The international energy agency (IEA) has stated that the global energy consumption by the industrial sector has grown by 61% compared to the levels recorded in the 60s. The increased energy consumption has implied a considerable increase in the levels of C0 2 present in the atmosphere, bringing to global attention the problem of global warming. In this world context, the industrial sector is called to improve the efficiency of its production cycles, in order to reduce emissions that are harmful to humans and the environment. One way is to exploit the energy that is dissipated in the environment, through waste heat recovery systems.
