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.
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 […]
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 Power Plant that Use Landfill Gas [Case Studies]
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 […]

Landfill Gas Collection Systems Defined – UK Facts and Myths
Go no further to read all about landfill gas collection systems. LFG collection systems are defined in the next section, followed by a UK landfill gas collection history. Those are the facts, now for the myths! If you scroll further down on this page we explain some myths about Landfill Gas Collection Systems, and a truth. […]
Landfill Gas Engine Tendering Tips for High Landfill Gas Utilisation and Value
We decided to create this article about landfill gas engine tendering due to concerns about lowest cost tendering rules. Read-on for our tips designed to help you procure high landfill Gas Utilisation and low prices. Very often a landfill gas CHP unit (gas engine) is selected which offers a low capital cost, but the purchaser […]
Welcome to Our Website!
Read this first to find out about this website is about. Our aim is to provide those involved in the renewable energy, resource and waste management industries the best source of information about: “Landfill gas, its creation and use, from the processes that produce it, to the production of sustainable renewable energy from it”. We […]
Landfill Gas Bio-oxidation in Passive Biofilters
In this article we discuss landfill gas bio-oxidation (also referred to by many people as the development of the landfill gas biofilter). We also suggest practical methods for avoiding greenhouse gas emissions at closed landfills. This is generally LFG from landfilled waste which is usually 15 years old or older. As time passes, both the […]
