The waste management industry learnt by hard experience from landfill gas explosions the risks imposed by the generation of landfill gas in their landfills, and the penalties in terms of death and injury when the first landfill gas explosions occurred. Somehow, although the parallel experiences to landfill gas explosions were there from the start in the mining industry, for the […]
Health Effects of Landfill and Landfill Gas The context for the “Emissions and Health Impacts Associated with Waste Management” report, is a UK Government Strategy Unit Report commissioned to assess health effect of landfill (if any was found to exist) from Enviros Consulting. This report was prepared at the request of the Strategy Unit at the UK Cabinet […]
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 greenhouse gas and what does not. […]
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. […]
