  2. Leachate - Wikipedia

    en.wikipedia.org/wiki/Leachate

    A number of complex organic contaminants have also been detected in landfill leachates. Samples from raw and treated landfill leachate yielded 58 complex organic contaminants including 2-OH-benzothiazole in 84% of the samples and perfluorooctanoic acid in 68%. Bisphenol A, valsartan and 2-OH-benzothiazole had the highest average concentrations ...

    en.wikipedia.org/wiki/Landfill_gas

    A gas flare produced by a landfill in Lake County, Ohio. Landfill gas is a mix of different gases created by the action of microorganisms within a landfill as they decompose organic waste, including for example, food waste and paper waste. Landfill gas is approximately forty to sixty percent methane, with the remainder being mostly carbon dioxide.

    Landfills are the primary method of waste disposal in many parts of the world, including United States and Canada.Bioreactor landfills are expected to reduce the amount of and costs associated with management of leachate, to increase the rate of production of methane (natural gas) for commercial purposes and reduce the amount of land required for land-fills.

    Once a landfill site is full, it is sealed off to prevent precipitation ingress and new leachate formation. However, liners must have a lifespan, be it several hundred years or more. Eventually, any landfill liner could leak, [7] so the ground around landfills must be tested for leachate to prevent pollutants from contaminating groundwater.

  9. Landfill gas utilization - Wikipedia

    en.wikipedia.org/wiki/Landfill_Gas_Utilization

    Methane has a global warming potential of 25 [2] times more effective of a greenhouse gas than carbon dioxide on a 100-year time horizon. It is estimated that more than 10% of all global anthropogenic methane emissions are from landfills. [21] Landfill gas projects help aid in the reduction of methane emissions.
