  • Estimating national landfill methane emissions

    This paper estimates national methane emissions from solid waste disposal sites in Panama over the time period 1990–2020 using both the 2006 Intergovernmental Panel on Climate Change (IPCC) Waste Model spreadsheet and the default emissions estimate approach presented in the 1996 IPCC Good Practice Guidelines. The IPCC Waste Model has the ability to calculate emissions from a variety of solid ...

  • Actively aerated methanobiofilters to control methane emissions from landfills

    Methane (CH4) capture at sanitary landfills for energy recovery is capable of reducing the impact of CH4 on the global atmospheric carbon budget. However, gas capture may only be viable where gas quantities are high enough to warrant economical energy production. Considering the potential global warming impacts, there is a need to ...

  • In-situ estimation of the methane generation rate for a wet and highly organic solid waste landfill

    Significant investments in landfill gas utilisation projects are required at project commencement. The methane generation rate for the Villa Dominico Landfill in Buenos Aires, Argentina is 0.26 yr−1, a very high rate as a result of the high organic content in the waste, and high moisture conditions within the refuse. The implications for landfills is that ...

  • Landfills Expand Energy Output

    HIGH fossil fuel prices and growing concern about global climate change are creating favorable conditions for landfill gas energy (LFGE) projects. Notably, endorsement of LFGE by Federal agencies and many states as a form of “green” power has enabled LFGE developers to earn premiums for electricity marketed through green power programs, and to benefit from expanded federal tax credits for ...

  • 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 ...

  • Energy recovery from biogas purification

    Energy recovery from biogas is becoming more common, but the processes are hampered with the presence of hydrogen sulfide (H2S). Biogas is a mixture of methane and carbon dioxide (CO2) and is often contaminated with toxic quantities of H2S. Sources of biogas are: municipal landfills that produce landfill gas (LFG), wastewater treatment plants, industrial plants, and large scale livestock farms. ...

  • Low Pressure Separation Membrane: Purification Of Landfill Gas

    Summary: The paper is presenting preliminary results of the on-site trial of the gas purification pilot plant based on membrane separation technology, operating at relatively low pressure- This trial is an initial phase of a bigger project aiming at production of clean and high calorific value gas that could be used as a substitute of fossil fuel. e.g. for powering vehicles. The objectives of the ...

  • Formulating LandGem model for estimation of landfill gas under Indian scenario

    Mostly in India, solid waste without any segregation is deposited into open dumping sites. Through these sites, there is uncontrolled emission of methane and landfill gas. The landfill gas has tremendous potential in terms of converting and using them as source of fuel. The emission of landfill gas depends on types of wastes, its rate of biodegradability, its methane potential, level of ...

  • 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 ...

  • Case study - QED pumps are the pumps of choice at North America’s largest landfill

    The Puente Hills Landfill in Los Angeles County, California, is the largest operating landfill in North America based on daily tonnage received.  Located in an unincorporated area of Los Angeles County near Whittier, California, it is owned and operated by the Sanitation Districts of Los Angeles County.  It has received approximately 118 million tons of solid waste as of April 2008, ...

  • Europe’s objective: recycle more waste and send less to landfills

    Is waste a problem or a resource? Waste is both, depending on what we do with it. It is a problem because it can affect people’s health and the environment. For example, landfills are an important source of methane emissions, which is a powerful greenhouse gas contributing to climate change. Run off from landfills can contaminate ground waters and soil, which can then enter the food ...

  • Energy Recovery from Residual Waste by Means of Anaerobic Digestion Technologies

    ABSTRACT Anaerobic digestion (AD) is a natural process, spontaneously taking place in natural surroundings, such as marshes,bogs, paddies, or in cesspits, landfills, and dedicated digesters, used for the conversion of organic waste into a rich gas. Typical AD substrates are: manure, sewage sludge, high BOD wastewater, and – more recently - the organic fraction of Municipal Solid Waste (MSW), ...

  • Estimates of CO2 emissions reduction and potential power generation from biogas at Mare Chicose landfill

    In this study, the annual generation of Landfill Gas (LFG) and methane using the Scholl-Canyon model have been predicted for 1998-2030 for five scenarios of landfill management at the Mare Chicose landfill in Mauritius. Using the Approved Large-Scale Methodology AM003 and Approved Baseline Methodology AM0010 of the Approved Methodologies for CDM activities, the carbon dioxide (CO2) emissions ...

  • Composting generates cash for greenhouse gas benefits

    Chicago Climate Exchange (CCX) recently finalized an initiative to develop a protocol for issuing offsets to projects that avoid greenhouse gas (GHG) emissions through composting or other similar approaches. This article explores the development of the new protocol, reviews its key attributes and describes how an entity can earn tradable credits for its GHG mitigation project. In 1992, the U.S. ...

  • Municipal solid waste - waste to energy conversion in India: an overview

    Municipal solid waste (MSW) is generated in enormous quantities, in India, causing environmental problems. It is collected primarily by sweeping in India and dumped on the outskirts of urban areas, which pollute the environment. Such MSWs also release methane and carbon dioxide, which are important greenhouse gases. MSW comprises biodegradable material. The MSW disposal methods in India mainly ...
