Landfill Gas Management
Landfill Gas Management is an important necessity at most landfills receiving degradable wastes such as MSW and many non-hazardous industrial wastes. It is necessary to extract landfill gas in order to prevent it from migrating away from the landfill.
Landfill gas (LFG), a mixture of methane and carbon dioxide, has the potential to cause harm to human health, via explosion or asphyxiation, and to cause environmental damage such as crop failure. It also has a significant climate changing effect in the world’s atmosphere.
Examples of all three have occurred both within and outside landfills and are discussed here.
Landfill Gas Management is applying good practice techniques for extracting and controlling LFG. All are are now reasonably well established and in common use, and are discussed in this category.

Why Do Landfill Gas Monitoring in Soil, the Air, Near the Surface, & In Confined Spaces
Landfill gas monitoring is critical for preventing health risks and hazards near landfill sites. Detecting gases like methane, which is flammable and a climate change contributor, is essential. Effective monitoring employs soil, air, and emissions techniques to ensure safety and environmental protection…
Landfill Methane Capture: Advancing U.S. Emissions Reduction Through Technology and Policy
Harnessing Landfill Methane: Progress and Challenges in U.S. Emissions Reduction Efforts The management of landfill-derived methane represents one of the most significant opportunities in America’s climate strategy. As a potent greenhouse gas with 28-36 times the warming potential of carbon dioxide over a 100-year period, methane demands urgent attention from policymakers, waste management professionals, and […]
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 […]
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 […]
