This work proposes and appreciates the use of content analysis techniques on dilemmas involving economic growth and environmental sustainability. To achieve this purpose, uses the asbestos issue, through the exam of specialists’ communications in a public audience on the Federal Supreme Court, in which the unconstitutionality of the State law that forbids the utilization of this material. The specialists who were called by the Supreme Court are divided between those who admit the possibility of its safe use and the ones who preach its ban and their speeches are studied based on the differences between the different kinds of asbestos, serpentine and amphibole. Additionally, are considered the social costs of its maintenance in terms of health and social security and the costs involved in its substitution in terms of job positions, income and derivative products’ prices. The content analytical techniques proved adequate to the evaluation of speeches and communications between currents with distinct positioning in terms of sustainability and development.
Asbestos is the trade name of material widely used in construction, especially in BRICS members. The high usage of asbestos due to its low cost coupled with their properties, such as electrical resistance, tensile strength, heat resistance and some acids, in addition to its flexibility derived from its fibrous feature, which allows it to be woven. However, it is also known that asbestos in the process of extraction and production is extremely dangerous for workers. Very thin fibers tend to turn into powder that is deposited in the lungs of workers, which may lead to loss of breathing capacity, pleural plaques, some cancers, and most often a disease called asbestosis. Although there is a tendency to ban asbestos in all regions and countries, as already occurs in the European Union, Brazil, and other countries with large housing deficit, maintains the use of asbestos in the production of fiber cement tiles. The article aims to discuss the dilemma of controlled use and ban asbestos, and present the progress of the search for alternative materials to asbestos in Brazil.
