Landfill Gas Bio-oxidation in Passive Biofilters

Landfill Gas Bio-oxidation research image

In this article about landfill gas bio-oxidation (also referred to by many people as the development of the landfill gas biofilter) we look at practical methods for avoiding greenhouse gas emissions at closed landfills (from landfilled waste which is usually 15 years old or older) As time passes, both the rate of landfill gas being […]

The Explosive Limits for Methane Biogas Explained

Methane Biogas

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

Passive landfill gas biofilter

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

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: Siloxane Removal from Biogas: Activated Carbon Technique Activated carbon is widely used to remove organic substances from gases and liquids because it has excellent adsorbent properties and a large surface area. A proprietary […]

Methane Gas Facts and Basic Processes Of Waste Decomposition

Methane gas facts

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 […]

Notorious Landfill Gas Explosions During the 1980s in the UK and the US

Landfill gas explosions

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 […]

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

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 […]

What are Carbon Credits?

carbon credits explianed

Carbon credits explained! The carbon credit trading technique is a crucial element of state and global emissions trading schemes to help manage global warming. But, what exactly are Carbon Credits? Now read on: The idea behind using carbon credits is to cap industries at a global scale in the amount of yearly emissions they produce.  […]
