Waste heat is the energy associated with the waste streams of air, exhaust gases, and/or liquids that leave the boundaries of a plant or building and enter the environment. It is implicit that these streams eventually mix with the atmospheric air or the groundwater and the energy becomes unavailable as useful energy. The absorption of waste energy by the environment is often termed thermal pollution. Waste heat is that energy which is rejected from a process at a temperature high enough above the ambient temperature to permit the recovery of some fraction of that energy for useful purposes in an economic manner.
