LANDFILL GAS Meaning and
Definition
-
Landfill gas refers to the mixture of gases that are formed as a byproduct of the decomposition of organic waste materials in landfills. It is generated by the anaerobic (without oxygen) decomposition process which occurs in the landfill environment as bacteria break down the organic waste.
The composition of landfill gas varies, but it mainly consists of methane (CH4) and carbon dioxide (CO2), with small amounts of other gases such as nitrogen (N2), oxygen (O2), hydrogen sulfide (H2S), and volatile organic compounds (VOCs). The methane content is particularly significant, as it is a potent greenhouse gas that has approximately 25 times the global warming potential of carbon dioxide over a 100-year period.
Landfill gas is typically collected using a network of wells and pipes installed within the landfill. The gas is then extracted and can be utilized in various ways. Commonly, it is flared off to prevent the release of methane into the atmosphere, reducing its impact as a greenhouse gas. Alternatively, landfill gas can be captured and used as a source of renewable energy through processes such as electricity generation or conversion to fuel, heat, or steam.
Efficient management of landfill gas is crucial for minimizing environmental impacts and harnessing its energy potential. In addition to reducing greenhouse gas emissions and promoting sustainable energy practices, the collection and utilization of landfill gas also helps prevent the migration of harmful gases into surrounding areas, reduces odors, and improves overall air quality.

Etymology of LANDFILL GAS
The word "landfill gas" is a compound formed by combining the terms "landfill" and "gas".
The term "landfill" originated from the Old English word "landfyll" which meant the act of filling up land. This was a combination of "land" (referring to an area of ground or soil) and "fyllan" (meaning to fill or stuff).
The word "gas" comes from the Greek word "khaos" meaning "void" or "empty space". Over time, it evolved to "gast", referring to any substance that expands freely to fill a space, particularly in a gaseous state.
So, "landfill gas" refers to gases generated by the decomposition of organic waste in a landfill. The term emphasizes both the context of waste disposal in a landfill and the gaseous nature of the substances produced.
