About a decade ago, some waste companies and environmental engineers began noticing a concerning occurrence: liquids were not draining vertically through waste into the floor of the leachate collection system as efficiently. This happened as facilities began receiving more waste types, and it especially caught engineers’ attention when they began noticing elevated temperature landfills, with the latter concern ultimately driving development of more robust liquid collection and removal designs, as there is a correlation between saturated waste masses and elevated temperatures.
