  • What is energy recovery?

    Processes like incineration and anaerobic digestion not only provide sources of energy, but they also reduce waste volume The term “energy recovery” often is applied only to a narrow number of methods for converting wastes into energy, when in fact it applies to a broad range of technologies used to create heat, electricity, or fuel. Energy recovery gives ...

  • How can lead be so crucial, but also so toxic?

    Why is everyone talking about lead? Not long ago, like so many historic buildings in the UK, a local parish church near to where I live had the lead stolen from its roof.  Sadly, this is not so unusual and all the more distressing in this case, both because it holds special memories as the church where my wife and I were married, and also because the lead was stolen during heavy ...

  • South Texas Landfill − Case Study

    During 2011, four QED Precision Fine Tune Control Valves™ were installed in wells at a south Texas landfill. The following graphs show the composition of the landfill gas and flow data before and after the installation of the Control Valves in Wells 07, 54, 78, and 90. The closest neighboring well on the same trunk line, using a gate valve for flow control, was also chosen for an additional ...

  • New LFG Collection System Utilizes QED’s Revolutionary LFG Measurement and Control Technology - Case Study

    “The main advantage, to me, is the Fine Tune™ Control Valve* that is used on the QED wellhead - it’s one of those revolutionary things in the landfill gas industry. Gate valves don’t give you very good control unless you always want the valve 100% open and you can apply as much vacuum as possible. But when it comes to low-flow wells then it’s important to be able to ...

  • AutoPumps Manage Landfill Leachate to Keep Methane Flowing - Case Study

    Green Bay adds Gas-to-Energy Facility to 30-year-old Landfil Brown County East Landfill in Green Bay, Wisconsin recently completed a feasibility study that determined it would be economically sound to convert methane gas into electrical energy by electric generators to the site. Two new Cat 3516A+ engines are projected to come on line in December of this year, housed in a new 30 x 100 ...

  • 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 ...

  • Landfill pumps for Gas well dewatering - Case Study

    AutoPumps Keep the Power On for Thousands of Florida Homes Waste Management's Springhill Regional Landfill near Campbellton, Florida generates "green" energy by extracting and burning the methane in landfill gas.

  • Reduced Emissions for Landfill Gas Installations

    The use of landfill gas as a source of renewable energy is increasing. For environmental and safety reasons, the owners of the waste storage sites have to strictly monitor and control the construction, operations, and emissions generated. Sulzer offers solutions to control these emissions within the limits given by the government. Landfill gas is similar to natural gas, but it is created by ...

  • 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 ...

The analyser was on its sixth service since manufacture, under ...

  • Major Considerations in Landfill Closure

    Preparing for the closure and long-term care of a municipal solid waste landfill (MSWLF) can be an inordinate undertaking. Whether public or private, all landfills eventually reach the end of their active lifecycle. Before closure, a landfill must meet a series of criteria as determined by Subtitle D of the Resource Conservation and Recovery Act (RCRA). Following closure, those same regulations ...
