds today’s design and operational guidelines. Empire Landfill features double-lined cells, with a “geosynthetic sandwich” of geotextile, two ...

  • Cutting landfill costs - not capabilities

    The garbage business is generally a good indicator of the economy’s strength. And while the bad news is that waste tonnage is down at most landfills, the good news is that there is a bottom. Most of the drop is due to a slumping construction industry, compounded by less consumer buying. But the garbage business—like taxes and death—is relatively constant. Some landfills are ...

  • Major Considerations in Landfill Closure

    Preparing for the closure and long-term care of a municipal solid waste landfill (MSWLF) can be an inordinate undertaking. Whether public or private, all landfills eventually reach the end of their active lifecycle. Before closure, a landfill must meet a series of criteria as determined by Subtitle D of the Resource Conservation and Recovery Act (RCRA). Following closure, those same regulations ...

  • Solar energy landfill caps

    Things weren’t going well at the Erewhon Landfill. It was time to close the facility, and there was no soil left onsite for construction of the cap. Erewhon was a County facility, and the money available for 30 years of post-closure gas monitoring, groundwater sampling and reporting, erosion repairs and maintenance of a grass cover was sorely needed elsewhere. The landfill manager recalled ...

  • KTK landfill capping - geosynthetic lining

    Landfill capping works are currently ongoing at KTK Landfill, Kilcullen, Co. Kildare to complete the final capping works at the facility. The capping area of the project is approximately 93,000m2 with Lining Technology providing lining crews and an excavator for the supply and installation of both smooth and double textured LLDPE liner. Works also involved sealing around existing gas wells and ...

  • Landfill gas explosive for global warming

    In response to EPA’s 1991 landfill rules that pushed the industry to larger facilities, landfill operator’s today pile and compact trash on the ground into giant mounds in the shape of a four sided pyramid. As originally contemplated, these mounds of trash were encased in liners to keep the wastes dry so contaminants would not be mobilized to leak into groundwater, along with ...


  • Landfill Capping Systems: An Introduction to Options

    Geomembranes, predominately linear low-density polyethylene (LLDPE), have been used for landfill caps for decades. Waste Management World has noted how,” Generally they have performed extremely well but, not unexpectedly, there have been a few exceptions that have guided us in developing even better systems.” Currently, there are four commonly used options for landfill caps, each with ...

  • Ontario Landfill Site - Case Study

    A Texas based company with waste management sites around North America have installed electrical generation plants at various locations that use methane collected from the waste. The daily operation of these sites include the management of the leachate, a liquid waste by-product of decomposition, and the collection of gas for electricity production. This is typically carried out at multiple wells ...

  • Pollution level detection in dump clay liners by hyperspectral imaging

    Landfill is the most common and cost–effective method of waste disposal, with collection and transportation accounting for 75% of the total cost. A key point in waste disposal is the picking up and the drainage of percolation fluids to limit the risk of groundwater contamination. Aim of this study was to evaluate the possibility to develop fast and reliable methods to perform an in situ ...
