“…In fact, the industry is currently in the stage of industrial restructuring, and great changes will arise in production structure and technical level to solve pressing issues, such as overcapacity, high energy intensity (EI), and carbon emission. These changes will directly affect the global energy consumption and carbon emissions [20].…”

“…Other models of the processes related to steel and iron production [17]; [18]; [19]; [20]; [21] and their main indicators (energy efficiency and energy intensity [22]) were researched, from the point of view of the mode in which such models are taking into account not only the flows of mass, energy, and time but also their conservation.…”

Literature so far illustrates different approaches to achieving circular economy (CE). It is increasingly important that every industry explores opportunities to transitioning towards CE doing it through process streamlining or via uses of technology to transform/exchange the resources. We recognize the difficulties faced by researchers in consolidating key aspects to CE, due to still fragmented knowledge base. To clearly identify these aspects is somewhat difficult due to the fragmented knowledge over applications of circular economy. However, any holistic approach is possible by considering the performance of the growth (in our temporal visible world) and that of innovation and creation as a result of the introspection of the temporal invisible world (thought and inspiration), in terms of three fundamental scalars in nature, mass, energy, and time transformed by natural action and human action, in order to define the circularity for any group, category, and type of product. We consider that the effect of any action should be evaluated by determining the most probable results and the dynamic of any process (using statistics), by considering the transformation of the three fundamental scalars. This article presents a consonant approach of the economy, aiming to optimize the intervention of humans in the natural environment and its performance and having the scope of the integration of the human actions in the natural cycles, to secure sustainability.

“…Apart from some slight oscillations due to technical details, it is commonly accepted that steelmaking consumes over 560 kg of Coal Equivalent [148] and produces an average of 1.85 carbon dioxide tonnes per tonne of structural steel [147]. Thus, reported weight reductions of 18% to 75% in steel connections [139,[149][150][151], by employing TO, are expected to have a critical impact in steel construction goals.…”

Topology Optimisation is a broad concept deemed to encapsulate different processes for computationally determining structural materials optimal layouts. Among such techniques, Discrete Optimisation has a consistent record in Civil and Structural Engineering. In contrast, the Optimisation of Continua recently emerged as a critical asset for fostering the employment of Additive Manufacturing, as one can observe in several other industrial fields. With the purpose of filling the need for a systematic review both on the Topology Optimisation recent applications in structural steel design and on its emerging advances that can be brought from other industrial fields, this article critically analyses scientific publications from the year 2015 to 2020. Over six hundred documents, including Research, Review and Conference articles, added to Research Projects and Patents, attained from different sources were found significant after eligibility verifications and therefore, herein depicted. The discussion focused on Topology Optimisation recent approaches, methods, and fields of application and deepened the analysis of structural steel design and design for Additive Manufacturing. Significant findings can be found in summarising the state-of-the-art in profuse tables, identifying the recent developments and research trends, as well as discussing the path for disseminating Topology Optimisation in steel construction.
