Digitalization represents a paramount process started some decades ago, but which received a strong acceleration by Industry 4.0 and now directly impacts all the process and manufacturing sectors. It is expected to allow the European industry to increase its production efficiency and its sustainability. In particular, in the energy-intensive industries, such as the steel industry, digitalization concerns the application of the related technologies to the production processes, focusing on two main often overlapping directions: Advanced tools for the optimization of the production chain and specific technologies for low-carbon and sustainable production. Furthermore, the rapid evolution of the technologies in the steel sector require the continuous update of the skills of the industrial workforce. The present review paper, resulting from a recent study developed inside a Blueprint European project, introduces the context of digitalization and some important definitions in both the European industry and the European iron and steel sector. The current technological transformation is depicted, and the main developments funded by European Research Programs are analyzed. Moreover, the impact of digitalization on the steel industry workforce are considered together with the foreseen economic developments.

Over the last few decades, process industries have invested increasing efforts in developing technical and operating solutions related to industrial symbiosis and energy efficiency in both production processes and auxiliary services. In particular, new technologies that enable industrial symbiosis, such as novel treatment processes for byproduct extraction and valorization, water purification, and energy transformation, were implemented in different sectors. This work analyses recent relevant results in the implementation of industrial symbiosis and energy efficiency solutions within process industries across Europe, based on the transactions of energy and material flows. Current developments, based on the circular economy’s transformation levers and related achieved results, were taken into account by considering the achieved results coming from the literature, EU-funded projects, programmes, and initiatives on the implementation of technical solutions and practices related to industrial symbiosis and energy efficiency. In addition, the most relevant challenges deriving from the implementations of industrial symbiosis and energy efficiency were analysed. A comprehensive picture of the sectors involved in achieving more proactive cross-sectorial cooperation and integration was provided, as well as an analysis of the main drivers and barriers for IS and EE implementation in future scenarios for European process industries.

Based on the results of the EU funded Social Innovation – Driving Force of Social Change (SI-DRIVE) project the major challenges and needs of education and lifelong learning worldwide are revealed, focusing on solutions via new educational practices delivered by social innovations and embedding civil society. Against this background, a more learner-oriented approach instead of institutional improvements is presented. Based on the results of SI-DRIVE’s global mapping of more than 200 innovative education initiatives and 18 in-depth case studies, the article spotlights the relevant settings and success factors of social innovations in education, leading to a system related typology of social innovation. New ways of repairing, modernising and transforming education as well as separated approaches are illustrated showing the underdeveloped, unexploited and unrecognised potential of this kind of innovation. For setting up a more innovation friendly environment, it is particularly important to realise a paradigm shift towards a learner perspective and rationality. More leeway and new governance structures for integrating and fostering social innovations and unfolding the potential of all societal sectors for enhancing education are necessary. This especially includes a more active and new role of universities in enabling, exchanging, moderating and researching social innovation.

Within the implementation of the Industry 4.0 paradigm in the steel sector, robots can play a relevant role in improving health and safety conditions at the workplace, by overtaking cumbersome, repetitive and risky operations. However, the implementation of robotics solutions in this particular sector is hampered by harsh operating conditions and by particular features of many procedures, which require a combination of force and sensitivity. Human–robot cooperation is a viable solution to overcome existing barriers, by synergistically combining human and robot abilities in the sense of a human-centered Industry 5.0. In this sense, robotics solution should be designed in a way to integrate and meet the end-users’ demands in a common development process for successfully implementation and widely acceptance. The paper presents the outcomes of the field evaluation of a robotic workstation, which was designed for a complex maintenance operation that is daily performed in the steel shop. The system derives from a co-creation process, where workers were involved since the beginning in the design process, according to the paradigm of social innovation combining technological and social development. Therefore, the evaluation aimed at assessing both system reliability and end-users’ satisfaction. The results show that the human-centered robotic workstations are successful in reducing cumbersome operations and improving workers’ health and safety conditions, and that this fact is clearly perceived by system users and developers.

New digital solutions are often lacking integration and acceptance by potential users. Therefore, only a small amount of innovative software solutions is really in use. The article describes a co-creation process by integrating end-users and relevant stakeholders right in the beginning in a social innovation process. Within this process, technology is seen as an enabler of innovation getting its relevance from new social practices of the people using it (e.g. working practices). Against the background of EU funded projects conducted by the authors (GT-VET, GREEN STAR, COCOP, and ROBOHARSH) the relevance of mutual learning processes of engineers / researchers / trainers on the one side and end-users / beneficiaries / learners on the other side will become evident. Moreover, new (digital and analogue) skills of employees have been identified as key for a successful digital transformation. Thereby, this article shows a twofold perspective on social innovation in education: new skills demands for employees and mutual learning processes of developers and users/stakeholders. To obtain needed skills, traditional innovation practices have to be changed by setting up a social innovation process. Such a process design has to include stakeholder and user involvement beyond pure feedback on a new technology. Co-creation means that experience, knowledge and ideas of users will be considered to ensure high usability and impact of the new technology framed by organisational and people related measures. In this respect, the innovation process and the innovation itself is much more than technological functionality–it is a contribution to new social practices and performances of the people that innovate and use the technology.

The technological transformation in the European steel industry is driven by digitalization, which has the potential to strongly contribute to improving production efficiency and sustainability. The present paper describes part of the work developed in the early stage of the project entitled “Blueprint ‘New Skills Agenda Steel’: Industry-driven sustainable European Steel Skills Agenda and Strategy (ESSA)”, which is funded by the Erasmus Plus Programme of the European Union. The project aims at achieving an industry driven, sustainable and coordinated blueprint for addressing the economic, digital and technological developments, as well as increasing energy efficiency and environmental demands through continuously update of qualification, knowledge and skill profiles of the workforce. On the one hand, main aspects of the current state of the technological transformation in the steel sector are described through the analysis of the main recent innovation projects and developments. On the other hand, survey results from a dedicated questionnaire addressed to the European steel companies are analyzed, providing an overview on the (planned) technological transformation affecting the steel sector. The existing levels of plant automation and the possible adoption of the new paradigm of Industry 4.0 are discussed, by also considering the possible impact on the workforce. Main results are that the steel industry foresees an implementation of almost all Industry 4.0 technologies not only for competitive but also environmental improvement. Because this is foreseen in an incremental way upskilling of the existing workforce is a precondition, not only because of recruitment difficulties on the employment market but also because the existing qualification and experience of the workplace is necessary to unfold the full potential of digital and green transformation.
