  • 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 ...

  • 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 ...

  • 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 types of technologies for converting LFG into Energy

    A number of factors, including the availability of an energy market, project costs, potential revenue sources, and other technical considerations, can determine which technologies are most appropriate for a particular landfill gas-to-energy (LFGE) project. Technologies for converting LFG into energy include the following. Electricity Generation Approximately 70 percent of the LFGE ...

  • 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 ...

  • Improved well tuning achieved at a Landfill gas to Energy developer`s sites - Case Study

    Building and managing a high-BTU landfill gas to energy system can present many challenges, but it’s not as complicated as it might seem. The key: start with a healthy, consistently productive wellfield. Morrow Renewables, formerly South Tex Renewables, specializes in doing just that. Headquartered in Midland, Texas, they began in the natural gas industry before building a reputation as one ...

  • U.S. EPA Promulgates Final Air Toxics Standards for Compression Ignition Reciprocating Internal Combustion Engines (RICE)

    On March 3, 2010, U.S. EPA promulgated final National Emissions Standards for Hazardous Air Pollutants (NESHAP) for existing compression ignition (CI) stationary Reciprocating Internal Combustion Engines (RICE) that were not previously regulated by the existing, so called, RICE MACT (i.e., 40 CFR Part 63, Subpart ZZZZ).  The RICE MACT rule was originally promulgated in 2004.  The March ...

  • Are incineration and landfills the answer to save us from the recycling crisis?

    For plastic recycling, this year hasn’t exactly been one of the best – what is to blame? Oil. Shockingly, it actually costs more to recycle old plastic than it does to make new in many ways. Petroleum prices have fallen so low, as low as 70% below the level in June 2014. This may be great for some – however with it has fallen the cost of Virgin Plastic which is made from ...

  • Dispersed Phase Inertisation (DPI): A New Technology for the Treatment of Landfill Leachate and Complex Water

    Inertisation is thus far the only technology for the conversion of leachate and contaminated water into an inert product, thereby facilitating handling and disposal in MSW landfills. Introduction One of the most complex aspects of the global management of an MSW landfill or treatment plant is leachate. This liquid comes mainly from the degradation of organic matter, added to other ...

  • Biomethane enters the gas grid article for energy world

    The Carbon Plan, published in 2011, aims to reduce UK carbon emissions by a quarter from 1990 levels. With the current policies in place, the UK is on target to reduce emissions by over a third by 2020 and with the introduction of new technologies this should increase to an 80% reduction by 2050. However, currently around half the UK’s carbon emissions result from heat related processes and ...

  • Digester Developer Taps Natural Gas Markets

    IN the late 1990s, Dan Eastman and two colleagues were researching business opportunities in the renewable energy industry. They were looking for a commercially viable technology that could take renewable energy from an experimental phase to a solid business investment. In 1999, Eastman and his partners founded Microgy, Inc., with its base in Wisconsin. The company licensed the Xergi anaerobic ...

  • Renewable natural gas regional market assessment case study

    In 2010, MJB&A completed a report for a major electric and natural gas utility on the state of the renewable natural gas (“green gas”) markets in the US. For the purposes of the analysis, “green gas” refers to gas that is cleaned, compressed and sold into the pipeline for distribution and use by natural gas customers. The report provided an overview of environmental ...

  • Generation using gas-fuelled engines in South Africa – an overview

    Most gas engines are Otto cycle spark ignition internal combustion reciprocating engines using natural gas as the primary fuel. Smaller models utilise stochiometric combustion while the larger engines are lean burn engines with pre-chamber ignition systems. The engines are coupled with packaged generator sets, ...

  • Identifying Leaks from Natural Gas Pipelines at a Safe Distance

    The use of natural gas, of which methane is the principle component, is increasing worldwide. According to the American Petroleum Institute methane meets 24% of U.S. energy demand and heats over 50% of all U.S. households. It also has many industrial uses, such as the manufacture of chemicals like ammonia, methanol, butane, ethane, propane and acetic acid; it is also an ingredient in products as ...

  • Case study - Pierce County, Washington: home of the first public transit fleet in the country to run on renewable natural gas

    Summary: Li 1986 Pierce Transit was one of the first public transit agencies in the U.S. to trade in its diesel and gasoline-powered buses for buses fueled by compressed natural gas (CNG). 27 years later, this pioneering Agency has just finalized a new contract with the local utility, Puget Sound Energy, to buy an even better fuel: the renewable compressed natural gas (R-CNG). This ...

  • Redwood City Case (In Situ Gas Thermal Remediation + C3 Technology (GTR™+C3))

    The former Dry Cleaner site was located in Redwood City, California, contaminated by tetrachloroethylene (PCE). Affected soils also contained low levels of PCE degradation byproducts, such as trichloroethylene (TCE), and were presumed to have an approximate extent of 384 square feet (16’ x 24’ area) to a depth of 10 feet beneath the building. The remediation goal was driven by vapor ...
