Landfill Gas Use and Origins
Landfill gas use is the collection and treatment of methane or other gaseous substances from the decomposition of waste in a landfill to create power, heat, and energy. In addition to fossil fuels and farming, municipal solid waste (MSW) landfill gas was third in the world as the contributor to methane emissions as a greenhouse […]
Landfill Methane Capture: The Global Warming Reduction “Quick Win” You’ve Never Heard Of
Concerned about the menacing effects of landfill gas on our environment? You’re not alone, but it’s not as bad as it might be where a landfill has a well-engineered Landfill Methane Capture system installed. In fact, we go so far as to say that landfill methane capture and utilisation is the global warming reduction “Quick […]
Fundamentals of Landfill Gas
Understanding the fundamentals of landfill gas is crucial for environmental researchers, waste management professionals, and many others engaged in addressing climate change. A natural byproduct of organic material decomposition in landfills, this flammable gas plays a substantial role in global warming due to its composition. While not odorous if well managed it is closely associated […]
Outcomes of COP26 – Pledges and What the Methane Emissions Target Means for Landfill Gas Companies
There were at least 5 important outcomes of COP26. In this article, we provide a short summary of the pledges which were agreed at the COP26 summit last November in Glasgow, in video and as text. The 26th United Nations (UN) climate change conference of the parties (COP26) took place in Glasgow in November 2021. […]
Siloxane and Landfill Gas
Siloxane and Landfill Gas: The elimination of VOCs and siloxanes is an important aspect of the LFG conditioning process for any vehicle fuel or pipeline injection project. Engines, turbines, and compressors can be damaged by even trace concentrations of siloxanes, thus they must be eliminated. VOCs are a contaminant that would be sufficiently eliminated in […]
UK Landfill Gas Emissions – Stringent EA Controls Implemented
The waste management industry is required to control UK landfill gas emissions to a high standard. The Environment Agency (EA) ensures that all licensed (closed) or permitted landfill sites which contain landfill gas are regulated to ensure that emissions are kept to a minimum. This is enforced either under the pollution prevention and control (PPC) […]
Gases from Landfills
All landfills should use the gases from landfills. This is done by installing gas collection systems to avoid as far as is reasonable the emission of methane. Methane is a strong “greenhouse gas”. It produces more than 20 times the global warming effect of carbon dioxide. “Landfill gas is a complex mix of different gases […]
Landfill Gas Migration Defined and Explained
Landfill gas migration is defined as the process which occurs when the landfill gas generated within a landfill moves from the site of original waste deposition out of the landfilled waste, into the surrounding environment. This may take place as a result of the gas flow induced by the positive gas pressure produced by the […]
Landfill Gas Flares
About three-fourths of currently operational projects in the United States generate electricity from LFG. Electricity for onsite use or sale to the grid can be generated using a variety of technologies, including reciprocating internal combustion engines, turbines, microturbines, and fuel cells. The reciprocating engine is the most commonly used conversion technology for LFG electricity applications […]
Fugitive Emissions of Methane and Landfill Gas Explained
It is well known that fugitive emissions of methane and landfill gas occur when methane escapes from production facilities, wells, pipes, compressors and other equipment associated with coal mining or natural gas extraction, landfills, and biogas plants. It is obviously very important to reduce fugitive emissions to an absolute minimum. Why are Fugitive Escapes of […]
