The research question was whether the implementation of the digitization process based on Industry 4.0 resulted in changes to the organizational structure of the company and whether this brought about an improvement in the energy and material efficiency of the company. The research method used in the paper was the case study method. In view of the project’s results, we concluded that implementation of the new solution based on digitalization caused increased energy and material efficiency, often forced by external factors stemming from the operation of competitive markets. Technological changes also require the application of IT technologies and communication systems in managing production. Access to this information is also a chance to gain a competitive advantage.
