  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Closures of mine a new challenge for Romania

    AbstractThe mining activity is one of the oldest activity in Romania, dating from the year 100 B.C. The gold and silver ores represented one of the riches of our country. In time the economic content of metals diminuend, and the ore mines become non profitable. Due to this situation the best option of the State was the closure and ecological rehabilitation of the mines.The steps for the ...

  • Questions and answers on the Commission Communication `Towards a Circular Economy` and the Waste Targets Review

    What is a circular economy? A circular economy preserves the value added in products for as long as possible and virtually eliminates waste. It retains the resources within the economy when a product has reached the end of its life, so that they remain in productive use and create further value. It may involve: Increasing the time products deliver their service before ...

  • Mercury Analysis

    Characteristics of Mercury What is Mercury? Mercury is a naturally occurring silver-colored metallic element noted for its occurrence as a liquid at room temperature and toxic to living organisms. This silvery, opaque liquid metal is very dense, yet has a high surface tension that causes it to form tiny perfect spheres in the pores of the rocks it is found in. It is ...
