Coprocessamento na Indústria de cimento do Ceará: avaliação do potencial de uso de pneus inservíveis e resíduos de biomassa

Abstract

The co-processing of residues represents an alternative to the final disposal of several types of industrial waste due to the fact that it consists in a more adequate form of disposal from an environmental point of view. The cement industry requires large amounts of fuel for the cement production process, and benefits from the need of waste disposal by other industries due to having the means to effectively provide the destruction of such waste at the same time that it uses them as complementary fuel, in addition to being able to use the waste as an alternative raw material. This study was carried out in order to analyze the potential of using unserviceable tires and biomass, rice husk and babassu bark, for co-processing purposes in cement industries in the state of Ceará. Among the objectives of the study are: to carry out a review of the cement manufacturing process and to evaluate the panorama of the cement industry, state and nationwide; compare technical features between the residues studied and traditional fossil fuels used in the industry, and verify the feasibility of using the residues studied at cement factories in the state of Ceará.
