Today the demand of energy is increasing tremendously, but available energy lacks in supply. Hence, there is no option for proper and efficient utilization and conservation of energy. In this paper the main stress is given on energy conservation by using technique of utilizing waste heat. A review of recovery and utilization of waste energy systems is presented. The thermal treatment of waste with the heat recovery provides us with clean and reliable energy in the form of heat as well as power. This has contributed to primary energy savings in conventional utility systems.
