  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Synthetic turf system solves landfill erosion challenge

    After four years as landfill district manager for IESI Corp., Delaney Lewis was discouraged. Although one of the Louisiana landfills for which he was responsible exhibited ideal geology, the soil characteristics were not conducive to side slope maintenance. The soil of the LaSalle/Grant landfill was highly erodible, exhibited a high plasticity index and had a natural pH of 4.0. ...

  • Zero Waste to Landfill Goal: Portland Aluminium

     Portland Aluminium has achieved a significant reduction in the amount of waste going to landfill. Although driven primarily by business needs including the pursuit of efficiencies, waste reduction has been achieved by evaluating processes, gaining the commitment of its workforce and combining these efforts with both cleaner production and waste minimisation concepts. ...


  • 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 ...

  • Evaluation of methane oxidation in a landfill cover material using a simple indicator approach

    Estimates of methane (CH4) oxidation rates (Rg) in biocovers are crucial for development of abatement strategies. Rg values were estimated in a landfill biocover with a simple approach based on gas diffusion theory. R ...

  • Shipping Emissions - The Environmental Case for Sea Water Scrubbing

    The romantic image of a luxury liner cruising blue seas amid blue skies and trailing a plume of smoke is too close to the truth for comfort. The emissions from shipping make an increasingly conspicuous contribution to air quality, health and environmental problems of Europe, and indeed, the world. Yet an effective and safe technology to dramatically reduce these emissions is being discouraged, ...

  • Microturbines, Gas Engines Link Biogas to the Grid

    OPPORTUNITIES to produce electricity from methane are being improved continuously as manufacturers introduce new and upgraded equipment to address market needs and varying characteristics of raw biogas. In the renewable energy from organics recycling arena, the two primary types of electricity generation equipment are microturbines and reciprocating gas engines. This article provides a brief ...

  • Identifying Leaks from Natural Gas Pipelines at a Safe Distance

    The use of natural gas, of which methane is the principle component, is increasing worldwide. According to the American Petroleum Institute methane meets 24% of U.S. energy demand and heats over 50% of all U.S. households. It also has many industrial uses, such as the manufacture of chemicals like ammonia, methanol, butane, ethane, propane and acetic acid; it is also an ingredient in products as ...

  • Sustainable management of household solid waste

    In most countries, the majority of household solid waste is landfilled because of associated low capital, operation and maintenance costs. However, many existing landfills have exhausted their handling capacities and new facilities are faced with the problem of siting. Alternatives to traditional landfill practice are required to achieve sustainability in managing solid waste. This manuscript ...

  • AutoPumps keep the power on for thousands of Florida Homes - case study

    Waste Management's Springhill Regional Landfill near Campbellton, Florida generates 'green' energy by extracting and burning the methane in landfill gas. Its $7 million landfill gas energy (LFGE) plant, with six large Caterpillar engines running 24 hours a day, seven days a week, is capable of producing 4.8 million watts of power. Most of the energy goes to the Alabama Electric Cooperative for ...

  • Measurements and Standards to Support Increased Energy Efficiency and Reduced Environmental Impact

    “The world is facing twin energy-related threats: that of not having adequate and secure supplies of energy at affordable prices and that of environmental harm caused by consuming too much of it.” Daniel Hecker, economist, Bureau of Labor Statistics, July 2005 Buildings in the U.S. consume 72 percent of all electrical energy produced in this country. Emissions associated with ...

  • Environmental Sensors in Waste Management

    Issue: As part of an increasing sentiment among European consumers that environmental protection is important, concern about the impact of landfill is growing. Sensor technology makes it possible to measure and control inputs to landfill sites and pollutants arising from them. However, the exploitation - or uptake - of such technology has been lower than expected in the waste management sector. ...


  • Composting releases less air pollution than previously thought - study

    A new study funded by the California Integrated Waste Board (CIWMB) indicates that well-managed composting of green waste and food waste releases significantly less air pollution than previously thought. The study also demonstrates that a relatively inexpensive management technique - covering active compost piles with a layer of finished compost - may lower air emissions even further, by as ...
