Patent ID: 8672586

Claim:
A method of temperature control and heat exchange of a waste mass comprising: routing at least one heat extraction well throughout the waste mass; channeling a closed-loop fluid circulation pipe into the at least one heat extraction well, the at least one heat extraction well intermittently filled with a highly conductive granular backfill for providing a thermal encasing for said closed-loop fluid circulation pipe; circulating a first circulation fluid throughout the closed-loop fluid circulation pipe via a circulation pump operatively coupled to the closed-loop circulation pipe: and exchanging heat between the first circulation fluid and a second circulation fluid via a heat exchanger having an inlet and outlet for the first circulation fluid and an inlet and outlet for the second circulation fluid and is fluidly coupled to the closed-loop fluid circulation pipe at the inlet and outlet for the first circulation fluid, wherein the waste mass has a first, second, third, and fourth life cycle stage of biochemical processes, the step of exchanging heat between the first circulation fluid and the second circulation fluid further comprises transferring a first level of thermal energy from the second circulation fluid to the first circulation fluid at the first life cycle stage of biochemical processes; extracting a second level of thermal energy from the first circulation fluid to the second fluid at the second life cycle stage of biochemical processes; transferring a third level of thermal energy from the second circulation fluid to the first circulation fluid at a third life cycle stage of biochemical processes; and extracting a constant fourth level of thermal energy from the first circulation fluid to the second fluid at the fourth life cycle stage of biochemical processes.
