  • 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 ...

  • Wind-driven SVE system extracts VOCs from landfill

    An innovative soil vapor extraction (SVE) system has operated at the former Ferdula Landfill site in Frankfort, NY, for the past 10 years. The system relies on wind-driven vacuum processes rather than electrically powered air blowers to extract volatile organic compounds (VOCs) from the landfill. After a two-year trial beginning in 1998, the New York State Department of Environmental Conservation ...

  • Landfill Gas Use Trends In The United States

    MOST PEOPLE think of landfills as a necessary evil at best, but our current primary method of waste management generates a by-product with significant energy value - landfill gas (LFG). Collection and control of LFG results in significant reductions in greenhouse gas (GHG) emissions. With the greater focus on climate change, a burgeoning market for GHG emission offsets is emerging and landfills ...

  • 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 ...

  • Application of gas chromatography-mass spectrometry preceded by solvent extraction to determine volatile fatty acids in wastewater of municipal, animal farm and landfill origin

    This study describes extraction of selected volatile fatty acids (VFAs) (containing from 2 up to 8 carbon atoms) with methyl-tert-butyl ether (MTBE) from polluted aqueous samples followed by separation, identification and quantification by gas chromatography coupled with mass spectrometry (GC-MS). Extraction parameters such as time and number of extractions, volume ratio, effect of acidification ...

  • The landfill gas collection, utilisation and surplus gas combustion acting in unison

    In landfill gas utilisation the basic task of the control system is to harmonise three completely independent processes. On the one hand, there is the gas production of the landfill which is inconstant. (From a price point of view, hardly worthwhile to store the gas in a gasometer) On the other side the independent gas utilisation process, which orientates itself to the requirement of the ...

  • Contracting a methane gas extraction system: Engineering and installing extraction wells requires expertise Here’s what these specialty contractors do

    Of the three typical ways of removing methane from landfills — venting, burning, and extraction — only the latter properly disposes of the potentially hazardous gas and offers the option of selling it as fuel. Over the last two decades, 594 U.S. gas-to-energy ...

  • Landfill Gas Model and use of MP5 by Fehily Timoney & Company

    Arthurstown Landfill is located in Kill, Co. Kildare and is Ireland’s largest municipal solid waste disposal facility with a total area of 72 hectares (180 acres). The site uses MP5 for the management of its environmental data which includes gas management, weighbridge information, SCADA leachate management and treatment, performance of flares and gas generation engines. Fehily Timoney ...

  • Raffen landfill site, Cork, Ireland

    AFS were awarded a contract to design a gas and leachate collection system, and carry out a 10-week gas pumping trial to evaluate the levels of gas being generated from Raffen Landfill Site. From the pumping trial data, a 200m3/hr HT flare was designed, built and installed. A hydrovane compressor/receiver/dryer package was installed to operate ten pneumatic leachate extraction pumps. Within ...

  • 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 ...

  • Derryclure landfill phase 2 capping - case study

    Lining Technology have successfully been awarded the contract for the Derryclure Landfill Phase 2 Capping project by Offaly County Council. The contract is for the supply and installation of a 4 layered geosynthetic capping system over the phase 2 capping area (38,000m2). Other works to be completed as part of the contract include the installation of gas extraction and drainage pipework and ...

  • Compost as a landfill cover material for the elimination of methane emissions

    Landfills, with about 40 - 60 Mio t emitted CH4 each year, are considered to be an important global source of the greenhouse gas methane. These emissions are especially caused by inadequate gas collection systems and uncontrolled emissions from old dumps and unauthorised open dumping. With traditional gas collection systems only 40 to 60 % of the produced gas can be collected and reused or safely ...

  • Case study - Geotech’s first GA5000 landfill gas analyser takes 100,000 readings for SUEZ environnement

    Geotech’s first GA5000 analyser, manufactured three years ago, was recently spotted in the company’s calibration rig.  This portable landfill gas monitor was the first production unit of the newly launched GA5000 gas analyser range and has prompted Geotech to look into the analyser’s life since then. The analyser was on its sixth service since manufacture, under ...
