Landfill Gas Bio-oxidation in Passive Biofilters
In this article we discuss landfill gas bio-oxidation (also referred to by many people as the development of the landfill gas biofilter). We also suggest practical methods for avoiding greenhouse gas emissions at closed landfills. This is generally LFG from landfilled waste which is usually 15 years old or older. As time passes, both the […]
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 […]
Landfill Gas Production Rate Quick Calculation Method
The Ready Reckoner or Rule of Thumb Estimate of Landfill Gas Production Rate/Yield! Quickly gain a VERY rough estimate of a landfill’s Landfill Gas Production Rate! For the first considerations of a potential landfill gas production rate, before carrying out a full yield evaluation, for landfill gas utilization projects, you can use the following rules (but […]
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 […]
