Abstract
Landfills are considered the third largest source of methane emissions in the world, it is a risk to the environment being flammable and a polluting gas. Focusing on atmospheric emissions of methane (CH4) from landfills, this study directs efforts to verify CH4 screening methods. Considering as a case study the Jockey Club Controlled Landfill (ACJ), once known as the largest landfill in Latin America. The goal is to prove a relationship between the surface thermographic indicators and methane emission. Two methods of analysis were applied: surface temperature measurement with Thermal Infrared (TIR) and determination of CH4 emissions with a portable gas monitor (GEM-5000). Results provided both important information on the amount of main methane emission points emitted from the ACJ and the correlation between the thermal anomalies with methane emission points in landfills. The study proves a relation between surface temperature and methane emission, allowing a new control tool for methane emissions, environmental remediation and energy use in a landfill area.
