What landfills can be used for gas recovery and how is energy generated from landfill gas?
The feasibility of installing a landfill gas recovery system depends on factors such as landfill gas generation rates, the availability of users, and the potential environmental impacts. Many different landfill types with varying gas production rates and composition can support energy recovery projects. There are, however, several guidelines to consider when assessing the feasibility of generating energy from landfill gas. The box on the following page lists some of these guidelines. If feasible, energy recovery can be implemented by use of combustion- or noncombustion- based technologies. Combustion-based technologies that recover energy include boilers, process heaters, gas turbines, and internal combustion engines. For example, landfill gas can be piped to a nearby industry, commercial business, school or government building where it is combusted in a boiler to provide steam for an industrial process or heat for a building. It may be combusted in an industrial process heater to prov
