Landfill gas management compound

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

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

Hazards of landfill gas

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 […]

Siloxane and Landfill Gas

Siloxane and landfill gas

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 […]

Potential Impacts of Landfill Gas Emissions

Hazards of landfill gas

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 US Landfill Gas Resources Present an Opportunity for Green Investment

landfill-gas-EPA-outreach

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 […]

Understanding Landfill Gas Risks Before Buying Property Near a Landfill

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.  […]
