What happens to the natural gases collected from a sanitary landfill?

Natural gases collected from a sanitary landfill, primarily composed of methane and carbon dioxide, are typically captured through a system of wells and pipes. These gases can be used as a renewable energy source, often generated into electricity or processed into natural gas for heating and cooking. Additionally, capturing landfill gases helps mitigate greenhouse gas emissions, reducing their impact on climate change. If not utilized, these gases may be flared to prevent them from escaping into the atmosphere.
