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 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, […]
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 […]
Landfill gas (biogas) released from landfills contains small quantities of siloxane. It can also be found in biogas from sewage treatment plants. A siloxane is any chemical compound composed of elements of the form R2SiO, where R is a hydrogen atom or a hydrocarbon group. They belong to a wide class of compounds known as […]
Landfill gas when emitted from a landfill gives rise to a list of possible impacts. Just think of the following attributes of landfill gas emissions each of which brings the risk of potential impacts of landfill gas emissions: Landfill gas is; flammable, explosive after it is emitted, when in the right mixture with air (oxygen) an asphyiant devoid of […]
Untapped landfill gas resources in the US are surprisingly large due to the fact that a regulatory requirement to collect it has generally been absent. According to the EPA in the US in 2011- 2012 there were about 510 candidate landfills with no landfill gas extraction and utilization (such as Landfill Gas to Electricity (LFGTE)) which […]
Buying Real Estate: Understand Landfill Gas Risks before buying land near a landfill! The ability of landfill sites to evolve methane has been recognised for very many years by site operators who appeared until the mid-seventies to accept small fires caused by ignition of methane as one of the minor problems associated with waste disposal. […]
