The cement industry is a capital intensive, energy consuming, and vital industry for sustaining infrastructure of nations. The international cement market –while constituting a small share of world industry output—has been growing at an increasing rate relative to local production in recent years. Attempts to protect the environment in developed countries –especially Europe—have caused cement p...

This paper provides a critical analysis of the ISO 14001 Environmental Management System (EMS) deployed at Tecnosol Comércio e Serviços Ltda., partner of Holdercim Brasil S.A, a cement group. The main activity of Tecnosol is co-processing industrial waste in the synthesis kiln at the Alvorada cement plant, in the municipality of Cantagalo, Rio de Janeiro, Brazil. The purpose of co-processing in...

Many years of experience in several industries have shown that the use of wastes as alternative fuels in cement plants is both ecologically and economically justified. However, there are several factors that need assessment before using alternative fuels. Further, availability and cost are important factors too. Along with other alternative fuels, literature and case studies have revealed that ...

Air pollution has assumed a mammoth proportion in recent times because of causation of health hazards and loss of economic productivity of crop plants. The present study was carried out to assess the impact of cement klin dust pollution on some selected legume crops viz. Arachis hypogaea, Vigna mungo, V. radiate, Dolichos lablab and Cajanus cajan which are grown around the cement industry. Effe...

Cement dust exposure has previously been associated with airway symptoms and ventilatory impairment. The aim of the present study was to examine lung function and airway symptoms among employees in different jobs and at different levels of exposure to thoracic dust in the cement production industry. At the start of a 4-yr prospective cohort study in 2007, exposure to cement dust, symptoms and l...

Pyrite cinders, which are the waste products of sulphuric acid manufacturing plants, contain hazardous heavy metals with potential environmental risks for disposal. In this study, the potential use of pyrite cinders (PyCs) as iron source in the production of Portland cement clinker was demonstrated at the industrial scale. The chemical and mineralogical analyses of the PyC sample used in this s...

The most advanced cement manufacturing technology does not, on its own, guarantee profitable operations. The cement manufacturing operation for maximum cost efficiency not only requires the advanced technological design but also sound operational practices. Operational Audit is an effective way for enhancing the productivity and minimising energy consumption. The objectives of a comprehensive o...

The dusty challenge Obtaining reliable level measurement has traditionally been a severe challenge because cement production is such a dusty process. During homogenization, for example, silos are continuously filled and emptied, and the component materials are constantly aerated to ensure good mixing. This creates a tremendous amount of dust that makes it difficult to obtain reliable readings w...
