Air pollution is the combination of fine particles and gases in the atmosphere that harm humans and animals. Our objective is to find the various air pollution contaminants and its repercussion on Homo sapiens’ health. We discuss how air quality is measured with the air quality index and measures that help us cope with the consequences of air pollution. To carry out this study, we carried out a systematic literature review to uncover the different dimensions of air pollution and mitigation strategies. From the existing literature and observations of the different data sets, we can conclude that air pollutants have a severe impact on the life of Homo sapiens, causing various diseases such as respiratory issues, skin diseases, etc. Today, we have ample laws, but the need of the hour is to initiate new policies to change the behavioural of Homo sapiens. Our findings will help in decision-making by stakeholders such as policy-makers, manufacturing industries, households, etc. This article will also help in highlighting the need for Homo sapiens behavioural change.

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.

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.

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.

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.

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.

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 purpose of this paper is to analyze the Environmental Sustainability Enablers (ESEs) for an Indian steel manufacturing company to select the appropriate set of ESEs for implementing and enhancing environmental sustainability.

A methodology using fuzzy Decision-Making Trail and Evaluation Laboratory (DEMATEL) is proposed to analyze ESEs capturing multiple experts’ qualitative judgments on their mutual impacts. It is applied to an Indian steel manufacturing company to understand the salient features of the concept.

The relevant 18 ESEs were classified into cause and effect group and also interactions (i.e. influencing and influenced) of each ESE with other ESEs were evaluated. It was observed that the five ESEs (i.e. competitors’ environmental sustainability strategy, environmental compliance certification, government regulations and incentives, influence of external factors and air pollution controlling system) are the most prominent in the cause group.

The results obtained are specific to an Indian steel manufacturing company and it cannot be generalized for steel manufacturing sector. However, the current paper can show direction to carry out such work in other manufacturing companies.

The proposed methodology will be helpful for allocating efforts and resources to enhance the impact of ESEs for successful achievement of environmental sustainability.

No such paper has been reported in the literature with an objective to develop structural framework for Indian steel manufacturing company to improve environmental sustainability.

Low installation and running costs, coupled with reduced maintenance requirements and improved levels of safety, are the principal features of a new air pollution control system for use within the plastics processing and coatings industries. The condenser filtration system from the Environmental and Thermal Engineering Division of the AELETE Group has applications wherever visible emissions due to hydrocarbon contaminants are generated.

To minimise the problems of environmental pollution normally associated with the production of blown vinyl wallcoverings, a purpose‐designed pollution control and heat recovery system has been commissioned by Burlington Wallcoverings at its new plant in Blackburn, Lancashire.

The fast depletion of natural resources that has resulted in the scarcity of resources and degradation of environment and the subsequent conflict over resources within and among the states have given rise to a growing concern for environmental security all over the world. It may be pointed out here that since the beginning of human civilization, humans have been relying on the environment for their needs and demands. Therefore, the concern of human beings to the environment has been always and obvious. But now with the depletion of natural resources, the concern for environmental security is being advocated. The purpose of this paper is to analyze environmental issues in the context of South Asia. It may also be added here that in a situation as stated above, any stress on the environment can cause conflicts involving violence within the state as well as between the nation states. Moreover, this paper will look into other issues related to the environment degradation in India and Bangladesh.

The first approach confines environment to the nature and the problems and constraints related to it. It can be termed as ecological approach. This approach is too narrow in its scope, as nature alone is not responsible for many types of hazards. How it is being exploited and protected is equally important. The other approach has been termed as the maximize approach and it includes both the ecology and its human domains. This approach takes into consideration the interaction between the two. It believes that the excessive dependence of human beings affects the environment. Also, the depletion and degradation of the environment affect human beings. The environmental security has to include both the domains and understand their inter-linkages. In fact, the uses of environment and its proper maintenance are related to the human domains.

The environment-related problems and their implications are more similar in both countries. It is true that there is a growing awareness on environmental issues in almost all the countries in the last few years and the individual countries have persuaded environment-friendly policies in certain sectors. Apart from this regional level, a common approach to securing the environment may involve the following aspects: sharing of knowledge and expertise regarding population control measures, policies and programs; cooperation for development and poverty eradication; regularization of inter-state migrations, evolving a regional framework for controlling, repatriation and rehabilitation of refugees; establishment of a system of disaster management and disaster preparedness at the regional level; exchange of knowledge and research works on seismic tremors, earthquakes, and landslides, their causes and possibilities; evolving common flood control measures and development of a regional flood warning system; common measures can be taken up for increased agriculture productivity, treatment of salinity, development of cyclone warning system, reforestation, development of water resources, air pollution control system, etc.

This research will not only be useful for India and Bangladesh but also for other South Asian countries and developing countries as well.

The pattern of food prosecutions in more recent times has remained relatively unchanged. Most have been taken under Section 2, Food and Drugs Act, 1955, even for foods which have obviously been unfit for human consumption. The Section because of its wider application has distinct procedural advantages. A few local authorities routinely use Section 8 successfully; it probably depends upon a more liberal interpretation and understanding by local justices. The five‐year study of food prosecutions, (BFJ 1971, 73, 39), separated them into a number of well‐defined groups and showed that those for the presence of foreign material were the majority and remained fairly constant throughout the period; mouldy foods increased during the five years and then remained steady as the second largest single group. The foods most commonly affected and the foreign matter commonly present could be seen; neither changed much during the period of the survey.

Despite its great practical and theoretical significance, research on how and to what extent sustainable manufacturing capabilities (SMCs) provide competitive advantage to firms remains scarce. Towards bridging the gap, this paper conducts an enquiry into the competitive value of SMCs.

A theoretical framework on the competitive value of four SMCs, namely, pollution control (PC), pollution prevention (PP), product stewardship (PS) and clean technology (CT) is developed through synthesis of literature. More specifically, competitive value is characterised in terms of enabling key resources and market positioning opportunities. A case study, using a deductive qualitative approach is conducted to test the framework by analysing reported sustainable manufacturing practices (SMPs) of three multinational firms. Observed compliances and deviations to the framework are analysed and accordingly few propositions are framed.

The empirical findings largely support the conceptualisation of competitive value for PC, PP, PS and CT provided in the theoretical framework. However, a few deviations were observed for PC, PP and PS. For instance, some PC-based actions, such as co-processing and implementation of zero liquid discharge technology show characteristics of resource conservation and lead to cost benefits. Similarly, there were instances when PP demonstrated the use of non-tacit (imitable) resources and PS was employed to seek compliance to environmental regulations.

The results based on limited number of case firms may not be generalisable to other sectors and contexts.

The study provides guidance to the manufacturing managers about the competitive value of SMPs.

This is a novel study that empirically investigates the competitive value of SMCs by understanding the associated sustainability impetus, enabling key resources and market positioning opportunities.

The aim of this paper is to provide basic information on the types of particulate cyclones separators used in the chemical and process industries, their principles of operation and factors affecting their performance.

A general review of the types of particle cleaning cyclones used in the chemical and process industries was carried out and the principles guiding their operation and performance discussed. Information which could aid the choice of cyclone for new applications is also discussed.

It was concluded that the choice of cyclone for any application is associated with a trade‐off between two contrasting performance indicators (collection efficiency and pressure drop). Adequate and accurate data gathering is essential right from the design stage for smooth operation of cyclone.

The paper highlights the general principle of operation of cyclone separators and the factors that affect their performance.
