Abstract
Purpose
Mine tailings are solid waste left after extracting the valuable fraction of the ore. This study reviewed the possibility of using copper-tailing waste to develop building foundations and compared its environmental implications with conventional sand foundations.
Design/methodology/approach
This study first discusses the state-of-the-art use of copper tailings in various industries through a literature review. The study then uses the life cycle assessment (LCA) methodology to quantify and compare the environmental impacts generated by the conventional sand and tailing foundations for buildings by considering a 1 × 1 m foundation area. The study also assessed the environmental impacts of a real copper mine case of the Khetri Copper Complex in the state of Rajasthan, India, and conducted a sensitivity analysis to show the impact of transportation distance on environmental impacts using the Monte Carlo simulation technique.
Findings
The study results indicate that the building foundation developed using copper-tailing waste is environmentally beneficial compared to a sand foundation. The sensitivity analysis results indicate that the transportation of tailings reduces the environmental benefits if transported over long distances; however, the utilisation is helpful for environmental sustainability. We further discussed the managerial and social implications of the results.
Originality/value
This study is a novel contribution highlighting the sequestration potential of copper tailing waste utilisation using midpoint and endpoint environmental impact categories.

Abstract
Purpose
This study aims to quantify and compare the environmental impacts of Marble-stone and Kota-stone flooring options widely used for buildings in India. The study discusses the possibility of carbon sequestration through Bamboo cultivation in India.
Design/methodology/approach
The study has followed a standard life cycle assessment (LCA) framework based on ISO 14040 guidelines. Three distinct phases have been compared on midpoint and endpoint assessment categories – raw material, polishing and disposal. Primary data has been collected from the construction site in India, and secondary data has been collected from the Ecoinvent 3.0 database. Previous studies have been referred to discuss and calculate the area of bamboo cultivation required to sequestrate the generated carbon from the flooring.
Findings
The study has found that endpoint category damage to resources, and midpoint categories of climate change, metal depletion and agricultural land use are highly impacted in building floorings. The study has also found that the Marble-stone floor generates higher environmental impacts than the Kota-stone floor in most of the midpoint and endpoint impact categories. This difference is significant in the raw material phase due to the different compositions of stones. The study also found that Bamboo has excellent potential to act as a carbon sink and mitigate the generated carbon.
Research limitations/implications
This study excludes human labour, cutting and distribution of floor tiles made of Marble-stone and Kota-stone. The researcher can use the study to evaluate, compare and benchmark the various building flooring options from the environmental perspective. The study aids to the body of knowledge available on the various building flooring options by presenting the LCA or the environmental impacts generated by two flooring options. It is expected that the architects and builders can use these results to develop carbon-neutral buildings. This study provides a methodology for governments, constructors, builders and individuals to evaluate, compare and benchmark the various construction materials from the environmental perspective by computing the environmental impacts throughout the life cycle of the materials.
Originality/value
This study compares two widely used building flooring options using the LCA methodology and evaluates the potential of bamboo cultivation near the buildings for carbon sinks. The study is unique because it shows the environmental impacts of two flooring options and the carbon sequestration method to mitigate/absorb the generated environmental impacts in or around the building itself through bamboo cultivation. This study may set the foundation for carbon-neutral buildings.

Abstract
Purpose
The purpose of this paper is to compare environmental performance of two shackle insulator manufacturing enterprises in India by evaluating and quantifying the life cycle environmental impacts in these enterprises using ISO 14040 guidelines.
Design/methodology/approach
All relevant life cycle phases – raw material, manufacturing, transportation and disposal – are considered. Primary inventory data for the two enterprises are collected through observations of processes at the sites. Ecoinvent 3.0 database is used as secondary data source. Process flow models are developed using Umberto software. ReCiPe impact assessment methodology is adopted to calculate environmental impacts in terms of endpoint categories of ecosystem quality, human health and resource availability; and midpoint categories of climate change, fossil depletion, human toxicity, metal depletion, ozone depletion, terrestrial acidification and water depletion.
Findings
This study has found that manufacturing phase followed by raw material extraction and transportation phases are responsible for most of the environmental impacts. This study also found that raw materials used in glaze preparation (manganese and ferrite), electricity, heavy fuel oil (C-9) and cotton have high environmental impacts in the manufacturing phase.
Research limitations/implications
The limitation of this study is that most of the inventory data are collected from only two manufacturing plants.
Practical implications
The researchers/enterprises can use the knowledge body for modelling and result comparison under different conditions. The enterprises can do the micro analysis of environmental effects of processes to improve environmental as well as economic performance. The government agencies can use the data for policy development and deployment.
Originality/value
The main contribution of the research is the creation of a knowledge body in the area of ceramic product environmental impacts. The paper provides inventory for the life cycle assessment (LCA) of shackle insulators using primary source (measured values) as no secondary data source is available for the shackle insulators. The inventory and results of this study can be used as reference for the future LCA studies in ceramic industry.

