“…Compared to coal, plastics have a greater H2 content and lesser CO2 emission. Plastic substitution lowers the process temperature by at least 100-200 8C, improving the process's energy efficiency (Hodgkinson and Smith, 2021;Tong et al, 2019;Devasahayam et al, 2019). Scrap utilization also helps in achieving energy efficiency as it does not require a blast furnace and follows electric arc furnace route (Yellishetty et al, 2011).…”

PurposeThe main purpose of this paper is to investigate drivers and barriers of climate change mitigation strategies (CCMS), their linkages and impact in Indian Iron and Steel Industry (IISI) in light of ninth sustainable development goal (building resilient infrastructure, promote sustainable industrialization and foster innovation).Design/methodology/approachTo identify relevant drivers and barriers, a thorough literature review and opinions of industry experts were obtained. Utilizing Total Interpretive Structural Modeling (TISM), the selected drivers and barriers were modeled separately along with Cross Impact Matrix-multiplication Applied to Classification (MICMAC).FindingsPragmatic and cost-effective technology, less supply chain complexity, robust policy and legal framework were found to have the highest driving power over all the other drivers. Findings suggest political pressure as the most critical barrier in this study. The results from TISM and MICMAC analysis have been used to elucidate a framework for the understanding of policymakers and achieve top management commitment.Practical implicationsThis paper will help researchers, academicians, industry analysts and policymakers in developing a systems approach in prioritizing CCMS in energy-intensive (coal dependent) iron and steel plants. The model outcomes of this work will aid operational research to understand the working principles in other industries as well.Originality/valueTo the best of authors' knowledge, there is paucity of reported literature for the drivers and barriers of CCMS in iron and steel industry. This paper can be considered a unique, first attempt to use data from developing nations like India to develop a model and explain relationships of the existing drivers and barriers of CCMS.

“…Shekhari et al (2011) studied the factors influencing the green supply chain and emphasized on waste management, minimizing soil, air and water pollution and strict compliance to government regulation. It is being increasingly rewarding for steel mills to follow the 3R’s – reuse, reduce and recycle when it comes to water usage (Tong et al , 2019). Nezamoleslami and Hosseinian (2020) discussed the broad application of the water footprint concept in steel plants.…”

Purpose The purpose of this paper is to establish the structural relationships between the environmental sustainability enablers (ESEs) for the steel supply chain in India and also to classify them on the basis of driving and dependence power with an objective of achieving enhanced environmental sustainability performance. Design/methodology/approach The ESEs were identified through extensive literature review and discussion held with experts from the Indian steel industry. The interpretative structural modeling (ISM) approach was applied to an Indian steel supply chain to arrange these 12 ESEs in different hierarchies of the structural framework on the basis of their driver dependence power and also diagraph was developed to classify them. Findings The water pollution control system, air pollution control system and soil pollution control system were found to be in the bottom hierarchy of the ISM framework and these enablers were also observed in the driving quadrant of the diagraph. These driving enablers should be given priority for its full-scale development, management and monitoring to sustain and enhance the environmental sustainability in the Indian steel supply chain, whereas top management commitment, environment compliance certification and government regulation and incentives are the antecedents for carrying out the sustainability program. Research limitations/implications The outcomes of the current study are limited to the Indian steel manufacturing company in specific but the results will not change significantly for the steel sectors in India. However, an empirical analysis can be used to explore and validate the structural framework for its acceptability. Practical implications The outcomes from the methodology provide the basis for an Indian steel manufacturing industry to develop the right strategy in their quest for environmental sustainability. Originality/value Although the study on ESEs of various industries was reported in the literature, the comprehensive study to identify the significant ESEs related to the Indian steel supply chain for environmental sustainability in specific have been hardly carried out. The current study will definitely be a valuable addition to environmental sustainability literature in general and steel supply chain environmental sustainability in specific.

“…The environmental performance of these systems is assessed through LCA in these instances, which involve the evaluation of an integrated wastewater system, as was the case with the assessments conducted in Italy [Arfelli et al, 2022], Brazil [Lima et al, 2022], Portugal [Boldrin & Formiga, 2023], which demonstrated that water withdrawal and water treatment contributed more to the majority of environmental impact categories due to the electricity consumption associated with these processes. Tong et al [2019] explained that stages of wastewater treatment and disposal made substantial contributions to the categories of eutrophication and marine ecotoxicity. According to the findings of Cardoso et al [2021]; Mannan and Al-Ghamdi [2022], the primary environmental consequences falling under the category of global warming stem from the energy-intensive phases of distribution, collection, pumping, and wastewater treatment plants (WWTP).…”

In the face of increasing global challenges, such as water scarcity, population growth, and environmental degradation, sustainable management of water resources and wastewater treatment is a major concern. However, sometimes the potential impact of water system management on the environmental implications contained in the production process of water and waste treatment systems is omitted. This study sought to assess the environmental efficacy of an integrated water supply and wastewater system in the Semarang City. The secondary objectives of the study were to ascertain the extent to which each stage of the system contributed to the impact categories that were analyzed. Life cycle assessment is a method to evaluation of the environmental impacts associated with water resource and wastewater management, using 1 m 3 as functional unit. The stages of water use are not examined in this study. Another restriction is the absence of information about the city's untreated wastewater quantities' final destination. Water treatment plant include water withdrawal and water distribution are most impacted under the climate change environmental impact category and other impact that assess until 99%. In seven of the eight impact categories examined, power consumption is the most impactful input.
