  2. Landfill gas - Wikipedia

    en.wikipedia.org/wiki/Landfill_gas

    Landfill gases have an influence on climate change. The major components are CO 2 and methane , both of which are greenhouse gases . Methane in the atmosphere is a far more potent greenhouse gas, with each molecule having twenty-five times the effect of a molecule of carbon dioxide.

    Residents can drop off food waste, coffee grounds, paper towels, napkins and other materials at either center to keep them out of the Wake County landfill. To date, the town has collected 80 tons ...

    en.wikipedia.org/wiki/Food_loss_and_waste

    Methane, or CH 4, is the second most prevalent greenhouse gas that is released into the air, also produced by landfills in the U.S. Although methane spends less time in the atmosphere (12 years) than CO 2, it is more efficient at trapping radiation. It is 25 times greater to impact climate change than CO 2 in a 100-year period.

  5. Landfill gas utilization - Wikipedia

    en.wikipedia.org/wiki/Landfill_Gas_Utilization

    It is important not only to control its emission but, where conditions allow, use it to generate energy, thus offsetting the contribution of two major sources of greenhouse gases towards climate change. The number of landfill gas projects, which convert the gas into power, went from 399 in 2005 to 519 in 2009 in the United States, according to ...

    Garbage piling up in landfills isn’t just an eyesore, it’s also a climate nightmare, belching out large amounts of planet-warming gas.

    These projects collect the methane gas and treat it, so it can be used for electricity or upgraded to pipeline-grade gas. (Methane gas has twenty-one times the global warming potential of carbon dioxide). [18] For example, in the U.S., Waste Management uses landfill gas as an energy source at 110 landfill gas-to-energy facilities. This energy ...

    en.wikipedia.org/wiki/Biodegradable_waste

    These trace gases include a large array of species, mainly simple hydrocarbons. [16] Landfill gases have an influence on climate change. The major components are CO 2 and methane, both of which are greenhouse gases. Methane in the atmosphere is a far more potent greenhouse gas, with each molecule having twenty-five times the effect of a ...

  9. Causes of climate change - Wikipedia

    en.wikipedia.org/wiki/Causes_of_climate_change

    As the warming from CO 2 increases, carbon sinks absorb a smaller fraction of total emissions, while the "fast" climate change feedbacks amplify greenhouse gas warming. Thus, both effects are considered to each other out, and the warming from each unit of CO 2 emitted by humans increases temperature in linear proportion to the total amount of ...