Abstract
Purpose
There is a dichotomy in the actual and expected environmental performances of the Indian enterprises even though the Indian enterprises have aligned their businesses with intended nationally determined contributions (INDC) targets. The purpose of this paper is to analyze the supply chain of Indian enterprises to understand influences to adopt green practices throughout the supply chains, and how these green practices influence economic, operational and environmental performances to reveal the underlying currents explaining difference in actual and expected performance.
Design/methodology/approach
Five research propositions are developed based on the existing literature. Data are collected from 233 ceramic enterprises in India. Exploratory factor analysis has been done to test construct validity and correlation. Confirmatory factor analysis is used to check unidimensionality of constructs. Structural equation modeling is used to test the strength and direction of the relations between the constructs and to develop the model.
Findings
The findings of the study suggest that the Indian companies have aligned their businesses with INDC targets but they have not adopted the green practices in inbound and outbound supply chains; therefore, the actual environmental performance is not as expected. Other major finding is that the enterprise and government are not focusing on the informative pressure and instead the focus is on coercive techniques which are not yielding positive results. The statistical results show that the adoption of green practices led to the improvements in environmental and operational performances but reduction in economic performance.
Originality/value
This paper has analyzed green supply chain management pressure, practice and performance measure for Indian ceramic enterprises and proposed a structural model with their interrelation.

Abstract
Purpose
The concept of green supply chain management (GSCM) is evolving rapidly due to the environmental concerns and gaining popularity in the research community. This study critically analyze the literature of GSCM pressure, practice and performance for manufacturing enterprises based on the results of bibliometric, network and frequency analyses.
Design/methodology/approach
Scopus database is used for literature search. Bibliometric network and frequency analysis are used to critically review the evolution of identified constructs and measures of GSCM pressure, practice and performance.
Findings
This study has identified that the selected topic is in growing stage through the collaborative effort of the worldwide researchers. This study also shows the diffusion of influence in developing countries and there are enormous opportunities of research in these regions. The study finds evaluation of GSCM constructs and measures with time and shift in focus areas by the researchers. The study suggests more focus on the measurement of informative pressures, reverse logistics practices and negative impact on economic performance due to the adoption of GSCM practices. There is a need of simultaneous analysis of GSCM pressures, practices and performance to identify the cascading effect in different regions and industrial sectors and developed a conceptual framework to identify this effect. This study also observes the need of more quantitative measures-based case studies and suggests the use of life cycle assessment for the quantification of environmental performance.
Originality/value
This study for the first time has analyzed a specific topic of GSCM pressure, practice and performance through bibliometric and network analyses. This study critically reviews the constructs and measures of GSCM pressure, practice and performance and identified the future research directions.

Abstract
Purpose
The purpose of this paper is to aim at prioritizing and identifying the interrelations among the green supply chain management pressures, practices and performance measures. The study also compares the reasons of green supply chain management implementation, levels of implementation and improvement in performance for medium and large Indian ceramic enterprises because of green supply chain management implementation.
Design/methodology/approach
The most frequent constructs and measures of green supply chain management pressure, practice and performance are identified from the literature. The identified measures are corrected/added/removed, as per the suggestions of industry professionals, to develop a survey instrument. An interpretive structural model is developed to prioritize the constructs. Matriced “impacts croises-multiplication applique” and “classment” (MICMAC) analysis is done to identify the driving and dependence powers of the constructs. The identified results are validated through the descriptive analysis of responses obtained from multiple case studies.
Findings
It is observed that the informative pressures followed by coercive and mimetic pressures are the main drivers for the implementation of green supply chain management practices. Internal environmental management in enterprises is found to be the driving power behind the implementation of other green supply chain management practices. The implementation of these practices drives the environmental and operational performance. It is observed, through the multiple case study analysis that the impact of the pressures to adopt green supply chain management practices is high on Indian ceramic enterprises but the implementation of practices is in the early stage. The improvement in performance is also not found to be significant at this stage. This study also found that large ceramic enterprises are doing better than the medium enterprises in terms of green supply chain management implementation, largely because of higher pressures and availability of resources.
Originality/value
This study prioritizes the constructs of green supply chain management pressure, practice and performance for Indian ceramic enterprises and compares the large and medium enterprises on the basis of these constructs.

