The invention relates to an improvement of the method for the utilisation of waste heat for the generation of mechanical energy with optional, simultaneous cold production, according to patent application P3101858.0. The method can be used as a downstream process (coupled process) of thermodynamic processes and cyclic processes producing waste heat, the generation of mechanical energy and from this electrical energy being of prime importance and cold production with variable power share being an additional option. The aim of the invention is to improve the utilisation of waste heat according to the main patent whilst an increase of the usable proportion of the waste heat supply results in an efficiency increase in respect of the energy utilisation. According to the invention, this is achieved in that for utilisation of the waste heat a desorption cascade is used in which the waste heat is employed in several stages for the desorption of working substances from enriched solutions. In addition, the hot weak solution is also regeneratively cooled by desorption of working substances. The sphere of application of the invention is in all processes producing waste heat, such as nuclear power plants, chemical plants, drying processes and flue gas generating processes.
