  • Reduced Emissions for Landfill Gas Installations

    The use of landfill gas as a source of renewable energy is increasing. For environmental and safety reasons, the owners of the waste storage sites have to strictly monitor and control the construction, operations, and emissions generated. Sulzer offers solutions to control these emissions within the limits given by the government. Landfill gas is similar to natural gas, but it is created by ...

  • Seropédica landfill

    The Seropédica landfill is located on the outskirts of Rio de Janeiro. Since the closure of the 130-hectare big Gramacho landfill, Seropédica now receives over 6,000 tons of waste per day. Seropédica is the most modern solid waste treatment center in Brazil and Hofstetter has been awarded the biogas treatment process, as well as the set up of a flaring system at the landfill. ...

  • Southwest landfill case study

    The Problem: A landfill located in Texas was experiencing high concentrations of ammonia in the leachate from their domestic landfill. Compliance standards were becoming more stringent at the same time ammonia and BOD levels in the leachate stream were increasing in concentration. The Solution: After on‐site testing ...

  • Cutting landfill costs - not capabilities

    The garbage business is generally a good indicator of the economy’s strength. And while the bad news is that waste tonnage is down at most landfills, the good news is that there is a bottom. Most of the drop is due to a slumping construction industry, compounded by less consumer buying. But the garbage business—like taxes and death—is relatively constant. Some landfills are ...

  • Closure Options for Impoundments and Landfills

    In Kentucky, a county board votes to shut down a landfill that had long been the source of odor complaints from nearby residents. In Hawaii, residents push a city council to expedite a delayed landfill closure. Outside Beirut, Lebanon, protesters try to block trucks entering a landfill they say should have been closed a week earlier. These events, while certainly newsworthy, obscure the fact 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 Cap Enhancements

    Introduction: The precipitation to the landfill cover is balanced by the combination of following effects: run-off, cumulating in soil, evapotranspiration, and percolation. For a given amount of precipitation, in order to reduce or eliminate percolation, the effects of run-off and/or evapotranspiration need to be enhanced. Water Harvesting Water harvesting uses ...

  • 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 ...

  • CSDU Lapouyade landfill - Case Study

    The CSDU landfill site (Centre de Stockage des Déchets Ultimes) of Lapouvade is operated by SOVAL, a subsidiary of the CGEA ONYX group. The municipal solid waste for the landfill site comes from Bordeaux and the surrounding area. The two Type 3 containers from Jenbacher installed in 2004 use the biogas that is produced by methanogenesis of the rubbish on the landfill. The engines have a ...

  • Formulation of a landfill pollution potential index to compare pollution potential of uncontrolled landfills

    Generally speaking, landfilling is one of the prominent methods of waste disposal around the globe, but some under-developed and developing countries still continue to practice uncontrolled open dumping of waste. These uncontrolled landfills pose a relatively high threat to the various elements of the environment in comparison with the conventional engineered landfills that are used in many ...

  • Halving construction waste to landfill by 2012

    Government and industry have proposed halving the amount of construction,demolition and excavation waste sent tolandfill by 2012 (“1/2W2L”), as a result of waste reduction, reuse and recycling. How might this be achieved and what will the impact be? Policy targetsIn England, the Government’s Waste Strategy and draft Sustainable Construction Strategy both propose the target of 1/2W2L. ...

  • Landfill Capping Systems: An Introduction to Options

    Geomembranes, predominately linear low-density polyethylene (LLDPE), have been used for landfill caps for decades. Waste Management World has noted how,” Generally they have performed extremely well but, not unexpectedly, there have been a few exceptions that have guided us in developing even better systems.” Currently, there are four commonly used options for landfill caps, each with ...