Abstract
Purpose
The purpose of this paper is to identify and analyze the impact of green supply chain management (GSCM) pressures, implementation level of GSCM practices and improvement in performance of the Indian ceramic enterprises. The paper also aims at benchmarking the Indian ceramic enterprises based on enterprise size and market orientation (export activity).
Design/methodology/approach
The research is based on the empirical study of Indian ceramic industry. Propositions are developed to study: the impact of GSCM pressures, implementation level of GSCM practices, improvement in GSCM performance, and the effect of GSCM pressures on implementation of practices, and impact of GSCM practices on GSCM performance. Data are collected from Indian ceramic enterprises of different sizes. Exploratory factor analysis is performed to segregate the pressures, practices and performance variables into constructs. Two-step algorithm, with log-likelihood measures of distance and Bayesian information criterion, is used to decide the optimal number of clusters. These clusters are compared and benchmarked according to the enterprise size and export activity.
Findings
This study finds that the implementation level of GSCM practices is higher in large- and medium-size enterprises as compared to small-size enterprises. Large- and medium-size enterprises have high impact of mimetic and informative pressures and small enterprises have high impact of coercive pressure (CP). Although the CP is high on small enterprises but due to the limited resources, these enterprises cannot afford to implement GSCM practices. The implementation of GSCM practices results into the improvement of environmental and operational performance but decrease in economic performance.
Practical implications
The findings of this study will suggest the policy maker to encourage the diffusion mechanism through a collaborative partnership with larger enterprises to enhance the implementation level of GSCM practices in small-size enterprises.
Originality/value
The novelty of the paper are: it analyzes and benchmarks GSCM pressures, practice and performance for Indian ceramic enterprises by considering enterprises size and export activities as control variables, and it finds the effect of GSCM pressures on the implementation level of GSCM practices and improvement in enterprise performance for Indian ceramic enterprises.

Abstract
Purpose
The purpose of this paper is twofold: first, to develop a statistically reliable and valid model of performance measures (PMs) to observe the environmental behavior of different enterprises; second, at benchmarking the enterprises based on their green practices.
Design/methodology/approach
A PM model has been proposed using an empirical analysis of manufacturing industry. The developed model has been tested using structural equation modeling technique. The level of green manufacturing (GM) performance in different sectors and sizes of Indian manufacturing industry has been studied and benchmarked using hierarchical cluster analysis with one-way ANOVA.
Findings
The results indicate that top management commitment and product design are the root PMs for the success of GM practices. It has been found that chemical, automotive, food and pharmaceutical industries are the high performing sectors. It has also been found that large scale enterprises are performing better than medium-sized enterprises which are doing better than small and micro enterprises in GM practices.
Research limitations/implications
The indicators/variables in questionnaire are subjective in nature and collected data are from Indian manufacturing organizations only.
Practical implications
The governments, trade bodies and NGOs can use the proposed model for measurement of green performance of any manufacturing industry. The benchmarking can be used by the different policy influencing and making agencies to develop future policies for the improvement. The industry can also use the benchmarking for its peer performance improvement.
Originality/value
The major novelty of the paper is benchmarking the green performance of manufacturing industries based on the different sectors and sizes using empirical investigation. The level of GM performance in different sectors and sizes of industries has been studied and benchmarked using hierarchical cluster analysis with one-way ANOVA.

Abstract
Purpose
In the time of coronavirus disease 2019 (COVID-19) epidemic, the effective leadership is what all the organisations are now requiring. Retaining and satisfying the employees in these tough times has become very difficult. In view of this, the present study attempts to investigate three objectives: first, to find out the direct effect of effective leadership on job satisfaction and organisational citizenship behaviour (OCB); second, to examine the relationship between job satisfaction and OCB and, third, to investigate whether effective leadership positively moderate and mediate the link between job satisfaction and OCB among managerial employees of private manufacturing firms of Chhattisgarh state.
Design/methodology/approach
Correlational research design was applied in the present study. Cluster sampling was used to finalise sample region, and simple random technique was applied to collect primary responses. Employees working at the managerial positions were chosen as participants in the present study. About 530 questionnaires were sent to the participants in which 400 responses were found useable for analysis.
Findings
The results explained a significant relation of effective leadership with job satisfaction and OCB. In addition, job satisfaction also revealed a positive correlation with OCB. The moderating and mediating effect of effective leadership in the link between job satisfaction and OCB was also noted in significant association.
Originality/value
Private sector enterprises were economically harmed by COVID-19's sudden arrival. This forced corporations to minimise expenses by cutting staff, production and operations. Employees felt alone, needed assistance and guidance. This research demonstrates how effective leadership may reconnect workers and boost organisational performance.
