  • Utilisation of Methane to Generate Electricity: BHP Appin and Tower Collieries

    Background BHP Collieries Division operates five underground coal mines in and around the Illawarra region of NSW. They include the Appin and Tower mines which are situated north-west of Wollongong and some 75 kilometres from Sydney. These two mines produce around 3.5 million tonnes of coal per year which is primarily used for domestic steel making. Some coking and energy coal is also ...


  • Concurrent bioremediation of perchlorate and 1,1,1-trichloroethane in an emulsified oil barrier

    Abstract A detailed field pilot test was conducted to evaluate the use of edible oil emulsions for enhanced in situ biodegradation of perchlorate and chlorinated solvents in groundwater. Edible oil substrate (EOS®) was injected into a line of ten direct push injection wells over a 2-day period to form a 15-m-long biologically active permeable reactive barrier (bio-barrier). Field ...

  • The impact of potential climate policy on the coal bed methane investment in China - a real option–based study

    In this paper, based on the real option theory, the impact of the potential climate policy on the coal bed methane (CBM) investment in China is assessed from the perspective of CBM investment under the uncertainties of future climate policy and CBM market price. The threshold values of the market and policy variables to promote CBM project investment are obtained. Firstly, incorporating the ...

  • Laser gas detector systems for greenhouse gas emissions monitoring

    Two types of portable laser based gas detector for measuring emissions of the greenhouse gases carbon dioxide (CO2) and methane (CH4) from oil and gas operations are described. A scanning open path detector was developed within a Cooperative Research and Development Agreement (CRADA) with the USEPA. This system scans multiple paths across an area source in rapid succession, enabling calculation ...

  • Landfill gas to fleet fuel in Ohio

    In mid-September, the Solid Waste Authority of Columbus, Ohio (SWACO) cut the ribbon on Phase I of its Green Energy Center that will convert landfill gas to compressed natural gas (CNG) for use in CNG-powered cars and medium duty trucks. The facility will produce enough CNG annually to replace almost 250,000 gallons of gasoline, plus additional natural gas sufficient to generate electricity for ...

  • Case study - Upgrading highly loaded waste ponds to “Bio-Gas Banks”

    Problem: Un-covered anaerobic systems can generate significant amounts of odors and renewable energy in the form of methane. The sulfides and methane are lost to the atmosphere due to lack of an impermeable barrier. If the basins were covered, the biogas could be captured, burned and converted to electricity and odors contained. A Missouri project, believed to be the largest and most ...

  • 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 ...


  • Agricultural trade liberalisation and the global environment: evaluating the linkages

    A reduction of trade barriers will influence the overall scale of agricultural activities, the structure of agricultural production, the mix of inputs and outputs, the production technology, and the regulatory framework. These adjustments, in turn, will influence environmental quality by increasing or reducing environmental harm and creating or destroying environmental amenities. International ...
