HDPE is chemically resistant, able to withstand the highly corrosive liquid found within leachate. This means it's often found as an underlayment or seperator within a sectioned, sanitary landfill. This prevents leachate from escaping the closed environment, and protects the nearby soil and water from contamination.
HDPE is commonly used in waste or toxic chemical disposal methods, thanks to it's impressive ability to withstand abrasive or corrosive elements. Sanitary landfills use HDPE to control leachate, which is the collected moisture formed by the breakdown of biological waste.
