This study investigates the barriers and strategies related to the installation of smart factories in the manufacturing domain, with a focus on the manufacturing industry integrated with a German company as a case study. Utilizing the Best Worst Method (BWM), 47 performance variables were assessed and ranked in nine key groups, revealing significant factors that influence the installation of the smart factory. Technological challenges, complexity, and integration emerged as critical priorities, emphasizing the essence of robust IT infrastructure and agile software development practices. Additionally, e-waste management and energy efficiency were highlighted as imperative aspects for sustainable smart factory operations. Ethical considerations, including worker safety standards and data governance, were emphasized for ethical and societal sustainability. Theoretical implications elucidate the contribution to existing knowledge by identifying and ranking key barriers, revealing effective strategies, and expanding understanding in specific areas such as e-waste management and ethical supply chain methodology. Practical contributions offer insight to optimize the design and implementation of smart factories, focusing on strategic prioritization, comprehensive planning, and ongoing adaptation. Nevertheless, it is essential to acknowledge limitations, including the reliance on expert opinions, sector-specific applicability, and the need for larger sample sizes. Future research avenues could include cross-industry comparative studies and the incorporation of cutting-edge technology like blockchain and artificial intelligence (AI). Ultimately, this research offers insightful knowledge about the challenges and opportunities of smart factory installation in the manufacturing sector, particularly in Germany. By clarifying identified barriers and adopting recommended strategies, organizations could navigate the complex landscape of smart factory adoption and contribute to the ongoing digital conversion of the industrial sector.

“… 354 Therefore, most pyrometallurgical plants must include a gas treatment facility and periodic measurement of dust, metals, SO , NO , and CO is required. 355 Gas scrubbing also decreases fouling, corrosion and erosion problems of downstream components such as heat recovery units and CCU equipment. More specifically, pre-treatment of flue gases is critical for further CO 2 utilization as some components present in off-gases may act as a poison for catalysts.…”

Metals and alloys are among the most technologically important materials for our industrialized societies. They are the most common structural materials used in cars, airplanes and buildings, and constitute the technological core of most electronic devices. They allow the transportation of energy over great distances and are exploited in critical parts of renewable energy technologies. Even though primary metal production industries are mature and operate optimized pyrometallurgical processes, they extensively rely on cheap and abundant carbonaceous reactants (fossil fuels, coke), require high power heating units (which are also typically powered by fossil fuels) to calcine, roast, smelt and refine, and they generate many output streams with high residual energy content. Many unit operations also generate hazardous gaseous species on top of large CO2 emissions which require gas-scrubbing and capture strategies for the future. Therefore, there are still many opportunities to lower the environmental footprint of key pyrometallurgical operations. This paper explores the possibility to use greener reactants such as bio-fuels, bio-char, hydrogen and ammonia in different pyrometallurgical units. It also identifies all recycled streams that are available (such as steel and aluminum scraps, electronic waste and Li-ion batteries) as well as the technological challenges associated with their integration in primary metal processes. A complete discussion about the alternatives to carbon-based reduction is constructed around the use of hydrogen, metallo-reduction as well as inert anode electrometallurgy. The review work is completed with an overview of the different approaches to use renewable energies and valorize residual heat in pyrometallurgical units. Finally, strategies to mitigate environmental impacts of pyrometallurgical operations such as CO2 capture utilization and storage as well as gas scrubbing technologies are detailed. This original review paper brings together for the first time all potential strategies and efforts that could be deployed in the future to decrease the environmental footprint of the pyrometallurgical industry. It is primarily intended to favour collaborative work and establish synergies between academia, the pyrometallurgical industry, decision-makers and equipment providers. Graphical abstract Highlights A more sustainable production of metals using greener reactants, green electricity or carbon capture is possible and sometimes already underway. More investments and pressure are required to hasten change. Discussion Is there enough pressure on the aluminum and steel industries to meet the set climate targets? The greenhouse gas emissions of existing facilities can often be partly mitigated by retrofitting them with green technologies, should we close plants prematurely to build new plants using greener technologies? Since green or renewable resources presently have limited availability, in which sector should we use them to maximize their benefits?
