  • Landfill leachate treatment

    Landfills are categorized by regulations in three types: industrial, municipal, and hazardous. Individual landfills may be further differentiated by the types of waste which they accept. All landfills are required to be capped, usually occurring at the end of each day. The cap is typically 6-8” of soil. The cap reduces odor and loss due to wind. At the closing of the landfill, a permanent ...

  • Landfill Leachate Sources and Treatment Options

    What is leachate? In a lab, it is any liquid that extracts solids as it passes through matter. In a landfill, it is the water that enters the facility in a number of ways, passes through waste material on contact, contains a wide range of constituents, and must be addressed with a proper operations plan. Leachate treatment options and mitigation are one of the greatest costs for landfill ...

  • Utilisation of landfill gas for the generation of energy

    The gases in landfill sites that develop during degradation processes, largely contribute to the greenhouse effect and additionally harbour considerable safety and health hazards. However, they are also often rich in methane and therefore a potential energy carrier. In many countries much of this potential for the generation of electricity and heat from landfill gas still exists. Furthermore, ...

  • Combined Landfill Gas and Leachate Extraction Systems

    There is currently a shift of emphasis in the approach to treatment of landfill gas and leachate. Until recently, there have been two disparate schools of thought concerning the collection and disposal of these two by-products of organic waste degradation within the same bio-reactor. The tendency in the past has been to study gas and leachate as separate problems each of which requiring a ...

  • Why high temperature combustion of landfill gas?

    Due to the accumulation of knowledge and the tightening of environmental law, the landfill technology has increasingly become concerned with the management of trace compounds in landfill gas. With landfill gas, contamination is through sulphur, chlorine, fluorine, halogenated hydrocarbons and heavy metals. Other trace elements such as volatile organic compounds (VOC), impose environmental ...

  • Landfills Expand Energy Output

    HIGH fossil fuel prices and growing concern about global climate change are creating favorable conditions for landfill gas energy (LFGE) projects. Notably, endorsement of LFGE by Federal agencies and many states as a form of “green” power has enabled LFGE developers to earn premiums for electricity marketed through green power programs, and to benefit from expanded federal tax credits for ...

  • Effects of landfill leachate treatment on hepatopancreas of Armadillidium vulgare (Crustacea, Isopoda)

    The major environmental impact to the landfill is emission of pollutants via the leachate and gas pathway.The hepatopancreas of the terrestrial isopod Armadillidium vulgare (Isopoda, Crustacea, Latreille 1804) takes an important role in bioaccumulation of contaminants, such as heavy metals. To evaluate the effects of landfill leachate treatment, two different approaches are here applied: 1) ...

  • Landfill remediation with refrigerants and chlorinated solvents

    PROJECT DESCRIPTION Between 1979 and 1980, industrial and hazardous wastes were disposed of at the Site in a series of unlined pits, each of which was used for a particular type of waste disposal. It is reported based on evaluations of manifests that approximately 3.4 million gallons of hazardous liquid wastes and between 3,700 and 4,100 tons of solid wastes were disposed of in the pits ...

  • “New” Bioreactor Landfill Technology is 20 Years Old

    Municipal solid waste landfills have gradually evolved to engineered, anaerobic, dry-tomb facilities designed to protect the environment. They present, however, long-term liabilities that require decades of care. Aerobic bioreactor technology achieves rapid stabilization of waste and offers many advantages over conventional sites, including the elimination of methane, a major greenhouse gas. The ...
