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 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 […]

Fugitive Emissions of Methane and Landfill Gas Explained

Featured image for the article on 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 […]

Landfill Gas Power Plants

Landfill Gas Power Plants should be installed at all landfills, where the landfill gas (LFG) extraction rate is large enough to sustain a steady flow for long periods (multiple years). A typical Landfill Gas Power Plant for most landfill sites is an internal combustion engine, or possibly a gas turbine. The typical landfill gas power plant is used […]

Installing a modern Landfill Power Plant is a great way to use Landfill Gas to make renewable energy. Read the following Case Studies and you will learn why. Although in the recent years the UK has improved the way it recycles waste. The UK still has a mountain to climb – quite literally – because most […]

Frequently Asked Questions in Carbon Trading How does the EU Emissions Trading Scheme (the “EU ETS” – also referred to as CCTS, and CDM) affect the Waste Industry? First of all – both hazardous and municipal waste incinerators will not be subject to the scheme. However, the burning of landfill gas (either on its own […]
