  • 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 ...

  • Why high temperature combustion of landfill gas?

    Due to the accumulation of knowledge and the tightening of environmental law, the landfill technology has increasingly become concerned with the management of trace compounds in landfill gas. With landfill gas, contamination is through sulphur, chlorine, fluorine, halogenated hydrocarbons and heavy metals. Other trace elements such as volatile organic compounds (VOC), impose environmental ...

  • The landfill gas collection, utilisation and surplus gas combustion acting in unison

    In landfill gas utilisation the basic task of the control system is to harmonise three completely independent processes. On the one hand, there is the gas production of the landfill which is inconstant. (From a price point of view, hardly worthwhile to store the gas in a gasometer) On the other side the independent gas utilisation process, which orientates itself to the requirement of the ...

  • Utilisation of landfill gas for the generation of energy

    The gases in landfill sites that develop during degradation processes, largely contribute to the greenhouse effect and additionally harbour considerable safety and health hazards. However, they are also often rich in methane and therefore a potential energy carrier. In many countries much of this potential for the generation of electricity and heat from landfill gas still exists. Furthermore, ...

  • Controlling H2S Emissions from Landfill Gas

    A major US waste handling company operates a large landfill in Florida, and in 1992, when Hurricane Andrew struck southern Florida, the landfill saw a huge increase in the amount of C&D waste. Shortly after this, the levels of H2S started dramatically rising. This company evaluated several technologies for the removal of H2S, which was estimated to be as high as 5000 ppmv, with up to 2-3 tons/ ...

  • Development of Low noise landfill gas flare

    Summary: Increasing requirements of the environmental standards and planning permission conditions create more challenges to the equipment providers. Environment Agency guidance demands low emission levels and local planners put low noise levels in their conditions for landfill sites. Achieving both at the same time with conventional equipment was found problematic. Biogas Technology has ...

  • Landfill Gas Use Trends In The United States

    MOST PEOPLE think of landfills as a necessary evil at best, but our current primary method of waste management generates a by-product with significant energy value - landfill gas (LFG). Collection and control of LFG results in significant reductions in greenhouse gas (GHG) emissions. With the greater focus on climate change, a burgeoning market for GHG emission offsets is emerging and landfills ...

  • 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 ...

  • The reduction of greenhouse gas emissions using various thermal systems in a landfill site

    In this paper, the Greenhouse Gas (GHG) emissions from an uncontrolled landfill site filled with Municipal Solid Waste (MSW) are compared with those from controlled sites in which collected Landfill Gases (LFG) are utilised by various technologies. These technologies include flaring, conventional electricity generation technologies such as Internal Combustion Engine (ICE) and Gas Turbine (GT) and ...

  • 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 ...

  • Landfills types of technologies for converting LFG into Energy

    A number of factors, including the availability of an energy market, project costs, potential revenue sources, and other technical considerations, can determine which technologies are most appropriate for a particular landfill gas-to-energy (LFGE) project. Technologies for converting LFG into energy include the following. Electricity Generation Approximately 70 percent of the LFGE ...

  • Update on Federal Air and GHG Regulations Affecting Landfills

    EPA’s recent regulatory changes are expected to alter the way landfills are regulated for the foreseeable future with a potential to add additional compliance costs for the industry.  The air quality and greenhouse gas (GHG) regulatory framework at the federal level is currently in a state of flux with respect to landfills. The landfill industry awaits the issuance of a revised ...
