The Explosive Limits for Methane Biogas Explained
Q: What is meant by the “explosive limits” for methane? A: Explosive Range and Flammability – A gas that will burn is said to be “flammable.” Any flammable gas can explode under certain conditions. The range within which an explosion can occur is known as the explosive limits for methane. In order for a flammable gas to explode, […]
Carbon Trading in the EU Emissions Trading Scheme
Frequently Asked Questions in Carbon Trading How does the EU Emissions Trading Scheme (the “EU ETS” – also referred to as CCTS, and CDM) affect the Waste Industry? First of all – both hazardous and municipal waste incinerators will not be subject to the scheme. However, the burning of landfill gas (either on its own […]
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 […]
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 […]
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 […]
