When organic waste decomposes in landfills it produces landfill gas—mainly methane and carbon dioxide—which escapes into the atmosphere and drives climate change; the gas also contains volatile organic compounds, hydrogen sulfide and other toxics that cause odors and health risks. Open burning or landfill fires release particulate matter, carbon monoxide, dioxins, furans and heavy metals that worsen air quality and harm respiratory and cardiovascular health. Dust and emissions from heavy equipment further add to local air pollution, and uncontrolled gas migration can expose nearby communities to these pollutants.
