The problem of managing and recycling electrical appliances at the end of their life cycle often leads to huge energy waste. For the optimal management and minimization of the ecological footprint, it is necessary to study the targeted obsolescence of electrical appliances and to plan the reuse, maintenance and saving of their basic electronic components. This doctoral disquisition investigates reverse engineering strategies with the main goal of extending the life of the device from the perspective of prevention, repair and reuse. At the same time, emphasis will be placed on sustainable design in order to select green materials and processes, so that fewer resources are spent and new future trends are integrated. Finally, applications and ways of analyzing the design for extending the life cycle of an electrical device will be developed.
