  • Landfill waste gas abatement - Case study

    For over 43 years Catalytic Products International has designed and manufactured specialized oxidation systems for use in controlling process-related VOC emissions. The QUADRANT-NRV Series Thermal Oxidation System is designed for use with the low-volume/high-BTU waste gas stream emitted from many landfill gas purification processes. As we utilize our Venturi Burner Package to process the waste ...

  • 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 ...

  • Mitigating methane emissions from passive landfill vents: a viable option for older closed landfills

    This study investigated the use of biofilters to reduce methane emissions from landfill passive gas vents. Two biofilter designs were evaluated. The two filter designs achieved similar percent oxidation averages. The radial biofilter design, however, obtained a much higher methane oxidation rate. The higher surface area of flow in the radial biofilters decreased the methane influx leading to ...

  • Measurements of Methane Emissions and Surface Methane Oxidation at Landfills: WR1125

    Methane emissions from landfill were estimated to account for around 3% of the UK‟s total greenhouse gas emissions in 2009. The reported figure for methane emissions from landfill in the UK represents 41.5% of all UK methane emissions. The IPCC guidelines indicate that measurement of methane emissions is necessary to validate models and to provide confidence in country specific model ...

  • Use of biocatalysts to reduce hydrogen sulfide emissions from lagoons and landfills

    Emission of odors from ponds and lagoons occurs due to aerobic and anaerobic decomposition of organic solids to release hydrogen sulfide, ammonia, and other organic by-products.  Aerobic biodegradation occurs near the water-air interface, where diffusion of oxygen occurs, while anaerobic degradation prevails mainly near the bottom of the pond or lagoon, where there is low or no dissolved oxygen ...

  • Utilisation of Municipal Solid Waste Compost as landfill cover soil for reducing greenhouse gas emission

    Municipal Solid Waste Compost (MSW-C) was introduced for improving landfill cover soil properties and enhancing methane oxidation. The landfill cover soil was irrigated with leachate for maintaining appropriate moisture content for methane oxidation reaction. It was found that MSW-C was an effective landfill cover material for landfill gas emission control exhibiting the highest Methane Oxidation ...

  • Can phytocapping technique reduce methane emission from municipal landfills?

    Landfill gases, predominantly methane and carbon dioxide, are produced by the biodegradation of organic wastes. Biodegradation occur, if the water comes in contact with the buried waste. Techniques such as clay capping are used to minimise percolation of water into the landfill, or gas collection system installed to reduce methane emission into the atmosphere. The use of clay cap has proven not ...

  • 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 ...

  • Risk assessment of gaseous emissions from municipal solid waste landfill: case study Rafah landfill, Palestine

    This article describes the risk assessment of gaseous emissions from the municipal solid waste at Rafah landfill, Palestine. In this study, Gas-Sim model was used to quantify the gaseous emissions from the landfill and the Land-Gem model was used to verify the results. Risk assessment of both carcinogens and non-carcinogens were performed. Two scenarios were conducted namely with plant uptake ...

  • Feasibility of landfill gas as a liquefied natural gas fuel source for refuse trucks

    The purpose of this paper is to develop a methodology to evaluate the feasibility of using landfill gas (LFG) as a liquefied natural gas (LNG) fuel source for heavy-duty refuse trucks operating on landfills. Using LFG as a vehicle fuel can make the landfills more self-sustaining, reduce their dependence on fossil fuels, and reduce emissions and greenhouse gases. Acrion Technologies Inc. in ...

  • Case study: Lachute landfill

    Substrate: Landfill Biogas flow: 6.500 Nm3/h H2S inlet: 1.300 ppm H2S outlet: 10 ppm Year of installation: 2011 This BioGascleaner was installed as a replacement of another H2S filter which collapsed due to the normal H2S and biogas flow fluctuations of the plant. The system is produced ...

  • 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 ...

  • 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 ...

  • Portable laser gas detector systems for landfill CH4 and CO2 monitoring

    There has recently been a marked increase in interest in detecting and quantifying emissions of the greenhouse gases (GHG) carbon dioxide (CO2) and methane (CH4) from landfills in North America and Europe. The primary drivers for this increased interest are: new and pending legislation requires demonstrated reductions in GHG emissions; permits to expand existing facilities require more accurate ...

  • Turning a Liability into an Asset: A Landfill Gas-to-Energy Project Development Handbook

    Each person in the United States generates about 4.5 pounds of solid waste per day almost one ton per year. Most of this waste is deposited in municipal solid waste landfills. As this landfilled waste decomposes (a process that may take 30 years or more), it produces landfill gas. Landfill gas contributes to the formation of smog and poses an explosion hazard if uncontrolled. Furthermore, because ...


  • Formulating LandGem model for estimation of landfill gas under Indian scenario

    Mostly in India, solid waste without any segregation is deposited into open dumping sites. Through these sites, there is uncontrolled emission of methane and landfill gas. The landfill gas has tremendous potential in terms of converting and using them as source of fuel. The emission of landfill gas depends on types of wastes, its rate of biodegradability, its methane potential, level of ...

  • Long-term leachate emissions from municipal solid waste landfills sre unknown

    The Swiss have always been highly environmentally aware, and for a long while have looked after their environment in an exemplary fashion. The 'Guidelines to waste management in Switzerland' ( EKA, 1986 ) were set in 1986, well ahead of many states. One necessary objective of this as a code of good practice has been that all waste management procedures have to provide materials which either are ...
