  • 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/ ...

  • 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 ...

  • 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 ...

  • Use of biocatalysts to reduce hydrogen sulfide emissions from lagoons and landfills

    Emission of odors from ponds and lagoons occurs due to aerobic and anaerobic decomposition of organic solids to release hydrogen sulfide, ammonia, and other organic by-products.  Aerobic biodegradation occurs near the water-air interface, where diffusion of oxygen occurs, while anaerobic degradation prevails mainly near the bottom of the pond or lagoon, where there is low or no dissolved oxygen ...

  • Recycling Vs. Landfills and Incinerators – Do Benefits of One Outweigh the Other?

    Believing the 2011 survey results of the U.S Environmental Protection Agency (EPA), the American nationals generate more than 240 million tons of waste every year. Often referred to as Municipal Solid Waste, this waste originates from households, schools, hospitals, and business establishments. This trash material often finds its place in the wasteland, where it is either recycled, trapped in a ...
