  2. Mechanical biological treatment - Wikipedia

    en.wikipedia.org/wiki/Mechanical_biological...

    A mechanical biological treatment (MBT) system is a type of waste processing facility that combines a sorting facility with a form of biological treatment such as composting or anaerobic digestion. MBT plants are designed to process mixed household waste as well as commercial and industrial wastes .

  3. Loci Controls - Wikipedia

    en.wikipedia.org/wiki/Loci_Controls

    LoCI's system is designed to increase methane gas extraction from landfills. The software and hardware provide remote monitoring and control, versus historical practices, which require twice-monthly on-site monitoring and manual adjustments to extract the methane.

  4. Landfill gas utilization - Wikipedia

    en.wikipedia.org/wiki/Landfill_Gas_Utilization

    The use of landfill gas is considered a green fuel source because it offsets the use of environmentally damaging fuels such as oil or natural gas, destroys the heat-trapping gas methane, and the gas is generated by deposits of waste that are already in place. 450 of the 2,300 landfills in the United States have operational landfill gas ...

  5. Landfill gas monitoring - Wikipedia

    en.wikipedia.org/wiki/Landfill_gas_monitoring

    Monitoring of the landfill gas itself can be used diagnostically. When there is concern regarding the possibility of an ongoing subsurface oxidation event, or landfill fire, the presence in the landfill gas of compounds that are more stable at the high temperatures of such an event (above 500 °C) can be evidence for such a process occurring.

  6. Landfill gas - Wikipedia

    en.wikipedia.org/wiki/Landfill_gas

    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 .

  7. Bioreactor landfill - Wikipedia

    en.wikipedia.org/wiki/Bioreactor_landfill

    The increased moisture content of bioreactor landfill may reduce the structural stability of the landfill by increasing the pore water pressure within the waste mass. [15] Since the target of bioreactor landfills is to maintain a high moisture content, gas collection systems can be affected by the increased moisture content of the waste.

  8. Landfill - Wikipedia

    en.wikipedia.org/wiki/Landfill

    Its uses range from simple flaring to the landfill gas utilization and generation of electricity. Landfill gas monitoring alerts workers to the presence of a build-up of gases to a harmful level. In some countries, landfill gas recovery is extensive; in the United States, for example, more than 850 landfills have active landfill gas recovery ...

  9. Resource recovery - Wikipedia

    en.wikipedia.org/wiki/Resource_recovery

    Resource recovery can be enabled by changes in government policy and regulation, circular economy infrastructure such as improved 'binfrastructure' to promote source separation and waste collection, reuse and recycling, [5] innovative circular business models, [6] and valuing materials and products in terms of their economic but also their social and environmental costs and benefits.
