NASA Warms Up to Maryland's Trash

Gas Purification Process - Most of the landfill gas purification process involves removing water. This animation shows four major steps to purifying the landfill gas for Goddard. First, placed throughout the landfill purification plant, filters sift out tiny trash particles and water. Second, a compressor squeezes out more water. Third, pipes cool gas drooling out even more water. Finally, the gas is reheated and transported to Goddard. Warm gas reduces moisture.
