NEW ORLEANS — This video shows how a landfill is supposed to collect gases that build up inside the mounds of waste.
Our animated graphic takes you on a 3D tour of the intricate system of pumps and pipes that’s supposed to keep liquids from flooding the bottom of the waste piles. A working landfill allows gases a clear path into collection wells. But if the liquid isn’t properly collected, the gas has nowhere to go but up and into the air.
