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.
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 […]
Passive Landfill Gas Biofilter Research Reveals Potential as an Effective and Viable Option
The Landfill Gas Biofilter – Developing Bio-oxidation Filter Technology for Landfill Gas Treatment During the Long Period of Dwindling Gas Yields at Modern Sanitary Landfills (This article is based upon a paper ref: M. Huber-Humer; Dwindling Landfill Gas – Relevance and Aftercare Approaches; 2nd Boku Waste Conference 2007, Institute of Waste Management, BOKU.) The production and […]
Methods of Siloxane Removal from Biogas
There are at least 5 methods of siloxane removal from biogas which have been used. This remarkable range of methods is described below. First, we will define what siloxane is and explain why it needs to be removed: Siloxane removal from biogas is imperative to guarantee a consistent performance of frequently used machinery. Machinery like […]
Landfills or Incineration? Which is Best for Reducing Carbon Emissions
Greenhouse Gas Generation – Landfilling and Incineration Compared So, you want to know which is better for the planet’s greenhouse gas emissions – Landfills or Incineration? When waste is incinerated, two greenhouse gases are produced, carbon dioxide and nitrous oxide. The IPCC has produced detailed guidance on what counts as a greenhouse gas and what does […]
Landfill Gas Management – How Long Will it be Needed?
How Long Will It Take Before a Sanitary Landfill Stops Producing Landfill Gas? Researchers in landfill gas management who have observed landfill gas generation rates in modern sanitary landfills, and how these vary with time, suggest that: Landfill gas generation rates increase very rapidly after the onset of gas generation (known as methanogenesis), in a […]
Landfill Gas Cut-Off Trenches for Landfill Gas Migration Control
Landfill gas cut-off Trenches can be successfully used for landfill gas migration control where landfill gas is escaping from a landfill underground and threatening to enter properties, or causing the die-back of trees and vegetation on the landfill perimeter. Landfill Gas Cut-Off Trenches Landfill Gas Cut-Off Trenches can be a simple, and when designed correctly, […]
Hazards of Landfill Gas And Risks to Building Development
Understanding the hazards of landfill gas and evaluating the risks in relation to the location and form of building development, is fundamental to arriving at a successful and safe design strategy. The major hazards of landfill gas with respect to building development are summarized as follows: (a) Flammabilily hazards of landfill gas Landfill gas is […]
