  • Turning a Liability into an Asset: A Landfill Gas-to-Energy Project Development Handbook

    Each person in the United States generates about 4.5 pounds of solid waste per day almost one ton per year. Most of this waste is deposited in municipal solid waste landfills. As this landfilled waste decomposes (a process that may take 30 years or more), it produces landfill gas. Landfill gas contributes to the formation of smog and poses an explosion hazard if uncontrolled. Furthermore, because ...


  • 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 ...

  • Europe’s objective: recycle more waste and send less to landfills

    Is waste a problem or a resource? Waste is both, depending on what we do with it. It is a problem because it can affect people’s health and the environment. For example, landfills are an important source of methane emissions, which is a powerful greenhouse gas contributing to climate change. Run off from landfills can contaminate ground waters and soil, which can then enter the food ...

  • Assessing the Impacts of the Iran Nuclear Deal on Climate Change

    Introduction On July 14, 2015, the international economic boycott levied against Iran was scheduled to conclude. In concert with the European Union and the P5+1, the Islamic Republic agreed to a Joint Comprehensive Plan of Action (JCPOA) whereby its capacity for nuclear development would be dramatically curtailed. Among other requirements, Iran is mandated, for a period of 15 years, to ...

  • Learning from Diapers – Life Cycle Assessment as an Investment Risk Mitigation Tool

    Remember the garbage barge? Back in 1987, the Mobro 4000, a barge carrying more than 3,000 tons of garbage from Islip, Long Island, famously departed from New York harbor bound for a landfill site in North Carolina because Islip’s own landfill site was nearly full. The aim was to use the garbage as part of a landfill gas project to generate clean energy. But the barge wasn’t ...

  • Environmental impacts of ocean-energy systems: a life-cycle assessment

    Ocean-energy technologies — which harvest renewable energy from the sea — will have a significant role to play in a future low-carbon society. A recent life-cycle analysis of different ocean-energy devices has found that life-cycle environmental impacts are caused mainly by the materials used in the mooring, foundations and structures. Improving the efficiency and lifespan of the ...

  • Gas analysers support management of Swindon fire

    The capability to convene a multi-agency Air Quality Cell (AQC) was established in England in 2009 following the Buncefield Oil Storage Depot incident. A review of this event identified the need to rapidly co-ordinate the acquisition, analysis and interpretation of air quality data in major incidents. Arrangements have been made in England to bring together experts from the Environment Agency ...

  • Stop trashing the climate

    In June, the Institute for Local Self-Reliance (ILSR) joined with Eco-Cycle and the Global Anti-Incinerator Alliance (GAIA) to release Stop Trashing the Climate, a report documenting the link between climate change and unsustainable patterns of consumption and wasting. Authored by Brenda Platt of ILSR, with coauthors Eric Lombardi of Eco-Cycle (Boulder, Colorado) and Dave Ciplet of GAIA, the ...

  • Is it better to burn or bury waste for clean electricity generation?

    The use of municipal solid waste (MSW) to generate electricity through landfill-gas-to-energy (LFGTE) and waste-to-energy (WTE)projectsrepresentsroughly14%ofU.S.nonhydrorenewable electricity generation. Although various aspects of LFGTE and WTE have been analyzed in the literature, this paper is the first to present a comprehensive set of life-cycle emission factors per unit of electricity ...

  • GTA waste-to-energy?

    While the City of Toronto will utilize its GreenLane Landfill Facility near London, Ontario to manage residual waste in the years to come, neighboring Durham Region (just east of the city) is potentially going in a different direction. Like Toronto, Durham plans to divert up to 70 per cent of waste from disposal, but intends to build a waste-to-energy (WTE) plant, rather than use landfill. On May ...

  • Questions and answers on the Commission Communication `Towards a Circular Economy` and the Waste Targets Review

    What is a circular economy? A circular economy preserves the value added in products for as long as possible and virtually eliminates waste. It retains the resources within the economy when a product has reached the end of its life, so that they remain in productive use and create further value. It may involve: Increasing the time products deliver their service before ...

  • Composting - Best bang for MSW management buck

    For many years, life cycle analyses of end-of-life management practices have been available for all of the basic recyclables as well as organics. The life cycle data, usually derived by the US Environmental Protection Agency's Waste Reduction Model (WARM), represents the net greenhouse gas impact of recycling, landfilling or incinerating a variety of material streams. The model calculates ...

  • Latest analytical technology ensures biogas efficiency

    Anaerobic Digestion (AD) relies on the ability of specific micro-organisms to convert organic material into a gas that can be used to generate electricity. However, these bacteria require specific conditions if they are to function effectively and instrumentation specialist company HACH LANGE has developed a range of online, portable and laboratory instruments that have enabled a large number of ...


  • EPA isues GHG BACT guidance

    Beginning in 2011, major sources of greenhouse gas (GHG) emissions that trigger Prevention of Significant Deterioration (PSD) permitting must implement Best Available Control Technology (BACT) for GHG emissions from new and modified sources. EPA has issued a variety of guidance in an attempt to clarify the BACT determination process for GHG emissions from common stationary sources:1 EPA’s ...
