Biological Processes of Landfills
Explore the science behind modern landfills in this educational video series that examines what happens to waste after it leaves our homes, schools, and communities. Learn how landfills are designed, constructed, and managed to protect human health and the environment. Viewers will also learn how landfill gases, such as methane, are produced and collected; how engineers manage leachate to protect groundwater; and how they monitor landfills to ensure long-term safety.
