Abstract
Purpose
Cement industry for both developed and developing countries is important from the economic point of view. It is playing a vital role in economic development of a developing country like Pakistan. However, these industries are posing threat to the environment, human health and plant species. The purpose of this paper is to identify the most critical factors of cement industry that have a negative impact on the environment, human health and plant species in the context of Pakistan.
Design/methodology/approach
The factors are categorized into air pollution, noise pollution, soil pollution, human health and plant species. These factors are categorized on the basis of previous literature and environmental safety reports. Air pollution is caused by iron and sulphur while noise pollution is mainly caused by crusher room and rotatory kiln end. The soil is being polluted by zinc and lead while human health and plant species are being damaged by sulphur dioxide and nitrogen dioxide. For the analysis purpose, a multi-criteria decision-making (MCDM) technique, i.e., decision-making trial and evaluation laboratory (DEMATEL) is used.
Findings
The result shows that the major cause of air pollution is “sulphur” while “crusher room and rotatory kiln end” are responsible for noise pollution. On the other hand, “mercury” is responsible for causing soil pollution while human health and plant species are influenced by the toxic effect of “nitrogen dioxide.”
Research limitations/implications
The results obtained are specific to cement manufacturing industry of Pakistan and cannot be generalized for any other manufacturing sector.
Practical implications
The proposed methodology shows the most critical factors toward which concertation should be given for mitigating their impact. This study will help the government and the cement industry to focus on all those elements that are the most responsible for causing different types of pollution.
Originality/value
No such work is reported in previous research that proposes a framework using DEMATEL technique for analysis of critical factors of cement industries that have a dangerous impact on the environment and human health, especially in a developing country, like Pakistan.

Abstract
Purpose
The goal of this study is to further the existing understanding of the diverging pollution prevention and occupational and safety practices undertaken in the Mexican maquiladora industry in order to promote the creation of a sustainable production system.
Design/methodology/approach
This study explores in detail the occupational health, safety and environmental practices performed by six electronic maquiladoras located in the State of Sonora, Mexico. The OSHA's program evaluation profile (PEP) and cleaner production and pollution prevention and worker surveys were the instruments used for collecting information. All instruments were complemented with short interviews and walkthroughs in the production lines.
Findings
Evidences from this study suggest that today's trends in maquiladoras production patterns continue to go in an unsustainable direction because of the lack of good environmental and occupational and safety practices.
Practical implications
This study reveals the most telling and significant sustainability themes associated to the maquiladora industry that holds the exciting potential of protecting the environment and labor and strengthening economic growth through more efficient and sustainable production.
Originality/value
Sustainability production is an issue that is often neglected into the actual stock of published material about maquiladoras. This study fills this gap through a broad structural approach that takes into account economic, social, and environment aspects as a way to helping the adoption of sustainability practices in the maquiladora industry.

Abstract
Examines the thirteenth published year of the ITCRR. Runs the whole gamut of textile innovation, research and testing, some of which investigates hitherto untouched aspects. Subjects discussed include cotton fabric processing, asbestos substitutes, textile adjuncts to cardiovascular surgery, wet textile processes, hand evaluation, nanotechnology, thermoplastic composites, robotic ironing, protective clothing (agricultural and industrial), ecological aspects of fibre properties – to name but a few! There would appear to be no limit to the future potential for textile applications.

Abstract
Purpose
This study investigates the level of variance in the real time demand for bagged cement, induced in response to the climatic sequence of the humid tropics, to support best practice calls for a weather-responsive supply chain strategy.
Design/methodology/approach
Data on the consumption of cement and site works for 100 ongoing building construction sites were gathered for a period of 12 months. The variance partitioning capabilities of the Ordinary Least Squares and Hierarchical Linear Modelling forms of regression analysis are comparatively used to evaluate the sensitivity of cement demand to the meteorological profile of wet-humid climate
Findings
The study outcome provides statistical evidence demonstrating that the meteorological profile of wet-humid climate induces a significantly high percentage of the variance in the real-time demand for bagged cement on construction sites. However, nested within this variance, are the fixed effects of the cement footprint of the building architecture inherent in the locality. Particularly, positive changes to reduce the wet trade composition of buildings or compensating changes in technological bias, are necessary to combat weather interference in the humid tropics.
Research limitations/implications
The findings are exploratory, and not for the purposes of holistically forecasting cement demand, and can therefore only form part of a more comprehensive decision support system, bespoke to the study area.
Practical implications
The study outcome provides a back-end view to climatic adaptation in wet humid settings, making a compelling case for localized climate-risk adaptive supply chain strategies and policies geared towards sustainability in cement usage.
Originality/value
The study delineates the confounding impact of weather, distinct from local building architecture and technological bias, thus creating a methodological platform for replication and comparative productivity studies in diverse geographical areas.

Abstract
Purpose
This paper has been produced to enumerate and discuss threats which are caused by industry and may affect health in the province of Kocaeli.
Design/methodology/approach
Industries in the province, depending on their function, were grouped into sectors. Air, water and solid waste pollutants produced by each sector were assessed for each region of the province.
Findings
Of the 7,400 industries in the province, only 1,198 are registered with the Kocaeli Chamber of Industry and of this number only a minority are subject to controls by the Ministry of the Environment through the Kocaeli Provincial Directorate of the Environment (KPDE). Data on pollutants were obtained from the KPDE. Liquid waste was controlled in 370 firms (5 per cent) of all industries in the province, air quality in 444 (6 per cent) and dangerous waste in 4 (0.06 per cent). A total of 41 firms were designated as having dangerous pollution profiles.
Practical implications
These figures suggest that industrial development in the province of Kocaeli has not been accompanied by adequate environmental protection. Stricter control for present and future industries is urgently required. Attention must also be directed at zoning industrial and residential areas to safeguard human health and the environment.
Originality/value
Provides information on environmental threats caused by industry in Turkey.

Abstract
For most people, especially those with fixed incomes, household budgets have to be balanced and sometimes the balance is precarious. With price rises of foods, there is a switch to a cheaper substitute within the group, or if it is a food for which there is no real substitute, reduced purchases follow. The annual and quarterly reviews of the National Food Survey over the years have shown this to be so; with carcase meat, where one meat is highly priced, housewives switch to a cheaper joint, and this is mainly the reason for the great increase in consumption of poultry; when recently the price of butter rose sharply, there was a switch to margarine. NFS statistics did not show any lessening of consumer preference for butter, but in most households, with budgets on a tight string, margarine had to be used for many purposes for which butter had previously been used. With those foods which have no substitute, and bread (also milk) is a classic example, to keep the sum spent on the food each week about the same, the amount purchased is correspondingly reduced. Again, NFS statistics show this to be the case, a practice which has been responsible for the small annual reductions in the amount of bread consumed per person per week over the last fifteen years or so; very small, a matter of an ounce or two, but adequate to maintain the balance of price/quantity since price rises have been relatively small, if fairly frequent. This artifice to absorb small price rises will not work, however, when price rises follow on one another rapidly and together are large. Bread is a case in point.
