  • Case study - Monitoring landfill gas

    Infrared absorption Infrared absorption is usually the preferred method for measuring methane and carbon dioxide. Most gases absorb radiation in the infrared region. The wavelength of radiation that is absorbed is determined by the natural vibration frequencies of the molecule. These natural frequencies will depend on several factors. Thus different gas molecules have different natural ...

  • 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 ...

  • St. Landry Parish Solid Waste Disposal District: Turning Landfill Gas Into Biofuel

    One of the pioneers in biogas use, St. Landry Parish Solid Waste Disposal District has used its landfill gas to fuel vehicles in their local Sheriff’s Department. Born out of the need to deal with open dumps in the late 1970s, the St Landry Parish Solid Waste Disposal District’s purpose was to deal with the growing problem. Before its creation, waste was collected by a ...

  • Combined Landfill Gas and Leachate Extraction Systems

    There is currently a shift of emphasis in the approach to treatment of landfill gas and leachate. Until recently, there have been two disparate schools of thought concerning the collection and disposal of these two by-products of organic waste degradation within the same bio-reactor. The tendency in the past has been to study gas and leachate as separate problems each of which requiring a ...

  • Greenhouse gas emission potential of the municipal solid waste disposal sites in Thailand

    Open dumping and landfilling are the prevalent solid waste disposal practices in Thailand. Surveys on the disposal sites revealed the presence of 95 landfills and 330 open dumps. Methane emission potential at these sites was estimated by three methods. Results of the Intergovernmental Panel on Climate Change (IPCC) method, Landfill Gas Emission model (LandGEM), and closed flux chamber technique ...

  • Monitoring And Analysis of Landfill Gases

    CoGDEM is the trade association representing manufacturers and service providers who are active in the field of gas detection instrumentation and environmental monitoring apparatus. Crowcon Detection Instruments Ltd was one of the founding members of CoGDEM, and in this article their Product Manager of Fixed Systems, Andy Avenell, gives an update on Landfill Gas. Landfill is by far the most ...

  • Landfill leachate treatment

    Landfills are categorized by regulations in three types: industrial, municipal, and hazardous. Individual landfills may be further differentiated by the types of waste which they accept. All landfills are required to be capped, usually occurring at the end of each day. The cap is typically 6-8” of soil. The cap reduces odor and loss due to wind. At the closing of the landfill, a permanent ...

  • Landfill Gas Model and use of MP5 by Fehily Timoney & Company

    Arthurstown Landfill is located in Kill, Co. Kildare and is Ireland’s largest municipal solid waste disposal facility with a total area of 72 hectares (180 acres). The site uses MP5 for the management of its environmental data which includes gas management, weighbridge information, SCADA leachate management and treatment, performance of flares and gas generation engines. Fehily Timoney ...

  • 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 ...

  • Landfill Leachate Sources and Treatment Options

    What is leachate? In a lab, it is any liquid that extracts solids as it passes through matter. In a landfill, it is the water that enters the facility in a number of ways, passes through waste material on contact, contains a wide range of constituents, and must be addressed with a proper operations plan. Leachate treatment options and mitigation are one of the greatest costs for landfill ...

  • Landfill remediation with refrigerants and chlorinated solvents

    PROJECT DESCRIPTION Between 1979 and 1980, industrial and hazardous wastes were disposed of at the Site in a series of unlined pits, each of which was used for a particular type of waste disposal. It is reported based on evaluations of manifests that approximately 3.4 million gallons of hazardous liquid wastes and between 3,700 and 4,100 tons of solid wastes were disposed of in the pits ...

  • Oxidation System for Sanitary Landfills & Recycling Centers

    The Broward County, Florida, Central Sanitary Landfill & Recycling Center operates the country’s largest landfill gas turbine-to-energy plant. Approximately 9 MMSCFD of landfill gas is collected from 300 wells and converted into electricity. During the cleanup after hurricane Andrew, large amounts of construction and demolition debris were brought into the landfill for disposal. Over a very short ...

  • Modelling methane and vinyl chloride in soil surrounding landfills

    Sanitary landfilling is used in many countries as a preferred method for disposal of household wastes for reasons of simplicity and economics. Immediately following its deposition within a landfill, most of the organic fraction of waste will begin to undergo degradation through chemical and bacterial action. Landfill gas (LFG) is a product of biodegradation and consists of primarily methane ...

  • Economic evaluation of a landfill system with gas recovery for municipal solid waste management: a case study

    Economic activity uses resources, which leads to waste generation. With rapid industrialisation and urbanisation, per capita solid waste generation has increased considerably. Solid waste generation data for last two decades shows an alarming increase. Owing to its improper and untimely collection, the transport and disposal of municipal solid waste poses a severe threat to various components of ...

  • Compost as a landfill cover material for the elimination of methane emissions

    Landfills, with about 40 - 60 Mio t emitted CH4 each year, are considered to be an important global source of the greenhouse gas methane. These emissions are especially caused by inadequate gas collection systems and uncontrolled emissions from old dumps and unauthorised open dumping. With traditional gas collection systems only 40 to 60 % of the produced gas can be collected and reused or safely ...

  • Donzi landfill expansion using stratagrid case study

    Background The Donzi Lane Landfill in Atlanta, GA had been in use since the 1970's for construction and demolition waste disposal. The site was nearing its capacity and additional landfill space was urgently needed due to the accelerating population growth and waste stream generated by development. Due to the high cost and long lead times for designing, permitting and constructing new ...

  • Disposal options for solid waste of Bangalore city based on its characteristics

    A detailed analysis of Bangalore's solid waste has been done to suggest various management options for safe disposal. It has been observed that Bangalore's solid waste contains a larger proportion of degradable waste compared to many other cities. Based on detailed analysis of available data, it has been suggested that a landfill with a leachate and gas collection system is better than an inert ...
