Landfill gas (LFG) is generated during the natural process of bacterial decomposition of organic material contained in municipal solid waste (MSW) landfills. A number of factors influence the quantity of gas that a MSW landfill generates and the components of that gas. These factors include, but are not limited to, the types and age of the waste buried in the landfill, the quantity and types of organic compounds in the waste, and the moisture content and temperature of the waste. LFG gas consists of about 50% methane (the primary component of natural gas), about 50% carbon dioxide (CO2), and a small amount of non–methane organic compounds. Methane is generated in landfills and open dumps as waste decomposes under anaerobic (without oxygen) conditions.

According to the USEPA, MSW landfills are the second-largest source of human-related methane emissions in the United States, accounting for approximately 22% of these emissions in 2008. One way of counteracting these emissions is to properly engineer systems to collect and treat landfill gas. This course is intended for civil and environmental engineers who are interested in treatment and disposal of municipal solid waste.
