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.
Landfill Gas Project Feasibility: How to Assess Whether an LFG Energy Project Will Work
A landfill gas project feasibility study should answer a deceptively simple question: is there enough recoverable landfill gas, of suitable quality and for long enough, to justify investing in a particular use for it? Answering that question properly takes more than entering a waste tonnage into a landfill gas model. You need reliable waste disposal […]
John Zink vs. Zeeco Landfill Gas Flare Systems: Features, Pricing, and Compliance
Choosing between John Zink and Zeeco landfill gas flare systems hinges on performance needs, emissions targets, and site conditions. Understand their offerings — from ultra-low emissions to cost-effective solutions — and ensure your facility’s compliance with EPA NSPS Subpart XXX while optimizing operational costs…
Methane Migration and Landfill Gas Migration: Risks, Pathways, Detection and Control
Methane migration is the movement of methane through soil, rock, made ground and other subsurface pathways away from the place where the gas was generated. At landfill sites, methane forms as a major component of landfill gas and, unless adequately contained and controlled, can migrate laterally beyond the deposited waste. The most serious consequences occur […]
Landfill Gas-to-Electricity vs. Direct Pipeline Injection: ROI and Feasibility Compared
Comparing landfill gas-to-electricity and direct pipeline injection highlights key differences in processing and market applications. With the U.S. having just 16.6% of landfills producing energy, choosing between electricity generation and pipeline injection depends on factors like site size, energy prices, and infrastructure proximity…
Caterpillar vs. Cummins Landfill Gas Engines
When comparing Caterpillar vs. Cummins landfill gas engines, their approach to handling corrosive fuels like siloxanes and hydrogen sulfide stands out. Caterpillar’s G3500 series excels in large-scale, low-BTU applications, while Cummins offers strong mid-range performance with lean-burn technology. Selecting the right engine is crucial for project profitability…
Landfills and Methane Gas – Solutions and Environmental Impact
Methane from landfills is 80 times stronger than CO2 over 20 years, posing a critical climate challenge. The EPA’s 3.7 million metric tons estimate contrasts with satellite data suggesting 6 million tons, underscoring the need for effective methane reduction and landfill management strategies…
Gas Flaring Systems vs. Gas-to-Energy Systems for LFG Utilization and Compliance
Gas flaring meets EPA compliance but incurs costs with no return, while LFG energy recovery systems offer revenue potential. With the EPA’s LMOP tools and carbon credit opportunities, making the right choice is vital for financial and environmental benefits. Discover which system excels in compliance and outcomes…
UK Landfill Gas – Energy, Insights & Information
Beneath capped surfaces of former UK rubbish tips, methane from decomposing waste is powering homes. While landfill gas output is declining due to stricter waste policies, capturing this potent greenhouse gas remains a critical climate win, offering a unique chance to maximize energy recovery from legacy sites…
What Home Water Softeners and Landfill Gas Have in Common: Reducing Environmental Waste
Water softeners and landfill gas are two things you may not think are linked in any way. One is a household plumbing addition, and the other is a natural byproduct of organic waste, such as food scraps and yard trimmings, decomposing in a landfill. However, if these two things are brought together, their similarities are […]
Understanding Landfill Gas Risks Before Buying Property Near a Landfill
Buying Real Estate: Understand Landfill Gas Risks before buying land near a landfill! Landfill sites can produce methane, and that can continue for many years. It has been a known issue for years. Site operators used to see small landfill gas fires as minor problems when they first started to happen in the 1970s in […]
