Michael Caldwell, director of groundwater and technical programs at Waste Management, and his team have been examining two potential reasons to pump liquid from a landfill. One is core pressure reduction and slope stability. Another is heat removal.
During a Global Waste Management Symposium (GWMS) 2020 session on elevated temperature landfills (ETLF), Caldwell explained that pumping of liquids for heat (enthalpy) removal can help mitigate heat buildup in a landfill.
