Methane Gas Facts and Basic Processes Of Waste Decomposition
Methane Gas Facts 1. Methane comprises about 50% of landfill gas, and is the most reduced organic molecule. In other words, no further conversions to simpler organic molecules are possible once methane has been produced. It is produced as an end product of anaerobic metabolism. For the first of our Methane Gas Facts, let us look at […]
Why Landfill Gas Recovery is Important
The Importance of Landfill Gas Recovery in Reducing Greenhouse Gas Emissions and the Proportion of Active Landfill Gas Recovery Achievable Over the Life of a Modern Sanitary Landfill Due to its high content of methane, landfill gas recovery can be regarded on the one hand as a useful alternative source of energy, when collected and […]
Landfill Gas Emissions and Health Effect of Landfill
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 […]
Methane Flux Boxes for Monitoring Landfill Gas Cap Emissions
Methane flux boxes are a tool used to detect the flow (leakage) of landfill gas (methane) through landfill gas restoration capping layers. The UK Environment Agency may require that the landfill gas methane emissions from a landfill restoration cap are monitored regularly. This is required so that areas where excess gas might be escaping, can […]
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, […]
