  • Measuring and interpreting gas flow from landfill boreholes case study

    Current landfill gas measurement practice for measuring the gas composition is well understood, and there are standard procedures and instruments available to analyse the gas. It is also current recognised practice to measure the gas 'flow' from boreholes to monitor the production of gas in a landfill site. If care is taken to make the measurement in the same way each time, changes in the ...

  • 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 ...

  • First commissioned LFG power generation unit in Iran

    The first landfill gas (LFG) power generation station in Iran was officially commissioned in July 2009. This plant is located in old landfill site of Mashhad, the second largest city in Iran. This landfill has been receiving municipal solid wastes (MSW) since 1975 but the first activity for biogas extraction in this site was started in 2000. The LFG extraction system in this site is based on ...


  • Carbon offsets from organic waste conversion projects

    The Climate Act ion Reserve (the Reserve) has long had a protocol to give credit for the capture and destruction of methane emissions from organic waste in landfills, but they have now opened up the possibility of credits for projects that prevent that waste from entering landfills in the first place. In October 2009, the Reserve adopted the Organic Waste Digestion Project Protocol, covering both ...

  • Designing A Better Alternative for Post-Closure Care

    After a landfill has reached the end of its service phase, federal law requires owners to install a final soil cover and maintain it over the next 30 years. This is the traditional strategy that most landfill owners employ and represents a significant cost of business. When all the layers are tallied together, the capping and post-closure period can cost up to $400,000 for a small, 100-acre ...

  • 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 ...

  • Biotreatment of Odors from the Zimpro Sludge Conditioning Process

    Management of odor emissions generated during thermal sludge conditioning is a well known disadvantage of the “Zimpro” process. Traditional methods of using chemical oxidation and high temperature destruction result in the formation of secondary products, such as chlorine gas, organic halocarbons or nitrogen oxides. In this study, biotrickling filter technology was evaluated at the Villa Hills ...

  • Heat Pump Used to Drain Contaminated Sludge in a Steel Factory

    Summary In 1987, new regulations required that factories dispose of their contaminated water and waste themselves. Making galvanised steel wire, the Stelfil factory produces sludge contaminated with lead and zinc. Stelfil spent thousands of dollars to bury this waste and evaluated three systems to remove most of the water: a gas dryer, an induction heated screw conveyor and a heat pump system. ...


  • State of the environment industry

    The current economic downturn has exacted a heavy toll on many industry sectors. The collapse of the banking and finance system, the humbling failures of the big three North American automakers, and slowdowns in construction and housing market spending have prompted massive injections of government cash to keep the wheels of commerce turning - however slowly. In the US the Associated Builders and ...
