Abstract
Disclosed is a system for preventing or mitigating elevated temperatures within a landfill. The system comprises at least one water tight heat exchange unit with a lower edge and an upper edge, wherein the placement of the heat exchange unit is at least one of (1) within the waste mass proximate the area of elevated temperature, or (2) within the area of elevated temperature, the at least one heat exchange unit fabricated to resist differential settlement forces within the landfill as well as the elevated temperatures. The system further includes piping configured to discharge a cooling fluid within the heat exchange unit and a heat exchanger for ejecting heat from the cooling fluid and at least one temperature probe configured to measure the temperature of the waste mass. The system utilizes a pump adapted to circulate the cooling fluid within the piping system and to the heat exchange unit.
