“…In the process of coal mining, steel is the main material of roadway support. Steel recycling is a typical example of circular economy, which cannot only save energy and resources, but also reduces the discharge of waste (Liu et al 2020; Wübbeke and Heroth 2014). Tongpool et al (2010) con rmed that the recycling of scrap steel can effectively reduce the impacts of fossil resources, ecological toxicity, carcinogenicity and so on.…”

Coal occupies an absolute advantage in the primary energy structure of China. However, the production of coal poses a serious threat to the ecological environment and human health. In order to quantify the environmental impact of coal mining, this study used the life cycle assessment (LCA) method to analyse the life cycle of coal mining from the cradle- to-gate. Midpoint results based on ReCiPe 2016 indicated that coal mining had a remarkable impact on human carcinogenic toxicity, marine ecotoxicity, freshwater ecotoxicity, fossil resource scarcity, and human non-carcinogenic toxicity. The contribution analysis revealed that material production was identified as the main cause of environmental impacts, followed by energy consumption and process emissions. Steel consumption, electricity production and wastewater discharge were identified as key environmental pollution processes. In addition, specific environmental pollution substances and their contributions were recognized from the source, and sensitivity analysis between key processes and key impact categories was carried out. At the endpoint level, coal mining led to the most damage to human health, followed by ecosystems and resources. This study is of reference significance in guiding the construction of green mines and achieving sustainable development of coal resources.

“…The physical conditions inside the production facility can be seen as a consequence of the production process, which in the case of steel plants can be classified as extreme [34]. As such, the steel manufacturing process imposes high demands on plant equipment on the production floor [35], but consequently also on network and SCADA systems, and therefore posing an industry-specific requirement that shapes the future development of various system control segments.…”

Recent technological advances encompassed by the smart factory concept have fundamentally changed industrial control systems in the way they are structured and how they operate. Majority of these changes affect Supervisory Control And Data Acquisition (SCADA) systems, shifting them to a higher level of interoperability, heterogeneous networks, big data and toward internet technologies and services in general. However, this transformation does not affect all SCADA systems equally. The immediate industrial environment and controlled processes have a significant impact as well. This paper presents a holistic approach to SCADA systems implemented in continuous flow production control within the steel industry production environment. We outline the multi-layer architecture of the SCADA control framework and the aspects of interoperability and interconnection within the architecture reference models, together with the research challenges and opportunities arising from the recent rapid increasement of the industrial control systems complexity and digital transformation under the Industry 4.0 paradigm, resulting in disrupting levels of the traditional automation pyramid based on Purdue model toward a higher level of integration and interoperability enabling cross-level data exchange empowered by the Industrial Internet of Things. Furthermore, the paper addresses the problem of proprietary SCADA systems and elaborates the causal correlation between SCADA quality requirements and adoption of new technology in relation to the specific industrial environment of the steel manufacturing process.

“…Climate change can be brought on by greenhouse gas emissions from industrial operations, hence this issue needs to be addressed [6]. A total of 84.26 million tonnes of crude steel were produced in 2019, more than double the amount produced over the previous three decades [7]. A difficulty is that, in addition to the anticipated rise in infrastructure development and demand for construction steel, there may also be significant environmental risks from the steel manufacturing process.…”

One of the biggest energy consumers and CO2 emitters in the world is the steel sector. With the growth in infrastructure construction, steel output has risen year over year. Therefore, a life cycle assessment of inputs and outputs at each stage of the steel manufacturing process is necessary to enable the adoption of life cycle management and offer sustainable production and consumption. The Life Cycle Assessment method is employed in this study to assess the environmental effects of steel manufacturing in Indonesia. The CML-IA baseline method, which assesses several impact categories including global warming, ozone layer depletion, acidification, and eutrophication, and others impact was used in this study and SimaPro 9.2 software was used to calculate the environmental impact of steel production. According to the findings, the largest contributors to the overall impact are the electric arc furnace, rolling mills, ladle furnaces, which use chemicals, and reheating furnaces, which use LPG. The entire impact of the steel manufacturing process on global warming, using a functional unit of 1 ton steel, is 1215.17 kg CO2 eq, of which the Electric Arc Furnace (EAF) contributes 477.37 kg CO2 eq, or 39% of the total CO2 emissions. Based on these findings, an effort is therefore required to reduce the consumption of fuel in the reheating furnace as well as electricity in the EAF and rolling mills.
