Landfill gas management involves the collection and treatment of gases produced by decomposing waste in landfills. As organic materials break down, they release gases like methane and carbon dioxide, which can be harmful to the environment. Proper management helps reduce greenhouse gas emissions and can even capture methane for energy use. Techniques for landfill gas management include installing gas collection systems and flaring excess gas to convert it into carbon dioxide, which is less harmful. Additionally, some facilities use landfill gas to generate electricity, providing a renewable energy source while minimizing environmental impact.
