  • Santa Clara converts low concentration landfill gas to clean energy

    Landfills are an excellent source of methane-rich gas that can be used to generate renewable power. Methane is produced at a landfill as trash decomposes and can be used as fuel for a gas generator to produce electricity. Since 1986, the City of Santa Clara had successfully done this, and had been able to export power to a local utility. However, over time, gas production at a closed landfill ...

  • 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, ...

  • Landfill gas to fleet fuel in Ohio

    In mid-September, the Solid Waste Authority of Columbus, Ohio (SWACO) cut the ribbon on Phase I of its Green Energy Center that will convert landfill gas to compressed natural gas (CNG) for use in CNG-powered cars and medium duty trucks. The facility will produce enough CNG annually to replace almost 250,000 gallons of gasoline, plus additional natural gas sufficient to generate electricity for ...

  • The changing picture of greenhouse gas reporting for landfills

    With the implementation of Federal Mandatory Greenhouse Gas (GHG) reporting in 2010, landfill owners can find themselves subject to GHG reporting regulations at the federal level, and in some cases, also at the state or local level. This article will review the Federal Mandatory Reporting Rule (MRR) requirements for municipal solid waste (MSW) landfills subject to mandatory reporting under 40 ...

  • 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 ...

  • 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 ...

  • Solar energy landfill caps

    Things weren’t going well at the Erewhon Landfill. It was time to close the facility, and there was no soil left onsite for construction of the cap. Erewhon was a County facility, and the money available for 30 years of post-closure gas monitoring, groundwater sampling and reporting, erosion repairs and maintenance of a grass cover was sorely needed elsewhere. The landfill manager recalled ...

  • Landfills case study: trash isn’t always dirty

    Most of us don’t put a lot of thought into our trash once it leaves our front door; we may give it a cursory glance as it is hauled away never to be seen again. However, what many of us don’t know is that more and more of our trash—or the byproducts of it, at least—are being used in creative ways to power our daily lives. We never counted on it, but the trash is no longer ...

  • Landfills have a huge greenhouse gas problem. Here’s what we can do about it.

    We take out our trash and feel lighter and cleaner. But at the landfill, the food and yard waste that trash contains is decomposing and releasing methane, a greenhouse gas that’s 28 times more potent than carbon dioxide. Landfill gas also contributes to smog, worsening health problems like asthma. Globally, trash released nearly 800 million metric tons (882 million tons) of ...
