  • Landfill gas explosive for global warming

    In response to EPA’s 1991 landfill rules that pushed the industry to larger facilities, landfill operator’s today pile and compact trash on the ground into giant mounds in the shape of a four sided pyramid. As originally contemplated, these mounds of trash were encased in liners to keep the wastes dry so contaminants would not be mobilized to leak into groundwater, along with ...


  • 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 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 ...

  • Recycling Vs. Landfills and Incinerators – Do Benefits of One Outweigh the Other?

    Believing the 2011 survey results of the U.S Environmental Protection Agency (EPA), the American nationals generate more than 240 million tons of waste every year. Often referred to as Municipal Solid Waste, this waste originates from households, schools, hospitals, and business establishments. This trash material often finds its place in the wasteland, where it is either recycled, trapped in a ...

  • Gas Detection and Monitoring Systems

    In greenhouse applications, the accurate measurement of a number of environmental parameters such as carbon dioxide concentration, temperature, light intensity, water, humidity, pH and nutrient levels using sophisticated sensors is used to create a controlled environment for optimising plant growth rates while minimising energy usage. Carbon dioxide concentration is also one of the best ...

  • EPA studies identify techniques for critical leak testing prior to soil-vapor sampling

    Researchers at EPA’s National Risk Management Research Laboratory (NRMRL) in Ada, OK, are developing quality assurance (QA) measures for soil-gas and sub-slab sampling methods that help differentiate contaminant vapors due to vapor intrusion from background sources. Recent research focused on measures to identify leakage of ambient air into conventional vapor probes, which can significantly ...

  • Questions and answers about oil and gas wastewater spills

    Nearly 3 million gallons of briny water generated by crude oil production has leaked from a North Dakota pipeline and reached two creeks, making it the biggest spill of this type of wastewater since the state's Bakken formation oil boom began in 2006. Here are some questions and answers about oil and gas saltwater spills: Q: What does this liquid consist of, and where does it come from? A: ...

  • Greenstars portable monitoring for CHP and flares

    Greenstar’s award-winning KTK landfill site in Kilcullen, Co. Kildare, is unusual in Ireland in that it has three gas engines feeding electricity to the grid and two flares. In Ireland, while flaring is common, engines are not. The flares are run in tandem with engines so that if an engine is ramped down for repair or service, the flare ramps up automatically. All are supplied by 122 ...

  • Is it better to burn or bury waste for clean electricity generation?

    The use of municipal solid waste (MSW) to generate electricity through landfill-gas-to-energy (LFGTE) and waste-to-energy (WTE)projectsrepresentsroughly14%ofU.S.nonhydrorenewable electricity generation. Although various aspects of LFGTE and WTE have been analyzed in the literature, this paper is the first to present a comprehensive set of life-cycle emission factors per unit of electricity ...

  • Talking Trash: The world`s waste management problem

    Trash is a pervasive but unnoticed part of our lives. The great irony of waste management is that even the most efficient and well-run waste collection programs remain out of sight, ignored by the public that they serve. Only with failure does the omnipresence of trash really come to light. Today, many nations face a looming waste management crisis, as their landfills reach capacity and continue ...

  • Easy payback from biogas monitoring

    There is a strong business case for biogas monitoring and CHP protection. A fixed biogas analyser may cost some £6-10,000 and monitor gas every few minutes day and night. By comparison it can save its own cost many times over by protecting CHP engines from expensive unplanned downtime, biogas engine ...
