Recently, a paradigm called Industry 4.0 has brought important concepts that can contribute to environmental, economic and societal sustainability. Technologies like cyber-physical systems, cloud computing or visual analytics may be linked to bring transparency to industry increasing sustainability. However, to implement those technologies in machines and factories shop floors, some important subjects like sensor technologies, data gathering systems, virtual simulation or human factor have to be outlined. As a result of an initiative towards Industry 4.0, use examples of the abovementioned subjects, based on analysis over relevant industrial companies, have brought up difficulties related with the possibilities to implement the appropriate infrastructure to push in the so-called industry paradigm shift. As preliminary result of this initiatives, recommendations based on Etxe-Tar own experience, are given in order to get a clear view of the opportunities to achieve an optimum implementation of Industry 4.0 technologies and enable sustainable process.
