Sustainability in Food Production: Cumulative Energy Demand for Separation Processes
Abstract
In order to achieve the aim of sustainability in industrial processes a minimization of the cumulative energy demand is required with the boundary condition of highly closed material cycles. The cumulative energy demand has to be determined for the whole process chain, the auxiliary materials and the production facilities. In industrial processes the energy demand for separation processes plays a key role. Recently, several new separation processes have been suggested for the food industry and in particular membrane processes. The existing studies of the energy demand are, however, not fully satisfying. No determination of the cumulative energy demand has been performed and the modelling of the basic process is frequently too simple. Hence, in the present project, the cumulative energy demand of two separation tasks shall be determined under the boundary condition of highly closed material cycles. The tasks concern the separation of xylitol from gluconic acid and the desalination of whey. For both tasks the alternative methods electrodialysis and ion exchange shall be studied by sufficiently deep modelling. The aim of the project is a further development of sustainabily analysis with respect to food technological processes and to suggest optimised processes for the separation of xylitol from gluconic acid and for the desalination of whey.
