The disposal of industrial waste to the technology of co-processing in cement kilns is effective and proven worldwide for its environmental benefits. However, the waste most of the time must be adequate so that the feed does not damage the normal production process in a cement plant. In this way, companies of adaptation of this waste, called blenders, receive the waste in its raw form and the employees of these companies are responsible for unloading and handling them until final suitability for their use as substitutes for fuels or raw materials In cement kilns. These employees may be exposed to a wide range of chemical risks, often unmapped, such as organic compounds. The analysis of environmental waste based on heavy metals and physical analyzes (particle size, pH, among others) and organic compounds may be neglected. We must also consider the high cost for samples and analyze all organic chemical compounds present and toxic to the worker. The objective of this study was to define which minimum organic compounds should be analyzed and to apply this study, choosing a representative organic compound in health and safety aspects of the workers to apply this analysis in a case study in a blendeira in the metropolitan region of Curitiba evaluating The health and safety aspects of the work of the operators of this plant. The importance of this work was to show that there are chemical compounds not studied in the handling of industrial waste, whose employees may be exposed to risks related to occupational health and unmanaged security. |
