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.

This study examines global environmental sustainability in an open economy with international trade by studying the pattern of trade between the developed country and the developing country. Assuming that both economies are productive enough to grow and regulate pollution emissions optimally over time via emission tax, it is found that the developing country is bound to specialize in producing the pollution-intensive goods in a growing economy as long as there exists a sufficiently great technology gap in the production of environmentally friendly goods between the developed country and the developing country. The conclusion holds even if the marginal valuation of environmental improvement increases rapidly in the developing country. The developing country needs to export pollution-intensive goods where it has a comparative advantage in producing to finance imports of environmentally friendly goods that it values more over time. It is suggested that global cooperation for technological development to reduce pollution in the dirty manufacturing industry is needed to prevent ever-worsening environmental degradation in developing countries.

MFCA's potential as a GMT in the hospitality industry has not been well demonstrated. Instead, the manufacturing industry takes the credit for the successful implementation of MFCA. This may be attributed to the industry's inaccurate information on resource consumption and management for strategic internal decision-making. Greening in hotels has predominantly been viewed from customers' perspectives to gain a competitive advantage and improve profits. MFCA is presented in this chapter as a GMT to achieve eco-friendly hotel business practices via informed resource utilization data. Natural resources such as water and energy are gradually becoming scarce commodities with waste generation on the rise and environmental sustainability of the hotel business threatened. Hotels face pressure from the global market to improve their sustainability performance by implementing green practices. In meeting the requirements of sustainable practice, green management's goal focuses on reducing, eliminating, and preventing adverse effects arising from environmental activities.

In this paper, the treatability of strong wastes originating from an organic chemicals industry was studied. Literature data were evaluated to assess the applicability of conventional and advanced methods of treatment to highly concentrated wastewaters. A detailed treatability study was conducted on the wastewater, which was provided from a small-scale polyester manufacturing plant. The manufacturing process involved only esterification reactions, generating a wastewater with a COD content of over 200,000 mgl−1. The applicable treatment methods to be tested were determined as biological treatment of activated sludge process with low organic loading and chemical oxidation with H2O2. Results of the biological treatability study indicated that 80% COD removal could be obtained with 10 days retention time, provided that the system was fed with a 1/100 diluted raw wastewater. Chemical oxidation of raw wastewater with H2O2 in acid conditions and using ferric chloride as catalyst yielded 70% COD removal. However, the dosage required to obtain this efficiency was about 1 kg H2O2 per m3 of wastewater. With these applications the wastewater was treated to yield a COD of lower than 2000 mg/l. Results of the study were discussed and evaluated considering complexity and cost of treatment.

Environmental sustainability is an important component of a firm’s Corporate Social Responsibility. It relates to firm practices that ensure the conservation of the environment and natural resources, such as water, land and air. This research study aims to study the concept in relation to firm performance in Jordan. It proposes that environmental sustainability practices of a company in Jordan’s manufacturing industry positively influence its financial performance. For this purpose, the study assesses the relationship between environmental sustainability score and the profitability ratios. Results reveal a significant positive impact of sustainability score on the ROA of the companies. It is therefore recommended to manufacturing firms in Jordan to focus more on environmental CSR and sustainability practices, which would result in improved efficiency and profitability.

Industrial development has made major breakthroughs in the last decade in the wake of increased production, government policies and public demand. At the same time, problems related to environmental sustainability have become a major concern for producers. The unsatisfactory dimension of environmental protection has always been highlighted, because the environmental management system (EMS) is ignored and not consistently implemented in certain Tunisian companies. This increasing interest in environmental consciousness is pushing manufacturers to aspire to adopt successful environmental management strategies. Organizations are in fact increasingly responsible for monitoring and enhancing their environmental efficiency. The present work is intended to resolve these issues by establishing the essential factors and modelling their interrelationships in the Tunisian context. By reviewing literature and expert opinions, 14 critical factors have been identified which leads to responsive in the implementation of EMS- based ISO 14001. For better understanding, the MICMAC research was used to identify the critical variables according to their driving and dependence power. The present study highlights “Top management commitment and support” and “Government policies and legislation” as the most significant factors for ISO 14001 implementation. This research will facilitate organizations' readiness for implementation of ISO 14001 by providing a detailed understanding of mutual relationships among EMS factors based on ISO 14001.
