Landfill gas is a by-product of decomposing landfill waste. At high concentrations, landfill gases can release excessive greenhouse gases, cause undesirable odours, and create explosive hazards. For both nearby residents and site workers, immediate health risks include dizziness, headaches, confusion, and asphyxiation due to oxygen displacement.

Monitoring landfill gases is a crucial and ongoing process, extending well beyond a landfill site's closure. This essential practice facilitates:

  • Subsurface insight: Gaining a clear understanding of underground activities.
  • Enhanced waste management efficiency: Optimising operational effectiveness.
  • Regulatory adherence: Ensuring comprehensive compliance with environmental standards.

Throughout a landfill’s lifecycle, gas content and gas concentrations can vary. Consisting predominantly of Methane (CH4) and Carbon Dioxide (CO2), the following gases can also be present at different stages:

Gas content changes throughout the lifecycle of a typical landfill with the different phases is demonstrated in this graph.

The success of landfill gas management programs can be aided by monitoring the gases present at each landfill site, improving outcomes during operation as well as in the years after the operation has ceased. There are three main benefits of measuring and recording the gases produced by landfill waste:

  • The health of the landfill – Measuring concentrations with landfill gas monitoring equipment allows users to monitor the state of decomposition, as well as the health of the gas-generating bacteria. This can prevent subsurface fires and keep the decomposition stable. Continuous monitors such as the GasClam2 Ground Gas Monitor can provide users with long-term unattended measurements and keep users up to date on the health of the landfill.
  • Operational efficiency & resource recovery – By understanding waste decomposition and precisely monitoring gas flows, managers can significantly streamline operations and optimise landfill gas extraction. This proactive approach not only mitigates environmental risks and reduces fugitive emissions, but also enables the efficient capture of methane for conversion into a valuable and sustainable energy source, thereby reducing reliance on fossil fuels.
  • Regulatory compliance – In Australia, landfills are regulated by each state's Environmental Protection Authority (EPA) bodies. The primary objectives of these regulations are to manage potential hazards, adverse environmental impacts, and the potential loss of amenities from landfill gas, dust, and odour during both landfill operation and post-closure. Links to state EPA landfill management information are available below.

How Landfill Gas Can Impact Our Environment

Migration is a process in which gases can move from one site to another due to factors such as pressure differences in the soil and cavities, as well as permeability. When migration occurs, escaping gases can present a hazard to a wider area outside of the landfill site. Landfill gas monitoring equipment, such as the IECEx Certified Geotech GA5000 Portable Landfill and Contaminated Land Gas Analyser, can provide users with important data on gas conditions at landfills. These instruments are ideal for perimeter monitoring, field management, as well as site investigations. The data logged can assist users in meeting regulatory and compliance requirements. The Geotech GA5000 is one of the instruments recommended for Category 1 usage according to the landfill gas fugitive emissions monitoring guideline by EPA Victoria. Category 1 gas analysers are specifically designed for the purpose of monitoring landfill gas, whereas Category 2 gas analysers are low-concentration methane detectors such as the Huberg Laser One. 

Methane Gas Leaks from Closed Cranbourne Landfill Site

Throughout recent history, there have been numerous incidents related to the migration of landfill gases. One of the most prominent in Victoria is the Cranbourne gas leak, which occurred in 2008. During the incident, methane gas leaked from a closed site in Cranbourne, Victoria, with the gases then migrating into a nearby housing estate. As a result, methane built up within homes, with levels reaching explosive concentrations in at least one home, requiring residents to evacuate. Landfill gas management assists in helping to manage these risks before they become an issue.
